To determine the relationship between macular edema associated with branch retinal vein occlusion (BRVO) and the condition of the vitreous.
The authors retrospectively studied 58 patients (58 eyes) who underwent vitreous examination. The eyes were classified as having vitreomacular attachment (VMA) or vitreomacular separation (VMS), and were divided into two groups based on the mean age of the patients.
Macular edema was found in 39 (67%) of the eyes. The prevalence of VMA was 81% (22 of 27 eyes) in group 1 (patients who were 64 years old or younger) and 45% (14 of 31 eyes) in group 2 (patients who were older than 64 years). Although no significant relationship was found, 77% (17 of 22) of the eyes with VMA in group 1 had macular edema. The incidence of macular edema was significantly higher in eyes with VMA (93%, 13 of 14) than in eyes with VMS (41%, 7 of 17, P = .009) in group 2.
The authors' findings suggest that VMA may influence the presence of macular edema associated with BRVO.
确定视网膜分支静脉阻塞（BRVO）相关的黄斑水肿与玻璃体状况之间的关系。
作者回顾性研究了58例接受玻璃体检查的患者（58只眼）。这些眼睛被分类为具有玻璃体黄斑附着（VMA）或玻璃体黄斑分离（VMS），并根据患者的平均年龄分为两组。
在39只（67%）眼睛中发现黄斑水肿。在第1组（64岁及以下患者）中，VMA的患病率为81%（27只眼中的22只），在第2组（64岁以上患者）中为45%（31只眼中的14只）。虽然未发现显著关系，但第1组中77%（22只中的17只）具有VMA的眼睛有黄斑水肿。在第2组中，具有VMA的眼睛黄斑水肿发生率（93%，14只中的13只）显著高于具有VMS的眼睛（41%，17只中的7只，P = .009）。
作者的研究结果表明，VMA可能影响与BRVO相关的黄斑水肿的存在。
