Abstract

In its earliest stages, macular disease is often difficult to confirm by objective means. A patient may report vision problems while little or no macular abnormality is evident upon examination. In a case where tests are inconclusive, the patient may become increasingly concerned with his or her vision and also frustrated by the lack of a certain diagnosis. For these reasons, and for a more complete characterization of the retinal abnormality, a sensitive and objective means is needed to detect retinal dysfunction in the early stages of macular disease.
