Moorfields Eye Hospital
Researchers at the National Institute for Health Research (NIHR) Biomedical Research Centre (BRC) at Moorfields Eye Hospital and UCL Institute of Ophthalmology in the United Kingdom have designed a new test that can spot the early stages of sight loss in age-related macular degeneration (AMD).
The new test chart, called the Moorfields Acuity Chart (MAC), features letters created from fine black and white strips. Unlike the standard eye chart, these two-colored, high-spatial frequency letters appear to vanish when they are too small to be recognized.
The results of the research were recently published in the British Journal of Ophthalmology. The chart will reportedly be produced commercially and the researchers are preparing to assess the MAC chart's performance in a larger clinical trial.
