Blue-on-yellow perimetry using an Armaly glaucoma screening program

The purpose of the present investigation was to determine whether blue-on-y ellow (B/Y) perimetry using a screening program can detect early glaucomato us change before it is evident with standard white-on-white (W/W) screening tests. The subjects included 25 normal, 20 ocular-hypertensive and 27 earl y glaucomatous eyes. From our results, even in normal subjects, B/Y perimet ry alone demonstrated abnormal points in the nasal field in 10 eyes (40%). The Armaly central screening program was thought to be superior to the Arma ly full-field program, because the former has less probabilities to detect a false-positive scotoma in the nasal field than the latter. in glaucomatou s eyes, more abnormal points were detected by B/Y perimetry than by W/W per imetry. The screening program of B/Y perimetry is more advantageous than co nventional tests in detecting early glaucomatous visual field defects.
