Nonpigmented immobile large vitreous cyst: A rare case report

Abstract

Primary vitreous cysts are rare ocular manifestations. Often, they do not cause any visual disturbances. Vitreous cysts can be congenital or acquired. Here, we report the case of a 60-year-old male patient who presented to our outpatient department with a complaint of a bubble-like floater in his right eye which remained fixed despite movement of eyeballs. He had this visual disturbance for the past 20 years. The size and appearance of floater remained constant all these years. Aided visual acuity was 20/20 in both the eyes. Fundus examination showed the presence of a single transparent nonmobile cyst in the vitreous cavity of the right eye. Left eye fundus was normal. Right eye B-scan showed a nonmobile vitreous cyst abutting the optic nerve. The patient tested negative for Echinococcus and cysticercosis. As it was a primary vitreous cyst and the patient was asymptomatic, we decided to keep the patient under regular follow-up.
