April 2, 2025The Essential Glaucoma Tests You Need to Know About | Gupta Eye Hospital
Glaucoma is a leading cause of irreversible blindness worldwide, often progressing without noticeable symptoms until significant vision loss has occurred. Early detection through specialized glaucoma tests is crucial to preserving eyesight. At Gupta Eye Hospital, Panipat, we offer advanced diagnostic tests to detect and manage glaucoma effectively.
What is Glaucoma?
Glaucoma is an eye disease that damages the optic nerve, usually due to increased intraocular pressure (IOP). This nerve is responsible for sending visual information to the brain. If left untreated, glaucoma can cause permanent blindness. Since it often develops silently, regular eye check-ups are essential for early detection.
Who Should Get Glaucoma Tests?
You may be at higher risk for glaucoma if you:
- Are over 40 years old
- Have a family history of glaucoma
- Suffer from diabetes or hypertension
- Experience frequent headaches or blurry vision
- Have a history of eye trauma or surgery
- Use steroid medications for an extended period
Essential Glaucoma Tests at Gupta Eye Hospital
At Gupta Eye Hospital, we use the latest technology and techniques to diagnose glaucoma at its earliest stages. Here are the essential tests you need to know about:
1. Tonometry – Measuring Eye Pressure
Tonometry is the primary test to measure intraocular pressure (IOP). High IOP can lead to optic nerve damage, increasing the risk of glaucoma.
Types of Tonometry:
- Applanation Tonometry – A small probe gently touches the eye’s surface to measure pressure.
- Non-contact Tonometry (Puff Test) – A quick puff of air tests eye pressure without direct contact.
2. Ophthalmoscopy – Examining the Optic Nerve
This test uses a specialized device to inspect the optic nerve, which can show signs of glaucoma damage. The doctor checks for:
- Changes in optic nerve shape
- Cupping (increased depression in the optic nerve head)
- Color changes indicating damage
3. Perimetry (Visual Field Test) – Checking Peripheral Vision
Glaucoma often affects side vision (peripheral vision) first. A visual field test detects any blind spots that may indicate glaucoma.
How It Works:
- You focus on a target while responding to flashing lights appearing in your side vision.
- Missed lights may indicate early vision loss caused by glaucoma.
4. Pachymetry – Measuring Corneal Thickness
This quick and painless test measures the thickness of your cornea using an ultrasound probe.
Why It’s Important:
- A thin cornea can lead to underestimation of eye pressure and a higher glaucoma risk.
- A thick cornea can cause overestimated IOP readings.
5. Gonioscopy – Examining the Eye’s Drainage System
Glaucoma occurs when the eye’s drainage system (trabecular meshwork) becomes blocked.Gonioscopy helps determine:
- If the angle between the iris and cornea is open or closed
- If fluid drainage is normal or obstructed
- Whether a patient has open-angle or closed-angle glaucoma
6. Optical Coherence Tomography (OCT) – Imaging the Optic Nerve
OCT is an advanced imaging test that provides high-resolution, cross-sectional images of the optic nerve.
Why OCT is Crucial:
- Detects early nerve fiber loss before vision is affected
- Monitors disease progression over time
- Helps guide treatment plans
