ENTOPTIC IMAGE QUALITY OF THE RETINAL VASCULATURE

Spatial details of entoptically visible retinal vessels were investiga ted using transcleral and Maxwellian-view stimulators. Nine normal sub jects provided detailed drawings of the entoptic images which were dig itized and superimposed onto digitized fundus photographs and fluoresc ein angiograms from the same eyes. Subjects also used a tracing method to locate visible entoptic features. The trans-scleral method provide d images similar in detail to standard fundus photography (lacking cap illary detail, but capturing larger arteries, veins, arterioles and ve nules) in the macula and around the disk. The Maxwellian-view method i lluminated the fovea (7.7 degree field) and provided foveola capillary detail (capillaries traversing the foveola, the capillary arcade form ing the FAZ) as well as the larger foveal vessels supplying the foveol a, and often contained more foveal detail that available with fluoresc ein angiography.
