Glaucoma

What is glaucoma?

Glaucoma is a group of eye diseases that cause damage to the optic nerve, the nerve that transmits visual signals from the eye to the brain. Optic nerve damage is usually caused by high intraocular pressure, the fluid that nourishes the eye and maintains its shape.

Types of glaucoma:

• Open-angle glaucoma: It is the most common type of glaucoma. It develops slowly and usually causes no symptoms in the early stages.
• Angle-closure glaucoma: occurs when fluid drainage in the eye is partially or completely blocked. This condition can occur suddenly and cause severe eye pain, redness, nausea, and vomiting.
• Other types of glaucoma: There are other, less common types of glaucoma, such as congenital glaucoma, which affects newborns, and pigmentary glaucoma, which causes pigment accumulation in the eye.

Glaucoma symptoms:

• There are no symptoms in the early stages of open-angle glaucoma
• In the late stages,

Causes of glaucoma:
• High intraocular pressure is the most common cause of glaucoma.

Glaucoma treatment:
• Glaucoma treatment aims to lower intraocular pressure and prevent further damage to the optic nerve.
• Treatment options may include:
• Eye drops: Eye drops help lower eye pressure by reducing the production of fluid in the eye or
• Improve its drainage.
• Oral medications: Oral medications may be used if eye drops are not effective.
• Surgery: Surgery may be necessary if other treatments don't work.
• Laser treatment: Laser treatment can be used to create a new passage for fluid drainage in the eye.
