Abstract

Objective: To compare unilateral supra maximal lateral rectus recession (ULR) and bilateral lateral rectus recession (BLR) surgery in terms of efficacy and success rate in cases of mild to moderate degree exotropia.

Study Design: Quasi experimental study.

Place and Duration of Study: Combined Military Hospital Multan, Pakistan from Feb 2023 to Jan 2024.

Methodology: 60 patients having exotropia in the prism diopters (PD) range of 10–30 were included in the study. Randomized sampling was done, and the patients were divided into 2 groups. 30 patients with exotropia underwent unilateral lateral rectus recession surgery (Group-A) whereas other 30 patients underwent bilateral lateral rectus recession surgery (Group-B).

Results: After one week of surgery, the angle of deviation in PD was seen to be 3.33±4.17 PD in Group-A and 2.8±4.12 PD in Group-B (p= 0.801). Following each surgical procedure, there was a significant improvement in the angle of strabismus (p<0.05). At final evaluation (3 months after surgery) exotropia improved on average by 15.66±6.28 PD in Group-A & 16.86 ± 4.66 PD in Group-B (p <0.05)

Conclusion: Success rate range was high and comparable in both the groups. When correcting mild to moderate angle exotropia (≤30 PD), unilateral supra maximal lateral rectus recession is more beneficial than bilateral lateral recession because of reduced anaesthesia time, reduced surgical risks such as scleral perforation, retinal detachment and endophthalmitis. Furthermore, the rate of consecutive esotropia and over-correction is decreased.
