Comparative Evaluation of Functional and Anatomical Outcome of Strabismus Surgery Performed Before Completion of Amblyopia Therapy and After Completion of Amblyopia Therapy in Children Under Nine Years of Age

ABSTRACT

Background: To determine timing of strabismus surgery, is it better to do strabismus surgery before completion of Amblyopia therapy or after completion of amblyopia therapy. Methods: 40 children were taken for this study. These children were divided into two groups of 20 each. Amblyopia was fully treated in group A and in group B children underwent surgery before full treatment of amblyopia in the form of occlusion therapy. Motor success (10 PD of orthophoria) was assessed after three months of surgery and at the child’s most recent visit. Sensory success was assessed by comparing the frequency of detectable stereoacuity. Results: There was no significant difference in motor success (65% vs 80%) and sensory success (65% vs 75%) whether amblyopia was fully treated or partially treated. Conclusion: It is not mandatory to treat ambloypia prior to surgery and amblyopia therapy can be continued post operatively.
