Glaucoma Evaluation & Treatment
Protect Your Vision from Glaucoma | Akshaya Nethralaya
Glaucoma is a group of eye diseases that damage the optic nerve, often caused by elevated intraocular pressure (IOP). If left untreated, glaucoma can lead to permanent vision loss. At Akshaya Nethralaya, we offer a complete glaucoma evaluation and effective treatment options to protect your vision and prevent further damage. Early detection is crucial, as the disease may progress without noticeable symptoms in its early stages.
What Is Glaucoma?
Glaucoma is a condition where the pressure inside the eye rises to a level that can damage the optic nerve, which transmits visual information from the retina to the brain. There are two primary types of glaucoma:
Open-Angle Glaucoma
The most common form, where the eye’s drainage canals gradually become blocked, leading to an increase in eye pressure. It typically develops slowly and can cause gradual vision loss, often without noticeable symptoms.
Angle-Closure Glaucoma
A less common but more serious form where the drainage angle in the eye becomes blocked suddenly, causing a rapid increase in intraocular pressure and severe symptoms like pain and blurred vision. This is considered a medical emergency.
Normal-Tension Glaucoma
In this type, damage to the optic nerve occurs even though the eye pressure remains within the normal range. The cause is often related to poor blood flow to the optic nerve.
Congenital Glaucoma
A rare condition where glaucoma is present at birth or develops in early childhood due to an abnormality in the eye’s drainage system.
Glaucoma Evaluation – Comprehensive Eye Exam
A glaucoma evaluation at Akshaya Nethralaya involves a thorough eye examination to detect any signs of the disease. Our evaluation includes:
1. Intraocular Pressure (IOP) Test (Tonometry)
This test measures the pressure inside your eye. Elevated eye pressure is a key risk factor for glaucoma.
2. Visual Field Test (Perimetry)
This test checks for areas of vision loss in the peripheral (side) vision, a common symptom of glaucoma.
3. Optic Nerve Evaluation
We examine the optic nerve for signs of damage. This can be done using specialized imaging techniques like OCT (Optical Coherence Tomography).
4. Gonioscopy
This test helps evaluate the angle of the eye to determine whether the drainage angle is open or closed, which helps identify the type of glaucoma.
5. Pachymetry
This measures the thickness of the cornea, which can affect the accuracy of pressure readings and provide more information for diagnosis.
Glaucoma Treatment – Managing and Controlling Eye Pressure
While glaucoma cannot be cured, it can be effectively managed to prevent further vision loss. Treatment options include:
1. Medications (Eye Drops or Oral Medication)
The first line of treatment for glaucoma usually involves eye drops that help lower intraocular pressure by reducing fluid production or improving fluid drainage. Oral medications may also be prescribed for additional support.
2. Laser Treatment
- Laser Trabeculoplasty: This is often used for open-angle glaucoma. The procedure helps improve the drainage of fluid from the eye, reducing intraocular pressure.
- Laser Iridotomy: For angle-closure glaucoma, a small hole is created in the iris to help fluid flow more easily within the eye.
- Selective Laser Trabeculoplasty (SLT): A non-invasive laser procedure that targets specific parts of the drainage system to reduce eye pressure.
3. Surgery
If medications and laser treatments do not provide adequate control, surgery may be needed to create a new drainage channel for fluid or to implant a device to help reduce eye pressure.
- Trabeculectomy: A surgical procedure to create a new drainage channel to lower intraocular pressure.
- Glaucoma Drainage Devices: Implantation of a small device to help the eye drain fluid more effectively.
Why Early Detection and Treatment Are Important
Glaucoma is often called the “silent thief of sight” because it can develop slowly without symptoms until significant vision loss occurs. Early detection and timely treatment are crucial to prevent irreversible damage to the optic nerve. Regular eye exams are important, especially for individuals at higher risk of glaucoma:
- Family history of glaucoma
- Age over 40
- Chronic eye conditions or injuries
- Use of corticosteroids
- Diabetes or high blood pressure
Tips for Managing Glaucoma
Always use prescribed eye drops as directed by your doctor and attend follow-up appointments.
Even if you don’t have symptoms, regular eye exams are essential for detecting glaucoma early.
Wear protective eyewear to prevent eye injuries, which can increase the risk of glaucoma.
Maintain a healthy diet and regular exercise to reduce overall health risks, including those related to eye health.
Who Should Consider Glaucoma Evaluation?
- Anyone over the age of 40 should have regular glaucoma screenings, especially if you have a family history of the disease.
- People with elevated intraocular pressure or those diagnosed with early-stage glaucoma should have regular evaluations.
- Those with symptoms of vision loss such as blurred vision, halos around lights, or difficulty seeing at night.
- Individuals with other health conditions, such as diabetes or hypertension, which increase the risk of developing glaucoma.
