title: Coexistence of Posterior Staphyloma, Retinitis Pigmentosa and Moderate Myopia.
abstract: The authors report a 22-year patient presented with night-blindness and progressive visual loss. Ophthalmologic examination included slit lamp biomicroscopy, best-corrected distance visual acuity, cycloplegic refraction, A-mode and B-mode ultrasonography, and full-field flash electroretinogram (ERG). Cycloplegic refractions were -6.00 (-1.25 x 175) dpt in the right eye and -7.00 (-1.50 x 165) dpt in the left eye. Slit lamp examination showed normal anterior segment. Fundoscopic examination revealed bone-spicule pigmentations, waxy optic disc, arteriolar narrowing and posterior staphyloma, with 5 optic disc in diameter in the right eye and 4 optic disc diameter in the left. Ocular ultrasonography confirmed staphyloma. Full-field ERG showed evidence of a generalized retinal dysfunction involving both rod and cone responses, supported the diagnosis of retinitis pigmentosa.
