Final answer:
If a blockage occurs in the trabecular meshwork, it causes a build-up in intraocular pressure (IOP), potentially leading to glaucoma, a condition that can cause permanent damage to the optic nerve and loss of vision.
Step-by-step explanation:
If a blockage occurs in the trabecular meshwork, intraocular pressure (IOP) builds up, potentially causing a serious condition known as glaucoma. Intraocular pressure is essential for maintaining the shape of the eye, and normal IOP ranges from about 12.0 to 24.0 mm Hg. However, when fluid circulation in the eye is impeded, IOP can rise significantly, sometimes reaching up to 85.0 mm Hg, which can cause permanent damage to the optic nerve. This increased pressure in the eye can lead to the deterioration of vision and eventually blindness if not managed properly.
It's important to note that pressures in the body, such as spinal and skull pressures, bladder pressure, and pressures in the skeletal system, can also impact overall health, but they are distinct from the intraocular pressure associated with the eye.
Individuals over 40 should have their intraocular pressure tested regularly since they are at the greatest risk of developing glaucoma. Detection of high IOP can be done through various methods, including applying force to the anesthetized eye or using a noncontact approach with a puff of air. Early detection of high intraocular pressure can lead to effective control of the condition and prevention of more severe outcomes.
