Abstract :

Background : To study optic atrophy as a cause of blindness in patients attending regional eye hospital,Kurnool for blind certificate. Methods : A total of 370 patients of all age groups attending to Regional Eye Hospital, Kurnool for blind certificate during the period June 2015 to June 2016 were examined. Examination included visual acuity testing using Snellen chart, refraction,colour vision and contrast vision,slitlamp biomicroscopy, intra ocular pressure measurement using Goldman Applanation Tonometer, fundus examination with indirect ophthalmoscope, visual field testing using Humphry field analyser. Fundus picture was taken using Zeiss fundus camera. Patients with optic nerve involvement were exclusively included in the study. Results :Of these 370 patients, 55 patients had optic atrophy. Of these 55 patients, 18 had primary optic atrophy, 10 had secondary optic atrophy, 27 had consecutive optic atrophy. Among these 27 patients with consecutive optic atrophy, 18 had associated retinitis pigmentosa, 9 had associated choroiditis. Conclusion :optic atrophy is one of the cause of blindness that developed either due to idiopathic cause or secondarily due to post papilloedema or papillitis. It may also be associated with retinitis pigmentosa or choroiditis.
