Near and Distance Stereoacuity in Patients With Primary Open-angle Glaucoma
Park CK; Kim DW; Lee CKJournal of Glaucoma 2018; 27: 537-542
PURPOSE: To compare near and distance stereoacuity between patients with primary open-angle glaucoma (POAG) and a control group, and to analyze the associations between stereoacuity and POAG severity. METHODS: This cross-sectional study compared near and distance stereoacuity between the POAG and control groups. The data from the POAG group were used to assess the associations between stereoacuity (both near and distance) and the severity of visual field (VF) defects (based on Hodapp-Anderson-Parrish classification and the VF index). RESULTS: The study included 94 eyes of 47 patients with POAG and 80 eyes of 40 control subjects. Near and distance stereoacuity were significantly lower in the POAG group than in the control group (both P<0.001). Near stereoacuity worsened with POAG severity in terms of both the Hodapp-Anderson-Parrish classification and VF index (P=0.007 and P=0.049, respectively). However, distance stereoacuity was not associated with POAG severity for either categorization (P=0.12 and P=0.57, respectively). The proportions of patients with reduced near stereoacuity and those with a lack of distance stereoacuity were higher in the POAG group than in the control group. CONCLUSIONS: Near and distance stereoacuity were significantly lower among patients with POAG than among control subjects. Near stereoacuity worsened with increasing POAG severity but distance stereoacuity did not. However, the proportion of patients with a lack of distance stereoacuity was higher in the POAG group than in the control group.
