To report four cases of branch retinal vein occlusion (BRVO) with the complication of serous retinal detachment (SRD).
We retrospectively studied four eyes of four patients with macular edema and macular hard exudates associated with midperipheral BRVO. Visual acuity, ophthalmoscopy, fluorescein angiography, and optical coherence tomography findings were evaluated. Three of the four eyes underwent laser photocoagulation in the BRVO area 1 month after the initial visit.
Macular edema consisted of SRD without cystoid macular edema in all eyes. Late-phase fluorescein angiography showed extensive dye leakage in the BRVO area. When SRD was resolved 4 months after the initial examination, hard exudates had increased in the macular area. Although macular hard exudates decreased 1 year after the initial examination, visual acuity remained under 20/20 because of macular atrophy.
SRD is one type of macular edema observed in BRVO. In macula-spared midperipheral BRVO, the SRD originates from a vascular leaking area, and there is a high risk that massive macular hard exudates will develop, which may affect visual recovery.
报告4例视网膜分支静脉阻塞（BRVO）并发浆液性视网膜脱离（SRD）的病例。
我们回顾性研究了4例患有黄斑水肿和黄斑硬性渗出且伴有中周部BRVO的患者的4只眼。评估了视力、检眼镜检查、荧光素血管造影和光学相干断层扫描结果。4只眼中的3只在初次就诊1个月后在BRVO区域进行了激光光凝治疗。
所有眼中的黄斑水肿均由无黄斑囊样水肿的SRD组成。晚期荧光素血管造影显示BRVO区域有广泛的染料渗漏。初次检查4个月后SRD消退时，黄斑区的硬性渗出物增多。尽管初次检查1年后黄斑硬性渗出物减少，但由于黄斑萎缩，视力仍低于20/20。
SRD是BRVO中观察到的一种黄斑水肿类型。在黄斑未受累的中周部BRVO中，SRD起源于血管渗漏区域，且有很高的风险会出现大量黄斑硬性渗出物，这可能会影响视力恢复。
