Abstract

Purpose

To report the clinical outcome of patients with consecutive esotropia (ET) in the pre- and post-operative periods and at the last postoperative visit.

Methods

The present study included 12 patients who underwent surgery for the correction of consecutive ET. The angle of deviation, duration of consecutive ET, and surgical and non-surgical methods for correction of consecutive ET were investigated. The sensory status was evaluated before the surgery of exotropia (XT), during consecutive ET and after the surgery for consecutive ET.

Results

The average angle of deviation before the surgery of XT was 27.5 PD and 3 patients had lateral incomittancy. Alternate occlusion treatment was performed in all patients, and 10 patients wore Fresnel prisms. The average angle of deviation of consecutive ET was 24.3 PD. After an average of 30 months postoperative consecutive ET, 9 patients were orthotropic or had deviation within 8 PD, 2 patients had 15 PD ET, and 1 patient had 20 PD XT. There were 3 patients whose stereopsis was aggravated and 1 patient had poorer fusion during consecutive ET, and recovered after the surgery for consecutive ET. No patients had a decrease in visual acuity.

Conclusions

As a result of alternate occlusion and Fresnel prisms during consecutive ET after surgery of XT, the incidence of aggravation in binocularity was low, and the cases with aggravated binocularity were recovered after surgical correction of consecutive ET. The surgical success rate was 75% in consecutive ET.
