激光脉络膜切开视网膜下放液的临床观察

目的 探讨激光脉络膜切开与冷针穿刺脉络膜视网膜下放液的安全性及效果。 方法 孔源性视网膜脱离需行巩膜扣带术的病例70例74只眼，随机分为两组，A组34例36只眼采用冷针穿刺脉络膜放液，B组36例38只眼采用半导体激光眼内激光探头光凝脉络膜放液，比较两种方法的效果及并发症发生情况。 结果 两种放液方法均获成功，冷针穿刺脉络膜放液发生视网膜下出血3例、1例视网膜嵌塞、视网膜穿孔，而激光脉络膜切开放液组未发生明显的并发症。 结论 半导体激光脉络膜切开视网膜下放液可以降低并发症发生率，适用于任何需视网膜下放液的病例，尤其在视网膜下液不多的病例。 (中华眼底病杂志,1998,14:202-203)

Clinical observation on diode laser choroidotomy for drainage of subretinal fluid

Purpose To evaluate the safety and efficacy of draining subretinal fluid with transchoroidal probing by using the traditional needling and diode endolaser probing.Methods The investigation included 70 consecutive patients(74 eyes) with rhegmatogenous retinal detachment undergoing scleral buckling surgery.Seventy cases were randomly divided into 2 groups,group A 34 cases(36 eyes)with the needle drainage procedure and group B 36 cases(38 eyes) with the diode probe respectively.The safety and efficacy were compared in between the 2 groups.Results No operative failure was found in these 2 groups.In group A,subretinal hemorrhage occurred in 3 eyes,and retinal incarceration,retinal preforation in one eye. No significant complication occurred in group B.ConclusionDiode laser drainage has the advantage in that it may reduce the incidence of operative complication with drainage.This technique might be used in any case requiring drainage of subretinal fluid especially of rhegmat　ogenous retinal detachment in cases of shallow retinal detachment. (Chin J Ocul Fundus Dis,1998,14:202-203)
