Computerized perimetry

Computerized perimetry is a modern method for examining the visual fields that allows detection of peripheral vision defects, assessment of the optic nerve, and diagnosis of retinal disorders. This technique is widely used in ophthalmology for the early detection of glaucoma, neurological conditions, and damage to the visual pathways.

Indications for computerized perimetry

• Diagnosis and monitoring of glaucoma.
• Detection of optic nerve damage (optic neuropathy, optic atrophy).
• Evaluation of visual fields in neurological diseases (stroke, brain tumors).
• Diagnosis of degenerative retinal diseases (retinitis pigmentosa, diabetic retinopathy).
• Assessment of patients with complaints of visual field loss or blurred vision.

How is the procedure performed?

1. The patient fixates on a central point inside the device.
2. Light stimuli of varying intensity appear in different areas of the visual field.
3. The patient presses a button each time a light stimulus is perceived.
4. The computer analyzes the responses and generates a visual field map.

Types of computerized perimetry

• Static perimetry. Evaluates responses to stationary light stimuli.
• Kinetic perimetry. Determines visual field boundaries using moving stimuli.
• Flicker perimetry. Used for detecting early stages of glaucoma.

Advantages of computerized perimetry in Belarus

• High accuracy and objectivity of examination.
• Allows early detection of glaucoma.
• Identifies neurological disorders affecting vision.
• Painless and well tolerated by patients.

In Belarus, computerized perimetry is performed in modern ophthalmology centers equipped with advanced diagnostic systems. This method enables precise assessment of optic nerve function and early detection of glaucoma and neurological diseases.
