Regarding intraocular pressure and glaucoma development risk, which statement is true?

• A. The Higher The IOP, The Lower The Risk
• B. No Relationship
• C. The Higher The IOP, The Higher The Risk Of Glaucoma Development
• D. Risk Is Determined Solely By Age

Answer: (C)

The key idea is that intraocular pressure is a major factor that influences glaucoma risk. When pressure inside the eye is higher, the optic nerve is subjected to greater stress over time, increasing the likelihood of optic nerve damage and subsequent visual field loss. This relationship generally means that higher IOP is associated with a higher risk of developing glaucoma, especially as the duration and magnitude of elevated pressure rise.

However, this isn’t an absolute rule: some people develop glaucoma at normal IOP levels (normal tension glaucoma), and not everyone with high IOP will develop glaucoma. So while higher IOP raises risk, other factors like optic nerve resilience, vascular factors, age, and total exposure to elevated pressure also play important roles.
