Abstract
Two automatic computerized perimeters (Perimetron and Octopus 2000) were used to test the visual fields of 43 patients (78 eyes) with open-angle glaucoma in various stages of development. A control group of 14 normal subjects (27 eyes) was also taken into consideration.
The sensitivity of the two instruments was good, with high rates of detection of visual field defects. In the test of normal patients, both instruments demonstrated a good specificity, with a low number of false-positive results.
The automatic perimetry results are very closely connected to the type of program used, the criteria adopted for the classification of test results, the gravity of visual field defects and the level of collaboration of the subject examined.
The most important advantages of the Perimetron and Octopus 2000 over manual perimetry are the objectivity and standardization of the test parameters. An improved fixation control device, and some modification of the software would make the two instruments more reliable.
