Differences in pressure between the two eyes are often clinically significant, and potentially associated with certain types of glaucoma, as well as iritis or retinal detachment. Intraocular pressure may become elevated due to anatomical problems, inflammation of the eye, genetic factors, or as a side-effect from medication .
Studies have found a decrease in intraocular pressure to the mid-teens following the procedure, which has a favorable safety profile. [44] [45] The most common complication from Trabectome surgery is bleeding, which can blur vision and take extra time to recover. The surgery site can scar over time and the pressure can go back up.

Ocular hypertension is treated with either medications (eye drops), surgery, or laser. Treatment, by lowering the intraocular pressure, may help decrease the risk of vision loss and damage to the eye from glaucoma. Treatment options include pressure-lowering 'antiglaucomatous' eye drops, surgery, and/or laser eye surgery. [4]
Glaucoma is a group of diseases affecting the optic nerve that results in vision loss and is frequently characterized by raised intraocular pressure (IOP). There are many glaucoma surgeries, and variations or combinations of those surgeries, that facilitate the escape of excess aqueous humor from the eye to lower intraocular pressure, and a few that lower IOP by decreasing the production of ...
Conversely, optic nerve damage may occur with normal pressure, known as normal-tension glaucoma. [27] In case of above-normal intraocular pressure, the mechanism of open-angle glaucoma is believed to be the impeded exit of aqueous humor through the trabecular meshwork, while in closed-angle glaucoma, the iris blocks the trabecular meshwork.

It is an important test in the evaluation of patients at risk from glaucoma. [1] Most tonometers are calibrated to measure pressure in millimeters of mercury , with the normal eye pressure range between 10 and 21 mmHg (13–28 hPa).
