Macular function tests are applied for diagnosis and follow up for macular diseases and for assessing potential macular function in eyes with opaque media. One subset of such tests, the Potential vision tests have been devised to assess whether patients with impaired vision have the potential to benefit from cataract surgery. Many such tests have been described in literature namely : 1) Potential Acuity Meter 2) Laser Interferometry (retinometre, visometre) 3) Critical Flicker Fusion Frequency. A brief overview will hereby be presented in the following article.
