Visual field testing, or the Visual Field Test, is a test used to measure the extent of the vision that a person can see without moving their eyes. It is an important diagnostic tool for detecting many eye and neurological diseases. This test helps determine the area the patient can see through, and it can diagnose the extent of damage to the optic nerve and the stage the patient has reached, which helps in treatment and monitoring the condition.
The visual field test is performed at Eye See Center using the latest German device; ZEISS Humphrey Field Analyzer, which is characterized by high accuracy. The visual field is automatically tested, where the patient sits in front of a computer screen and focuses on a bright point in the center of the screen. The device lights up different points in various areas of the visual field, and the patient must press a button when they see each light point.
Uses of Visual Field Test in Eye and Neurological Diseases
- Glaucoma: A disease that affects the optic nerve and causes peripheral vision loss.
- Stroke: It can affect vision in different areas of the visual field.
- Pituitary diseases: It can affect the pituitary gland, leading to peripheral vision loss.
- Brain tumors: These can affect vision in various areas of the visual field.
- Other neurological problems: Such as diabetic retinopathy, retinitis pigmentosa, and cerebrovascular insufficiency diseases.
