Visual Field Testing (Perimetry) — Hastinapuram

Sri Vision Eye Hospital & Laser Center — Nagarjuna Colony, Phase-4, Hastinapuram

Visual Field Testing (Perimetry) measures the full horizontal and vertical range of vision — central and peripheral — and detects blind spots (scotomas) or field defects. At Sri Vision, we offer computerized perimetry for accurate glaucoma monitoring, neuro-ophthalmic evaluation, and baseline functional assessment before eye surgery.

🔬 Types of Visual Field Tests

• Automated Static Perimetry (Humphrey): Gold-standard computerized test for glaucoma and follow-up.
• Goldmann Kinetic Perimetry: Manual wide-field testing for peripheral defects and neuro-ophthalmic use.
• Confrontation Test: Quick bedside screening for gross field loss.
• 30-2 / 24-2 / 10-2 Protocols: Different test patterns focusing on central vs peripheral fields depending on clinical need.

👥 Who Should Get Visual Field Testing?

• Patients with glaucoma or glaucoma suspects (regular monitoring)
• Those with optic nerve disease or optic disc changes
• People reporting peripheral vision loss, flashes, or visual disturbances
• Patients with neurological symptoms (stroke, pituitary lesions, brain tumors)
• Baseline assessment before major eye surgeries

💡 Quick Tip: Automated perimetry requires patient concentration and steady fixation — tests typically last 5–15 minutes per eye. Results are compared over time to detect progression.

📝 Procedure & Preparation

• You will be seated and asked to look at a central target while lights of varying intensity appear — press a button when you see them.
• Bring your current glasses; do not wear tinted lenses during the test.
• Adequate rest and good sleep the night before improve reliability.
• No special drops are usually required; pupil dilation is not needed for standard automated perimetry.

📊 Interpretation & Follow-up

The specialist reviews reliability indices, grayscale maps, pattern deviation and mean deviation values to identify defects and progression. For glaucoma patients, regular fields (as advised) help guide treatment changes. Abnormal results may prompt further imaging (OCT) or neuroimaging (MRI/CT) referral.
