Pigment dispersion syndrome (PDS) can have varied manifestations. Anterior and posterior segment involvement by dispersed pigments was documented in gross pathology and by staining under microscopy. Pigmentary changes in the sclera, cornea, anterior chamber, iris, trabecular meshwork, lens, and retinal pigment epithelium and optic nerve findings were consistent with PDS. External scleral and vitreous pigmentation has never been reported before in the scientific literature. Retinal pigment degeneration and granule dispersion were seen throughout the retina which could be a contributing factor in the etiology of PDS.
Intraocular crystals are seen in chronic uveitis. We present a case of a young man with clinical presentation of refractile crystals in the anterior chamber (AC) with right painful blind eye secondary to uveitic glaucoma, which had earlier retinal detachment surgery. AC tap revealed the crystals in cytology, and further, enucleation of the eyeball showed those crystals in the anterior and posterior segments of the eye. Intraocular crystals at multiple sites were rare occurrence.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
