Purpose:
Evaluation of the development of binocular functions after surgical treatment in cases with infantile esotropia.
Method:
25 children with infantile esotropia followed in strabismus clinic development of binocular functions after surgery were evaluated. A comprehensive examination was made before and at the 1st day, 1st week, 1st, 3rd and 6th months of the postoperative period. The visual acuity was measured using the Snellen chart. The angle shift in primary gaze position before and after the surgery was measured using the prism reflection test (Krimsky). The fusion was evaluated by Worth's four-point test (W4N) and the stereoacuity was evaluated by Preschool Randot test. According to angle of squint, 5 to 7 mm’s of recession of both medial rectus muscles was applied to the patients.
Results:
The mean age of the patients was 3.36 ± 1.15 and the average age of operation was 2.72 ± 0.98. The mean angle of squint at primary gaze position was 47.20 ± 15.14 PD before surgery, and 7.00 ± 9.68 PD after surgery. The mean amount of medial rectus recession was 5.82 ± 0.72 mm’s. Fusion was detected in 1(4%) patient before the surgery and 7 (28%) after surgery(p> 0.05). Before the surgery 20% (5 cases) of cases had stereoacuity, after surgery this rate reached 56% (14 cases) (p
Conclusion:
In cases with infantile esotropia the early surgical treatment should be applied for the development of the binocular functions.
