Abstract:  Objective To study the clinical characteristics of glaucoma associated with retinitis pigmentosa (RP). Design Retrospective case series. Participants 37 patients (62 eyes) of RP associated with glaucoma and 109 patients (215 eyes) of RP without glaucoma were evaluated in Beijing Tongren Hospital from Aug. 2008 to Sep. 2012. Methods The clinical electronic records and medical records of the participants were reviewed. Main Outcome Measures The classification of glaucoma, corrected visual acuity and intraocular pressure(IOP). Results In 37 patients（62 eyes）of glaucoma associated with RP, there were 9 cases (18 eyes, 29.0%) with acute angle closure glaucoma, 21 cases (34 eyes, 54.8%) with chronic angle closure glaucoma and 7 cases (10 eyes, 16.1%) with primary open angle glaucoma. The percentage of visual acuity below 0.05 of RP with glaucoma and without glaucoma was 58.9% and 33.6%, respectively (P=0.000). The mean IOP of glaucoma with RP was 23.1±14.0 mm Hg. Conclusion In this retrospective case series, RP was associated with primary angle closure glaucoma much frenquently than with primary open angle glaucoma, and their visual impairment was more serious.
