Intraocular pressure (IOP) is the fluid pressure inside the eye. It is a critical factor in maintaining the shape of the eye and creating a healthy environment for the optic nerve and retina. Abnormal intraocular pressure is often associated with eye conditions such as glaucoma, which can lead to vision loss if left untreated. Research in this area focuses on understanding the factors that influence IOP, developing new methods for measuring it accurately, and exploring potential treatments to regulate it effectively. Studies in this field aim to improve the diagnosis and management of eye diseases related to intraocular pressure, ultimately helping to preserve and restore vision in patients.
