Visual Field Defects

This information is useful for children, adults, and older adults

When a patient complains of a blind spot or decreased vision, they may have a visual field defect. Visual field defects can be caused by such problems as decreased blood flow to the retina, glaucoma, brain tumor or stroke. In this video, Adeniyi Fisayo, MD, an assistant professor of neurology and of ophthalmology, talks about Yale Medicine’s highly specialized approach to diagnosing and treating visual field defects. Once a patient has been diagnosed, he or she has access to cutting-edge treatment, thanks to ongoing collaboration between Yale Medicine’s research and clinical teams.

Clinical Trials

New treatments for many conditions are tested in clinical trials, which ultimately bring lifesaving new drugs and devices to the patients who need them most. By participating in a clinical trial, you may get access to the most advanced treatments for your condition, and help determine their benefits for future patients.
