New Eye Test Could Delay Vision Loss
Results of a recent study published in the journal Ophthalmic and Physiological Optics show that a new visual field test can detect vision loss related to glaucoma up to 4 years sooner. Glaucoma damages the optic nerve, resulting in irreversible vision loss. It often causes no symptoms in its early stages. That’s why early detection and treatment is so important.
Glaucoma affects peripheral vision first. Tests that are currently used to detect the condition include an eye pressure test, examination of the back of the eye and the optic nerve, and a visual field test.
This new visual field test involves looking at small dots of light of specific sizes and brightness. The inability to see certain dots indicates blind spots in vision and peripheral vision loss—early signs of glaucoma. The test takes into account the fact that the eyes process central and peripheral information differently. The goal is to detect glaucoma earlier and start treatment to slow progression of the disease.
