目的:探讨1眼视网膜脱离复位术后,对侧眼有周边视网膜变性或伴有干性裂孔的患者进行预防性视网膜激光光凝术的疗效观察。方法:对符合上述条件的患者,常规行散瞳三面镜或间接眼底镜检查,对明确有对侧眼周边视网膜变性(格子样变性、霜样变性、囊样变性等)或伴有干性裂孔的192例行预防性视网膜激光光凝术。结果:接受预防性视网膜激光光凝术的192例患者对侧眼的眼底周边视网膜变性区或干性裂孔区封闭良好,色素斑形成明显。光凝术后随访6～18mo,所有患者均无发生孔源性视网膜脱离。结论:对眼底有周边视网膜变性或伴有干性裂孔的患者行预防性视网膜激光光凝术能有效防止视网膜脱离的发生。

·AIM:To evaluate the effect of the preventive retinal laser photocoagulation on the following eye in patients with peripheral retinal degeneration or associated with dry holes after retinal detachment operation.·METHODS:Patients who met the above conditions were evaluated for the presence of vitreoretinal changes using Goldman three-mirror contact len or indirect ophthalmoscopy.192 cases in contralateral eyes with peripheral retinal degeneration(lattice degeneration,snail track degeneration,cystic degeneration,etc.)or associated with dry holes received the preventive retinal laser photocoagulation.·RESULTS:The areas of peripheral retinal degeneration or dry holes in the following eyes of 192 patients who received the preventive retinal laser photocoagulation were closed well,and the pigment spots were sharp.All cases who had been treated by laser photocoagulation were followed up for 6-18 months.No retinal detachment was found.·CONCLUSION:The preventive retinal laser photocoagulation on peripheral retinal degeneration or associated with dry holes is effective to prevent the occurrence of retinal detachment.·
