Distressed or relieved? Psychological side effects of breast cancer screening in The Netherlands

PURPOSE: To compare three methods of combined cataract extraction and glaucoma surgery. METHODS: Retrospective review of 35 eyes of patients who had extracapsular cataract extraction and trabeculectomy using a corneoscleral incision (SAME), 54 eyes undergoing extracapsular cataract extraction and trabeculectomy using a separated corneal incision for cataract extraction and 43 eyes undergoing phacoemulsification and trabeculectomy. RESULTS: Ninety-one percent of the eyes in the SAME group, 85% of the SEPARATE group and 97% of the phacoemulsification and trabeculectomy group had an IOP < 22 mmHg at 6 months with or without medication (NS). Postoperative visual acuity and astigmatism were not significantly different between the groups. The number of eyes requiring YAG laser capsulotomy was significantly greater in the extracapsular cataract extraction and trabeculectomy (same and separated incision) as compared to the phacoemulsification and trabeculectomy group (P < 0.001). CONCLUSION: Phacoemulsification and trabeculectomy was not significantly more successful than the other methods of combined surgery. Although complication rates were similar, visual rehabilitation was faster and there was a reduced incidence of early posterior capsule opacification.     

Secondary cataracts in extreme myopia

INTRODUCTION: After cataract surgery there is a higher incidence of posterior capsular opacification (secondary cataract) in myopia than in normal population, and it varies from 40 to 60% [1, 2]. METHODS: Fifty myopic eyes operated for cataract at Prof. Dr. Ivan Stankovitsh Eye Department from 1988 to 1995 were examined for capsular opacification (secondary cataract). Extracapsular cataract extraction was performed in all patients and in 32 patients the posterior intraocular lens was placed. Capsular opacification was classified by type and treated with Nd:YAG laser or discussion at least 9 months to 3 years and 3 months from the operation. RESULTS: There were 13 secondary cataracts (26%) in our series of patients, of whom 22% with intraocular lenses, and 33% were aphakic patients. Visual acuity was 4/60 to 0.5. In 11 patients YAG-laser capsulotomy was performed and in one patient capsular discussion, and in one subject there was no treatment. Consequent visual acuity was 0.3 to 1.0. No correlation was found between the age, type of intraocular lens and capsular opacification. DISCUSSION: Capsular opacification is more often seen in myopic eyes and its treatment is associated with a higher rate of complications (cystoid macular oedema, rupture of anterior hyaloid, retinal detachment...) [3, 4]. It seems that posterior lens implants reduce the chance for development of posterior capsular opacification. The safest treatment is YAG-laser capsulotomy.     

Randomized clinical trial of a new dexamethasone delivery system (Surodex) for treatment of post-cataract surgery inflammation

OBJECTIVE: To evaluate the safety of Surodex Drug Delivery System (Oculex Pharmaceuticals, Inc., Sunnyvale, CA) containing dexamethasone 60 micrograms, for use in cataract surgery, and to compare its anti-inflammatory efficacy with conventional dexamethasone 0.1% eyedrops. DESIGN: Randomized, masked, and partially controlled trial. PARTICIPANTS: Sixty eyes of 60 Asian patients undergoing extracapsular cataract extraction with intraocular lens implantation were examined. Of these, 28 eyes of 28 patients served as control eyes. Patients were stratified for age and presence of diabetes mellitus. INTERVENTION: Surodex was inserted in the anterior chamber of 32 eyes at the conclusion of surgery. These eyes received placebo eyedrops four times a day after surgery for 4 weeks. Control eyes received neither Surodex nor a placebo implant but were prescribed conventional 0.1% dexamethasone eyedrops four times a day for 4 weeks. MAIN OUTCOME MEASURES: Anterior chamber cells and flare were clinically graded at the slit lamp. Anterior chamber flare was objectively assessed with the Kowa FM500 Laser Flare Meter (Kowa Co. Ltd, Tokyo, Japan) for up to 3 months after surgery. Intraocular pressure and corneal endothelial specular microscopy with morphometric cell analysis were performed for up to 1 year after surgery. RESULTS: Clinical slit-lamp assessment of anterior chamber flare and cells showed no difference between Surodex-treated eyes and dexamethasone eyedrop-treated eyes. Flare meter readings showed lower flare levels in the Surodex group at all postoperative visits compared with the dexamethasone eyedrop group. Flare reduction in the Surodex group reached statistical significance at days 4, 8, 15, and 30 after surgery. At 3 months, flare was reduced to preoperative levels in the Surodex group but was still raised in the dexamethasone eyedrop group. Five eyes in the dexamethasone eyedrop group required augmentation of steroids and were deemed therapeutic failures as opposed to one eye in the Surodex group. One patient in the dexamethasone eyedrop group developed postoperative open-angle glaucoma with profound visual field loss and optic disc cupping, resulting in hand movements vision. No significant difference in endothelial cell loss was noted between Surodex-inserted eyes and dexamethasone eyedrop-treated eyes for up to 1 year after surgery. CONCLUSIONS: Intraocular placement of a single Surodex is a safe and effective treatment method to reduce intraocular inflammation after cataract surgery. There was no statistical difference in efficacy between Surodex and 0.1% dexamethasone eyedrops in reducing intraocular inflammation, as measured by clinical methods, while Surodex was clearly superior to eyedrops in reducing aqueous flare as objectively assessed with the laser flare meter.     

