Fifty patients who developed preretinal or papillary neovascularization following tributary vein occlusion were treated by laser photocoagulation. Areas of non-perfused retina within the distribution of the obstructed vein were identified by fluorescein angiography and ablated using moderately intense laser photocoagulation burns. In forty-six patients there was satisfactory atrophy of both preretinal and papillary neovascularization without further complication or vitreous haemorrhage. Four patients who responded poorly to laser photocoagulation did so either because areas of ischaemic retina were inadequately treated or because they were unamenable to laser photocoagulation e.g., sited in the parafoveal region. Ablation of ischaemic perimacular retina together with associated intraretinal microvascular abnormalities aided the resolution of macular oedema in 19 patients. No post-operative complications could be attributed to laser photocoagulation excepting the development of fine perimacular retinal folds in one patient.
50例分支静脉阻塞后发生视网膜前或视乳头新生血管的患者接受了激光光凝治疗。通过荧光素血管造影确定阻塞静脉分布范围内无灌注视网膜区域，并使用中等强度的激光光凝烧伤进行消融。46例患者视网膜前和视乳头新生血管均出现满意的萎缩，未发生进一步并发症或玻璃体出血。4例对激光光凝反应不佳的患者，原因要么是缺血性视网膜区域治疗不充分，要么是不适合激光光凝，例如位于黄斑旁区域。19例患者通过消融缺血性黄斑周围视网膜及相关视网膜内微血管异常，有助于黄斑水肿的消退。除1例患者出现黄斑周围细小视网膜皱褶外，无术后并发症可归因于激光光凝。
