Advanced Visual Function Testing

What is Advanced Visual Function Testing?

Advanced visual function testing (AVFT) includes both subjective (psychophysical) and objective (electrophysiological) diagnostic methods for evaluation of the visual function. The purpose of this testing is to use all clinically relevant research findings for the prevention, diagnosis, and treatment of diseases affecting the eye and visual system, including retinal diseases and abnormalities of the visual pathways. They can be used also to evaluate undesirable drug visual side effects and to estimate the visual system performance for the purposes required by federal agencies, such as professional evaluation, legal cases, etc.
