The use of part-time occlusion for early onset XXXX .

@entity1 @entity735 @entity5770
Eleven @entity1 (9 months to 5 years of age) with intermittent or constant @entity735 on distant gaze were studied to investigate the effect of part-time occlusion. No @entity1 had constant @entity5770 on near fixation. Visual acuity was found to be equal in both eyes. All @entity1 were treated by part-time patching of the non-deviating eye from four to six hours a day and tapered as appropriate. If @entity5770 recurred after conversion to a heterophoria, part-time occlusion was reinstated. With occlusion, all @entity1 converted to hetero- or orthophoria, at least temporarily. Mean follow-up (to last visit or surgical intervention) was 22 months (range 3 to 37 months). Three @entity1 (27%) later developed constant @entity5770 (mean 28.3 months after beginning occlusion) and underwent surgery. Three @entity1 (27%) became and remain orthophoric without further patching. Part-time occlusion for preschool @entity1 with exodeviations that are predominantly unilateral can postpone surgical intervention and convert @entity5770 to orthophoria or @entity5770 .
