Dorzolamide, sold under the brand name Trusopt among others, is a medication used to treat high pressure inside the eye, including in cases of glaucoma. [3] It is used as an eye drop. [3] Effects begin within three hours and last for at least eight hours. [3] It is also available as the combination dorzolamide/timolol. [3] [4]
Of the different types of glaucoma, the most common are called open-angle glaucoma and closed-angle glaucoma. [7] Inside the eye, a liquid called aqueous humor helps to maintain shape and provides nutrients. The aqueous humor normally drains through the trabecular meshwork. In open-angle glaucoma, the draining is impeded, causing the liquid to ...
The crystalline lens inside the human eye has been implicated as a causative factor in many forms of glaucoma. Lens induced glaucomas or Lens related glaucomas are either open-angle or closed-angle glaucomas that can occur due to a neglected advanced cataract (cloudiness of the lens) or a dislocated lens. It is a type of secondary glaucoma.
Exfoliation syndrome: Exfoliation syndrome is a classic cause of secondary open-angle glaucoma, a common symptom of exfoliation syndrome is a cloudy layer on the anterior lens capsule. [2] Aphakic and pseudophakic glaucoma: Aphakic glaucoma is a common side-effect of cataract surgery which causes an increase in IOP. [2]
Acetazolamide, sold under the trade name Diamox among others, is a medication used to treat glaucoma, epilepsy, acute mountain sickness, periodic paralysis, idiopathic intracranial hypertension (raised brain pressure of unclear cause), heart failure and to alkalinize urine.
Dipivefrine, or dipivefrin, also known as epinephrine pivalate and sold under the brand name Propine among others, is a sympathomimetic medication which is used in the treatment of open-angle glaucoma. [2] [3] It is available as a 0.1% ophthalmic solution . [1] [4] Side effects of dipivefrine
Glaucoma medication is divided into groups based on chemical structure and pharmacologic action. The goal of currently available glaucoma therapy is to preserve visual function by lowering intraocular pressure (IOP) in patients that have an increased intraocular pressure.
Inhibition of carbonic anhydrase in the ciliary processes of the eye decreases aqueous humor secretion and thus lowers the intraocular pressure in the anterior chamber, presumably by reducing the rate of formation of bicarbonate ions with subsequent reduction in sodium and fluid transport; this may alleviate the effects of open-angle glaucoma.
