The Detection of Paracentral Scotomas With Varying Grids in Computed Perimetry

The Detection of Paracentral Scotomas With Varying Grids in Computed Perimetry Abstract • The ability to identify the physiologic blind spot was reviewed for programs 31 and 32 on the OCTOPUS 201 perimeter. One eye of 100 randomly selected patients suspected of having glaucoma were used in the study. OCTOPUS program 31 failed to identify the physiologic blind spot in 11 eyes (22%), while program 32 missed the blind spot in three eyes (6%). These findings suggest that a 6° grid may not be adequate for identification of scotomas of the size and depth of the physiologic blind spot in the central field. References 1.

Abstract

Abstract • The ability to identify the physiologic blind spot was reviewed for programs 31 and 32 on the OCTOPUS 201 perimeter. One eye of 100 randomly selected patients suspected of having glaucoma were used in the study. OCTOPUS program 31 failed to identify the physiologic blind spot in 11 eyes (22%), while program 32 missed the blind spot in three eyes (6%). These findings suggest that a 6° grid may not be adequate for identification of scotomas of the size and depth of the physiologic blind spot in the central field. References 1.
