Intraocular Pressure (IOP) Test – Screening for Glaucoma
The Intraocular Pressure (IOP) Test is used to measure the pressure inside the eyes. Elevated IOP is the primary risk factor for glaucoma, a group of eye diseases that can lead to vision loss and blindness if left untreated.
Indications for IOP Test:
● Routine eye check-ups: Especially in individuals over 40 years of age, as glaucoma risk increases with age.
● Family history of glaucoma: If you have relatives with glaucoma, regular IOP testing is important for early detection.
● Other risk factors: High blood pressure, diabetes, and eye injuries increase the risk of glaucoma.
Methods to Measure IOP:
● Goldmann Applanation Tonometry: The most common method to measure IOP by flattening a small area of the cornea and measuring the force required.
● Non-Contact Tonometry: A puff of air is used to measure IOP without touching the eye.
Normal Range:
● 10–21 mmHg (millimeters of mercury).
Abnormal Test Significance:
● Elevated IOP: Can indicate an increased risk of glaucoma, although not all individuals with high IOP will develop the condition.
Management Based on Results:
● For high IOP: Treatment options include eye drops to lower pressure, laser therapy, or surgery to prevent damage to the optic nerve.
Price in India:
● Approx. ₹500 – ₹1,500 for an IOP test.
FAQs
How often should I get my IOP tested?
If you are over 40 or have a family history of glaucoma, annual testing is recommended.
Can high IOP always cause glaucoma?
High IOP is a significant risk factor for glaucoma, but not everyone with high IOP develops the disease.
Disclaimer:
IOP testing is crucial for detecting glaucoma early. However, high IOP alone does not confirm glaucoma, and further eye examinations are necessary.
