Predictability of Strabismus Surgery in Children with Developmental Disorders and/or Psychomotor Retardation

Background: Children with developmental disorders and/or psychomotor delay may respond differently to strabismus surgery than children who develop normally, but the literature is conflicting. Methods: We studied 37 patients with spasm, trisomy 21, prematurity, epilepsy, psychomotor retardation, and/...

Description
Summary:Background: Children with developmental disorders and/or psychomotor delay may respond differently to strabismus surgery than children who develop normally, but the literature is conflicting. Methods: We studied 37 patients with spasm, trisomy 21, prematurity, epilepsy, psychomotor retardation, and/or hydrocephalus (study group) and 67 control patients, all between 14 months and 14 years of age. All received a recession of one or both medial rectus muscles (Rc-surgery) or a monocular recession-resection of medial-lateral rectus muscles (RcRs-surgery) for esotropia. Rc-surgery was performed in cases with convergence excess. Spectacles were prescribed prior to surgery for all hyperopia > 2D, all partly accommodative esotropia, and all myopia. Results (effect per mm of surgery): For Rc-surgery, after 2 months follow-up, at 2.5 m fixation distance, the effects (change of angle per millimeter of surgery, mean ± SD) were 2.07 ± 0.82°/mm (study group) and 1.07 ± 0.74°/mm (control group) (P
