Abstract：
Chorioretinal atrophy with pigmentation along the retinal veins was observed in the right fundus of a 49-year-old patient. Extensive retinitis pigmentosa (RP) was observed in the left eye. Dynamic quantitative visual field testing revealed a scotoma in the right eye that corresponded to the area of retinochoroidal atrophy and afferent visual field constriction was observed on the left eye. An electroretinogram test revealed that the right eye showed attenuated type and the left eye showed negative type. Thus, the conditions of his right eye and left eye were diagnosed as pigmented paravenous retinochoroidal atrophy (PPRCA) and RP, respectively. Thus, there may be a higher proportion of PPRCA patients with unilateral RP than expected.
摘要：
在49岁患者的右眼底观察到脉络膜视网膜萎缩，沿视网膜静脉有色素沉着。在左眼中观察到广泛的色素性视网膜炎（RP）。动态定量视野测试显示右眼暗点对应于视网膜脉络膜萎缩区域，左眼观察到传入视野收缩。视网膜电图测试显示，右眼显示衰减型，左眼显示阴性型。因此，他的右眼和左眼的情况被诊断为色素性静脉脉络膜萎缩（PPRCA）和RP，分别。因此，PPRCA患者单侧RP的比例可能高于预期.
