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]
Over many years, glaucoma has been defined by an intraocular pressure of more than 20 mm Hg. Incompatible with this (now obsolete) definition of glaucoma was the ever larger number of cases that have been reported in medical literature in the 1980s and 1990s who had the typical signs of glaucomatous damage, like optic nerve head excavation and thinning of the retinal nerve fiber layer, while ...
After two years researchers found that vision and quality of life are similar in both treatments. At the same time eye pressure was lower in people who underwent surgery and in the long-run surgery is more cost-effective. [114] [115] The LiGHT trial compared the effectiveness of eye drops and selective laser trabeculoplasty for open angle glaucoma.

Intraocular pressure is determined by the production and drainage of aqueous humour by the ciliary body and its drainage via the trabecular meshwork and uveoscleral outflow. The reason for this is because the vitreous humour in the posterior segment has a relatively fixed volume and thus does not affect intraocular pressure regulation.
After a long holiday season indulging in sweet treats and perhaps a few too many spirits, January can be a great time to reset and return to healthy habits. Dry January, a health campaign that ...
As the probe bounces against the cornea and back into the device, it creates an induction current from which the intraocular pressure is calculated. The device is simple and easy to use and self-use versions are available. It is portable, does not require the use of eye drops and is particularly suitable for children and non-cooperative ...
Chronic intermittent hypoxia impairs endothelial function, reducing nitric oxide production, which leads to vasoconstriction and reduced blood flow to the optic nerve head. Additionally, fluctuations in pressure within the thoracic cavity during apnea episodes can alter intraocular pressure, affecting the blood supply to the optic nerve head .
