This 31YOF with a known history of retinitis pigmentosa (RP) presented with 2 days of decreased vision OD. There was a history of trauma to her right eye at 2 years of age. Vision was counting fingers OD and 20/120 OS. Slit lamp examination OD revealed a non-central corneal scar and anterior synechia consistent with the prior trauma.
MultiColor imaging shows bilateral RP intraretinal pigment migration and narrowed arterioles. A free-floating vitreous cyst is noted OD inferiorly.
Learning Points:
Vitreous cysts are extremely rare, idiopathic, and usually diagnosed incidentally. Likely originating from a ciliary body cyst (Dhull et al, Ophthalmology Retina 2020;4:1208), they can be either congenital or acquired. Acquired cysts have been associated with numerous ocular disorders, including trauma and retinitis pigmentosa, as in our patient.
