摘要

本篇報告計觀察11例視網膜黃斑部分枝靜脈阻塞的病例，其平均追踪時間為12個月。本疾病之最初視力一般都不好，但其長期恢復的能力則未必不好，個體間之差異很大。影響視力恢復的因素主要有（一）中心凹微血管網缺損（二）中心凹出血（三）上枝網膜黃斑靜脈阻塞，以及（四）伴有高血壓性網膜病變等四項。而早期側枝循環之建立，則伴隨著較好的視力預後。若要進行氬氣雷射治療，則我們建議應選擇上枝網膜黃斑靜脈阻塞又伴有黃斑水腫者進行，而不應單獨以黃斑水腫存在與否作選擇標準，因為在我們的觀察中，本病黃斑水腫之發生率高達百分之九十，而其中因為下枝黃斑靜脈阻塞而引起者，其預後良好。

並列摘要

We report 11 cases of macular brach vein occlusion, which constitucle approximately 5.8% of our total branch retinal vein occlusion cases between 1982 and 1987. The mean follow up time is about 12 mouths. The characteristics of this group of disease include: poor initial visual acutiy, variable final visual outcome and prevailing macular edema. Factors that are associated with poor final visual acuity include: (1) Superior macular branch vein involvement. (2) Foveal avascular zone capillary drop-out. (3) Foveal hemorrhage, and, (4) Coexistence of hypertensive retinopathy. Early build-up of collateral circulations always leads to good visual outcome. We do not suggest doing argon laser photo-coagulation to all the cases that have macular edema but still have good visual acuity (≥0.5). We will suggest argon laser photocoagulation in those who have a visual acuity ≥0.05, prominant macular edema and superior macular branch vein involvement, because in our observation, the macular edema in those cases of superior branch vein involvement always deteriorates with time.
