Background: Trauma to eye can cause severe and permanent visual impairment. In some instances there may be vitreous hemorrhage, choroidal hemorrhage, globe rupture and traumatic optic neuropathy. Spectral domain optical coherence tomography (SD-OCT) is a quick, sensitive, non-invasive device that provides high-resolution images of the circumpapillary retinal nerve fiber layer (cp RNFL), yielding reproducible and reliable measurements. Aims and Objectives: TO study visual functions (BCVA, CV, CS) and retinal nerve fiber layer thickness by SD-OCT. Materials and Methods: This was a prospective observational study on 108 patients, performed from Sept 2016 to July 2017. RTA patients with visual loss/visual complaints between ages of 18 – 60 years included. Log Mar BCVA, Colour vision and contrast were noted. RNFL analysis was done by SD-OCT. Results: The mean age was 28.33± 8.70 yrs, There were 19 (17.6%) female, 89(82.4%) male in case group. At first visit, there were significant difference between BCVA, CV and CS between right and left eyes of cases and controls. Significant difference were seen in mean RNFL in right and left eye of cases and control. After follow up,insignificant change in BCVA and CV in both right and left eye. Significant change in CS in both right and left eye. Mean change in RNFL thickness was insignificant. Conclusion: Decrease in visual function occurs following RTA. Also, RNFL thinning occurs which remains persistently thin thereafter.
