Intratrochlear steroid injections in acquired Brown syndrome-a case series.

PURPOSE: To present our experience in the treatment of children with acquired Brown syndrome by means of intratrochlear injection of betamethasone.

METHODS

The medical records of patients treated with intratrochlear betamethasone in 2016 at the Aravind Eye Hospital, Madurai, were reviewed retrospectively. The following data were collected: pre- and postoperative orthoptic work-up, blood work, and neuroimaging. Betamethasone injection was administered 2-8 weeks following onset of symptoms.

RESULTS

Five children (4 girls), 1.5-15 years of age, were included. During the postoperative period, abnormal head posture and elevation in adduction improved in 4 subjects but did not resolve completely. The median vertical deviation was 11.5Δ preoperatively and reduced to 3.5Δ postoperatively. A significant reduction in deviation was demonstrable on diplopia and Hess charting in 2 of the older children. Subject 2, who did not show improvement after injection, was prescribed prism glasses and became diplopia free.

CONCLUSIONS

In this case series, children with acquired Brown syndrome of idiopathic or presumed inflammatory etiology showed significant reduction in deviation and symptoms following intratrochlear injection of betamethasone. We recommend that this treatment be considered for children affected by acquired Brown syndrome, especially those in the amblyogenic age group.
