PURPOSE
To describe a patient with retinal complications of essential thrombocytosis.
METHOD
Case report. A 24-year-old man with acute vitreous hemorrhage of the right eye underwent ocular and systemic examinations to elucidate the origin of this condition.
RESULTS
Fluorescein angiography of the right eye showed an avascular peripheral retina with marked capillary nonperfusion, arteriovenous anastomosis, and sea fan neovascularization. Blood studies showed thrombocytosis without other associated systemic diseases. The peripheral retinal capillary nonperfusion and sea fan neovascularization were treated with dye-laser photocoagulation, and aspirin, 80 mg daily, was given for systemic treatment.
CONCLUSIONS
In our patient, the avascular retina was associated with essential thrombocytosis, which may cause an avascular peripheral retina with neovascularization and vitreous hemorrhage in otherwise healthy persons.
目的
描述一名原发性血小板增多症视网膜并发症患者。
方法
病例报告。一名右眼急性玻璃体积血的24岁男性接受了眼科及全身检查以明确病因。
结果
右眼荧光素血管造影显示周边视网膜无血管，伴有明显的毛细血管无灌注、动静脉吻合及海扇状新生血管形成。血液检查显示血小板增多，无其他相关全身性疾病。对周边视网膜毛细血管无灌注及海扇状新生血管进行了染料激光光凝治疗，并给予每日80毫克阿司匹林进行全身治疗。
结论
在我们的患者中，无血管视网膜与原发性血小板增多症相关，这可能在其他方面健康的个体中导致周边无血管视网膜伴新生血管形成及玻璃体积血。
