Artificial intelligence techniques for automatic screening of amblyogenic factors.

Purpose: To develop a low-cost automated video system to effectively screen children aged 6 months to 6 years for amblyogenic factors.

Methods: In 1994 one of the authors (G.C.

Video vision development assessment in diagnosis and documentation of microtropia.

Background: Microtropia is under diagnosed in treated esotropia and in primary microtropia cases, where patients are young and uncooperative.

Method: Video Vision Development Assessment (VVDA) testing, which we have developed and previously described, captures multiple video frames images (30 per second) of the Breuckner red reflection (from the ocular fundus, a test for strabismus and ocular media abnormalities) combined with eccentric photorefraction. This method allows the highly critical discrimination of minimally off axis fixation (abnormal) to be differentiated from true on axis fixation (normal foveation) by the brightness difference in the images.

Congenital pupillary-iris-lens membrane with goniodysgenesis.

Background: A unilateral congenital pupil-iris-lens membrane with goniodysgenesis syndrome, not benign tunica vasculosa lentis, was first described by Cibis et al. One of three cases developed angle closure. Robb described catastrophic vision loss from angle closure in one of his seven cases.
