Glaucoma is a disease that damages your eye’s optic nerve. It usually happens when fluid Increase in pressure in Anterior Chamber. That extra fluid increases the pressure in your eye, damaging the optic nerve.

This year's theme is 'B-I-G' Beat Invisible Glaucoma'

To highlight The World Glaucoma Week, the Eye Doctors of Bangalore are emphasizing that early detection is essential to slow development of Glaucoma and those routine eye examinations are the only method to discover ‘symptomless Glaucoma’ early. In a late period, Glaucoma is irreversible and results in sight loss and blindness.

Based on our growing and ageing population, the level of the eye disease is expected to rise in Bangalore city over the coming decade, but treatment for Glaucoma works very well if discovered early and generally entails eye drops alone.

Early detection of Glaucoma is key to prevent after vision reduction, as is the importance of sight tests to detect possible Glaucoma so it can be diagnosed by My Vision Eye Clinic’s Dr.Rinku and handled in the area where possible.

Most common type of glaucoma

Primary open-angle glaucoma (POAG)

The buildup of fluid pressure in the eye happens quite slowly. The angle where our iris meets the cornea is open but also the both eye's drainage canals become clogged over time, causing an increase in eye pressure and following optic nerve damage.

Most people who've POAG feel beautiful and don't notice a change in their vision initially since the very initial loss of vision is of the either peripheral or side view, and the visual acuity or sharpness of eye vision is maintained till late in the disease.

From the time a patient is aware of vision loss, the disease is usually quite advanced. Vision loss from glaucoma isn't cured with treatment, even with surgery.

Because POAG has a couple of warning signs or symptoms before damage has occurred, it is vital to find a Best eye doctor in Bangalore for routine eye exams. If glaucoma is being detected, Dr.Rinku can prescribe a preventive treatment to help protect your vision.

What are the symptoms of angle-closure glaucoma?

Primary angle-closure is an illness in which the angle is shut in many or most areas; this may cause increased eye pressure which can result in optic nerve damage. Treatment in the early stages can help minimize the possibility of developing glaucoma. In most patients with the main angle-closure, there is a gradual rise in eye pressure, and there are no noticeable symptoms.

Less commonly, the eye pressure multiplies and is called an intense attack of angle-closure. This, the pressure level is excellent, and optic nerve damage may happen quickly. Some individuals with angle-closure might have transient episodes of high eye pressure that can be mistaken as migraine headaches.

Symptoms of severe angle-closure are very noticeable and can consist of hazy or blurry vision, critical eye and head pain, nausea or vomiting (uncontrollable severe eye pain), the visual appeal of rainbow-colored circles around bright lights, or abrupt sight loss. If you experience any of these above symptoms, please contact My Vision eye clinic immediately.

There are other several types of glaucoma in the world.

The two major types are:

1. Open-angle glaucoma
2. Angle-closure glaucoma

They are indicated by an increase of intraocular pressure (IOP) or pressure within the eye itself.

1. Open-Angle Glaucoma

Open-angle glaucoma is a very common form of glaucoma, accounting for at least 90% of glaucoma cases is caused by the slow functioning of the drainage canals, leading to increased eye pressure.

  • Has a full and open-angle between the iris and cornea
  • Develops slowly and is a lifelong illness
  • Has damage and symptoms that aren't noticed.

"Open-angle" like the angle where the iris meets the cornea is as wide and open as it needs to be. Open-angle glaucoma is also termed as primary or chronic glaucoma. It is a very common type of glaucoma, affecting about three million Indians.

2.Angle-Closure Glaucoma

Angle-closure glaucoma, an uncommon type of glaucoma:

  • Is happens by blocked drainage canals, resulting in a sudden rise in intraocular pressure
  • Includes a closed or narrow-angle within the iris and cornea develops very rapidly
  • Has its symptoms and damage that are usually very noticeable and
  • Demands immediate medical care

It is also termed acute glaucoma or narrow-angle glaucoma. Contrary to open-angle glaucoma, angle-closure glaucoma is a result of the angle between the iris and cornea closing. They are also called low-tension or normal-pressure glaucoma. Back in normal-tension glaucoma, the optic nerve is damaged though the eye pressure isn't very high.

Congenital (childhood) glaucoma:

This kind of glaucoma occurs in babies when there's an erroneous or incomplete development of the eye's drainage canals during the prenatal period.

Normal-tension glaucoma:

This is an uncommon condition which may be inherited. When pure, microsurgery can often fix structural flaws. Other instances are treated with medication and surgery.

Additional Types of Glaucoma:

  • Variants of open-angle and angle-closure glaucoma include:
  • Pseudo exfoliative Glaucoma
  • Traumatic Glaucoma
  • Neovascular Glaucoma
  • Iaido Corneal Endothelial Syndrome (ICE)
  • Uveitic Glaucoma

In My Vision Eye Clinic the glaucoma specialist will weigh all of these factors before deciding whether you need treatment for glaucoma, or whether you should be monitored closely as a glaucoma suspect. Being glaucoma suspect means your risk of developing glaucoma is higher than normal, and you need to have regular examination to detect the early signs of damage to the optic nerve.

A comprehensive eye examination is required to detect Glaucoma.

  • Visual Acuity
  • Applanation Tonometry (to measure IOP)
  • Gonioscopy – to diagnose it’s an Open angle and Closed Angle

There is no cure for glaucoma, but regular intervention can save your vision. Treatments of glaucoma can vary from simple medications to surgery. The ophthalmologist can select the best course of treatment based on the individual conditions in your case.
