Automated Perimetry & Visual Field Testing for Functional Vision Analysis

A visual field test (perimetry) evaluates the full spatial scope of what your eye can see—measuring both sharp central vision and wide peripheral (side) vision. Because chronic diseases like glaucoma, optic neuropathies, and intracranial neurological conditions first degrade peripheral vision before impacting central clarity, computerized perimetry is essential for identifying hidden blind spots and measuring functional vision loss.

Supervised by Dr. Parul Tripathi, MS (Ophthalmology)—a fellowship-trained glaucoma and vitreo-retina specialist—our Visual Field Testing & Perimetry center uses gold-standard automated Humphrey Visual Field (HVF) analyzers. By measuring differential light sensitivity across hundreds of points on the retina, we capture objective diagnostic baseline maps and monitor long-term clinical response with statistical precision.

01

Automated Static Perimetry (Humphrey Field Analyzer)

The Humphrey Visual Field Analyzer is the global benchmark for clinical visual field assessment. Using fast, threshold algorithms (such as SITA Standard and SITA Fast 24-2 / 30-2 protocols), the machine projects dim and bright light stimuli at varied retinal points while you look at a central target. By recording the dimmest light stimulus perceived at each location, it produces a detailed sensitivity map highlighting microscopic visual depression.

02

Glaucoma Progression Analysis (GPA)

Managing glaucoma involves proving that the disease is clinically stable over time. Glaucoma Progression Analysis (GPA) software uses statistical trend analysis to compare current visual field printouts with baseline tests. This distinguishes true disease progression (e.g., deepening nasal steps or expanding arcuate scotomas) from normal test-to-test variability, helping guide timely medical adjustments.

03

Scotoma & Paracentral Blind Spot Mapping

In advanced glaucoma and specific macular pathologies, microscopic blind spots (paracentral scotomas) can form near central vision. Specialized 10-2 threshold testing focuses tightly on the central 10 degrees of vision with high grid density, detecting early paracentral damage that standard testing might miss and providing critical diagnostic feedback for fine-tuning target intraocular pressures.

04

Neuro-Ophthalmic & Intracranial Field Testing

The optic nerve pathways travel from the eyes through the optic chiasm to the visual cortex in the brain. Perimetry detects signature patterns of visual loss caused by neurological conditions—such as bitemporal hemianopia from pituitary adenomas, homonymous hemianopia from cerebrovascular strokes, ischemic optic neuropathy, or optic neuritis related to demyelinating disorders.

Diagnostic Significance

Objective visual field analysis connects optic nerve structure with real-world functional vision

Combining structural testing (OCT scans) with functional testing (Humphrey visual fields) gives a complete clinical evaluation, ensuring no subtle signs of disease progression go unnoticed.

Early Peripheral Detection

Identifies blind spots and subtle nerve fiber bundle defects long before you notice any blurriness in everyday central vision.

Standardized Reliability Indices

Tracks fixation losses, false positives, and false negatives to ensure test results are clinically dependable and accurate.

Completely Non-Contact

A simple interactive test performed without eye drops or physical contact with the cornea, ensuring a comfortable experience.

Visual Field Testing & Perimetry FAQs

A visual field test is a non-invasive diagnostic examination that measures the full range of what your eye can see while looking straight ahead, mapping both central clarity and peripheral (side) vision sensitivity.

You sit comfortably in front of a bowl-shaped perimeter with one eye patched. As small points of light flash in varying brightness across your field of view, you press a handheld buzzer whenever you see a flash while keeping your gaze fixed on the central target.

Using modern SITA threshold algorithms, the test typically takes approximately 4 to 8 minutes per eye, depending on the test strategy selected by Dr. Tripathi.

Glaucoma damages peripheral vision before central vision is affected. Perimetry provides the primary objective measurement of how well your optic nerve is functioning and confirms whether treatments are keeping your condition stable.

No. The test is simply an objective map of your current visual sensitivity. It is normal to not see every light flash, as the test intentionally includes very dim stimuli below normal perception thresholds to map your visual boundaries.

For newly diagnosed glaucoma or unstable eye pressures, tests may be performed every 6 months. For stable glaucoma patients, testing is generally repeated every 6 to 12 months for long-term progression tracking.
