Atypical retinitis pigmentosa masquerading as primary open-angle glaucoma
Lin J -C; Vander JF; Martin M; Katz JJournal of Glaucoma 2007; 16: 268-270
PURPOSE: This study was conducted to describe a case of atypical retinitis pigmentosa initially diagnosed with primary open angle glaucoma. METHODS: Complete ophthalmologic examination, visual field examination, electroretinogram, and Heidelberg Retinal Tomograph were performed. RESULTS: Visual field examination showed arcuate defects extending to large temporal defects OU. Electroretinogram showed significant abnormalities with reduced b wave amplitudes and prolonged implicit times. Heidelberg Retinal Tomograph revealed a small central cup with no neuroretinal rim thinning or nerve fiber layer dropout OU. CONCLUSIONS: The present report suggests that visual field defects atypical for glaucoma should be carefully scrutinized for other etiologies.
