Temporal wedge visual field defect in glaucoma

While it is recognised that glaucoma can cause diffuse, non-specific losses in sensitivity in the visual field (VF), specific localised losses in VF sensitivity are considered most useful diagnostically. Nasal step, arcuate and paracentral ‘nerve fibre bundle’ VF defects represent the characteristic pattern defects that occur in glaucoma 1, 2 and typically reflect the course of retinal nerve fibres respecting the nasal horizontal meridian. Commonly, glaucomatous VF loss occurs in the upper hemi-field and affects paracentral regions.3-5 In contrast, glaucomatous pattern VF defects that are temporal wedge in nature are much less common 6 and are arguably less well recognised as a result. In this short article we present the case of a patient with a temporal wedge VF defect due to glaucoma.
