Full Form of IOP
What is IOP?
Intraocular Pressure (IOP) refers to the fluid pressure inside the eye, maintained by the balance between production and drainage of aqueous humor. It is a critical parameter in ophthalmology, especially for diagnosing and managing glaucoma, which is a leading cause of irreversible blindness globally. In India, where glaucoma affects over 12 million people and is often detected late, regular IOP measurement is a cornerstone of eye health screening, particularly in primary health centres and tertiary eye hospitals like Aravind Eye Care and Sankara Nethralaya. IOP is measured using a tonometer, with normal values ranging from 10 to 21 mmHg. Elevated IOP is a major risk factor for glaucoma, but normal-tension glaucoma also exists, making comprehensive evaluation essential. The test is routinely performed during eye examinations for individuals above 40, those with family history of glaucoma, or diabetes. In medical education, IOP is a frequently tested topic in NEET PG, AIIMS, and other postgraduate ophthalmology entrance exams, where students must understand its physiology, measurement techniques (Goldmann applanation, non-contact tonometry), and clinical significance. Management of high IOP involves medications (prostaglandin analogues, beta-blockers) or surgical interventions like trabeculectomy. Thus, IOP remains a vital tool in preserving vision and preventing blindness across India.

Example
The ophthalmologist checked the patient's IOP using a Goldmann applanation tonometer and noted it was 28 mmHg, indicating a high risk for glaucoma.
IOP — frequently asked questions
What is the full form of IOP?
IOP stands for Intraocular Pressure, which is the pressure exerted by the fluid inside the eye.
How is IOP measured in eye clinics?
IOP is most commonly measured using a Goldmann applanation tonometer after numbing the eye with drops, or via a non-contact (air puff) tonometer during routine screenings.
What is a normal IOP range and when is it considered high?
Normal IOP ranges from 10 to 21 mmHg. Values above 21 mmHg are considered elevated and may indicate risk of glaucoma, though individual variation exists.
