How is fundus photography used in the treatment of glaucoma?

Laura C. Fine, MD
If you have glaucoma (a group of eye diseases that cause vision loss through damage to the optic nerve), your ophthalmologist may use a technique called fundus photography to produce three-dimensional pictures of the optic nerve, which serve as a baseline for later comparisons of the nerve. A change in its appearance usually means that pressure has not been controlled and more aggressive treatment is needed. Several newer techniques to create computer-generated images that analyze fiber layers of the optic nerve (nerve fibers that transmit visual impulses to the brain) are also available. Over time, they can help to detect the loss of optic nerve fibers, allowing the doctor to track the progression of the disease.
