Occlusion for amblyopia: a comprehensive survey of outcome

Eye (Lond). 1992:6 ( Pt 3):300-4. doi: 10.1038/eye.1992.59.


The results of a long term follow up of all patients from a single health district started on occlusion for amblyopia in 1983 are reported. Three hundred and sixty-eight patients started treatment, their average age was four years seven months, the average amount of daily occlusion was 1.5 hours and the average length of follow up was 31 months. 37% of cases achieved a final visual acuity of 6/9 or better and another 33% a visual acuity of 6/12 or 6/18.23% did not achieve 6/18 and treatment of these patients was regarded as failure. Data for the remainder (7%) were incomplete. The success rate of occlusion treatment varied little with the age of starting treatment. The group with combined strabismus and anisometropia responded least well to treatment.
