This device was used to enable fixation, with theeye covered with this apparatus during the testing of the other eye, whichhad a field defect that included the center. Figure Legend:

A, Goldmann perimetry in a simulated central scotoma. RE I4indicates right eye, target size I, and illumination 4. B, Humphrey 30-2 perimetryin a simulated geometric defect. C, Tangent screen in a simulated temporaldefect. 4/1000/w indicates 4-mm white target from 1000-mm distance. Figure Legend:
