Computer-assisted perimetry in neuro-ophthalmic disease.

A computer-assisted perimeter has become available commercially and has been evaluated and compared with standard kinetic field testing in patients with neuro-ophthalmic disease. Threshold testing by static means has provided evidence of field defects at a stage usually too subtle to record by standard methods. The machine is quite well standardized and controlled and has had only a few technical problems. Newer programs can be added by means of a change in floppy disk, and this capability promises additional avenues of clinical investigation.
