A 66-year-old male patient presented with decreased vision in both eyes following episode of Chikungunya fever. Examination revealed bilateral retinal lesions with stippled pigmentary changes at the level of the choriocapillaris, involving the macula in the left eye. The retinopathy consisted of outer retinal disruption and retinochoroidal flow abnormalities detected using with additional imaging, including spectral-domain optical coherence tomography (OCT), autofluorescence, and OCT angiography (OCTA). The index case report describes unique OCTA findings in both eyes of an elderly male secondary to Chikungunya fever. Using the technique of OCTA, insights into the mechanisms of visual damage in viral retinopathies such as Chikungunya fever can be understood.
一名66岁男性患者在基孔肯雅热发作后出现双眼视力下降。检查发现双侧视网膜病变，在脉络膜毛细血管层有散在的色素沉着改变，左眼累及黄斑。视网膜病变包括外层视网膜破坏和视网膜脉络膜血流异常，通过额外的成像检查发现，包括光谱域光学相干断层扫描（OCT）、自发荧光和OCT血管造影（OCTA）。该病例报告描述了一名老年男性继发于基孔肯雅热后双眼独特的OCTA表现。利用OCTA技术，可以了解基孔肯雅热等病毒性视网膜病变中视觉损伤的机制。
