With this new way of thinking about amblyopia in mind we developed a method of measuring the degree of suppression and arranging viewing conditions using dichoptic presentation (different images to each eye) where the suppression would be minimal. This new way of thinking about the genesis of amblyopia leads one up a different treatment path, one that tackles the loss of binocular function as a first step with the expectation that the function through the amblyopic eye will improve as a consequence of the reduced suppression from the fellow eye. Recently we have developed tools for measuring suppression and shown that there is a direct relationship between suppression and amblyopia, consistent with the idea that the primary problem is the loss of binocular function with the secondary consequence the development of amblyopia. It seems perfectly feasible that over time this constant suppression leads to a more permanent loss of vision or amblyopia. The link between disrupted binocular vision and amblyopia is suppression.Īll amblyopes have some degree of suppression where the fellow sighted eye inhibits the functioning of the misaligned or out of focus eye to avoid the confusion resulting from a double or blurred image. There is reason to suspect the logic needs to be reversed, namely that the primary problem is that the two eyes, because of either an eye misalignment or an eye out of focus, stop working together with the secondary consequence being amblyopia. The fact that reducing amblyopia with patching does not automatically lead to improved use of the two eyes together makes one question its validity. The current treatment approach is based on the assumption that amblyopia is the primary problem and the loss of binocular function is the secondary consequence. There is no treatment offered to adults with amblyopia.
More significantly there is only a limited time-window in which the patching therapy works, kids are only patched up to the age of 12 years.

The end result after 6 months to 2 years of patching is certainly improved function in the majority of cases, but once the patch is removed the two eyes often don’t work together as they should, 3D vision is often not obtained and the fellow eye suppresses the amblyopic eye, which eventually leads to some reduction in acuity.
The cost in terms of inconvenience and psychological stress for the patient, usually a child at school age, is tremendous and the compliance is often low. In the majority of cases this does produce visual improvements, though there is a great deal of variability. Not too long ago, the patching was all day, but more recently, it has been restricted to 3-6 hrs a day. The treatment for the last 200 hundred years has involved patching of the fellow sighted eye, under the rationale of forcing the “lazy” eye to work. Later, when the alignment is corrected by surgery or the focus corrected with lenses, the visual loss remains.
The disruption to early visual development can be due to a misaligned eye or an eye out of focus. The deficit is not in the eye itself but in the visual areas of the brain.
