点状内层脉络膜病变一例
|
Abstract:
点状内层脉络膜病变(punctate inner choroidopathy, PIC)是一类较罕见的眼底疾病，包括脉络膜内层和视网膜色素上皮层(retina pigment epithelium, RPE)。它在年轻的近视女性中更常见，患者主要表现为视力下降、眼睛前黑点和视物变形。它的特征是在视网膜色素上皮和脉络膜内层出现散发性类圆形的黄白色病灶，眼前节和玻璃体无炎症。脉络膜新生血管(choroid neovascularization, CNV)形成的主要原因也是本病视力丧失的主要原因。早期发现、早期治疗PIC继发性CNV，对于患者视力的保护极其重要。
The punctate inner choroidopathy (PIC) is a rare fundus disease. The lesion consists of the inner choroid and retina pigment epithelium (RPE). It is more common in young women with myopia, with reduced vision, dark spots in front of the eye and distorted vision. It is characterized by sporadic round yellowish-white lesions in the retinal pigment epithelium and choroid inner layer, without inflammation in anterior segment and vitreous. Choroid neovascularization (CNV) is the main cause of vision loss in this disease. Early detection and early treatment of PIC secondary CNV are extremely important for visual protection of patients.
