Background: Optic nerve injury can occur with other injuries. It cause a devastating effect to vision.
Objective: To study causes of injury, associated injuries and management of patients with optic nerve injury in Srinagarind Hospital.
Design: Descriptive study
Setting: Department of Ophthalmology,Srinagarind Hospital.
Subjects: Patients diagnosed as optic nerve injury between January 1987 to December 1996.
Intervention: Patients were treated with either intravenous dexamethasone or methylprednisolone for 72 hours.
Measurements : Best corrected visual acuities (BCVA) were determined with Snellen chart before and after treatment.
Results: 49 eyes from 48 patients, 44 male and 4 female, were diagnosed as optic nerve injury. Mean age was 24.52 ± 10.86 years. Median duration of injury was 3 day. The most common cause of injury was motorcycle accident. Most frequent associated ocular injury was lid ecchymosis. Associated head injury and maxillofacial injury were reported 58% and 16% respectively. Before treatment, no light perception was detected in 61.22% of studied eyes. After treatment, 39.58% of patients had better BCVA. Eyes treated with dexamethasone or methylprednisolone had better BCVA 39% and 50% respectively.
Conclusions: Optic nerve injury can occur with head injury and maxillofacial injury. Despite it caused a devastating effect to vision, it could be recovered after intravenous corticosteroid.
