Visual Field And Impact On Glaucoma Patients´ QoL

Visual field testing is a critical tool in diagnosing and managing various ocular and neurological conditions, from glaucoma to brain tumors. However, misconceptions and myths often cloud its interpretation. This discussion explores the accuracy, limitations, and common misunderstandings surrounding visual field testing. We will differentiate between myths”such as the belief that all visual field defects indicate glaucoma”and facts, like the role of test reliability indices in determining accuracy. By distinguishing fact from fiction, this analysis aims to enhance clinicians and patients understanding of visual field interpretation, ensuring informed decision-making in eye care.

This presentation will address the impact of glaucoma, either visual field defect or other aspects, on patient-reported vision-related quality of life (pVRQOL). In particular, a prospective study which explores how the location of visual field (VF) defects in primary open-angle glaucoma affects pVRQOL will be illustrated. This cross-sectional study included 186 patients with reliable VF tests and best-corrected visual acuity of at least 20/60. The validated Taiwanese version of the 25-item National Eye Institute Visual Function Questionnaire was used to assess pVRQOL. Multivariable linear regression analysis revealed that overall VF impairment correlated with reduced scores in near activities, driving, vision-specific role difficulties, dependency, and peripheral vision. Notably, superior hemifield VF defects were primarily linked to difficulties in near activities, while inferior hemifield defects were associated with impairments in general vision, vision-specific role difficulties, and peripheral vision. These findings highlight the importance of considering both the severity and location of VF defects when evaluating their impact on patients’ quality of life.
