Intrathecal steroid therapy for post-traumatic visual disturbance

We have given intrathecal injections of dexamethasone more than 2000 times for approximately 200 cases with visual disturbance and 20 cases with sciatic pain. An injection of 8 mg was given once or twice a week until a total dose of 80 to 100 mg was given. Six of the 14 cases that were thus treated in their chronic stage for post-traumatic visual disturbance showed various degrees of improvement in visual fields and acuity. There were no serious complications in this series. It is concluded that intrathecal steroid injection is effective in certain cases of post-traumatic visual impairment.
