ABSTRACT
Aim:
To assess the effectiveness of teachers in a vision screening program for children in classes 5th to 12th attending school in two blocks of a district of north central India. Materials andMethods:
Ophthalmic assistants trained school teachers to measure visual acuity and to identify obvious ocular abnormalities in children. Children with visual acuity worse than 20/30 in any eye and/or any obvious ocular abnormality were referred to an ophthalmic assistant. Ophthalmic assistants also repeated eye examinations on a random sample of children identified as normal (approximately 1%, n=543) by the teachers. Ophthalmic assistants prescribed spectacles to children needing refractive correction and referred children needing further examination to a pediatric ophthalmologist at the base hospital.Results:
Five hundred and thirty teachers from 530 schools enrolled 77,778 children in the project and screened 68,833 (88.50%) of enrolled children. Teachers referred 3,822 children (4.91%) with eye defects for further examination by the ophthalmic assistant who confirmed eye defects in 1242 children (1.80% of all screened children). Myopia (n=410, 33.01%), Vitamin A deficiency (n=143, 11.51%) and strabismus (n=134, 10.79%) were the most common eye problems identified by the ophthalmic assistant. Ophthalmic assistants identified 57.97% referrals as false positives and 6.08% children as false negatives from the random sample of normal children. Spectacles were prescribed to 39.47% of children confirmed with eye defects.Conclusions:
Primary vision screening by teachers has effectively reduced the workload of ophthalmic assistants. High false positive and false negative rates need to be studied further.
