When intraocular pressure increases, as in glaucoma, why does the ciliary muscle's ability to adjust lens curvature to focus on near objects decrease?

💡 Explanation

Elevated intraocular pressure reduces the mechanical compliance of the ciliary muscle because the increased pressure impedes its ability to contract and change the shape of the lens. Therefore, the ability to focus on near objects diminishes, rather than issues with pupil constriction or retinal nerve fiber thickness being the direct cause.
