Analyzers, Physiologic, Visual Function, Visual Acuity/Macular Integrity, Bright Light

Definition : Visual function analyzers designed to measure and evaluate visual acuity and macular integrity under several bright light conditions (i.e., brightness acuity). These analyzers typically consist of an electrically powered device that provides several intensities of light to the patient's eye when using the best possible correcting lens (i.e., eyeglasses or contact lenses); visual acuity and macular disturbances are checked under those conditions. Testing visual acuity under bright light conditions facilitates the assessment of opacities and/or distortions in the ocular media (e.g., corneal opacities, opacities following cataract surgery); macular test under bright conditions (i.e., photo stress macular test) is intended to detect macular disturbances such as macular edema and senile macular degeneration
