To report the presentation and management of active iris vascular tuft (IVT) hemorrhage and spontaneous hyphema in an eye with previous branch retinal vein occlusion (BRVO).
A 74-year-old male with a history of BRVO in the left eye presented with spontaneous hyphema and blurred vision. Clinical examination confirmed the presence of an actively bleeding IVT at the pupillary margin in the left eye. Sustained hemostasis was achieved following intravitreal bevacizumab injection and pressure patching of the eye.
This is the first case report to demonstrate pressure patching as a non-invasive, effective method of achieving hemostasis in the acute setting of IVT hemorrhage. Intravitreal vascular endothelial growth factor antagonists such as bevacizumab may also be useful in decreasing the risk of IVT hemorrhage in eyes with chronic ischemia, although further investigation is warranted.
报告既往有视网膜分支静脉阻塞（BRVO）的眼内活动性虹膜血管簇（IVT）出血和自发性前房积血的表现及处理。
一名74岁男性，左眼有BRVO病史，出现自发性前房积血和视力模糊。临床检查证实左眼瞳孔边缘存在活动性出血的IVT。玻璃体腔内注射贝伐单抗并对眼睛进行加压包扎后实现了持续止血。
这是首例证明加压包扎作为IVT出血急性期实现止血的非侵入性有效方法的病例报告。玻璃体腔内血管内皮生长因子拮抗剂如贝伐单抗在降低慢性缺血性眼病IVT出血风险方面可能也有用，尽管仍需进一步研究。
