Effects of infestation by Rhipicephalus sanguineus on lymphocyte blastogenic responses to mitogens in dogs

AIMS: To determine the effect of modified macular grid photocoagulation in patients with refractory macular oedema due to uveitis or cataract extraction. METHODS: In this study 20 patients with macular oedema underwent modified macular grid laser photocoagulation and were followed by means of standardised examinations (day 0, months 2, 6, and 12) consisting of best corrected visual acuity and fluorescein angiography. RESULTS: The mean visual acuity increased from 0.16 before to 0.3 after laser treatment (p = 0.013), and fluorescein leakage was significantly reduced (p = 0.005). Visual prognosis was influenced by duration of the uveitis, not by sex or age. CONCLUSION: Modified macular grid laser photocoagulation had a beneficial effect on macular oedema caused by uveitis or the Irvine-Gass syndrome. A prospective, randomised study is needed to determine the exact place of modified macular grid photocoagulation in the treatment of patients with inflammatory or postsurgical macular oedema.
