Glaucoma is the leading causes of irreversible blindness worldwide. In India alone, it affects around 12 million people. Glaucoma is a treatable disease that needs early detection as the damage is not reversible. The treatment can include medicines, laser or surgery. The Himalayan Eye Institute offers comprehensive Glaucoma diagnosis & treatment by trained Glaucoma specialists.

What is Glaucoma?

Glaucoma, otherwise known as “Kala Motia” is an eye disease in which there is an increase in pressure inside the eye. Just as some people have high blood pressure, in the same way a glaucoma patient has high eye pressure. If the eye pressure remains high for a long time it damages the optic nerve which carries the light sense from the eye to the brain. This damage to the nerve is irreversible and leads to permanent and incurable blindness. Glaucoma is the second leading cause of blindness in the world with 70 to 105 million people affected worldwide (WHO).

Glaucoma is often referred to as a “silent thief of vision” as it can strike without any symptoms. However, some glaucoma patients may suffer symptoms like:

  • Severe eye pain in case of angle-closure glaucoma
  • Blurred vision
  • Frequent changes of reading glasses

Everyone is at risk of getting affected by Glaucoma. But certain risk factors for the disease are:

  • High intraocular pressure
  • Age – risk increases with age, especially those beyond 40 years of age
  • Heredity – Primary open-angle glaucoma affects those with a family history of glaucoma
  • Ethnicity – Glaucoma is common among Asians, Africans, Americans, and Hispanics.
  • Sustained eye injury – in such cases, glaucoma can occur immediately after the injury or even in later years
  • High myopia (nearsightedness)
  • Diabetes
  • Thyroid disease
  • Hypertension
  • Steroids intake

How is glaucoma treated?

Glaucoma cannot be cured, but it can be controlled. As damage to nerve caused by glaucoma cannot be reversed, the aim of the treatment is to prevent or reduce further damage to the optic nerve. The first step to do that is to lower the eye pressure. The three modalities of treatment are:-

How is glaucoma treated?

  • Your doctor will prescribe you certain medication (Eye drops and tablets) so as to lower your eye pressure. You must use the medicines regularly as directed by your ophthalmologist.

  • You should not stop medicines even if you do not have symptoms.

  • A regular follow up, as advised by your doctor, is mandatory.

Laser treatment

If glaucoma is not controlled with the help of medicines, if the side effects of the medicines are not well tolerated and the patient is non-compliant, or cannot afford the cost of the medicines, the second option is LASER TREATMENT, which is given to open up the drainage area for the fluid.

Operative procedures

(Glaucoma Filtering Microsurgery or “By-pass” surgery of eye) The operation for glaucoma is the only option left for patients in whom the eye pressure is not controlled with medication or laser. It is also the treatment of choice in non-compliant patients, and in infants and children with glaucoma. Filtering microsurgery involves creating a drainage hole with the use of a small surgical tool, to bypass the blockage in the eye’s trabecular meshwork (the eye’s drainage system). This opening helps increase the flow of fluid out of the eye and thereby reduce the eye pressure.

Things to remember about Glaucoma:

  • Glaucoma, like diabetes, cannot be cured only controlled

  • Vision lost due to glaucoma cannot be recovered

  • Early detection and treatment of glaucoma will prevent further loss of sight and blindness

  • It is essential that people above the age of 40 and those with family history of glaucoma should

  • have their eye examined periodically to detect glaucoma early

  • Once diagnosed as having glaucoma, the patient should be committed to life-long treatment and periodic eye check-ups.

  • Drugs prescribed by the doctor should be regularly used at the specified time to ensure round the clock pressure control.
