What visual field defect finding would indicate referral for glaucoma?

Referral for glaucoma is indicated when visual field defects demonstrate changes that are consistent with glaucoma. This typically includes specific patterns of peripheral vision loss, commonly recognized in conditions related to glaucoma, such as arcuate defects, nasal steps, and general constriction of the visual field. These changes signify damage to the optic nerve due to increased intraocular pressure, which is a hallmark of glaucoma.

When a visual field defect aligns with established patterns of glaucoma-related damage, it becomes essential for further evaluation and management. The identification of such findings can guide the healthcare provider to take appropriate steps, which may involve further diagnostic testing, monitoring, or initiating therapy to prevent progression of the disease and preserve vision.

Other choices, like improved peripheral vision, indicate a negative finding toward glaucoma, whereas no visual field defects or only minor distortions suggest that the condition may not be present or significant enough to warrant immediate referral. Thus, identifying visual field changes consistent with glaucoma is crucial for timely intervention.
