As intraocular pressure increases, how does the risk of glaucoma development change?

Explanation:
Elevated intraocular pressure is a major risk factor for glaucoma. The higher the pressure, and the longer it stays elevated, the more stress is placed on the optic nerve head and retinal nerve fibers, increasing the chance of ganglion cell death over time. This creates a dose‑response relationship: greater IOP generally means a higher likelihood of developing glaucoma. There are exceptions—some people tolerate higher IOP without glaucoma, and glaucoma can occur at normal IOP—but the overall pattern is that increasing IOP raises risk.
