Peripapillary Retinitis Pigmentosa Complicated with Bilateral Open-Angle Glaucoma: a Case Report

Although the associations between retinitis pigmentosa (RP) with cataract or chronic angle closure glaucoma have previously been widely recognized, the case of cataract and open-angle glaucoma concurrence in peripapillary RP is rarely reported before. Case presentation: A 65-year-old man complained with progressive visual loss in the right eye for one year. The intraocular pressure (IOP) was 44mmHg in the right eye and 27mmHg in the left eye. Ultrasound biomicroscope (UBM) showed the anterior chamber angle was narrow. Optic disc was expanded in the right eye and 0.6 in the left eye. Fundus revealed pigmentation in posterior polar annularly around the macula, waxy pallor of the disc, attenuated arterioles. The two complications-cataract and optic nerve lesion-may simultaneously lead to progressive visual loss. In RP, open-angle glaucoma may be caused by trabecular meshwork inflammation.
