Glaucoma
Glaucoma
Treatment: Most glaucoma treatments are based on controlling intraocular pressure, which can damage the optic nerve. Eye drops are often the first choice before surgical treatment, which can effectively reduce intraocular pressure and prevent eye damage. Lowering intraocular pressure with the help of other methods such as laser therapy-surgery or a combination of these methods is also possible depending on the type and severity of the disease selected by the attending physician.
It is a type of eye disease in which the optic nerve, which is responsible for transmitting visual messages to the brain, is gradually destroyed and as a result causes the gradual loss of vision and blindness. Congestion of the aqueous humor of the eye.
The rate of this disease is higher in people over 40 years old and increases with age. Intraocular pressure depends on the amount of aqueous humor production and secretion (it circulates between the iris and the lens of the eye and nourishes the cornea and lens), the resistance of the aqueous humor movement paths, as well as the venous pressure in the veins on the sclera that drain into the ciliary vein. . In a situation where there is a proper balance between aqueous humor production and drainage, the intraocular pressure is between 10-21 mmHg. When the movement flow of aqueous humor faces an obstacle, the intraocular pressure increases. Glaucoma may go undiagnosed in people with thin corneas because intraocular pressure is erroneously measured due to thin corneas.
Risk factors in glaucoma:
History of glaucoma in the family, thin cornea, old age, diabetes, cardiovascular disease, migraine syndromes, myopia, eye injuries, history of long-term use of topical and systemic corticosteroids.
Types of glaucoma:
Acute angle-closure glaucoma
Chronic or primary open-angle glaucoma
Acute angle-closure glaucoma and primary open-angle glaucoma, which cause the grade of aqueous humor disorder.
Symptoms of Glaucoma: Unfortunately, some types of glaucoma can have no symptoms until the final stages of the disease, and when a person realizes his disease, the disease has destroyed the fibers of his optic nerve and his vision has severely and irreversibly decreased. . Therefore, early detection of glaucoma and timely initiation will be the main key in preventing the progression of the disease and reducing the patient’s vision. In a small group of patients, especially in older age, the disease may start acutely and suddenly with symptoms such as pain and redness of the eyes, vision loss, headache with nausea and vomiting. Glaucoma diagnosis, intraocular pressure measurement, tonometry, eye angle examination or kinoscopy, optic nerve head examination, visual field examination or perimetry
