Abstract
INTRODUCTION: Blindness is a major public health problem in most developing countries. One of the most important preventable and avoidable cause of blindness is corneal injuries. Cornea is the most anterior structure of the eye and it is exposed to numerous hazards. Cornea is the major refracting surface of the eye, even minor changes in its contour result in significant visual problems. By understanding the different types of injuries to which the cornea is exposed the practitioner may more capably manage these injuries and minimise the structural and visual sequelae of corneal injury. AIM AND OBJECTIVE: To study the various patterns of corneal injuries and its outcome among patients of ocular trauma attending our tertiary care hospital. MATERIAL AND METHODS: An institution based study of 133 cases of corneal injuries who fulfilled the inclusion and exclusion criteria. Detailed history taking, visual acuity and corneal examinations were recorded. Direct and Indirect ophthalmoscopy, B scan examination were studied. Investigations like RBS, FBS, PPBS, HIV, HBSAG, Urine routine examinations, X-orbit, CT–orbit were done. RESULTS: In this study, the commonest corneal injury was found to be External foreign body, followed by blunt injury, penetrating injury and chemical injury. The most common affected age group were 21- 30 years. Males were more affected than females. Industries were the most common location for the injuries. Domestic injuries were the second most common. Depth of corneal involvement and state of the cornea had great impact on the visual outcome. Central cornea was commonly involved in most of the injuries. Most of the patients were treated with medical management. Most of the treated patients had clear cornea with proper line of management. Full thickness corneal injury had poor visual outcome. Early intervention had good visual acuity. CONCLUSION: In this study most of the patients who reached hospital within 24 hours had very good visual prognosis. Full thickness corneal injury had poor visual outcome. In most of the cases corneal injuries are preventable. It appears that early treatment can restore good vision and use of eye protective glass while working will be the preventive measure, and use of antibiotics drops after injury will be the proper method of treatment.
