Glaucoma is one of the leading causes of irreversible blindness worldwide, and open-angle glaucoma is the most common type. Because it develops slowly and often without noticeable symptoms, many people are unaware they have the condition until permanent vision loss has already occurred. This is why it is commonly known as the “silent thief of sight.
Early diagnosis and proper treatment can significantly slow the progression of glaucoma and help preserve your vision. If you are over 40, have a family history of glaucoma, or suffer from diabetes or high blood pressure, regular eye examinations are essential. Consulting an experienced glaucoma specialist like Dr. Puja Sheth in Ahmedabad can help detect the disease before it causes permanent damage.
What Is Open-Angle Glaucoma?
Open-angle glaucoma is a chronic eye condition that gradually damages the optic nerve, which carries visual information from the eye to the brain. Although the drainage angle between the iris and cornea remains open, the eye’s drainage system does not function efficiently. This causes eye pressure (intraocular pressure) to rise slowly over time, damaging the optic nerve.
Since the disease progresses gradually, most patients experience no pain or obvious warning signs during the early stages.
Symptoms of Open-Angle Glaucoma
One of the biggest challenges with open-angle glaucoma is that symptoms often appear only after significant vision loss has occurred. However, some warning signs may include:
Gradual Loss of Peripheral Vision
The earliest symptom is usually a slow reduction in side (peripheral) vision. Patients may not notice this until daily activities become difficult.
Blurred Vision
Some people experience mild or intermittent blurred vision, especially as optic nerve damage progresses.
Difficulty Seeing in Low Light
Night driving or moving around in dimly lit environments may become increasingly difficult.
Tunnel Vision
In advanced stages, vision becomes restricted, leaving only central vision while side vision disappears.
Unlike angle-closure glaucoma, open-angle glaucoma rarely causes severe eye pain or redness, making routine glaucoma screening extremely important.
What Causes Open-Angle Glaucoma?
Although the exact cause is not always known, several factors increase the risk of developing open-angle glaucoma.
Increased Eye Pressure
High intraocular pressure is the most common risk factor. When fluid inside the eye cannot drain efficiently, pressure builds up and damages the optic nerve.
Age
People over the age of 40 have a higher risk, with the likelihood increasing further after age 60.
Family History
Having a close family member with glaucoma significantly increases your chances of developing the condition.
Diabetes and High Blood Pressure
These medical conditions can affect blood circulation to the optic nerve, increasing glaucoma risk.
Thin Corneas
Individuals with thinner-than-average corneas may be more susceptible to optic nerve damage.
Long-Term Steroid Use
Extended use of steroid medications, especially steroid eye drops, may raise eye pressure and contribute to glaucoma development.
How Is Open-Angle Glaucoma Diagnosed?
Regular eye examinations are the best way to detect glaucoma before vision loss occurs. During a comprehensive glaucoma evaluation, your ophthalmologist may perform several diagnostic tests, including:
- Eye pressure measurement (Tonometry)
- Optic nerve examination
- Visual field (Perimetry) test
- OCT (Optical Coherence Tomography) scan
- Corneal thickness measurement (Pachymetry)
- Gonioscopy, when required
These advanced tests help evaluate the health of the optic nerve and determine whether glaucoma is present.
At her eye hospital in Ahmedabad, Dr. Puja Sheth uses modern diagnostic technology to detect glaucoma at its earliest stages and create personalized treatment plans for each patient.
Treatment Options for Open-Angle Glaucoma
Although glaucoma cannot be cured, early treatment can effectively control eye pressure and slow disease progression.
Glaucoma Eye Drops
Prescription eye drops are usually the first line of treatment. They reduce eye pressure by either decreasing fluid production or improving drainage.
Laser Treatment
Laser procedures such as Selective Laser Trabeculoplasty (SLT) can improve drainage and lower eye pressure in suitable patients.
Minimally Invasive Glaucoma Surgery (MIGS)
For patients requiring surgical intervention, MIGS offers smaller incisions, quicker recovery, and fewer complications compared to traditional surgery.
Trabeculectomy or Tube Shunt Surgery
In advanced glaucoma cases, procedures like trabeculectomy or glaucoma drainage device implantation may be recommended to control eye pressure when medications and laser treatments are insufficient.
Can Open-Angle Glaucoma Be Prevented?
While glaucoma cannot always be prevented, early detection greatly reduces the risk of severe vision loss. You can protect your eyesight by:
- Scheduling regular eye examinations after age 40
- Managing diabetes and high blood pressure
- Following prescribed glaucoma medications
- Avoiding unnecessary steroid use without medical supervision
- Maintaining a healthy lifestyle with regular exercise and a balanced diet
- Keeping all follow-up appointments with your eye specialist
Routine glaucoma screening remains the most effective way to identify the disease before symptoms appear.
