PURPOSE
To examine the topographic distribution of the origin of diabetic retinal neovascularization.
METHODS
The eyes of 3,121 patients with background diabetic retinopathy were investigated. These patients were volunteers in systemic medical therapy experiments. Color stereo photographs were obtained annually. The first retinal neovascularization sites were identified and the distances from the optic nerve measured.
RESULTS
In 1 year, neovascularization originated in 282 eyes. The superotemporal quadrant, at 6 mm from the optic disk, was the most frequent initial site.
CONCLUSIONS
The first retinal neovascularization sites cluster around specific anatomic foci. This information should influence retinopathy monitoring protocols.
目的
研究糖尿病性视网膜新生血管形成的起源部位分布情况。
方法
对3121例患有背景性糖尿病视网膜病变的患者的眼睛进行了研究。这些患者是全身药物治疗实验的志愿者。每年获取彩色立体照片。确定首个视网膜新生血管形成部位，并测量其与视神经的距离。
结果
1年内，282只眼睛出现了新生血管形成。距视盘6毫米处的颞上象限是最常见的起始部位。
结论
首个视网膜新生血管形成部位聚集在特定的解剖学病灶周围。该信息应会影响视网膜病变监测方案。
