A visual field test typically takes about 5 to 10 minutes per eye.
This timeframe can vary slightly depending on several factors:
-
Type of Test: There are different methods for performing a visual field test, such as:
- Humphrey Field Analyzer (HFA): A common automated test.
- Goldmann Perimetry: A manual test often used for more complex cases.
- Confrontation Visual Field: A simpler screening test performed by the doctor. The HFA test is the one which has a duration of 5-10 minutes per eye.
-
Patient Cooperation: The test requires the patient to focus and respond accurately when they see a light. Difficulty focusing or responding can lengthen the test.
-
Experience of the Technician: An experienced technician can administer the test more efficiently.
-
Patient's Visual Field Condition: If the patient has significant visual field loss, the test may take slightly longer to map out the affected areas.
While 5-10 minutes per eye is a good estimate, always confirm the expected duration with your eye care professional before your test. This will help you plan accordingly.
