Abstract
Infantile esotropia is the most common type of squint in infants. It is a manifest esodeviation with onset before six months of age. It is manifested by large stable angle of deviation more than 30 prism dioptres, fixation in most infants is alternating in the primary position and cross-fixation in side gaze, and the refractive error is usually normal for the age of the child (about +1.5 D) Strabismus neglected in early childhood may cause sever
irreversible sensory anomalies and secondary changes in extraocular muscles which make the surgical correction at a later age less predictable. The prevalence of foveal or macular stereoacuity is significantly higher among those who have surgery before one year of age than those who have the surgery at a later date. Non surgical management is indicated in patients with
hypermetropia more than + 3.00 D. The refractive errors corrected with glasses and amblyopia if present with part time occlusion. The main treatment modality is surgical correction; the operation of choice is bilateral medial rectus recession which is recommended between six and nine months of age In deviation more than 50 prism diopters operation on three or four
muscles had been used. The aim of this study is to evaluate the effectiveness of eight mm
recession of the medial recti for the correction of large angle infantile esotropia and considering it as alternative to operation on three or four muscles. In the current study 16 patients with infantile esotropia were included in the study. They underwent complete strabismological examination, corrected for any refractive error if present and underwent eight mm bilateral medial rectus recession for large angle and followed for six months. In our study a successful motor outcome is defined as orthrophoria or a horizontal tropia of less than 10 D in primary position. The success rate in this study was 68.75% after follow up for six months. There was a statistical relation between the age and final motor results, the younger the patient the better the results.
There was no serious complication as slipped muscle or infection met with in this study.
