Visual field testing is an important part of regular eye care for people who are at risk for vision loss from disease and other problems. Make the correlation between structure, function. To check for a suspected eye problem or monitor the progress of an eye disease, your ophthalmologist will rely on more specific tests to measure how you see objects in your field of vision. Temporal extension of the field defects below the horizontal meridian occurred in 5 fields. If the first visual field test is read as abnormal or inconclusive because it was inaccurate, it may need to be repeated. Determining if the rate of progression will affect visual function and quality of life is important when making the decision to proceed with escalating therapy that carries increased risk of side effect.
