Summary: | 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 Snellen 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 out patient
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 ?findings 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. |
