Abstract
Introduction: In moderate esotropia there is a di1emma whether to operate on one muscle, performing a large unilateral recession (МRR) or on two muscles, performing traditional bilateral (ВМRR) recessions of medial rectus muscles.
Aim: То compare the effect Δ/mm recession of a large МRR and traditional BМRR in moderate esotropia as well as the motor outcome 6 months after surgery.
Material and methods: 200 patients with alternating/alternated esotropia were operated on for the period of 2000-2014. BМRR were performed in 170 patients (З40 eyes), the traditional (up to 5 mm) being in 16 (8%). Their effect Δ/mm recession was compared to the effect of large МRR which was performed in ЗО cases.
Diagnostic, surgical and statistical methods were used.
Results: No statistical difference was recorded between the two groups neither in the effect ?/mm recession, nor in the motor outcome 6 months after surgery.
Conclusion: Large MRR is a good alternative of traditional BMRR for achieving an optimal effect with a minimal surgical risk, especially in cases with preexisting anisometropia and amblyopia.
