Primary Open-Angle Glaucoma: The Importance of Raising Awareness

Glaucoma is the second leading cause of blindness globally, but it is surrounded by many mysteries that have not yet been solved by researchers. In addition, the general public does not fully understand the dangers of glaucoma. "It is estimated that over 2 million Americans are suffering from glaucoma, but only half of them know that it is suffering from glaucoma" (Glaucoma Facts, 2013, paragraph 8 ). Glaucoma is a disorder in which the continuous pressure of the optic nerve damages it and may cause loss of vision ("What is glaucoma?", N. D.). Glaucoma is complicated and not very famous.

Primary open-angle glaucoma, the most common form of glaucoma, develops slowly, usually without symptoms. Many people do not know that they are sick before they experience serious sight loss. Initially, glaucoma affects peripheral or lateral vision, but it may promote central vision loss. If it is left untreated, glaucoma may cause the eyesight of both eyes to be significantly lost and even cause blindness. A less common type of glaucoma, acute angle-closure glaucoma usually occurs suddenly due to a sharp rise in intraocular pressure. Symptoms may include severe eye pain, nausea, redness of eyes, halo or colored circles around the light, and blurred vision. This is a serious emergency situation where vision loss can occur soon; see your optometrist soon

The primary open-angle glaucoma is a time when the visual field is gradually lost due to the damage of the optic nerve. This is related to elevated intraocular pressure. Although not all intraocular pressure rises beyond normal levels for all people with open primary angle glaucoma, further reduction in intraocular pressure has been shown to hinder progress even in these cases. Diagnosis is done by finding cupping of the optic nerve. Prostaglandin agonists act by opening the uveoscleral channel. Beta blockers such as timolol act by reducing the formation of moisture. Carbonic anhydrase inhibitors reduce the formation of bicarbonate bicarbonate in the eye, thereby reducing the formation of aqueous humor. A parasympathetic analog is a drug that acts on trabecular efflux by opening the passageway and contracting the pupil. The alpha 2 agonist (bronidine, ampidine) reduces body fluid production (by suppressing AC) and increases drainage.

Primary open angle glaucoma (also known as primary glaucoma, chronic glaucoma) is a slow occlusion that induces the flow tube, causing an increase in intraocular pressure and causing optic nerve damage. This is manifested by gradual loss of visual acuity beginning with loss of visual acuity but eventually losing sight if left untreated. This is the most common type of glaucoma, accounting for 90% in the United States and few in Asian countries. Attacks are slow and painless, blindness is gradual and irreversible.