Outcome of combined trabeculectomy with cataract operation and intraocular lens implantation

BACKGROUND: When trabeculectomy and cataract extraction with intraocular lens insertion are combined, do the success and complication rates add. MATERIAL AND METHODS: Follow-up of 47 eyes of 34 patients with combined trabeculectomy and cataract extraction with intraocular lens implantation after 12 to 42 months. RESULTS: With a low perioperative complication rate the intraocular pressure after one year was below 22 mm Hg in 90% without any medication and in 98% additional glaucoma therapy. After 2 and 3 years the intraocular pressure was normal without any additional therapy in 83% of the eyes. The visual acuity was better or equal to the preoperative value in 89% of the cases. CONCLUSIONS: The combination of trabeculectomy and of cataract extraction with intraocular lens implantation has a low complication rate and gives good results regarding intraocular pressure and visual rehabilitation. When a trabeculectomy is indicated, the indication for a simultaneous cataract extraction with intraocular lens implantation should not be to restricted.     

Involvement of macrophage scavenger receptors in protection against murine malaria

OBJECTIVE: This study aimed to determine whether heparin surface-modified (HSM) intraocular lenses (IOLs) with a hydrophilic surface would reduce cell adherence and other postoperative changes compared with the conventional polymethylmethacrylate (PMMA) IOLs in patients with either diabetes mellitus or inactive uveitis. DESIGN: The study design was a randomized, double-masked, clinical trial. PARTICIPANTS: Twenty-five patients with bilateral cataracts, 14 with inactive anterior uveitis and 11 with diabetes, with an age range of 11 to 81 years (mean, 52.8 years) participated. INTERVENTION: Bilateral cataract extraction with posterior chamber IOL implantation was measured, each patient receiving an HSM lens in one eye and a PMMA lens in the other. Pharmacia one-piece HSM and PMMA IOLs were used. Postoperative ocular changes were evaluated at regular intervals for 24 months in patients with inactive uveitis and for 6 months in patients with diabetes. Patients and physicians alike were unaware of which eye contained which lens until postoperative results were compiled. Records were kept by a study coordinator. MAIN OUTCOME MEASURES: Comparisons of posterior synechiae, IOL cellular deposits, and posterior capsular fibrosis between PMMA and HSM IOLs were measured. RESULTS: Using the chi-square test, no statistically significant difference was found between the HSM and PMMA IOLs in the number of cellular deposits found on the anterior IOL surface, the number of adhesions between the iris and IOL, or the incidence of capsular opacification. CONCLUSION: The HSM and PMMA IOLs showed similar postoperative results in patients with inactive uveitis or diabetes mellitus.     

Prospective evaluation of corneal endothelial cell loss after pediatric cataract surgery

PURPOSE: To study the alterations in endothelial cell count and morphology after pediatric cataract surgery using currently practiced techniques. SETTING: L.V. Prasad Eye Institute, Hyderabad, India. METHODS: In a prospective nonrandomized series comprising 20 eyes of 14 children with congenital or developmental cataract, endothelial cell loss from cataract surgery was evaluated. Mean patient age was 9.3 years (range 5 to 15 years). Extracapsular cataract extraction (ECCE) with intraocular lens (IOL) implantation was performed in 11 eyes (Group 1). Primary posterior capsulotomy and anterior vitrectomy were performed with ECCE and IOL implantation in 9 eyes (Group 2). Noncontact specular microscopy was done preoperatively and 6 to 8 and 24 to 36 weeks postoperatively. Endothelial cell loss, alteration in the coefficient of variation, and the change in the number of hexagonal cells were determined by semiautomated analysis of endothelial pictures. RESULTS: Mean endothelial cell loss was 198.39 cells/mm2 (5.28%) in Group 1 and 295.17 cells/mm2 (7.50%) in Group 2 at 24 to 36 weeks. There was no statistically significant difference in alteration in endothelial cell count and morphology between the 2 groups. CONCLUSIONS: The results suggest that endothelial cell loss with currently practiced techniques of pediatric cataract surgery is within acceptable limits.     

