Esotropia in Children with Ventricular-Peritoneal Shunts.

PURPOSE

Compared with the general population, patients with hydrocephalus are more likely to have strabismus. This study was undertaken to examine characteristics and outcomes of children with esotropia and ventricular-peritoneal shunt placement due to hydrocephalus.

METHODS

This is a retrospective chart review of all pediatric patients with esotropia and a history of ventricular-peritoneal shunt placement seen by our pediatric ophthalmology service between January 2000 and December 2010.

RESULTS

Sixteen patients between the age of 3 months and 5.6 years met study criteria. Nine were premature and all but one of the patients had developmental delay. Although all patients had a ventricular-peritoneal shunt, the diagnosis leading to shunt placement was intraventricular hemorrhage or congenital hydrocephalus in 75% of the patients. In all but 3 patients the hydrocephalus was diagnosed before the esotropia. Ten children had congenital esotropia and 6 had acquired esotropia. Eleven of the 16 children required glasses: 5 had a myopic prescription and 6 had a hyperopic prescription. Treatment of the esotropia resulted in 9 patients (56%) with successful ocular alignment (<10 prism diopters) on their last visit: 7 underwent strabismus surgery and 2 were treated with glasses only. Of the 9 patients who had strabismus surgery, 6 had congenital esotropia and 3 had acquired esotropia. Among patients who underwent strabismus surgery, 78% had successful ocular alignment at their last visit.

CONCLUSIONS

While acquired accommodative esotropia is more common in the general population, children with ventricular-peritoneal shunts may be more likely to have congenital esotropia. Although developmental delay is very frequent, successful ocular alignment may be possible in this patient population.
