Expansion of binocular fields in the treatment of lateral rectus paresis

Purpose: The purpose was to study the expansion of binocular fields in patients of chronic lateral rectus paresis (LR paresis) treated by bilateral medial rectus recession (BMRr) and compare with ipsilateral recession resection. Methods: A total of 20 patients of chronic LR paresis were randomly div...

Description
Summary:Purpose: The purpose was to study the expansion of binocular fields in patients of chronic lateral rectus paresis (LR paresis) treated by bilateral medial rectus recession (BMRr) and compare with ipsilateral recession resection. Methods: A total of 20 patients of chronic LR paresis were randomly divided into two groups of 10 patients each. In Group A, ipsilateral recession resection was done, while in Group B, BMRr was performed. Results: In Group A, the mean deviation for distance was 40.10 ± 10.8 prism diopter (PD) and, for Group B, was 41.70 ± 12.2 PD preoperatively. Postoperatively, eight (80%) cases in Group A and nine (90%) cases in Group B achieved acceptable alignment (± 10 PD) in the primary position (P = 0.3). Field of binocular single vision (BSV) increased from a mean value of 70% to 77.7% in Group A and from 68.8% to 79.2% in Group B (P = 0.01)) after 6 months. Conclusions: BMRr is an equally effective option for chronic unilateral LR paresis and gives a wider field of BSV as compared to ipsilateral recession-resection surgery.
