Detecting amblyogenic diseases with the photographic Bruckner test.

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.
