ABSTRACT
Objective To evaluate the application of blue on yellow(B/Y) perimetry in detecting the early visual field loss of glaucoma. [WT5”HZ]Methods [WT5”BZ]The B/Y perimetry of the G2 strategy in the OCTOPUS 101 perimetry was used to examine the visual field of 16 normal persons (32 eyes), 25 cases (35 eyes) of primary open angle glaucoma (POAG) with abnormal white on white (W/W) visual fields, 15 cases (15 eyes) of early POAG with normal W/W visual field, and 11 cases (22 eyes) of suspected POAG. [WT5”HZ]Results [WT5”BZ]The mean sensitivity (MS) in the normal cases, suspected POAG, early POAG, middle POAG, and late POAG was (23.24?1.22) dB,(20.97?3.42) dB,(18.44?3.57) dB,(11.04?1.85) dB and (8.55?2.29) dB, respectively. It was demonstrated that B/Y perimetry was more sensitive than W/W perimetry in detecting the glaucomatous visual field defects,and its sensitivity was 92% and specificity was 90.62%. The average number of defective points in central visual field with B/Y perimetry was more than that with W/W perimetry in early and middle POAG. Conclusion B/Y perimetry is a relatively sensitive method for detection of the early visual field loss in POAG.
