Prognostic factors in traumatic optic neuropathy patients in KhonKaen Hospital

Abstract

          Objective : To investigate the prognostic factors and related demographic data that influence the visual outcome in traumatic optic neuropathy patients at KhonKaen Hospital

          Methods : Sixty-two cases of traumatic optic neuropathy patients presented at KhonKaen Hospital between 2010-2020 were examined retrospectively. Clinical data of the patients, including Initial visual acuity (Initial VA), final visual acuity (Final VA), associated injury, CT images and treatments, were collected. The patients were divided in 2 groups based on the result of the final VA when compared to the initial VA. Statistical analysis were performed to identify associated factors with the visual outcome.

          Result : Most of the patients were male (n=53, 84.13%). Ages were in between 12-67 years old. The most common cause of disease was motorcycle accident (79.37%). Most common associated injury was head injury (90.48%). Eighty-eight percent of the patients had initial VA worse than 3/60. At the end of the treatment, most of the patients had final VA worse than 3/60 (71.42%). The initial VA better than 3/60 was a good prognostic factor that determine the better visual outcome (p-value = 0.036). Treatments with or without systemic corticosteroids were not statistical different in the study.

          Traumatic optic neuropathy had poor visual prognosis. The good initial VA was good prognosis factor. Prevention of accident and the decreasing of accidental severity were recommended.
