Glaucoma
WHAT IS GLAUCOMA?
A glaucoma is a group of conditions in which high pressure inside the eye (intraocular pressure) damages the eye’s optic nerve. Glaucoma usually affects both eyes. It commonly occurs in adults above 40 years of age, but can even occur in newborn babies.
Vision loss due to glaucoma is irreversible; hence, it is very important to detect this disease as early as possible and treat it early to preserve vision.

HOW DO I KNOW IF I HAVE Glaucoma?
Symptoms of Glaucoma, if you have Glaucoma you may observe
Cloudy or blurry vision
A cataract is a clouding of the lens of the eye. It can be caused by age, injury, or disease.
Severe Eye or Forehead Pain
Pain around the eyes when coming out from darkness (e.g., as soon as the person comes out of a cinema hall)
Peripheral Vision Loss
The gradual decrease of side vision with the progression of glaucoma
Halos Around Lights
Coloured halo rings are seen around light bulbs, especially in the mornings and nights
Redness of the Eyes
Frequent change of reading glasses, headaches, pain and redness of the eyes
Frequently Asked Questions
Few commonly asked questions about Glaucoma, these question will help you to understand better about Glaucoma.
Who is at risk for glaucoma?
Anyone can develop glaucoma. Some people are at higher risk than others. They include:
- Everyone over the age of 40
- People with a family history of glaucoma.
- Diabetics.
- People with nearsightedness (Myopia) for open-angle type and farsightedness (hyperopia) for close angle type.
When should i get my eye tested for glaucoma?
- If you have a family history of glaucoma
- If you experience blurring of vision
- If you see haloes around light
- If you suffer from frequent headaches
how glaucoma diagnosed?
The Applanation tonometry test measures the inner pressure of the eye. Usually, drops are used to numb the eye. Then the doctor or technician will use a special device that measures the eye’s pressure.
Ophthalmoscopy is used to examine the inside of the eye, especially the optic nerve. In a darkened room, the doctor will magnify your eye by using an ophthalmoscope (an instrument with a small light on the end). This helps the doctor look at the shape and color of the optic nerve.
Perimetry is a procedure where the patient wears a patch over one eye and looks straight ahead at a bowl-shaped white area. At the same time, the computer presents lights in
fixed locations around the bowl. The patient indicates each time he or she sees a light, which is why perimetry is able to provide a map of the visual fields. The type of vision loss associated with glaucoma is relatively specific, and perimetry can detect the typical visual-field defects of glaucoma disorder. The perimetry test is also called a visual field test.
Retinal Nerve Fibre Analysis/OCT Nerve fibre analysis is a newer method of glaucoma testing in which the thickness of the nerve fibre layer is measured. Thinner areas may indicate damage caused by glaucoma. This test is especially good for patients who may be considered to be a glaucoma suspect and also to indicate if a person’s glaucoma is progressively becoming worse. The OCT instrument utilizes a technique called optical coherence tomography which creates images by use of special beams of light. The OCT machine can create a contour map of the optic nerve, and optic cup and measure the retinal nerve fiber thickness. Over time this machine can detect the loss of optic nerve fibers.
