对连续35例获得性免疫缺陷综合征尸检病例的眼睛进行了肉眼、光学和电子显微镜研究,发现了棉絮状斑点(71%的病例),无巨细胞病毒感染区域的视网膜出血(40%),伴有视网膜脱离的巨细胞病毒视网膜炎(34%),罗斯斑(23%),视网膜微动脉瘤(20%),视乳头水肿(14%),结膜卡波西肉瘤(9%)、隐球菌性脉络膜视网膜炎(6%)、视网膜和脉络膜肉芽肿中的细胞内鸟分枝杆菌(6%)、缺血性黄斑病变(6%)、双侧角膜炎(3%)和单纯疱疹性视网膜炎(3%)。本尸检系列中未发现眼部念珠菌感染或弓形虫病。免疫细胞学研究表明免疫球蛋白沉积在小动脉壁,与免疫复合物介导的疾病一致。超微结构研究表明,在棉絮斑点附近的地区血管病变。提出了一种机制,将免疫复合物的沉积与随后的小血管病变、缺血、棉絮斑和后来的巨细胞病毒通过受损的血管内皮扩散到视网膜联系起来。
A gross, light, and electron microscopic study of the eyes from 35 consecutive autopsy cases of the acquired immune deficiency syndrome revealed cotton-wool spots (71% of cases), retinal hemorrhage in areas without cytomegalovirus infection (40%), cytomegalovirus retinitis (34%) with associated retinal detachment, Roth's spots (23%), retinal microaneurysms (20%), papilledema (14%), conjunctival Kaposi's sarcoma (9%), cryptococcal chorioretinitis (6%), Mycobacterium avium-intracellulare in retina and in choroidal granulomas (6%), ischemic maculopathy (6%), bilateral keratitis (3%), and herpes simplex retinitis (3%). Ocular infection with candida or toxoplasmosis were not found in this autopsy series. Immunocytologic studies demonstrated deposition of immunoglobulins in arteriolar walls, consistent with immune complex mediated disease. Ultrastructural studies showed a vasculopathy in the areas near cotton-wool spots. A mechanism is proposed linking the deposition of immune complexes with subsequent small vessel lesions, ischemia, cotton-wool spots and later spread of cytomegalovirus to retina via damaged vascular endothelium.
