Glaucoma, or watery eyes, is one of the most serious eye diseases that can lead to gradual vision loss if not detected and treated early. This disease occurs due to increased pressure inside the eye, which damages the optic nerve responsible for transmitting visual signals to the brain. The danger of glaucoma lies in its silent development, often without noticeable symptoms in its early stages. This makes regular eye exams essential for detection before it permanently affects vision. In this article, we will explore the causes of glaucoma, the symptoms that may indicate its presence, and the latest effective treatment methods that help control the disease and maintain eye health.
What is glaucoma?
Glaucoma, or watery eyes, is a group of diseases that affect the optic nerve and gradually impair vision. It can lead to permanent vision loss if not diagnosed and treated early. This damage often occurs due to increased pressure inside the eye, which damages the nerve fibers responsible for transmitting visual signals to the brain. However, glaucoma can occur even at normal eye pressure levels, making early detection crucial for preserving vision.
The danger of glaucoma lies in its silent development, often without noticeable symptoms in the early stages. This means those affected may not realize they have it until their vision is significantly impacted. For this reason, regular eye exams are recommended, especially for those at higher risk, such as the elderly and those with a family history of the disease. Early diagnosis and appropriate treatment can help slow the progression of the disease and preserve vision for as long as possible.

Causes of Glaucoma
Glaucoma occurs due to damage to the optic nerve, often caused by increased intraocular pressure resulting from impaired fluid drainage. As fluid accumulates inside the eye, the pressure gradually increases, potentially damaging the optic nerve and leading to vision loss. The most prominent factors that increase the risk of developing glaucoma include:
High intraocular pressure due to impaired fluid drainage.
Poor blood flow to the optic nerve.
Genetic factors that increase the risk of developing the disease.
Advancing age, as the likelihood of developing glaucoma increases with age.
Having chronic diseases such as diabetes or high blood pressure.
Severe nearsightedness or farsightedness.
A buildup of iris pigments in the drainage channels, causing blockages.
Congenital eye defects that may lead to high pressure from birth.
Since the disease develops silently in its early stages, regular checkups are essential to detect it before it affects vision irreversibly.

Symptoms of glaucoma
Glaucoma often develops without noticeable symptoms in its early stages, making it difficult to detect until permanent damage to the optic nerve occurs. The effect usually begins in the periphery of the visual field before gradually spreading to the center.
Common symptoms of glaucoma include:
Blurred or cloudy vision.
Blind spots or gradual loss of visual field (tunnel vision).
Seeing colored halos around lights.
Redness of the eye.
Feeling pressure or pain inside the eye.
Frequent headaches.
In acute cases (such as angle-closure glaucoma)
In acute cases, sudden symptoms may appear requiring immediate medical attention, including:
Severe eye pain.
Nausea and vomiting accompanied by eye pain.
Sudden vision loss.
Seeing flashes of light or an increase in floaters.
Because the disease can develop silently, regular eye exams are essential for early detection and to minimize complications.
Types of Glaucoma
Glaucoma varies depending on how it affects the drainage of fluids inside the eye. The most prominent types include:
Open-angle glaucoma: The most common type, it develops slowly due to a gradual blockage of the drainage channels, leading to increased pressure without any noticeable symptoms initially.
Closed-angle glaucoma: A sudden blockage occurs at the drainage angle; This causes a rapid increase in eye pressure and severe symptoms requiring emergency intervention.
Secondary glaucoma: This results from other conditions such as eye infections, injuries, or the use of certain medications, leading to increased pressure inside the eye.
Congenital glaucoma: This affects children from birth due to congenital abnormalities that impact fluid drainage. It requires early treatment to preserve vision.
Early diagnosis and regular follow-up are essential to minimize the disease's impact on vision quality.
Treatment Methods for Glaucoma
Treatment for glaucoma focuses on lowering eye pressure to prevent the problem from worsening. Treatment options include:
Eye drops: These are used to improve fluid drainage or reduce its production. A doctor may recommend more than one type to effectively control pressure.
Oral medications: Such as carbonic anhydrase inhibitors, which reduce intraocular pressure when eye drops alone are insufficient.
Laser treatment: This involves several procedures, such as opening blocked channels or modifying fluid flow within the eye using laser beams.
Microsurgery: This is performed in advanced cases to create a new drainage channel for fluids, helping to permanently reduce pressure.
The appropriate treatment is determined based on the type of glaucoma and the patient's condition. Most patients require regular follow-up appointments to adjust their treatment and maintain eye health.
