To report findings of pigmented anterior corneal deposits in a human immunodeficiency virus-positive patient.
Case report. A 49-year-old human immunodeficiency virus-positive patient was examined after the appearance of pigmented corneal deposits. Slit-lamp biomicroscopy, fundus photography, and laser-scanning in vivo confocal microscopy were performed to visually document the ocular condition.
The patient had a history of Mycobacterium avium infection and was suspected to have recovery uveitis from a cytomegalovirus infection. Small, rounded, light brown-colored deposits were distributed across the anterior cornea from limbus to limbus, bilaterally. In vivo confocal microscopy revealed the deposits to be confined to the basal epithelium and Bowman layer, whereas the posterior stroma, Descemet membrane, and the endothelium appeared normal. Systemic steroid treatment was administered, and 2 weeks later, the deposits had vanished on slit-lamp examination, whereas remnants were observed at the microscopic level.
The deposits were unusual for their anterior corneal location and pancorneal distribution. The response to systemic steroid treatment remains unexplained and illustrates the complexity of the underlying conditions, their treatment, and the associated pathways of ocular manifestation.
报告一名人类免疫缺陷病毒(HIV)阳性患者出现前角膜色素沉着的发现。
病例报告。对出现色素性角膜沉积物的 49 岁 HIV 阳性患者进行了检查。进行了裂隙灯生物显微镜检查、眼底照相和激光共聚焦显微镜检查,以直观记录眼部状况。
该患者有鸟分枝杆菌感染史,疑似巨细胞病毒感染后恢复性虹膜炎。双侧从前缘到后缘的角膜均有小而圆的浅棕色沉积物。体内共聚焦显微镜显示沉积物局限于基底层上皮和Bowman 层,而后基质、Descemet 膜和内皮正常。给予全身类固醇治疗,2 周后,裂隙灯检查发现沉积物消失,而在显微镜下仍可见残留物。
这些沉积物以前角膜位置和全角膜分布为特点,不同寻常。对全身类固醇治疗的反应尚不清楚,说明了潜在疾病、治疗及其相关眼部表现途径的复杂性。
