Abstract
The authors evaluated the photographic Brückner test for its ability to detect the main causes of amblyopia. One hundred four patients divided into four groups underwent this test: Group I, small deviation esotropia; Group II, large deviation esotropia; Group III, anisometropia; and Group IV, healthy controls. The results show high sensitivity (82%), specificity (91%), and accuracy (84%), indicating that this test could be a potential way to mass-screen pre-verbal and pre-school children to facilitate early detection of the main causes of amblyopia, when treatment is still possible.
