This healthy 20YO female presented with chronic floaters in her left eye. Vision was 20/20 in her healthy OD and 20/20 OS.
Funduscopy shows a large pigmented vitreous cyst floating over the superior macula. Observation was recommended.
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.
