Long-term improvement of stereopsis in intermittent refractive esotropia
Reviewed by Fiona Rowe

This was a retrospective study to review the records of patients with refractive accommodative esotropia (RAET) to determine long-term stereoacuity (SA) improvement in those that showed initial poor or no stereopsis. The study included 79 patients; 54% male and mean age of 6.3 ±1.9 years. Mean follow-up was 11.7 ±1.8 years. At baseline, 31 had initial subnormal SA and 48 had no stereopsis. 29/31 and 47/48 had intermittent deviations. SA improved at the last follow-up in 30/31 and 19/48 patients. The results indicate a chance of improved SA is greater for patients with subnormal SA than those showing no stereopsis, but that no stereopsis does not preclude recovery of this function. Factors associated with SA improvement include smaller initial deviation with hypermetropic correction and fusion at distance fixation.