Combined cataract-glaucoma operations. Extracapsular extraction and trabeculectomy versus phacoemulsification and trabeculectomy

This retrospective study was conducted to evaluate the results of Combined Surgery of Cataract and Glaucoma (triple procedure). The procedure of combined surgery were trabeculectomy and extracapsular extraction (14 eyes) versus trabeculectomy and phacoemulsification (15 eyes). The follow-up of both groups was at least 9 months and up to 16 months (mean: 12 months). The mean decrease of IOP was 12.4 mmHg and 8.9 mm Hg in the first and second group respectively. Instillation of Beta-blockers twelve months after surgery were more frequent in the first group (64.3%) than in the second (26.7%). Finally, the IOP values one year after surgery were equivalent in both groups (less than 19 mmHg in 93% of cases). The mean features to emphasize the delay of recuperation of the best corrected visual acuity: one month for phacotrabeculectomy, and three months for extracapsular with trabeculectomy. The frequency of complications was low in both groups. We observed more hyphemas but less secondary cataracts in the phacotrabeculectomy group. Phacotrabeculectomy could become a reference procedure for combined glaucoma and cataract surgery.     

Diabetes in primary open-angle glaucoma patients with inferior visual field defects

We reviewed the charts of 144 randomly selected patients with primary open-angle glaucoma who had Aulhorn's stage 1, 2, or 3 visual field defects to investigate whether primary open-angle glaucoma patients with predominantly inferior visual field defects had a higher prevalence of diabetes mellitus than primary open-angle glaucoma patients without such visual field defects. Of the 59 patients with mainly inferior visual field defects in one or both eyes, 19 (32%) had diabetes mellitus, while 11 of 85 (13%) patients without such defects had diabetes mellitus. This difference was statistically significant (P = 0.0096). These results suggest that primary open-angle glaucoma patients with predominantly inferior visual field defects in one or both eyes are more likely to have diabetes and that such patients with no known history of diabetes may benefit from glucose tolerance testing to detect occult impaired glucose tolerance or diabetes mellitus.     

Incidence of retinal detachment after cataract surgery and neodymium: YAG laser capsulotomy

The objective of this retrospective study was to determine the incidence of retinal detachment (RD) in patients following cataract extraction with intraocular lens placement and after neodymium:YAG (Nd:YAG) laser capsulotomy. This study comprised 1092 patients (1168 eyes) who had cataract extraction and related procedures between January 1986 and December 1992 identified from the coding and billing database. Of the 1092 patients, 215 (244 eyes) had had Nd:YAG laser capsulotomy. Their charts were reviewed for incidence of RD, and these data were correlated with age, sex, axial length, surgical complications, and other surgical procedures done at the time of cataract extraction. The incidence of RD following phacoemulsification alone was 0.75% (6/799), with a mean time between cataract extraction and RD of 11.6 months. The cases of RD after extracapsular cataract extraction, combined phacoemulsification and trabeculectomy, combined extracapsular cataract extraction and penetrating keratoplasty, and combined phacoemulsification and anterior vitrectomy were too few to draw any conclusions. The incidence of RD following Nd:YAG laser capsulotomy was 0.82% (2/244), with a mean time of 32 months between cataract surgery and capsulotomy and 13.5 months between capsulotomy and RD. There was a statistically significant higher incidence of RD after posterior capsule rupture and anterior vitrectomy than after uncomplicated phacoemulsification (2/12 versus 6/799). In conclusion, the rate of RD after uncomplicated phacoemulsification was less than or similar to the rate found in other recent studies. It was not statistically different from the rate following phacoemulsification and Nd:YAG laser capsulotomy (0.82%). This study confirms the increased risk of RD following posterior capsule rupture and anterior vitrectomy.     

