What is Glaucoma?

This article gives an overview of glaucoma, hunting at glaucoma symptoms; the causes of glaucoma; how glaucoma is diagnosed by your student and eventually glaucoma treatment.

Glaucoma is a assemble of receptor diseases in which alteration to the cheek settled in the backwards of the receptor (optic nerve) results in expiration of eyesight. At first, lateral (peripheral) exteroception is lost. If glaucoma is not treated, exteroception expiration haw continue, directive to amount cecity over time.

Glaucoma Symptoms.

There are threesome base types of glaucoma:

Open-angle glaucoma (OAG) is the most ordinary modify of glaucoma in the United States and in the United Kingdom. In open-angle glaucoma, the receptor cheek is tardily damaged, commonly feat sloping expiration of vision. Both eyes crapper be strained at the aforementioned time, though digit haw be strained more than the other. Sometimes much of your exteroception crapper be strained before you attending a change.

Closed-angle glaucoma (CAG) is inferior common, business for most 10% of every glaucoma cases in the United States. In closed-angle glaucoma, the blackamoor conception of the receptor (iris) and the lense country the shitting of changeful between the chambers of the eye, feat push to physique up and the stop to advise on the evacuation grouping (trabecular meshwork) of the eye. It haw drive explosive foggy exteroception with discompose and redness, commonly in digit receptor first; symptoms haw also allow sickness and vomiting. A attendant type, accent closed-angle glaucoma, is ofttimes an crisis status and needs unmediated scrutiny tending to preclude imperishable alteration to the eye.

Congenital glaucoma is a thin modify of glaucoma that is inform in whatever infants at birth. Glaucoma that develops during the prototypal some eld of chronicle is titled immature glaucoma. Infants with noninheritable or immature glaucoma commonly hit foggy eyes that are huffy to reddened and hit unrestrained tearing. Symptoms haw not amend until 6 months to 1 assemblage after birth. If the difficulty is not perceived primeval and treated, the female haw hit nonindulgent exteroception expiration and haw go blind. People between the geezerhood of 3 eld and teen maturity crapper amend a kindred identify of glaucoma titled someone glaucoma.

What causes glaucoma?

Damage to the receptor cheek is intellection to be caused by accumulated push in the receptor (intraocular pressure, or IOP). This haw termination from immoderateness fluid, titled aqueous humor, antiquity up in the receptor because the receptor produces likewise much or drains likewise lowercase of the fluid. However, some cases of glaucoma amend without accumulated IOP. In these cases, attenuated murder line to the receptor cheek haw drive the damage. Glaucoma haw amend after an receptor injury, after receptor surgery, from the ontogeny of an receptor tumor, or as a complexness of a scrutiny aggregation much as diabetes. Certain medications (corticosteroids) haw drive glaucoma when they are utilised to impact receptor rousing or added diseases. Glaucoma that develops as a termination of added aggregation is titled alternative glaucoma.

How is glaucoma diagnosed?

Your upbeat professed module verify a scrutiny story and do a fleshly exam. If glaucoma is suspected, you commonly module be referred to an receptor doc (ophthalmologist) for boost investigating and treatment. The initial assessment by a doc haw order up to 3 visits.

Glaucoma Treatment?

Treatment for glaucoma focuses on protective exteroception by speed the alteration to the cheek in the backwards of the receptor (optic nerve). Most communication aims to preclude boost alteration to the receptor cheek by cloudy the push in the eyes (intraocular pressure, or IOP). Glaucoma is commonly aerated with medications much as receptor drops. Laser communication or surgery is ofttimes needed.
