“…In another study of this kind, Veronneau‐Troutman, Dayanoff and Stohler 44 compared conventional (direct) occlusion in a group of 53 children aged from five to 14 years, with pleoptic therapy combined with inverse occlusion in 37 children, aged from five to 13 years. Before treatment, the visual acuity of the amblyopic eye was statistically similar in the two groups and was no better than 6/18 in any of the subjects (average values not given).…”

Treatment for amblyopia commonly involves passive methods such as occlusion of the non-amblyopic eye. An evidence base for these methods is provided by animal models of visual deprivation and plasticity in early life and randomised controlled studies in humans with amblyopia. Other treatments of amblyopia, intended to be used instead of or in conjunction with passive methods, are known as 'active' because they require some activity on the part of the patient. Active methods are intended to enhance treatment of amblyopia in a number of ways, including increased compliance and attention during the treatment periods (due to activities that are interesting for the patient) and the use of stimuli designed to activate and to encourage connectivity between certain cortical cell types. Active methods of amblyopia treatment are widely available and are discussed to some extent in the literature, but in many cases the evidence base is unclear, and effectiveness has not been thoroughly tested. This review looks at the techniques and evidence base for a range of these methods and discusses the need for an evidence-based approach to the acceptance and use of active amblyopia treatments.

“…71 The other five prospective CCTs that were found compared different approaches to amblyopia treatment. [74][75][76][77][78] The studies that compared treatment with CAM gratings and either blank discs (instead of gratings) 76 or occlusion 74 found no significant difference in visual acuity between the groups after treatment. Small improvements in visual acuity were seen but the small number of participants in each study limits the value of the findings.…”

Glossary and list of abbreviationsTechnical terms and abbreviations are used throughout this report. The meaning is usually clear from the context but a glossary is provided for the non-specialist reader. In some cases usage differs in the literature but the term has a constant meaning throughout this review. Terms relating to visionAmblyopia Reduced visual acuity in the absence of organic disease, which cannot be improved by spectacles. It is usually uniocular. Amblyopia is held to be reversible up to the age of about 8 years. Children presenting with amblyopia will be treated with occlusion or other therapies in order to reverse the visual loss. It is thought to be caused by hypermetropia and/or anisometropia as well as by the various types of squint. Some practitioners treat these refractive errors in preschool children to prevent the development of amblyopia; others follow-up these children and intervene as soon as the amblyopia appears.Anisometropia A difference in refractive error between the two eyes.

“…Occlusion has been found to be more effective in younger children but it also requires more overall treatment time than required for pleoptics. 36 Practically, pleoptic therapy is very difficult to perform with young children. One important point that should be stressed is that pleoptic studies were generally used on older patients with poorer initial visual acuity and with larger degrees of eccentric fixation, so that a bias in favour of occlusion therapy is evident.…”

Considerations in the routine assessment and treatment of anisometropic amblyopia

Anisometropic amblyopia has traditionally been treated by direct occlusion with or without refractive correction of the anisometropia. This treatment has generally been considered so successful that practitioners prescribe occlusion for a time and consider treatment complete when visual acuity is no longer improving. The aetiology of anisometropic amblyopia, addressing the functional deficits of the amblyopic system and patient compliance issues, are important to the success of amblyopia treatment in anisometropia and are briefly reviewed in this paper. We propose that, while each case of anisometropic amblyopia may have slightly different attributes, initially they should all be treated with occlusion and full-time spectacle correction. Some presentations may be responsive to individual treatment strategies to correct binocular functions such as stereopsis, accommodative response and fusional vergences.
