PURPOSE: To determine the prevalence of vitreous cysts in patients with retinitis pigmentosa (RP). METHODS: We retrospectively reviewed the charts of 435 consecutive patients diagnosed as having typical RP. RESULTS: Vitreous cysts were diagnosed in 37 eyes of 28 patients with RP (13 males and 15 females; mean age 47.0 ± 19.8 years; range 15-79 years), for an overall prevalence of 6.4%. The cysts were observed bilaterally in nine of the patients (32.1%). Among these 28 patients, 11 (39.3%) were younger than 40 years. In all, 81.8% of the vitreous cysts were detected around the optic nerve head. CONCLUSIONS: We demonstrated that the prevalence of vitreous cysts was 6.4% in patients with RP. These cysts were considered to be asymptomatic.
