Coexistence of posterior staphyloma, retinitis pigmentosa and moderate myopia

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

prevalence and causes of visual impairment in young Turkish men

To explore the causes and prevalence of visual impairment in young Turkish men. The health examination data of the candidates that are saved in National Defense Ministry of Turkey was used. The data of the candidates examined between 1 January 2009 and 31 December 2011 were evaluated. The total number of the candidates was 1777500. The candidates requiring advanced examination are referred to secondary and tertiary examination hospitals. Fourteen thousand eight hundred sixty two[14862] out of 1777500 candidates were declared unfit for compulsory military service because of ophthalmic causes. The prevalence of ophthalmologic diseases causing unfitness for military service was found 0.746% for 2009, 0.871% for 2010 and 0.889% for 2011. These included high refractive errors which was the most frequent pathology causing unfitness [40.1%]. Nonsurgical retina, vitreous and optic nerve diseases were the most frequent cause of visual impairment [0.212%]. Corneal and lens pathologies were the second most frequent cause of blindness [0.101%]. The data bank in National Defense Ministry analyzed in this study is not directly intended to explore the causes and prevalence of visual impairment in Turkey. However this study gives considerable knowledge about the causes and prevalence of visual impairment in Turkey
