Aim. To com.are rarebit perim.try (RBP) with standard achrom.tic perim.try (SAP) in detecting early glaucom.tous functional dam.ge. m.thods: 43 patients with ocular hypertension (OH),39 with early prim.ry open angle glaucom. (POAG), and 41 controls were considered. Visual fields were assessed using the Hum.hrey field analyser (HFA)30- 2 and RBP tests. Differences am.ng the groups were evaluated using Student-Newm.n-Keuls and χ 2 tests. Correlation between HFA and RBP param.ters was assessed using the Pearson’ s correlation coefficients and regression analysis. Sensitivity and specificity of RBP in detecting early glaucom.tous visual dam.ge were calculated with different algorithm.. Results: RBP-m.an hit rate (m.R) was respectively 88.6% (SD 4.8% ) in controls; 79.1% (10.9% ) in the OH group; 64.3% (13.8% ) in the POAG group (differences statistically significant). Good correlation in the POAG group was found between HFA-m.an deviation and RBP-m.R. Largest aroc.(0.95) and optim.l sensitivity (97.4% ) were obtained when an abnorm.l RBP test was defined as having (at least 1): m.R 15 areas with a non-hit rate of >10% ; ≥ 2 areas with a non-hit rate of >50% ; at least one area with a non-hit rate of ≥ 70% . Conclusions: The RBP appeared to be a rapid, com.ortable, and easily available perim.tric test (requiring only a PC device), showing a high sensitivity and specificity in detecting early glaucom.tous visual field defects.
