Door-to-door Screening as a New Model Augmenting School Eye Screening: Reaching Out to School Age Children in the Midst of a Pandemic

ABSTRACT

Purpose

Explore door-to-door eye screening in India as a model to reach school age children in need of eye care, especially during school closures due to the Covid-19 pandemic.

Methods

Children between 5 and 18 years were screened in an urban-slum of Delhi from September 2020 to March 2021. Screening included capturing ocular complaints, visual acuity and conducting a torchlight examination. Children with any eye-related complaints, gross abnormality or a LogMAR acuity of more than 0.2 in either eye were referred to the nearby vision centre. Data were disaggregated by gender and age group. Reporting after referral and proportion of true positives referrals were used to assess the model.

Results

32,857 children were screened. 55% were boys. Only 917 children (2.8%) had previous eye examinations. 1814 (5.5%) children were referred. Overall compliance rate amongst those referred was 59% (1070 of 1814) and compliance was significantly higher (72%) amongst those referred with poor vision as compared to those with only ocular morbidities (38%). Overall compliance was significantly higher amongst older age group (64% vs 50%) and amongst girls than boys (61% vs 56%). 3.9% children were detected with refractive error (RE) and 2.5% with uncorrected RE which was significantly higher in girls and in older age group. Of 1070 children reporting after referral, 85% had confirmed diagnosis for RE or other ocular pathology.

Conclusion

Door-to-door screening had good referral compliance and positive predictive value. We recommend this model as a supplement to school screening especially in regions with low enrolment and high absenteeism in schools.
