Glaucoma, a condition characterized by damage to the optic nerve and vision loss, is often caused by high intraocular pressure (IOP). Maintaining a healthy IOP is crucial for optimal blood flow to the optic nerve and can help prevent or slow the progression of glaucoma. However, IOP management may vary from person to person and can change due to environmental and physical factors. It is important to regularly monitor and manage IOP to preserve vision health.
