Abstract

100 eyes with suspected or proven glaucoma were examined with the Humphrey Field Analyzer 620 with 30-1 and 30-2 threshold tests, complementary 6 degrees grids which combine to a 4.2 degrees grid. The two tests were compared with each other in the resulting 68 pathological fields. 29 of them showed obvious differences in detection of scotomas. In 11 fields, the differences were so great that isolated consideration would have led to an incorrect staging of the glaucoma. Therefore, at present both tests should be applied in glaucoma cases. The frequency of different scotoma detection per test location was more than 10 times higher in the center than in the periphery. It is suggested that a program is developed with a 3 degrees grid within 10 degrees eccentricity, a 4.2 degrees grid between 10 degrees and 20 degrees and a 6 degrees grid between 20 degrees and 30 degrees eccentricity.
