Automated static perimetry to evaluate diabetic retinopathy.
The Octopus automated static perimeter was used to evaluate patients with early diabetic retinopathy. It showed islands of threshold sensitivity depression that were equal to areas of nonperfusion seen on fluorescein angiography. The geographic area of the fundus at risk of developing these field defects was found to be between 20 and 45 degrees, representing the central area of the midperiphery. This procedure has potential as an excellent screening test for early diabetic retinopathy.
