APPLICATIONS & DISEASE
testing provides early detection of serious eye diseases and/or conditions
that a standard 20/20 letter acuity chart may not detect until the condition
is more advanced. Such diseases and/or conditions include cataracts,
glaucoma, amblyopia, macular degeneration, keratoconus and optic neuritis.
Contrast sensitivity testing has also been shown to detect other types
of diseases and/or conditions including diabetes, cerebral lesions,
AIDS and Alzheimer's disease at early stages, sometimes before other
symptoms may appear.
testing is recognized by the FDA as a more comprehensive and accurate
method of assessing vision in clinical trials. With the advent of new
technology such as the wavefront, intraocular lenses and refractive
surgery, many eye care practitioners and ophthalmic companies are turning
to contrast sensitivity testing to monitor the progress of their patients.
