CLINICAL PROFILE OF PATIENTS PRESENTED WITH POST TRAUMATIC VISION LOSS IN A TERTIARY CARE CENTRE

Purpose: To explore the epidemiological aspects, clinical profile and outcome of TON. Methods: 36 eyes of 36 patients were examined from August 2021 to April 2022 admitted at Emergency department presented with post traumatic uniocular sudden loss or diminution of vision. Visualacuity, fundus examination, OCT, NCCT head with orbit, MRI brain with orbit done in all patients. T-test and Fishers exact test were used as statistical methods. Results: Younger (18- 35 years) age group was more vulnerable to optic nerve injury. Indirect optic nerve injury was more common that direct optic nerve injury. Visual outcome was better in patients presented within 8 hours of injury. Eight patients managed surgically had BCVA (Best corrected visual acuity) at discharge 6/18 to 6/6.Twenty-eight patients who received medical management had BCVA 6/24(V.A.finger count at 3meter). Conclusion: Indirect optic nerve injury was common in cases of TON. Early surgical intervention associated with better visual outcome. Medical managementif started within 8 hours of injury associated with relatively better visual outcome
