Glaucoma damages vision by building pressure in the eye, caused by fluid buildup, age, genetics, or medical conditions. Early detection is crucial, as symptoms may not appear until later stages. Comprehensive eye exams, visual field, and imaging tests confirm the diagnosis. Proper treatment leads to a positive outcome for most patients. Regular eye exams and discussing glaucoma risk with your eye doctor is the best way to protect your vision.
Early diagnosis of glaucoma is crucial in preserving vision and preventing irreversible damage. Regular eye exams and discussing risk factors with your eye doctor can help catch the disease in its early stages. Don't wait until it's too late!

| Result Value | Images & observations |
| Normal Value | Clear eye structures |
| Accuracy | Highly accurate |
| Interpretation | Eye health assessment |
Ophthalmoscopy is a quick, painless exam to assess eye health. It helps detect glaucoma and other conditions. It's non-invasive, done during routine exams.
| Pachymetry | Details |
|---|---|
| Also Known As | Corneal thickness test |
| Purpose | Measures thickness of the cornea |
| Sample | No sample required |
| Preparation | No preparation |
| Procedure | Corneal thickness measured with a probe |
| Test Timing | a few minutes |
| Test Price (INR) | 1,000-2,500 |
| Result Value | Thick in micrometers |
| Normal Value | 535 to 590 micrometers |
| Accuracy | Reliable |
| Interpretation | Cornea thickness significance |
Pachymetry is a non-invasive and efficient method to gauge the thickness of the cornea. It can help diagnose and monitor conditions such as glaucoma and corneal swelling. This Glaucoma Test requires no special preparation and is typically performed during a routine eye exam.
| Visual evoked potential (VEP) | Details |
|---|---|
| Also Known As | Visual evoked response test |
| Purpose | Visual pathway function assessment |
| Sample | None required |
| Preparation | None required |
| Procedure | Scalp electrodes measure visual activity |
| Test Timing | 30-60 minutes |
| Test Price (INR) | 2,000-10,000 |
| Result Value | Visual Stimuli Response Measurement |
| Normal Value | Varies |
| Accuracy | Highly accurate |
| Interpretation | Results help diagnose conditions like optic neuritis & multiple sclerosis |
Visual evoked potential (VEP) test measures the brain's response to visual stimuli, helping diagnose visual problems. It's a non-invasive and painless test, performed during a routine eye exam. Early detection can prevent vision loss.
| Gonioscopy | Details |
|---|---|
| Also Known As | Gonio |
| Purpose | To examine the drainage angle of the eye |
| Sample | N/A |
| Preparation | N/A |
| Procedure | Angle visualization with a special lens |

| Normal Value | 30-45 degrees |
| Accuracy | High |
| Interpretation | Narrow or closed angles can indicate an increased risk of glaucoma. |
Gonioscopy is a simple and painless Glaucoma Test that examines the eye's drainage angle to assess the risk of glaucoma. The test takes about 5-10 minutes and is performed using a special lens.
| Test Name | Optical Coherence Tomography (OCT) | Tonometry | Perimetry |
