The Visual Field Test is an eye test that measures the scope or coverage of an individual’s eyesight, including the peripheral and the central vision. This is done by an ophthalmologist to know how much vision has been lost over time and how much vision you have in either eye. This test can diagnose if you have scotoma (blind spots) in your eyes. Also, this is done to assess how vision may be affected and limited due to eyelid problems such as ptosis and droopy eyelids.
Generally, this test is used to diagnose further health problems, such as the following:
- Macular degeneration
- Multiple sclerosis
- Temporal arteritis
- Central nervous system disorders
- High blood pressure
- Pituitary gland disorder
- Brain tumor
- Optic glioma
In some cases, after the visual test, if an eye condition is not seen as the cause of any visual problem, the doctor will order blood tests or physical exams to determine the condition accurately.
