Both tests evaluate the degree of visual field loss due to the intrusion of either the upper eyelid edge or excess eyelid skin into the visual field (Meyer, 1989; Meyer, 1993). In order to detect a predetermined gene in a field test, a facile, visual, and ultrasensitive approach without the need of special and expensive machines is required. Due to patient complaints of fogging during the testing, low test reliability, and unexpected results, the tests were repeated after taping securely the mask to the bridge of the nose. In order to determine that the droopy eyelid was indeed the cause of the decreased vision, the ophthalmologist performs taped and untaped visual field tests. Most visual field testing is “standard automated perimetry” (SAP). In part one of our checklist used in deciding if insurance covers eyelid surgery, we discovered determining factors within photos taken at time of consultation.
