Objective: To evaluate the effect of ocular trauma on color vision and contrast sensitivity function on pediatric population.
Methodology: It was an observational study conducted DHQ hospital Jaffaradabad from September 2023 to June 2024. A sample of 377 children aged 5-12 years with recent ocular trauma was included, excluding those with pre-existing ocular conditions or severe systemic diseases. Comprehensive ophthalmic examinations were conducted, including visual acuity using LogMAR charts, color vision with Ishihara plates, and contrast sensitivity with Pelli-Robson charts. Data was recorded and analyzed through SPSS to assess the impact of ocular trauma on these visual functions in the pediatric population.
Results: Our findings show that children aged 9-10 years had the highest number of injuries (135 cases), with pen injuries (18.6%) and wood injuries (19.9%) being most common. Corneal foreign bodies (20.4%) and hyphema with iris injury (20.2%) were frequent. Visual acuity was mostly 20/50-20/200, contrast sensitivity was <2.00, and most had normal color vision. A significant moderate negative correlation (-0.295) between contrast sensitivity and color vision indicates poorer contrast sensitivity may lead to color vision deficiency post-injury.
Conclusion: Our study highlights the significant impact of ocular trauma, with common injuries like corneal foreign bodies and hyphema with iris injury leading to varied visual acuity outcomes. Notable deficiencies in contrast sensitivity and color vision underscore the need for targeted prevention and comprehensive management strategies.
