The purpose of this study was to report a 30-year-old woman with Eales disease, showing bilateral proliferative tissue. The retinal vessels were evaluated using widefield optical coherence tomography angiography (widefield OCTA), which has a wider angle of view compared with conventional instruments.
This is a case report.
Widefield OCTA showed an extensive nonperfusion area and A-V shunt in both eyes and a vascular structure in the left eye that appeared to be retinal neovascularization. Ultra-widefield fluorescein angiography revealed no filling delay in the early phase, a vast nonperfusion area from the midperiphery to the ora serrata in bilateral eyes, and retinal neovascularization in the left eye. Based on the results of ultra-widefield angiography, OCTA examination, and systemic examination, a diagnosis of Eales disease was finally made after all the differential diseases had been excluded.
In a patient with Eales disease, the peripheral nonperfusion area and retinal neovascularization that were consistent with the ultra-widefield angiography findings were noninvasively confirmed by widefield OCTA. Widefield OCTA is useful in the detection of peripheral changes of the fundus.
本研究旨在报告一名患有伊尔斯病的30岁女性，其双眼出现增生性组织。使用广角光学相干断层扫描血管造影（广角OCTA）对视网膜血管进行评估，该技术与传统仪器相比具有更宽的视角。
这是一例病例报告。
广角OCTA显示双眼均有广泛的无灌注区和动静脉分流，左眼有一个似乎是视网膜新生血管的血管结构。超广角荧光素血管造影显示早期无充盈延迟，双眼从周边中部到锯齿缘有大片无灌注区，左眼有视网膜新生血管。根据超广角血管造影、OCTA检查和全身检查结果，在排除所有鉴别疾病后最终确诊为伊尔斯病。
在伊尔斯病患者中，广角OCTA无创性地证实了与超广角血管造影结果一致的周边无灌注区和视网膜新生血管。广角OCTA有助于检测眼底的周边变化。
