Vitreous cysts in patients with retinitis pigmentosa. 2015
OBJECTIVE 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.
