Glaucoma Unit

The clinic evaluates and treats patients with Glaucoma and other diseases characterised by increased pressure in the eye and/or glaucomatous atrophy of the optic nerve.  It also serves as a large referral centre for the treatment of Congenital Glaucoma, a rare condition with increased eye pressure and corneal enlargement present at birth or during the first few months of life. Patients of all ages, from new-borns to the elderly are being treated.

Glaucoma Clinics at all Aravind centres are well equipped with the latest diagnostic and therapeutic modalities to combat blindness due to the disease. The centre at Tirunelveli is recognised as a Centre of Excellence with a commitment to enhancing quality of patient care and education of ophthalmologists in early diagnosis and therapy.

Glaucoma Treatment and Surgery services are available at Mazharul Haque BNSB Eye Hospital, Chandpur. The Screening Services also available in PEC, Vision Center and Screening Eye Camps.

Glaucoma Screening Statistics

Glaucoma is a common eye condition where the optic nerve, which connects the eye to the brain, becomes damaged. It’s usually caused by fluid building up in the front part of the eye, which increases pressure inside the eye. Glaucoma can lead to loss of vision if it’s not diagnosed and treated early.


Diagnosis and Treatment of Glaucoma

The clinic handles Primary Glaucomas, which are largely inherited, in addition to Secondary Glaucomas caused by trauma, inflammation, Diabetes, Retinal Vascular Disease and hypermature cataracts. Deviations from normal retinal nerve fibre thickness are the earliest structural changes in persons with glaucoma.

Knowledgebase about Glaucoma

There are two main types of glaucoma: Open Angle and Angle Closure.

If you have glaucoma, your symptoms will depend on the type.

Open Angle:

There are very few symptoms in the early stages. Your side (peripheral) vision will slowly get worse.

Angle Closure:

You may have sudden, severe symptoms, like:

  • Dull, aching eye pain
  • Headache
  • Eyebrow ache
  • Halos or colored rings around lights

At later stages, both types may cause symptoms, such as:

  • Intense eye pain
  • Eye redness
  • Watering eyes
  • Blurry vision & vision loss

If you have sudden changes in vision, see a doctor right away. It may not be glaucoma, but it is important to get it checked.

Remember: once your vision is lost, it cannot be regained. However, early treatment can prevent future vision loss! Regular visits to an eye doctor are the BEST way to save your eyes from blindness.

Glaucoma can also occur in newborns and children who have undergone cataract surgery at an early age.

Signs seen in newborns are:

  • Large cornea, opacified cornea
  • Watering of eyes
  • Child withdraws from light / buries his head to prevent exposure to light

Older children may not show any signs

Glaucoma cannot be cured. Treatment cannot reverse vision loss, but it can stop your vision from getting worse. That is why it is so important to treat glaucoma in the early stages.  Your doctor will choose the best treatment option for you, depending on your specific case. In most cases, you will need to control your eye pressure for the rest of your life. Your doctor will create an individualized plan to keep your eyes healthy. This plan will depend on the type of glaucoma you have. For the best results, follow your treatment plan . Remember – once your vision is lost to glaucoma, it cannot be restored. The earlier you start treatment, the better the outcome!

With treatment, most glaucoma cases can be controlled. However, in a few cases, vision cannot be saved. For those patients, Vision Rehabilitation may teach patients how to adjust to their new lives with low vision.

The three main types of treatment for glaucoma are:

  • Eye Drops
  • Laser Treatment
  • Surgery

Eye Drops:

For most patients, eye drops are the most important part of treatment. They work by reducing the eye pressure. There are different types. In fact, some patients must take more than one type of eye drop for the best results.

How they work: Eye drops reduce eye pressure by lowering the amount of fluid in the eye. They may reduce the amount of fluid made by the eye, or, they may improve the eye’s drainage channels, so that fluid exits the eye more easily.

Side Effects: Eye drops may irritate the eye. If you have other eye conditions, you may not be able to use the drops. You may also experience eye swelling, itchy eyes, red eyes, and an abnormal heart rate.

Using the Eye Drops: Your doctor and counselor will work with you to develop a detailed treatment plan. This plan MUST be followed as closely as possible. Your vision is at risk if you stop following the treatment plan. To apply the eye drops:

    1. Gently pull down the lower eye lid with a finger.
    2. Hold the eye drop bottle over your eye at a slight tilt.
    3. Squeeze the eye drop bottle very slightly so a single eye drop falls into the space behind your lower lid.
    4. Close your eye. Keep it closed for a few minutes.
    5. If you use more than one type of eye drop, wait at least 5 more minutes before applying the second type.

Laser Treatment:

Laser treatment may be another option for some glaucoma patients. The type of laser therapy will depend on the type of glaucoma that you have.

Laser Trabeculoplasty: This laser is used to treat open angle glaucoma. It opens the eye’s fluid-draining channels. This reduces eye pressure because it lets the fluid exit the eye. Laser trabeculoplasty is done in patients who need to reduce their eye pressure to prepare for glaucoma surgery. However, it is a temporary solution. It is not an end treatment.

Peripheral Iridotomy: All patients who either 1) show signs of angle closure or 2) have been diagnosed with angle closure glaucoma MUST get peripheral iridotomy. This minimizes the risk of glaucoma and vision loss. The procedure uses a high-energy laser beam to create a small hole in the iris. This allows fluid to drain away from the eye.

What to Expect: About Laser Treatment

  • You will be given a local anesthetic. This means you will be awake, but should not feel pain.
  • You may need to go for laser treatment many times before you see any effects.
  • Some patients may still need to use eye drops after laser treatment.

For patients with severe refractory glaucoma, there may be no chance of improving vision. In these cases, a special diode laser is used to safely lower the eye pressure and reduce the patient’s pain.


Surgery is performed in patients who have advanced/progressive glaucoma, have a coexisting significant cataract, or are not responding to medication.
