Retinal cavernous hemangioma is a rare congenital vascular malformation with typical fundus changes. Optical coherence tomography angiography (OCTA), which is in rise in the recent years, is a rapid and noninvasive technology to assist in obtaining information regarding the blood flow changes in the fundus lesions from different layers without injecting a contrast agent.
A 40-year-old male patient with visual occlusion in the right eye for >1 month was reported.
Retinal cavernous hemangioma was diagnosed by fundus examination, fluorescein angiography (FA) and OCTA, and the characteristics of OCTA images were analyzed.
The lesion occurred outside the macula, the central vision remained basically normal, and no significant complications were noted in this patient. Therefore, we preferred to regularly follow-up without therapeutic intervention.
OCTA can display fundus blood flow and vascular lesions noninvasively and rapidly. On OCTA, retinal cavernous hemangiomas showed characteristic changes and have good correspondence with fundus imaging and FA examinations. Moreover, OCTA remains more sensitive to vascular abnormalities, and imaging remains clearer, providing new diagnosis and follow-up route for this disease.
视网膜海绵状血管瘤是一种罕见的先天性血管畸形，具有典型的眼底改变。光学相干断层扫描血管造影（OCTA）是近年来兴起的一项快速、无创技术，无需注射造影剂即可协助获取眼底病变不同层次血流变化的信息。
报告了一名40岁男性患者，右眼视力遮挡超过1个月。
通过眼底检查、荧光素血管造影（FA）和OCTA诊断为视网膜海绵状血管瘤，并分析了OCTA图像的特征。
病变位于黄斑以外，中心视力基本正常，该患者未发现明显并发症。因此，我们选择定期随访，不进行治疗干预。
OCTA能够快速、无创地显示眼底血流和血管病变。在OCTA上，视网膜海绵状血管瘤表现出特征性改变，与眼底成像和FA检查具有良好的一致性。此外，OCTA对血管异常更为敏感，成像更清晰，为该病提供了新的诊断和随访途径。
