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 and Methods: 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.

BACKGROUND: A review of pediatric cataract cases operated between January 2003 and March 2005 in the tribal belt of central India was carried out. AIM: We present the profile of cataract cases in children <or=18 years and postoperative visual status in the eyes operated upon. SETTINGS AND DESIGN: This was a retrospective medical record retrieval type of cohort study in a hospital setting. MATERIALS AND METHODS: Pediatric ophthalmologists examined children and operated eyes with cataract. The personal profile, preoperative, intraoperative and postoperative details were noted. The surgical procedures included cataract extraction, intraocular lens implantation, posterior capsulorrhaxis and anterior vitrectomy in most of the cases. We evaluated the visual status of eyes with cataract before and 6 weeks after surgery. STATISTICAL ANALYSIS: We used univariate type of parametric type of statistical analysis. RESULTS: A total of 575 eyes of 502 children had cataract. Cataract in 65 children was bilateral and in 437 cases it was unilateral. Congenital cataracts were in 88 (17.5%) eyes. Traumatic cataracts were noted in 170 (33.9%) eyes. The proportion of cataract was higher in males than in females. Variation in 'number of cataracts' among different age groups was noted. Vision following surgery was more than 6/18 in 84 (16.4%) eyes. The vision could not be assessed in 256 (44%) eyes. CONCLUSION: Improvement of child health care is needed for early detection of cataract in children. Role of rubella and trauma in childhood cataract should be investigated and addressed. Visual assessment and postoperative care should be further improved.
