Classical and modern theories for the basis of amblyopia.
The decreased acuity in amblyopic eyes may be the outcome of motor and/or sensory anomalies. Eccentric fixation could be a major contributor. The sensory loss may result from some impairment in the sustained system, possibly caused by inadequate stimulation at a sensitive period for development. Strabismic amblyopia tends to be more of a central retinal problem, the peripheral retina approaching normal activity. As in non-amblyopic eyes, amblyopes have size-selective channels, but perhaps there is insufficient co-operation between these channels.
