To report a recently observed association of macular vitelliform detachment and subretinal drusenoid deposits (reticular pseudodrusen).
Clinical and multimodal imaging data of patients with acquired vitelliform lesions in association with subretinal drusenoid deposits were reviewed. Acquired vitelliform lesions were defined as subretinal accumulations of yellow material that developed in adulthood. Subretinal drusenoid deposits were diagnosed as being present if there were drusen-like accumulations that colocalized with aggregates of subretinal material as seen by multimodal imaging including spectral-domain optical coherence tomography, autofluorescence, and near-infrared imaging.
Seven eyes of 6 patients with a mean age of 85 years, all of whom were white, were found to have vitelliform material in association with subretinal drusenoid deposits. The median visual acuity was 20/30. The vitelliform material was hyperautofluorescent and was in all eyes located in the subretinal space between the inner segment/outer segment junction and the retinal pigment epithelium. This material had the same color, autofluorescence, and optical coherence tomographic characteristics as the vitelliform material seen in association with cuticular drusen.
Acquired vitelliform lesions can occur in association with subretinal drusenoid deposits. Subretinal drusenoid deposits might be mistaken for cuticular drusen because of their similar appearance in color fundus photography but can be easily distinguished with multimodal imaging because they lie above the retinal pigment epithelium. Subretinal drusenoid deposits may reflect abnormalities in the function of the retinal pigment epithelium and their presence may interfere with photoreceptor outer segment turnover, leading to an accumulation of vitelliform material.
报告最近观察到的黄斑部玻璃膜疣样脱离与视网膜下类 drusen 样沉积物(网状假性 drusen)之间的关联。
回顾了与视网膜下类 drusen 样沉积物相关的获得性玻璃膜疣病变患者的临床和多模态成像数据。获得性玻璃膜疣病变定义为成年后出现的视网膜下黄色物质积聚。如果存在与多模态成像(包括频域光相干断层扫描、自发荧光和近红外成像)所见的视网膜下物质聚集共定位的 drusen 样积聚,则诊断为视网膜下类 drusen 样沉积物。
发现 6 名患者的 7 只眼存在与视网膜下类 drusen 样沉积物相关的玻璃膜疣样物质,这些患者的平均年龄为 85 岁,均为白人。中位视力为 20/30。玻璃膜疣样物质呈高自发荧光,在所有眼中均位于内节/外节交界处和视网膜色素上皮之间的视网膜下空间。该物质的颜色、自发荧光和光相干断层扫描特征与与角膜 drusen 相关的玻璃膜疣样物质相同。
获得性玻璃膜疣病变可与视网膜下类 drusen 样沉积物相关发生。由于它们在眼底彩色照片中的外观相似,视网膜下类 drusen 样沉积物可能会被误认为是角膜 drusen,但可以通过多模态成像轻松区分,因为它们位于视网膜色素上皮上方。视网膜下类 drusen 样沉积物可能反映了视网膜色素上皮功能的异常,其存在可能干扰光感受器外节的更替,导致玻璃膜疣样物质的积聚。
