To describe the course of posterior subhyaloid precipitates (PSPs) accompanying active retinitis. : Retrospective study of three retinitis cases associated with PSPs and literature review. : Cases 1 and 2 were Toxoplasma retinochoroiditis. Case 3 had bilateral retinitis post-febrile illness. PSPs were yellowish-white spherical lesions seen in the presence of partial posterior hyaloid detachment (PVD) in the retro-hyaloid space lining the inferior PVD margin. In all 3 cases, PSPs resolved during treatment for primary disease. Resolution of PSPs preceded resolution of retinitis. Literature review revealed similar lesions in CMV retinitis and syphilis in addition to Toxoplasma retinochoroiditis. : PSPs were seen in the presence of active retinitis and partial PVD when inflammatory aggregates gravitate inferiorly in the subhyaloid space. They were observed during active retinitis and their resolution preceded the resolution of retinitis, thus providing a potential marker for disease resolution.
描述伴有活动性视网膜炎的后玻璃体液下沉淀物 (PSP) 的病程。：与 PSP 相关的三例视网膜炎病例的回顾性研究及文献复习。：病例 1 和 2 为弓形虫性视网膜炎脉络膜炎。病例 3 为发热后双侧视网膜炎。PSP 为黄白色球形病变，见于后玻璃体液下方的后玻璃体液分离 (PVD) 存在时，位于后下方 PVD 边缘的后玻璃体液空间。在所有 3 例中，PSP 在原发性疾病治疗过程中得到解决。PSP 的解决先于视网膜炎的解决。文献复习还发现 CMV 视网膜炎和梅毒中也有类似的病变，除了弓形虫性视网膜炎脉络膜炎。：当炎症聚集体在玻璃体液下空间中向下方移动时，PSP 出现在活动性视网膜炎和部分 PVD 的存在下。它们在活动性视网膜炎期间被观察到，其解决先于视网膜炎的解决，因此为疾病解决提供了一个潜在的标志物。
