Branch Retinal vein occlusion is the most common retinal vascular disease after diabetic retinopathy in elderly populations.
To describe morphological patterns of macular edema in branch retinal vein occlusion using optical coherence tomography.
It is a hospital based; descriptive, cross-sectional study. All patients with macular edema secondary to branch retinal vein occlusion diagnosed by optical coherence tomography and fulfilling the inclusion criteria from 2017 July 1 to 2018 July 1 were studied.
A total of 84 eyes of 84 patients were enrolled. The mean age of the patient was 68.0833 ± 11.22 years (range, 35-74 years). Forty-five (53.57%) were male. Forty-four eyes had right eye involvement. Major and macular branch retinal vein occlusion was found in 50 and 34 eyes respectively. Forty eight eyes had superior and 36 eyes had inferior branch retinal vein occlusion. Morphological patterns of macular edema were classified: cystoid macular edema, cystoid macular edema with serous retinal detachment, diffuse macular edema and diffuse macular edema with serous retinal detachment of which 68 (80.95%) had cystoid macular edema. Out of 84 eyes, 30 (35.71%) had inner and outer segment (IS/OS) junction disruption.
Optical coherence tomography is a safe and noninvasive technique. Serous retinal detachment and photoreceptors disruption may go unnoticed unless OCT is performed. It can measure the changes in retinal thickness and thus predict the visual outcomes in patients with macular edema.
分支视网膜静脉阻塞是老年人中仅次于糖尿病性视网膜病变的最常见视网膜血管疾病。
使用光学相干断层扫描描述分支视网膜静脉阻塞的黄斑水肿形态模式。
这是一项基于医院的描述性、横断面研究。所有符合纳入标准的 2017 年 7 月 1 日至 2018 年 7 月 1 日期间经光学相干断层扫描诊断为分支视网膜静脉阻塞伴黄斑水肿的患者均纳入研究。
共纳入 84 例 84 只眼的患者。患者的平均年龄为 68.0833±11.22 岁（范围 35-74 岁）。45 例（53.57%）为男性。右眼受累 44 只眼。主要分支和黄斑分支视网膜静脉阻塞分别为 50 只眼和 34 只眼。48 只眼为上分支，36 只眼为下分支。黄斑水肿的形态模式分为：囊样黄斑水肿、伴浆液性视网膜脱离的囊样黄斑水肿、弥漫性黄斑水肿和伴浆液性视网膜脱离的弥漫性黄斑水肿，其中 68 只眼（80.95%）为囊样黄斑水肿。84 只眼中，30 只眼（35.71%）出现内、外节（IS/OS）连接中断。
光学相干断层扫描是一种安全、非侵入性的技术。除非进行 OCT 检查，否则可能会忽略浆液性视网膜脱离和光感受器破坏。它可以测量视网膜厚度的变化，从而预测黄斑水肿患者的视力结果。
