目得：为了提供证据证明视网膜分支静脉阻塞的成功光凝治疗减少黄斑水肿后，视网膜中的硬性渗出物沉淀可以发生，方法：一名59岁女性接受氩激光视网膜光凝治疗视网膜分支静脉阻塞，主要涉及视网膜充血区域，眼底变化通过眼底照相和光学相干断层扫描记录。治疗前，广泛的视网膜内水肿伴空洞形成和小的浆液性中心凹脱离延伸到视网膜充血区域之外。治疗后三个月，所有的视网膜增厚已经消失，但一个显着增加量的intraretinal硬渗出物被视为相邻的treated areas.CONCLUSIONS：沉淀的硬渗出物可以发生后，减少黄斑水肿成功的视网膜光凝治疗，大概是因为水和高度可溶性电解质的吸收速度比脂质。这种现象应与疾病进展导致的硬性渗出物积聚相区别。(C)1998年，Elsevier Science Inc.

PURPOSE: To present evidence that precipitation of hard exudate in the retina can occur after reduction of macular edema by successful photocoagulation treatment for retinal branch vein occlusion,METHODS: A 59-year-old woman received argon laser retinal photocoagulation treatment for retinal branch vein occlusion over the primarily involved engorged area of the retina, Fundus changes were documented by fundus photography and optical coherence tomography,RESULTS: Before treatment, an extensive intraretinal edema with cavity formation and a small serous foveal detachment extended outside the engorged area of the retina. Three months after treatment, all retinal thickening had disappeared, but a markedly increased amount of intraretinal hard exudate was seen adjacent to the treated area.CONCLUSIONS: Precipitation of hard exudate can occur after reduction of macular edema by successful retinal photocoagulation treatment, presumably because water and highly soluble electrolytes are resorbed faster than lipids. This phenomenon should be distinguished from accumulation of hard exudate resulting from disease progression. (C) 1998 by Elsevier Science Inc. All rights reserved.
