眼壓 Intraocular Pressure
Intraocular Pressure (IOP)
*What is IOP?
Intraocular pressure refers to the pressure inside the eye that maintains the eye's shape, ensures proper optical function, and supports metabolic activities. When IOP rises to a certain level, it can compress the optic nerve, causing atrophy and potentially leading to vision loss or even blindness.
*Normal Range
Normal IOP: ≦20 mmHg
*Symptoms of High IOP
High IOP often has no obvious symptoms, making it hard to detect until vision problems arise. However, some may experience:
-A sensation of pressure or discomfort in the eye
-Blurred vision or narrowed visual fields
-Headaches
-Eye fatigue
*Common Causes of High IOP
-Genetic Factors:
A family history of glaucoma or high IOP increases risk.
-Age:
The risk of elevated IOP increases with age.
-Myopia or Hyperopia:
People with severe nearsightedness or farsightedness are more prone to IOP issues.
-Diabetes or Hypertension:
These conditions are closely linked to high IOP and increase the risk.
-Steroid Use:
Prolonged use of steroids (e.g., eye drops or oral medications) can lead to elevated IOP.
-Eye Trauma:
Past eye injuries or surgeries may result in increased IOP.
*How to Maintain Normal IOP
-Regular Eye Exams:
High-risk individuals, such as those with a family history of glaucoma, should have regular IOP checks.
-Disease Management:
Controlling blood pressure and blood sugar can reduce the risk of high IOP.
-Healthy Lifestyle:
Engage in moderate exercise, eat a balanced diet, and reduce eye strain.
-Follow Medical Advice:
If diagnosed with glaucoma or other eye conditions, adhere to prescribed treatments, such as using medicated eye drops.
*Conclusion
IOP is a critical indicator of eye health. Elevated IOP can lead to conditions like glaucoma, emphasizing the importance of regular IOP checks and timely intervention. Adopting a healthy lifestyle can help minimize the risk of elevated IOP and support overall eye health.
