 A visual field test, also known as perimetry, assesses the extent of your side (peripheral) vision. It helps detect abnormalities in your field of vision that might indicate eye conditions like glaucoma, stroke, or neurological issues. The test involves identifying lights or objects in your peripheral vision while focusing on a central point.

• Sitting: You'll be seated in front of a machine (perimeter) with a bowl-like structure. 
• Fixation: You'll be asked to fix your gaze on a central target, usually a light, throughout the test. 
• Light Flashes: Lights will flash at various locations within your peripheral vision. 
• Button Press: You'll press a button each time you see a light flash. 
• One Eye at a Time: Each eye is tested separately, with the other eye covered. 

• Early Detection:Visual field tests can detect problems before you notice them, as some conditions like glaucoma can progress silently. 
• Monitoring:They help track the progression of eye conditions and the effectiveness of treatments. 
• Diagnosis:They aid in diagnosing various eye diseases, neurological conditions, and even brain tumors. 

• Glaucoma: A leading cause of vision loss, glaucoma affects peripheral vision.
• Stroke: Damage from strokes can affect the visual field.
• Macular Degeneration: Affects central vision, but can also impact peripheral vision.
• Multiple Sclerosis: A neurological condition that can cause visual field defects.
• Brain Tumors: Can affect vision as they grow.
• Other Neurological Conditions: Including pituitary gland disorders.
