Abstract
Background: Worldwide there are nearly 2.7 million blind people due to corneal disease which is a major causes of blindness in the world today and remains second only to cataract. Aim & Objective: The present hospital based retrospective study was undertaken to estimate the prevalence of corneal blindness in patients attending tertiary eye care center in Chalmeda Anand Rao Institute of Medical Sciences, Karimnagar. Material and Methods: A hospital based study was conducted over a period of 1 year from August 2014 to August 2015. Participants were patients attending outpatient department of Chalmeda Anand Rao Institute of Medical Sciences. Detailed history was taken and comprehensive ocular examination including Snellens E-chart for visual acuity, slit lamp bio microscopy, contact tonometry, posterior segment evaluation through B-scan and dilated retinal evaluation when indicated was performed at outpatient department. Results: Overall, 33,566 patients were examined. Proportion of corneal blindness was 3.9% (CI-95% 3.6% - 4.3%). The proportion increased with age in elderly patients (5.7%) and was higher among the females (5.2%) compared to males (2.8%). The most common cause of corneal blindness in our study was ocular trauma which was 59.5%. Conclusion: The study ?ndings demonstrate that currently ocular trauma, corneal ulceration, infectious keratitis, postsurgical bullous keratopathy, and corneal degenerations are responsible for the major burden of corneal blindness among the patients attending outpatient department.
