Visual field testing is crucial for diagnosing and monitoring diseases, especially glaucoma. Traditionally, an opaque patch covers the non-tested eye, creating darkness and causing visual rivalry, leading to intermittent blackouts and missed targets.
We developed a translucent diffuser that blocks vision but allows light into the non-tested eye, eliminating rivalry and missed targets. This unique device, the “Corrales Visual Field Fatigue Diffuser™,” improves accuracy, reduces fatigue, and speeds up the test. All our visual field tests use this device, proven effective through extensive private practice studies.
