Abstract
PURPOSE: To evaluate monocular accommodation changes after strabismus surgery with and without anterior ciliary vessel preservation. METHODS:Sixty patients with horizontal concomitant strabismus who were scheduled to undergo monocular strabismus surgeries were randomly divided into two groups: A (without anterior ciliary vessel preservation) and B (with anterior ciliary vessel preservation). Group A was further divided into groups A1 (surgical eyes without anterior ciliary vessel preservation) and A2 (corresponding nonsurgical eyes). Group B was further divided into groups B1 (surgical eyes with anterior ciliary vessel preservation) and B2 (corresponding nonsurgical eyes). Monocular accommodative amplitude (AA) and accommodative facility (AF) were evaluated before and 1 day after the surgery to assess accommodation. RESULTS: In groups A2, B1, and B2, the AA and AF values showed no significant difference preoperatively or postoperatively. However, compared with preoperative values, both the postoperative AA and AF values were significantly reduced in group A1. CONCLUSION:Strabismus surgery without anterior ciliary vessel preservation reduces monocular accommodation, whereas strabismus surgery with anterior ciliary vessel preservation protects accommodation.
