Validation of Smartphone Photography by Paramedics to Screen Amblyogenic Conditions in Children

Introduction: Amblyopia, with a prevalence of 1.6-3.6%, requires early detection before the plastic stage of vision ends at 8-9 years of age. Various treatment modalities exist, emphasizing the importance of amblyopia management awareness among healthcare professionals and the need for improved screening methods. Objectives: This study aims to evaluate the utility of smartphone photography as a screening tool for amblyogenic conditions in children by paramedics. The specific objective is to assess the symmetry of red glow captured by paramedics for detecting amblyogenic risk factors and compare it with expert opinions. Methods: The study includes children aged 6 months to 8 years presenting to the OPD of a tertiary care eye hospital in Uttar Pradesh. It employs a prospective cross-sectional design with a sample size of 245. Paramedics capture photographs and videos of patients’ eyes, following a standardized procedure. Data analysis involves descriptive statistics and comparison tests using SPSS version 16.0. Results: Paramedics captured images meeting quality standards. Analysis of 245 children’s images showed a sensitivity rate of 93.8% and a specificity rate of 88.7%, comparable with traditional methods. Despite identified limitations, paramedics found smartphone screening feasible. Conclusion: The study demonstrates the potential of smartphone photography by paramedics for early amblyopia detection in children. Findings support its integration into healthcare systems, offering cost-effective, user-friendly, and widely applicable screening solutions. Future research should focus on refining protocols and enhancing technology to optimize reliability and promote widespread adoption, thus improving public health outcomes in mitigating visual impairments among children.
