Open-Angle Glaucoma: The Silent Thief of Sight
Open-angle glaucoma is the most common type of glaucoma. It often progresses without noticeable symptoms, earning it the nickname "the silent thief of sight." In this condition, the angle between the iris (colored part of the eye) and cornea (clear front part of the eye) is open, but the fluid inside the eye drains slowly, causing a gradual increase in eye pressure.
 
Why is open-angle glaucoma dangerous?
 
Silent nature: In the early stages, open-angle glaucoma often has no symptoms.
Gradual progression: The increased eye pressure gradually damages the optic nerve, eventually leading to vision loss.
Irreversible damage: Once damaged, optic nerve cells cannot regenerate, making any damage permanent.
 
Risk factors for open-angle glaucoma
 
Age: Older adults are at higher risk.
Family history: A family history of glaucoma increases the risk.
Race: Certain races, such as African Americans, have a higher risk.
Diabetes: People with diabetes are at increased risk.
High blood pressure: High blood pressure can damage the optic nerve.
Eye injuries: Eye injuries can increase the risk of developing glaucoma.
 
Symptoms of open-angle glaucoma
In the early stages, open-angle glaucoma typically has no symptoms. As the disease progresses, symptoms may include:
 
Blurred vision, especially in peripheral vision
Halos around lights
Decreased night vision
 
Diagnosing open-angle glaucoma
Early detection of open-angle glaucoma is crucial. An ophthalmologist will use the following tests to make a diagnosis:
 
Intraocular pressure measurement: To measure the pressure inside the eye
Gonioscopy: To examine the angle between the iris and cornea
Perimetry: To assess your field of vision
Optic nerve imaging: To evaluate damage to the optic nerve
 
Treating open-angle glaucoma
The goal of treatment is to lower eye pressure and prevent further vision loss. Treatment options may include:
 
Medications: Eye drops to lower eye pressure
Laser surgery: To create a new drainage pathway for fluid in the eye
Traditional surgery: In cases where medications and laser treatments are ineffective
 
Importance of regular eye exams
Regular eye exams are crucial for early detection and treatment of open-angle glaucoma. This is especially important for those with a family history of glaucoma or who fall into high-risk groups. Open-angle glaucoma is a serious condition that can lead to blindness if left untreated. Early detection and treatment are essential.

What causes corneal ulcers?

What causes corneal ulcers?

A corneal ulcer typically occurs due to an infection in the corneal tissue. However, other conditions such as severe dry eye can also lead to the formation of a corneal ulcer. It's important to understand that healing from this condition may take several weeks or even months. Please be patient and follow your doctor's treatment plan closely.

Endophthalmitis: A Serious Eye Infection

Endophthalmitis: A Serious Eye Infection

Endophthalmitis is an infection of the clear fluids inside your eye. This infection can cause serious damage because it directly affects the tissues inside your eye. That's why it's important to prevent it, and if it does happen, to diagnose and treat it quickly. Endophthalmitis is a serious condition that can lead to vision loss if not treated promptly. If you experience any symptoms of endophthalmitis, seek medical attention immediately.

Discover more about PRK eye surgery

PRK, or photorefractive keratectomy, is a type of laser eye surgery used to correct refractive errors such as nearsightedness, farsightedness, and astigmatism. Due to its proven safety profile, PRK is often considered the preferred method for correcting refractive errors.

Key Points you know about refractive surgeries

Refractive surgery is a medical procedure that reshapes the cornea of the eye using lasers or other surgical tools to correct refractive errors. By doing so, the need for glasses or contact lenses is minimized, and individuals can see distant and near objects clearly.

A Silent Threat, It Is Time to Action
World Hepatitis Day 2024

A Silent Threat, It Is Time to Action

The World Health Organization has designated July 28th as World Hepatitis Day to raise awareness about this disease, encourage vaccination, promote early diagnosis, and facilitate effective treatment for hepatitis. Early detection of hepatitis is crucial as prompt treatment can prevent the disease from progressing to cirrhosis or liver cancer.

Glaucoma: Early Detection, Lifelong Vision
World Glaucoma Week

Glaucoma: Early Detection, Lifelong Vision

The primary cause of glaucoma is increased pressure inside the eye. This pressure, known as intraocular pressure, damages the optic nerve. One of the most insidious aspects of glaucoma is that it often progresses without noticeable symptoms in its early stages. Early detection is crucial in managing glaucoma. While there is no cure for glaucoma, early detection and treatment can significantly slow down or even stop the progression of the disease. Regular eye exams are essential, especially for those at higher risk. Farabi Hospital's ophthalmology department is renowned for delivering cutting-edge treatments and unparalleled care to patients with glaucoma.
