To investigate the morphological features of keratic precipitates (KPs) with in vivo confocal microscopy (IVCM) in vitreoretinal lymphoma (VRL).Patients with biopsy-proven VRL were reviewed, and 12 patients (16 eyes) with KPs examined by IVCM were included.Five distinct KP morphologies on IVCM were observed: dendritic, nibbling, linear, globular, and stippled. Dendritic KPs were discovered in 9 eyes (56.3%), with a hyperreflective core and multiple thin pseudopodia. Nibbling KPs were found in 8 eyes (50.0%), featuring irregularly hyperreflective borders and a mottled reflective interior. Linear, stippled, and globular KPs were self-explanatory and affected nearly all eyes. Globular KPs seem to be formed by hyperreflective cells with large nuclei and prominent nucleoli, similar to atypical lymphocytes in vitreous cytology.IVCM could provide more insight into the morphological traits of KPs than clinical observation, highlighting its potential for identifying VRL involving the anterior segment.
