Computer perimetry

Currently, the most accurate and common method of accurate diagnosis of pathology of the optic nerve is computer perimetry. For its implementation, an electronic computer perimeter is used. The device is a spherical perimeter combined with a computer. The study program and the parameters of light objects are set by a medical professional or are set automatically, depending on the need.

After the end of each examination session, the computer displays the results in the form of a summary chart, which the ophthalmologist will have to decipher. The result looks like a three-dimensional chart on which the boundaries of the field of view are indicated by numbers. After drawing on such a map (which in ophthalmology is also called the “visual hill”), you can see where the patient’s visual field boundary ends.

Indications for computer perimetry:

  • glaucoma
  • presence of diseases of the optic nerve
  • retinal dystrophy
  • hemorrhage
  • hypertension
  • a brain tumor
  • head injuries
  • circulatory disorders


  • Allows you to detect changes associated with glaucoma at the earliest stages;
  • It helps to assess the boundaries of the visual field, which often narrow as a result of increased intraocular pressure;
  • Due to its high sensitivity, it reveals even small defects in the central field of view, which may still not manifest themselves in determining visual acuity;
  • Allows you to save the results in computer memory or in hard copy and compare them with subsequent tests, watching the dynamics.


  • You will be asked to sit on a chair in front of the device.
  • Before the examination, one eye will be closed with a bandage.
  • The device has a chin rest and forehead rest, so that you can comfortably fit and fix your head in a position that is optimal for the examination.
  • Inside the hemisphere there is a special mark on which it will be necessary to fix the look.
  • The study is performed with good vision correction, therefore, if you are not wearing glasses or contact lenses, a special frame is usually provided in the perimeter for installing corrective glasses with the necessary diopters. With light degrees of myopia, hyperopia and astigmatism, correction is not required.
  • The health worker will enter your data and install the desired program. Always follow his recommendations (you may be asked not to blink for a few seconds, etc.).
  • During testing, you will be required to press a button on a special remote control as soon as you notice a light object. Depending on the type and purpose of the study, objects may move or remain motionless.
  • The duration of computer perimetry will also depend on the selected program (from 8 to 15 minutes).
  • If during the study you noticed that the lighting inside the device becomes brighter, it dims, do not worry. Continue to perform the test - this is due to the peculiarities of the visual system and the operation of the instrument.
  • While checking the visual fields, you cannot turn your head and take your eyes off the point of gaze fixation you specified - all this will reduce the reliability of the study.
