Authors' objectives:

This review aims to assess the available evidence on the effectiveness of vision therapy, a set of individualized, non-invasive, therapeutic procedures that are intended to correct or improve the effects of various eye conditions.

Authors' recommendations: With regard to vision therapy, the ICSI Technology Assessment Committee finds: The studies of the efficacy of vision therapy are predominantly poor quality case series which provide inadequate scientific evidence to enable a conclusion to be reached about the efficacy of vision therapy for patients with learning disabilities, amblyopia, strabismus, convergence insufficiency, or accommodative disorders. (Conclusion Grades Not Assignable) The Committee encourages blinded, randomized, controlled trials of vision therapy for the potential uses listed above. These trials should include clearly defined patient populations, control group(s), clearly defined treatment programs, relevant outcome measures, and adequate patient follow-up to determine whether any observed benefits are maintained. Vision therapy is safe when it follows a comprehensive eye examination (including dilation) that rules out a serious condition requiring medical or surgical intervention. A vision therapy program should not delay the individual from receiving medical or surgical intervention, if appropriate. The vision therapy activities, in general, will not exacerbate an existing condition. There are rare cases where anti-suppression therapy for congenital strabismus has resulted in intractable diplopia.
