About Glaucoma
Glaucoma is a chronic eye disease in which optic nerve fibers are damaged due to increased intraocular pressure (IOP), and without treatment it can progress to permanent vision loss. It is one of the leading causes of preventable blindness worldwide, and nearly half of patients are unaware they have it.
Pressure elevation usually develops slowly; therefore glaucoma may progress for a long time without symptoms. Regular eye examinations, optic nerve head evaluation, and visual field testing help detect the disease early.
What is Glaucoma (Eye Pressure)?
The eye continuously produces a fluid called aqueous humor that supports ocular nutrition. If resistance increases while this fluid drains through the trabecular meshwork, intraocular pressure rises. Elevated IOP compresses the fibers nourishing the optic nerve and causes irreversible damage. Depending on glaucoma type, this process may be slow or sudden.
Symptoms
Although glaucoma often progresses silently, sudden symptoms may occur, especially in angle-closure types:
- Severe headache and eye pain
- Blurring or narrowing in the visual field
- Seeing colored halos around lights
- Nausea and vomiting
- Redness and a feeling of hardness in the eye

Glaucoma types
Open-angle glaucoma
This is the most common type of glaucoma. Due to increased resistance in the trabecular meshwork, fluid outflow slows and intraocular pressure rises over months to years. It is initially painless and can damage the optic nerve without obvious symptoms. Regular measurements and OCT evaluations are essential.
Angle-closure glaucoma
Because the angle between the iris and cornea is narrow, fluid outflow can suddenly become blocked. Eye pain, headache, and halos around lights develop rapidly. In acute attacks, eye pressure rises sharply and urgent treatment is required.
Causes and Risk Factors
Of glaucoma temel cause, eye within produced fluid yeterince drain is inadequate drainage. Bununla together with bazi in some individuals risk factors eye intraocular pressure artisi for strong triggers:
- Family history of glaucoma and genetic predisposition
- Hyperopia (for angle-closure glaucoma) or myopia (for open-angle glaucoma)
- High or low systemic blood pressure
- Thinner-than-normal corneas
- Eye injuries or previous surgeries
- Age over 40
- Long-term steroid use
- Systemic diseases such as diabetes and migraine
- African or Hispanic ancestry
What should eye pressure be?
In healthy individuals, ideal intraocular pressure is generally in the 12-18 mmHg range. Because values can fluctuate throughout the day, a single measurement is not diagnostic on its own. In suspected glaucoma, tonometry, pachymetry, and visual field tests are used for regular follow-up and individualized target pressure setting.
Treatment approaches
Glaucoma in treatment amac optic nerve korumak for eye intraocular pressure dusurmektir. Treatment plan glaucoma type and patient risk profile according to kisisellestirilir:
- Eye drops: Prostaglandin analogs, beta-blockers, or carbonic anhydrase inhibitors are prescribed to reduce intraocular pressure.
- Laser procedures: Selective laser trabeculoplasty (SLT) or laser iridotomy controls pressure by improving fluid drainage.
- Surgical options: Trabeculectomy, drainage implants, or minimally invasive glaucoma surgery are applied in resistant cases.
- Lifestyle and follow-up: Regular measurements, medication adherence, and control of accompanying systemic diseases are integral parts of treatment.
