Two approaches can be employed for the treatment of traumatic optic neuropathy. Conservative therapy primarily uses steroids and surgical intervention that involves optic nerve canal decompression. However, no standard guidelines have been established for this method. Herein, we report the improvement of visual function in three patients after surgical intervention and steroid administration during the acute phase.
Case 1: A 42–year–old man sustained a traffic accident injury; his left visual acuity had deteriorated to light perception upon arrival at the hospital. Emergency surgery involving optic nerve canal decompression was performed; thereafter, his visual acuity improved up to counting fingers in the upper half but remained partially blind in the lower half.
Case 2: A 54–year–old man fell from a bicycle; his left visual acuity had deteriorated to no light perception upon arrival at the hospital. Emergency surgery involving optic nerve canal decompression was performed; following the surgery, his visual acuity improved up to counting fingers.
Case 3: A 46–year–old man who fell from a ladder had his right visual acuity deteriorated to light perception upon arrival at the hospital. Emergency surgery involving optic nerve canal decompression was performed; his right visual acuity improved up to counting fingers postoperatively.
The fundamental principle in the treatment of traumatic optic neuropathy is early decompression of the optic nerve. Therefore, performing optic nerve canal decompression and steroid administration as early as possible is advisable.
