But, there is very limited literature on effect of ocular parameters (axial length, medial rectus width and the distance of medial rectus insertion to limbus) to this operation. Objective: To evaluate effects of ocular parameters on medial rectus Faden operations with recession for esotropia. Material and Methods: In this retrospective study, 38 patients (57 eyes) who underwent Faden operation with unilateral or bilateral recession (4 - 4.5 mm) on medial rectus were divided into three groups according to axial length, medial rectus width and the distance of medial rectus insertion to limbus. Preoperative and postoperative deviations compared. Results: 11 cases were infantile esotropia, 46 cases were acquired esotropia. Female/male rate was 19/19. The mean preoperative amount of esotropia at near was 49.95 ± 17.36 prism diopters (PD) and postoperative 1 week 11.77 ± 11.14 PD, 1 month 12.02 ± 11.52 PD and 6 months 9.46 ± 10.19 PD. The mean preoperative amount of esotropia at distance was 38.84 ± 19.03 PD and postoperative 1 week 7.25 ± 11.29 PD, 1 month 6.54 ± 10.52 PD and 6 months 4.40 ± 9.08 PD. Due to axial length, in shorter eyes, the decrease in mean post-operative deviation was statistically significant. Due to medial rectus width and the distance of medial rectus insertion, there was no statistically significant difference. Conclusions: Axial length has an effect on medial rectus Faden operations with recession but medial rectus width and medial rectus insertion distance from limbus do not.展开更多