Elschnig pearl formation along the posterior capsulotomy margin after neodymium:YAG capsulotomy

PURPOSE: To determine the incidence of Elschnig pearl formation along the capsulotomy margin (string of pearls) after neodymium:YAG (Nd:YAG) laser posterior capsulotomy and to elucidate its clinical features, predisposing factors, effect on visual function, and association with additional capsulotomy. SETTING: Keio University Hospital, Tokyo, Japan. METHODS: The records of 418 eyes that had had Nd:YAG posterior capsulotomy after cataract surgery were retrospectively reviewed. Of those, 315 were excluded for short follow-up (fewer than 12 months) or insufficient clinical examination data. In the remaining 103 eyes, the incidence of string of pearls was calculated, and its clinical features, predisposing factors, effect on visual function, and correlation with additional capsulotomy were evaluated. RESULTS: String of pearls was identified in 49 eyes (47.6%); 37 (75.5%) developed pearls within 1 year after Nd:YAG capsulotomy. The incidence was significantly higher in patients having intraocular lens implantation and continuous curvilinear capsulorhexis (CCC) than in those without (95.9 versus 61.1% and 97.9 versus 55.6%, respectively). No significant differences were found in patient age and sex, total Nd:YAG energy, and the presence of diabetes mellitus or high myopia. String of pearls caused visual disturbances in 17 eyes (34.7%). The rate of repeat capsulotomy was higher in patients with string of pearls than in those without (36.7 and 9.3%, respectively). CONCLUSIONS: String of pearls formation was a common and significant complication after Nd:YAG posterior capsulotomy. Intraocular lens implantation and CCC may promote its formation.     

Secondary intraocular lens implantation after cataract surgery in children

PURPOSE: To report results of secondary intraocular lens implantation after cataract surgery in children. METHODS: We reviewed clinical records for a 5-year period of patients who had cataract surgery in childhood and received a secondary intraocular lens implant. We studied indications for secondary intraocular lens placement; surgical procedures for intraocular lens implantation; preoperative and postoperative visual acuity, refractive error, and binocular status; and complications of the procedure. RESULTS: A secondary intraocular lens was placed in 28 eyes of 25 patients who had cataract surgery in childhood. In 20 eyes, the lenses were placed in the ciliary sulcus. The other eight eyes had insufficient capsular support for an intraocular lens; in two, the intraocular lens was placed in the anterior chamber and, in six, in the posterior chamber with suture fixation to the sclera. Twenty of 28 eyes (71%) had measurable improvement in visual acuity; only one eye had a decrease in visual acuity of 2 lines. Fifteen patients (54%) had a final refraction within 1.50 diopters of the fellow eye; 21 (75%) were within 3.00 diopters. During follow-up, two eyes developed glaucoma. One had transient pressure elevation; one required two filtration procedures. Three patients required Nd:YAG capsulotomy. Six patients demonstrated Worth fusion at distance and near; three demonstrated 200 seconds of arc or better stereo visual acuity. CONCLUSION: Secondary placement of an intraocular lens in the posterior chamber appears to be a safe, effective alternative for correction of aphakia in the contact lens- or spectacles-intolerant child or young adult.     

A preliminary report of small incision cataract surgery by phacoemulsification

The results of 34 cases with cataract extracted by phacoemulsification were preliminarily reported. Postoperatively, they achieved corrected visual acuities > 1.0 in 24 eyes (70.59%) in one week and in 25 eyes (73.53%) after 3 months. The post-operative astigmatism showed a tendency of change from with-the-rule shifting to against-the-rule. The rate of the corneal endothelial cell loss was 13.28%. No severe intra- and post-operative complications were found. It is concluded that the small incision, slight post-operative reaction and fast visual rehabilitation inherent in phacoemulsification procedures are more beneficial to patients than the conventional extracapsular cataract extraction.     

Secondary intraocular lens implantation in children

OBJECTIVE: The study was designed to determine the visual outcome and indication of secondary posterior chamber intraocular lens (IOL) implantation. METHODS: The operation was performed on 34 eyes with aphakia in children after separation of posterior iris synechia from posterior capsule and formation of a posterior chamber space large enough to insert an intraocular lens. Based on whether the integrity of the posterior capsule was complete or not, various techniques of secondary IOL implantation were adopted. RESULTS: The follow-up periods ranged from 6 to 24 months. The results showed that 29 of the eyes (85.29%) achieved a post-operative corrected visual acuity equal to or better than that of the best corrected visual acuity before the surgery; the postoperative uncorrected visual acuities in 16 eyes (47.06%) and corrected visual acuities in 28 eyes (82.35%) reached 0.5 or better. CONCLUSION: Secondary posterior chamber IOL implantation is a safe and effective method in children who have a complete or partial posterior capsule.     

