Amblyopia: Clinical Aspects

Part of the Wenner-Gren Center International Symposium Series book series (WGS)


We differentiate 2 etiologic lines of amblyopia: 1st stimulus deprivation, 2nd suppression (von Noorden). The majority of our patients suffer from a combination of both: moderate stimulus deprivation (ametropia or anisometropia) with strabism. It is easy to agree with the general definition and classification of amblyopia. On the other hand it seems to me very difficult to draw a line between a normal eye and an amblyopic eye. In our country we treat patients who reach an acuity less than 0.8 Snellen as amblyops. Crowding-phenomenon reduces the line acuity to a level lower than Snellen- or single-symbol-acuity. Again what value of this kind of acuity represents the border between normal and amblyopic eyes?
