Glaucoma Treatment

Am I at Risk?

You are considered to be in a higher-than-normal risk category if you have any of the following:

  • High IOP
  • Age >40 years
  • Family history of glaucoma
  • History of eye injury
  • History of steroid use, topically / systemically
  • Are near-sighted (myopia, need minus powered spectacles)

Best advised getting diagnosis and glaucoma treatment in Nandyal Eye care Centre Kalburgi.

Other risk factors, which can be detected only on examination, include:

  • High eye pressure
  • Thin corneas
  • Differences in the optic nerves of both eyes
  • If you have any of these risk factors, you need to consult you, an eye specialist. Best advised getting diagnosis and glaucoma treatment at Nandyal Eye care Centre. We can determine your risk level and need for future check-ups. Truly a life-changing experience after glaucoma treatment in Nandyal Eye care Centre. !

Glaucoma is the name given to a set of different eye disorders which cause progressively increasing damage to the optic nerve, leading to progressive irreversible loss of visual field. The optic nerve connects and transmits visual signals from the eye to the brain. In most types of glaucoma, the pressure within the eye is higher than normal, and this high pressure directly damages the nerve. Not every eye with high pressures develops glaucoma, however, it is a known risk factor and people with high pressures, therefore, need regular eye examinations to rule out glaucoma. There is no specific level of eye pressure that definitely causes glaucoma or eliminates the risk of glaucoma. In some cases, normal pressures can still lead to glaucoma. Advanced glaucoma can lead to blindness, hence its early diagnosis and glaucoma treatment is imperative.

WHAT IS EYE PRESSURE?

The cornea and the lens are special parts of the eyeball responsible for focusing and transmitting light. For this purpose, they require to be crystal clear. Blood vessels, which normally supply nutrition to cells, are absent from these parts of the eyeball, as they will reduce their clarity. In order to supply nutrition to these sensitive parts, a special liquid, called the aqueous humor is produced in the eye. This liquid bathes the lens and back surface of the cornea and then drains out of the eye through the ‘trabecular meshwork’, situated in the angle of the eye. When the normal outflow is blocked due to any cause, the pressure in the eye builds up, like a blocked sink. Eye pressures above the normal upper limit of 20 mmHg can lead to optic nerve damage – the mechanism for most types of glaucoma.

CAUSES OF GLAUCOMA

Glaucoma can occur without any other eye disease is present. This is called Primary glaucoma and can be of two types – Open-angle or Closed-angle depending on the status of the drainage angle.
Occasionally, glaucoma can be a complication of other eye diseases. This is then called Secondary glaucoma and can occur due to injury, eye inflammation, cataract, advanced diabetes, and the use of certain medicines.
Glaucoma can also occur as a congenital entity in newborns, due to abnormal development of the eyeball which does not allow the aqueous fluid to be drained out normally. Get more information from our eye specialists at Nandyal Eye care Centre Kalburgi.

HOW DO YOU KNOW IF YOU HAVE GLAUCOMA?

Glaucoma being a silent thief of sight, rarely has any symptoms. Very often, patients come to us with complete loss of vision in one eye. Sometimes, in cases of closed-angle glaucoma, patients complain of headaches which are more in the evenings or in the dark. They may also complain of seeing colored haloes (rainbows) of light when their eye pressure rises. In case of an attack of acute angle-closure, the patient may complain of severe headache, redness of the eyes, and sudden blurring of vision. This may be associated with nausea and vomiting and can mimic an abdominal emergency. In India, angle-closure accounts for nearly 40% of all cases of glaucoma, and these are the patients who progress to blindness very rapidly. Hence it is very important to diagnose these patients early and prevent the progression of the disease by treating it promptly.
Children with Congenital Glaucoma typically have large eyes, with photophobia and watering. If diagnosed and treated in time these are the eyes where early damage to the optic nerve may be reversed. Best advised getting diagnosis at Nandyal Eye care Centre Kalburgi.
