To estimate the prevalence of ocular morbidity and impact of digital display devices among school children attending Air Force school in Delhi. This was a descriptive cross-sectional study using a quantitative method of data collection and was conducted among primary school children of age group 5-11years in Delhi area. A total of 1100 school-going children were evaluated. After enumeration and questionnaire administration, visual acuity and exposure time of digital display devices noted, followed by examination of anterior and posterior segment structures of the eyes of the children. For the analysis, children were divided into 3 groups: Group 1 (5-7 years), Group 2 (8-10 years) and Group 3 (below 11 years) based on age.A total of 1100 school children (625 boys and 475 girls) participated in the study. A total of 282 (25.6%) children had visual impairment and 315 (28.6%) children had ocular morbidities. The common ocular morbidities identified were refractive error 25.6%, colour vision defective 0.9%, convergence defect 1.8% and squint 0.2%. The older age group (8-10 yrs) had a higher prevalence of refractive error, especially myopia, compared to the younger age group (5-7 yrs) and group (<12yrs) (P < 0.001). A high prevalence of ocular morbidity among school children of age group 8-10 yrs was observed with a positive correlation with exposure time to digital display devices. Refractive errors were the most common ocular disorders.
Aim
To estimate the prevalence of ocular morbidity among primary school children in Delhi area.
Materials and methods
This was a descriptive cross-sectional study. The study was conducted among primary school children of age group 5–12 years in Delhi area. A total of 1,100 school-going children were evaluated. After questionnaire administration, visual acuity, examination of anterior and posterior segment structures of the eyes of the children were carried out. For the statistical analysis, children were divided into three groups: group I (5–7 years), group II (8–10 years), and group III ((<12 years) based on age.
Results
A total of 1,100 school children (625 boys and 475 girls) participated in the study. A total of 282 (25.6%) children had visual impairment and 315 (28.6%) children had ocular morbidities. The common ocular morbidities identified were refractive error 25.6%, color vision defective 0.9%, convergence defect 1.8%, and squint 0.2%. The older age group (8–10 years) had a higher prevalence of refractive error, especially myopia, compared to the younger age group (5–7 years) and group ((<12 years) (p < 0.001).
Conclusion
A high prevalence of ocular morbidity among school children of age group 8–10 years was observed. Refractive errors were the most common ocular disorders. This study emphasized that a simple school visual screening program is effective for the early detection of ocular problems.

BACKGROUNDBlindness due to cataract presents an enormous problem in India, not just in terms of human morbidity but also in terms of economic loss and social burden. Cataract surgery constitutes by far the most common surgical procedure performed under local anaesthesia. Therefore, it is the need of the hour to make the anaesthetic technique painless and effective.
