Abstract

Aims This study aimed to compare the efficacy of medial rectus slanting recession and the bilateral medial rectus Faden with or without recession in the management of any type of convergence excess esotropia with low or high accommodative convergence/accommodation ratio. Patients and methods A total of 38 patients with convergence excess esotropia were divided into group A, which underwent bilateral medial rectus recession according to the average angle of near and distance, and group B, which underwent bilateral medial rectus Faden technique with or without recession. All patients who met the inclusion criteria of the study had complete ophthalmic examination done including deviation angle measurement for near (NCC) and for far (DCC). Patients were followed up immediately, 6 months, and 1 year after the operation. Results At all follow-up times, postoperative NCC and DCC measurements revealed high frequency of ortho and residual esotropia of 10 PD or less in both groups with no significant differences (P > 0.05). There was a significant decrease in the mean ranks of each of NCC and DCC at the postoperative follow-up times (immediately, 6 months, and 1 year) in comparison with the preoperative measures (P < 0.05). Alternatively, comparison of NCC and DCC measured at immediate, 6 months, and 1-year postoperative follow-up times revealed no significant differences (P > 0.05). Conclusion The slanted recession and Faden with or without recession on bilateral medial rectus muscles were effective in reducing the near-distance disparity esotropia regardless of the level of accommodative convergence/accommodation ratio, with stability of results throughout a follow-up period of 1 year.
