The D Chart is a novel test for assessing the degree and location of metamorphopsia (distortion) in the central visual field.

The test was developed by Velichko Manahilov and Niall Strang of the Department of Vision Science at Glasgow Caledonian University and David Yorston and Gerry McGowan of Gartnavel General Hospital. Working with Thomson Software Solutions, the original paper-based test has been adapted to run on a PC and a range of additional features and functionality has been added.

Metamorphopsia is an important symptom of macular disease. The most commonly used method of detection is the Amsler chart, but this is not quantitative. Other methods require good visual acuity, or costly equipment.

The D-Chart offers a simple and effective alternative.