Extracapsular cataract extraction with posterior chamber lens implantation in primary angle-closure glaucoma

PURPOSE: To evaluate long-term intraocular pressure (IOP) control after extracapsular cataract extraction (ECCE) with posterior chamber intraocular lens (IOL) implantation in patients with primary angle-closure glaucoma. SETTING: Ophthalmology Department, Groote Schuur Hospital, Cape Town, South Africa. METHODS: This retrospective study comprised 17 patients (19 eyes) with primary angle-closure glaucoma who had ECCE and posterior chamber IOL implantation. Four presented initially with acute glaucoma, 5 with subacute angle-closure glaucoma, and 8 (10 eyes) with chronic angle-closure glaucoma. In all, less than half the circumference of the angle was permanently closed. The drainage angle was evaluated preoperatively and postoperatively to monitor changes in the amount of angle closure. Intraocular pressure was measured in the early and late postoperative periods. RESULTS: On the first postoperative day, mean IOP was 17.2 mm Hg, although 5 patients (26%) had an IOP rise above 21 mm Hg despite the use of perioperative topical pilocarpine gel. After a mean follow-up of 19 months, IOP remained below 22 mm Hg without medication in 13 eyes (68%) and with topical medication in 5 eyes (26%). Mean number of glaucoma medications was reduced from 1.5/eye preoperatively to 0.5/eye postoperatively. CONCLUSION: Cataract extraction with IOL implantation resulted in good long-term IOP control in patients with primary angle-closure glaucoma, suggesting that combined cataract and trabeculectomy surgery may not be necessary to achieve long-term IOP control in these patients.     

Prothrombin gene G20210-->A transition is a risk factor for cerebral venous thrombosis

OBJECTIVE: The objective of the study was to determine the long-term outcome of patients with uveitis who underwent extracapsular cataract extraction (ECCE) and posterior chamber intraocular lens (PCIOL) implantation. DESIGN: Retrospective review. PARTICIPANTS: Twenty-eight patients (36 eyes). INTERVENTION: Extracapsular cataract extraction and PCIOL implantation. MAIN OUTCOME MEASURES: Level of best-corrected Snellen visual acuity, change in visual acuity, length of follow-up, long-term findings, and complications. RESULTS: In long-term follow-up (mean, 81.4 months), 94% of eyes had visual acuity improvement compared with preoperative levels. Average change in visual acuity for all eyes was an improvement of 6.4 Snellen lines; 75% of eyes were 20/40 or better. The prevalences of cystoid macular edema (CME), epiretinal membrane (ERM), and posterior capsule opacification (PCO) were 56%, 56%, and 58%, respectively. CONCLUSIONS: Patients with uveitis who are treated with ECCE with PCIOL implantation can have successful visual results in long-term follow-up despite the prevalence of PCO or macular abnormalities such as CME and ERM.     

Results of bilateral cataract extraction with posterior chamber intraocular lens implantation in children

OBJECTIVE: A retrospective study was undertaken to evaluate long-term anatomic and visual outcomes in eyes of children who underwent bilateral intraocular lens implantation. DESIGN: The study design was a review of medical records of 24 children operated on for bilateral cataracts and posterior chamber-intraocular lenses. PARTICIPANTS: Twenty-four children operated on for bilateral cataracts by 1 surgeon between February 1980 and February 1995 were studied. INTERVENTION: Cataract extraction with bilateral posterior chamber-intraocular lens implantation was performed. MAIN OUTCOME MEASURES: Best-corrected visual acuity, visual acuity without correction, intraocular pressure, manifest refraction, and any intraoperative or postoperative complications were measured. RESULTS: At last follow-up (mean follow-up, 50.8 months; range, 10-149 months), the intraocular lens was in good position and the intraocular pressure was normal without medication in all eyes. Four years after surgery, 79.2% (19 of 24) of first eyes achieved a best-corrected visual acuity of 20/40 or better compared to 66.7% (16 of 24) of second eyes. No eye had any loss in best-corrected visual acuity. In first eyes of 3- to 8-year olds at the time of surgery, 73.3% (11 of 15) achieved a spherical equivalent within 2 diopters of the intended at 4 years after surgery compared to 80% of second eyes. In the 9- to 18-year-old group, 88.9% (8 of 9) of first eyes and 100% of second eyes achieved a spherical equivalent within 2 diopters of the intended at 4 years after surgery. Intraoperative and postoperative complications were minimal. CONCLUSIONS: Long-term anatomic and visual results have been gratifying in this series of patients with bilateral implants.     

