Idiopathic macular telangiectasia type 2 (MacTel 2) is a slow and progressive bilateral condition that affects middle-aged and elderly individuals. Vision loss is generally mild and occurs over the course of many years. The development of sub-retinal neovascularisation (SRNV) can occur late in the disease process, and lead to more dramatic vision loss. A report is presented of 2cases of MacTel 2 in which optical coherence tomography angiography (OCTA) was essential for the diagnosis of secondary SRNV. The commercially available OCTA Cirrus AngioPlex 5000 platform (Zeiss, Jena, Germany) was used. Subretinal neovascularization was detectable in both cases in OCTA at the level of the deep capillary plexus and the avascular layer. OCTA also allowed us to monitor disease progression and monitor response to anti-VEGF therapy.
2型特发性黄斑毛细血管扩张症（MacTel 2）是一种缓慢进展的双侧性疾病，影响中老年人。视力丧失通常较轻，且在多年病程中逐渐发生。视网膜下新生血管形成（SRNV）可在疾病后期出现，并导致更显著的视力丧失。本文报告了2例MacTel 2病例，其中光学相干断层扫描血管造影（OCTA）对继发性SRNV的诊断至关重要。使用了市售的OCTA Cirrus AngioPlex 5000平台（德国耶拿蔡司公司）。在OCTA检查中，两例患者在深层毛细血管丛和无血管层水平均检测到视网膜下新生血管。OCTA还使我们能够监测疾病进展并监测抗VEGF治疗的反应。
