Amsler grid test for detection of advanced glaucoma in Ethiopia.

ABSTRACT: OBJECTIVE:This study was done to determine the validity of amsler grid test black on white (BOW), as well as white on black (WOB) for identifying central visual field (VF) defects in patients with advanced glaucoma. DESIGN:Prospective study. PARTICIPANTS:We prospectively included 100 consecutive eyes of 88 adult patients with advanced glaucoma and 100 eyes of 100 normal individuals. We used a lottery method to choose the side of the eye for the control groups. METHODS:All participants had reliable Humphrey 10-2 Swedish Interactive Threshold Algorithm (SITA) standard VF. Both the BOW and WOB amsler grid tests were done for each group. Sensitivity, specificity, and positive and negative predictive values of the amsler grid scotoma area were calculated with the 10-2 VF as the reference standa
