Abstract
Traumatic optic neuropathy is an uncommon cause of vision loss due to damage to the optic nerve following trauma. Classified based on mode of injury into direct and indirect. Our study aims to describe demographic and clinico-anatomical factors in TON.
Methods-Retrospective descriptive study included 14 patients diagnosed with TON in 1yr presenting to a tertiary care center. Records were reviewed and data collected.
Results – Mean age was 38.2(+15,2yrs) with Male to Female ratio 13:1.RTA was the commonest cause(11/14) and Indirect was commonest type(11/14).Vision was NLP in 3/14, severe loss in 1/14 and mild in 5/14. All patients received IVMP as per institute protocol, only 6/14 received it within 24 hours. CT-orbit showed fracture in ≥3 walls in 9/14(64.3%).Sphenoid bone fracture was seen in 12/14 cases. Displaced fracture seen in 10/14(71.4%) with impingement in 3/14. Moderate to Severe TBI was seen in 9/14 of which 3 had moderate disability according to Glasgow outcome scale.
