PURPOSE: The authors compared detection rates of glaucomatous visual field defects (VFDs) between a conventional rectangular stimulus grid and locally condensed test point arrangements in morphologically suspicious regions. METHODS: The Humphrey Field Analyzer model 630 (HFA I, program 30-2 with a rectangular 6 x 6° grid) was used as the conventional perimetric method. Individual local test-point condensation was realized by fundus-oriented perimetry (FOP) on the Tübingen Computer Campimeter (TCC). RESULTS: In a total of 66 glaucoma patients, or suspected sufferers, 23 showed normal findings and 27 pathological findings with both methods. In 15 cases, normal visual fields were found with HFA 30-2, whereas FOP revealed early glaucomatous functional damage. Only one case showed pathological HFA results, while FOP was normal. Detection rates of VFDs significantly differed between the two methods (p < 0.001; sign test). CONCLUSIONS: FOP, using individually condensed test grids, significantly increased detection rates of glaucomatous VFDs in morphologically suspicious areas compared to a conventional HFA 30-2 technique using equidistant rectangular (6 x 6°) test point arrangements.
