Glaucoma Diagnosis: 7 Simple Tests For Eye Health

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.

 

7 Glaucoma Diagnosis Tests

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!

 

Here are some common tests used to diagnose glaucoma:

  1. Optical coherence tomography (OCT)
  2. Tonometry
  3. Perimetry
  4. Ophthalmoscopy
  5. Pachymetry
  6. Visual evoked potential (VEP)
  7. Gonioscopy

Perimetry is a visual field test that measures peripheral vision and can detect early signs of glaucoma and other eye diseases. It's a painless, non-invasive test that can be performed during a routine eye exam and provides valuable information for early detection and treatment.

 

4. Ophthalmoscopy

  • Ophthalmoscopy is a quick, painless eye exam that can detect a range of eye diseases and conditions.
  • The test involves examining the inside of the eye, including the retina and optic nerve.
  • It can help with early detection and monitoring of eye diseases like glaucoma and diabetic retinopathy.

Preparation None required
Procedure Exam of eye structures
Test Timing 5-10 minutes
Test Price (INR) 500-2000
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.

 

5. Pachymetry

  • Measures corneal thickness for accurate glaucoma diagnosis and surgery planning.
  • Quick, painless, non-invasive test with no preparation or recovery time.
  • High accuracy and reproducibility make it a valuable tool for eye care professionals.
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.

 

6. Visual Evoked Potential (VEP)

  • Visual system response test using electrical activity measurement.
  • Helps diagnose vision problems and neurological disorders affecting the visual system.
  • Non-invasive, painless, and can be done in both adults and children.
Visual evoked potential (VEP) Details
Also Known As Visual evoked response test

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.

 

7. Gonioscopy

  • Helps diagnose glaucoma by examining the drainage angle in the eye
