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.
在一名49岁患者的右眼眼底观察到沿视网膜静脉的脉络膜视网膜萎缩伴色素沉着。左眼观察到广泛的视网膜色素变性(RP)。动态定量视野测试显示右眼有一个与视网膜脉络膜萎缩区域相对应的暗点,左眼观察到传入性视野缩窄。视网膜电图测试显示右眼为衰减型,左眼为阴性型。因此,他的右眼和左眼情况分别被诊断为色素性静脉旁视网膜脉络膜萎缩(PPRCA)和RP。因此,单侧RP的PPRCA患者比例可能比预期的更高。