Characteristics of cefdinir uptake by rabbit small intestinal brush-border membrane vesicles

PURPOSE: To search for changes in the presence and distribution of the cell-adhesion-related HNK-1 carbohydrate epitope after cataract extraction. METHODS: Twenty-five pseudophakic and two aphakic human autopsy eyes and, for comparison, one anterior subcapsular cataract obtained at surgery were studied with monoclonal antibodies (MAbs) HNK-1 and NC-1 to the HNK-1 epitope using the avidin-biotinylated peroxidase complex method. RESULTS: MAbs to the HNK-1 epitope constantly immunolabelled the inner connective tissue layer of the ciliary body in all pseudophakic and aphakic eyes studied. The distribution of the immunoreaction was similar to that reported for normal eyes. They also labelled the extracellular matrix in each of 18 plaques of secondary cataract on the posterior capsule, in each of 13 plaques at the rim of the capsular bag, and in the anterior subcapsular cataract. Bladder cells in each of 16 Soemmering's rings remained unlabelled. CONCLUSION: The distribution of the HNK-1 epitope in the ciliary body does not appreciably change after cataract extraction, although the accommodative demand of the eye is altered. Its presence in an anterior subcapsular cataract suggests that the epitope may be locally produced by lens epithelial cells also in secondary cataract. The epitope is associated with cell adhesion and migration, both of which may play a role in the pathogenesis of secondary cataract.     

Combined cataract extraction and thermal sclerostomy versus combined cataract extraction and trabeculectomy

We performed either a combined cataract extraction and trabeculectomy or a combined cataract extraction and thermal sclerostomy on 43 eyes. All eyes had chronic open angle glaucoma or chronic angle closure glaucoma, or a combination of the two. In our cataract/trabeculectomy group, 74% had improvement in visual acuity, 91% had normalized intraocular pressure without anti-glaucoma medications, 31% had transient postoperative hyphemas. In our cataract/thermal sclerostomy group, 61% had improvement in visual acuity, 61% had normalization of intraocular pressures without antiglaucoma medications, 17% had transient postoperative hyphemas. We could not correlate any of the complications of surgery with poor intraocular pressure results in either groups. The mechanism for the higher success rate with a combined cataract extraction and trabeculectomy as compared with a combined cataract extraction and thermal sclerostomy was not obvious after analyzing these patients.     

The frequency of secondary cataract after extracapsular cataract extraction

A complication of extracapsular cataract extraction is posterior capsule opacification (secondary cataract). In this study we found that 26.0% of patients operated for cataract with extracapsular technique were treated for secondary cataract. The average postoperative time to treatment with Nd-YAG-lasercapsulotomy was 15.2 months with a follow-up time of 34 months.     

Recurrent bleb infections

AIM: To report the patient characteristics, causative organisms, and clinical outcomes in patients with recurrent bleb related ocular infections. METHODS: The medical records of all patients diagnosed with bleb related ocular infection at the New York Eye and Ear Infirmary over a 10 year period were reviewed. Recurrent bleb infection was defined as at least two episodes of bleb purulence with or without associated intraocular inflammation separated by a quiescent period of at least 3 months. RESULTS: Recurrent bleb infections developed in 12 eyes of 12 patients (10 men, two women) a mean of 16.3 (SD 17.9) months (range 3-51 months) after the initial infection. Two patients developed a third episode 3 and 20 months, respectively, after the second infection, yielding a total of 14 recurrent infection episodes. Recurrent infection developed after trabeculectomy in 11 eyes (adjunctive 5-fluorouracil, nine eyes; mitomycin C, one eye; no antifibrosis agent, one eye) and following cataract extraction with inadvertent bleb formation in one eye. Four (36.4%) of the filtered eyes had undergone trabeculectomy at the inferior limbus. The mean follow up time from filtering surgery to the first bleb related infection was 28 months for the nine patients treated with 5-fluorouracil and 14 months for the single patient treated with mitomycin C. 11 (78.6%) cases had a documented bleb leak in the 4 week period before or at the time of recurrent infection. Topical, prophylactic antibiotics had been used in 7/14 (50%) cases. The same organism was cultured from the initial and recurrent infections in 2/14 (14.3%) cases. CONCLUSION: Eyes that have been successfully treated for bleb related infection remain at risk for recurrent infection. No apparent correlation exists between organisms responsible for the initial and recurrent infections. The increased rate of recurrent bleb related infection in patients receiving adjunctive 5-fluorouracil compared to mitomycin C may have been related to the longer follow up of the 5-fluorouracil eyes.
