报告20例孤立性脉络膜血管瘤，此瘤多发生于中壮年男性，常位于眼底后极部，因肿瘤并发的浆液性机网膜脱离而引起视力下降、变视等是患者就诊的主要原因；眼底血管荧光造影早期即呈现网目状荧光，结合眼底所见、超声图像、视野等检查多可确立诊断。对其中15例经光凝固治疗并观察二年以上病例的视力预后与光凝方法、波长特性间的关系进行了初步讨论。 Twenty cases of solitary choroidal hemangiomas were reported. The tumors occurred mostly in middle-aged men and were often located in the posterior pole of the fundus. The loss of vision caused by the detachment of the serous omentum accompanied by tumors was the main reason for patient visits. Fundus fluorescein angiography shows net-like fluorescence at an early stage, and the diagnosis can be established by combining the findings of the fundus, ultrasound images, and visual fields. The relationship between the visual prognosis and the photocoagulation methods and wavelength characteristics of 15 patients who were treated with photocoagulation and observed for more than two years was discussed.
