Childhood blindness in a rural population of southern India: prevalence and etiology

publication date

Abstract/Introduction

Purpose: To determine the prevalence and etiology of childhood blindness in a rural population in southern India through a population based study.

Methods: A cross sectional, house-to-house survey to screen for childhood blindness included 14,423 children < 16 years. Blindness was defined as best corrected visual acuity < 3/60 in the better eye. The first stage of screening for blindness was done by interns under supervision of ophthalmology residents. Senior residents examined the referred cases from the first stage. Those detected to be blind were brought to a tertiary care hospital for detailed examination.

Conclusion/Results

Results: Fifty-four children were referred after first stage of screening of 13,241 children. Of these 14 were bilaterally blind giving a prevalence of 1.06/1000 (95% confidence interval (CI), 0.50 to 1.61); 6 (42.9%) had lens and related complications, 4 (28.6%) had globe anomalies (2 Microphthalmos and 2 Anophthalmos), 2 (14.3%) had retinal dystrophy and 1 (7.1%) each of glaucoma and optic atrophy. Among the parents of blind children, 71.4% (p = 0.002) had consanguineous marriage (83.3% in cataract blind children).

Conclusions: More than half of the blindness detected was potentially avoidable. Genetic counseling, early identification and access to tertiary care would reduce the burden of childhood blindness in the local community.

Testimonials

At Amplify with Dr Wernick I was seeking help for seemingly intractable, probably age-related dryness. I've seen other doctors about it, and that has been helpful, but what he explained to me about it and the careful way he answered all my questions gave me so much more of a clear understanding of what is going on (and is not) that I am more able to implement all his and others' recommendations than I was before. And he gave me additional resources for further follow-up. I am most grateful.

Wow! This is a great Eye Care medical facility. I was thoroughly examined by Dr. Pinkhasov for over 2 hours. She made sure to check my eyes for pretty much everything and patiently explained proper care for my eyes. They definitely know how to provide great care and treat their patients right. Now I know why they have such a great reputation and been around for so long.

Dr. Kavner is a gifted diagnostician and orthoptic therapist. He treated me several decades ago for a condition similar to dyslexia. I was having migraines five times per week. I worked with him for about a year and I experienced tremendous improvement (down to 3-4 per year) that has lasted.

Dr. Kavner recommended two types of eye therapy for my daughter. One of them using bio-feedback. In just three sessions she is seeing considerably better. She shouted this morning: Ooh my God! I could not see these letters with my glasses on, and now I can see them without my glasses. If you are willing and able to invest in improving your vision, this is a good place to go to!
