OCT and Visual Field

Optical Coherence Tomography

Optical coherence tomography (OCT) is a form of imaging that utilizes light waves to give a cross-sectional image of your eye. This diagnostic tool is a pain-free, non-contact imaging device. OCT imaging is used in patients with glaucoma, macular degeneration, and other retinal disorders, corneal diseases and scarring, as well as other various eye conditions.

Visual Field

Visual field testing, or automated perimetry, allows your doctor to assess if any peripheral vision loss or abnormal blind spots in your vision (scotomas) are present. This test allows your doctor to determine if any damage has occurred to structures in the eye, optic nerve, or brain. The test is typically performed one eye at a time with the patient’s current glasses prescription in place. In conditions such as glaucoma, where the disease causes slow, progressive visual field loss, a baseline visual field is often used for comparison to subsequent tests. These comparisons allow your doctor to assess if the condition is stable or progressing over time.
