Preretinal deposits (PDs) are a rare condition among fundus diseases. We found that preretinal deposits have some features in common that can provide clinical information. This review affords an overview of PDs in different but related ocular diseases and events, and summarizes the clinical features and possible origin of PDs in related conditions, providing diagnostic clues for ophthalmologists when facing PDs. A literature search was performed using three major electronic databases (PubMed, EMBASE, and Google Scholar) to identify potentially relevant articles published on or before June 4, 2022. Most of the cases in the enrolled articles had optical coherence tomography (OCT) images to confirm the preretinal location of the deposits. Thirty-two publications reported PD-related conditions, including ocular toxoplasmosis (OT), syphilitic uveitis, vitreoretinal lymphoma, human T-cell lymphotropic virus type 1 (HTLV-I) associated uveitis or HTLV-I carriers, acute retinal necrosis, endogenous fungal endophthalmitis, idiopathic uveitis, and exogenous materials. Based on our review, OT is the most frequent infectious disease to exhibit PDs, and silicone oil tamponade is the most common exogenous cause of preretinal deposits. PDs in inflammatory diseases are highly suggestive of active infectious disease and are preferentially accompanied by a retinitis area. However, PDs will largely resolve after etiological treatment in either inflammatory or exogenous conditions.
