Abstract Purpose:Patients with age-related distance esotropia was treated with unilateral resection of the lateral rectus muscle(RLM)or recession of the medial rectus muscle(RMM). The clinical characteristics of this strabismus are discussed after analyzing the results of these surgeries.

Subjects and methods:Unilateral RLM or RMM were carried out as the initial surgery on 13 age-related distance esotropic patients. Results of examinations of strabismus were retrospectively collected before and after the surgery.

Results:The average age at surgery was 74(range 59-85)years. Five patients underwent recession, while 8 patients underwent resection. The angle of esotropia at distance was 9.9Δ(3-18Δ)and −0.2Δ(−3-2Δ), before and after the surgery. The corrected angle per each surgical dose(mm)was slightly larger for RLM than that for RMM.

Conclusion:Both surgeries were effective to correct age-related distance esotropia. However, increasing the surgical dose should be considered when recession of the medial rectus muscle is selected.
