Abstract
A 32-year-old white man developed distinctive episcleral and conjunctival pigmentation surrounding a sclerotomy site 6 weeks after vitrectomy and retinal reattachment surgery. The conjunctival lesion was biopsied during a second operation to remove an epiretinal membrane causing macular pucker. Light and electron microscopic studies demonstrated melanin granules extracellularly and within macrophages.
摘要
一名32岁白人男性在玻璃体切除术和视网膜复位手术后6周，在巩膜切开部位周围出现了独特的巩膜表层和结膜色素沉着。在第二次手术中对结膜病变进行活检，以切除引起黄斑皱褶的视网膜前膜。光镜和电镜研究显示，黑色素颗粒存在于细胞外和巨噬细胞内。
