Computerized visual field testing

• Please bring your glasses with you to the examination (if you use them).
• If the patient wears contact lenses, they should wear them for the duration of the examination, unless the referring physician has recommended otherwise.
• Computerized field of view should not be performed after an eye examination using mydriatic medications.
• The examination requires a great deal of attention and concentration on the patient's part. The field of view is determined based on the patient's reaction to visual stimuli seen on the device, which the patient selects by pressing a reaction button each time.
• During the examination, the patient remains motionless, staring at a single point. In the case of neurological conditions involving involuntary body movements or tremors, obtaining a reliable result may be difficult or impossible.
• The length of the examination depends on the patient's cooperation and response time. The patient is thoroughly instructed on the examination process by the person performing it.

During a computerized visual field examination, the patient reports the presence of moving light spots on the perimeter by clicking the reaction button. The result, obtained as a computer printout, indicates the presence of any visual field defects. A computerized visual field examination is a test that allows for the assessment of disease progression in glaucoma and also aids in the diagnosis of many neurological conditions. The duration is tailored to the patient's needs and reaction time to visual stimuli – the average time is approximately 20 minutes.
