An evaluation of visual outcome of corneal injuries in a tertiary care hospital

Abstract

Background: Corneal injuries are significant contributors to blindness. Cornea being the most anterior structure of eye is exposed to various hazards like airborne debris and blunt trauma. By understanding different types of injuries to which cornea is exposed, the practitioner maybe more capable in managing injuries to minimise structural and visual sequelae. Objectives: To study various patterns of corneal injuries and its visual outcome among patients of ocular trauma in a tertiary care hospital. Methods: Study of 100 cases of corneal injuries wherein patients were treated according to injury type and followed up for 4 months. Results: Majority of patients belonged to working population between age groups 21-65 years. Most patients suffered from corneal abrasions while the least common were perforating and lacerating injuries. Alkali injuries were more common than acid injuries. Most patient presented within 24 hours and had only epithelial defects. Therefore, the number of patients receiving conservative management was higher than those receiving surgical intervention. Conclusion: Most common causes of blindness and low vision in our study was full thickness corneal laceration and corneal abrasions, foreign body injuries affecting the pupillary area and involving anterior or mid stroma causing nebular or macular grade opacities hampering vision.
