Blue-on-yellow perimetry in patients with primary open-angle glaucoma / 浙江大学学报·医学版

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the early changes of the blue-on-yellow (B/Y) perimetry in patients with early primary open-angle glaucoma(POAG).</p><p><b>METHODS</b>Thirty-one cases (45 eyes) of POAG underwent the central 30 degrees field examination of B/Y as well as routine white-on-white (W/W).</p><p><b>RESULT</b>No significant difference of mean index deficiency (MD) between B/Y and W/W perimetry was detected (P>0.05). However, there were marked changes in index GHT (glaucoma hemisphere test) and more defect points in B/Y visual field than those in W/W (P<0.01).</p><p><b>CONCLUSION</b>B/Y perimetry might be more sensitive than W/W perimetry a potentially more and valuable method in detection of early POAG lesion.</p>
