New early detection system for glaucoma

Heidelberg Engineering premiered its new perimeter technology at this year's World Glaucoma Congress in Singapore.

The Heidelberg Edge Perimeter (HEP) utilizes a new stimulus called Flicker Defined Form, which targets M-cells and has been shown to be highly sensitive to functional loss due to early glaucoma. Using flickering black and white patterns, the stimulus creates an illusory edge where the patient perceives a circular stimulus.

Not only does this system target early glaucoma, it is more comfortable for patients, resulting in high test-retest reliability than conventional methods, according to the manufacturers.
