选择性激光治疗周边视网膜裂孔

目的:评价选择性激光光凝治疗视网膜周边裂孔的疗效。方法:眼前有闪光感、飞蚊症状但无视野缺损的视网膜周边裂孔38例44眼,排除周边裂孔及变性范围超过2个象限的病例,采用氩离子激光照射病变区域周围或后缘2～3排光凝斑;观察裂孔愈合情况及病情转归。结果:平均随访16个月,43眼裂孔封闭,治疗前后视力及视野均无变化,未见明显并发症。1眼视网膜下液扩展,通过巩膜冷凝及外加压手术治愈。结论:激光光凝治疗周边视网膜裂孔及变性是一安全可靠的方法,选择适当的病例有助于减少并发症。

Selective Laser Photocoagulation for the Treatment of Peripheral Retinal Breaks

Objective:To evaluate the effectiveness of selective laser photocoagulation treatment for the peripheral retinal breaks. Methods:44 eyes in 38 patients of peripheral retinal breaks accompanied with eye flashing or/and vitreous floaters were included in this study, all the eyes were precluded visual defect and extensive retinal degeneration over 2 quadrants. Double or triple rows of argon laser burns were applied around or behind the posterior rim of the lesion if it was too peripheral. Results: During the mean follow-up period of 16 months, no change in visual acuity and visual field was noted after treatment as compared with those of before treatment in 43 eyes, and no complication was observed in these eyes. The subretinal fluid progressed in 1 eye so the cryopexy and scleral buckling surgery were intervened. Conlusion: Laser photocoagulation is an efficacious method to treat the peripheral retinal breaks and degenerations . Complications could be reduced to a minimum in selective patients.
