How visual fields work
The visual field testing machines use screeners to look inside of the patient’s eye. Typically, sources of light will help to illuminate the inside of the eyes, allowing the examiner or ophthalmologist to achieve a comprehensive review. There are also capabilities to allow the visual field to detect blind spots, eyelid issues, and damage to the optic nerve. During the exam, the ophthalmologist will ask the patient to cover one eye at a time, while the other eye looks into the machine. The patient will try to describe what they see in the distant field of vision, allowing the examiner to take notes in order to determine how healthy the structures of the eye are.
About visual fields
Visual fields are a crucial part of an eye exam and are used almost every time a patient comes into the ophthalmologist’s office. The visual field machines are meant to measure the entire range of the patient’s vision, but are also specifically good for catching any abnormalities. These abnormalities could be disease, scotomas, nerve damage, glaucoma, or more. Depending on the patient’s reaction to the images in the machine as well as their description of what they see, the ophthalmologist will be able to easily determine if the patient has any abnormal or damaged structures within the eye. The shape of the eye can easily diagnose a disease or other eye problems, and the examiner will want to get that taken care of right away.
