Visual Fields in Early Glaucoma: A Review

Abstract

Visual field testing is an essential diagnostic tool for glaucoma, and it involves the measurement of the patient's visual sensitivity over a range of locations in their visual field. In early glaucoma, the visual field changes are usually localized, and they occur in specific regions of the visual field, such as the nasal or temporal field. The visual field defects are often subtle and can be missed without proper testing and analysis.
