Glaucoma is a group of eye diseases that cause progressive
damage to the optic nerve. If left untreated, it can lead to blindness.
Glaucoma is often caused by an abnormally high pressure in
the eye. It is the second leading cause of blindness in the world, and the
third in India.
Who gets glaucoma?
Although glaucoma can affect any age group, including
babies, it is more common in older adults. Glaucoma has been called the 'silent
thief of sight "because most people with glaucoma has no early symptoms or
pain until it becomes severe.
There are many types of glaucoma, however, disorders can be
divided into two main categories: "open-angle" and "closed
angle" or "closed angle".
Symptoms of glaucoma
Symptoms may include:
Open-angle glaucoma - which is painless and does not have
acute attacks until the disease is at an advanced stage, the blind spots in
patches on your side (peripheral) or central vision on both sides.
Acute closed-angle - eye pain, headache, nausea and
vomiting, blurred vision, narrowing of vision, halos around lights.
Prevention
There is no cure for glaucoma, but vision loss due to the
condition can not be restored. The best way to prevent disease is to have
regular eye exams. And if they are over 40 or have a family history of
glaucoma, get your eye exam for this condition at least once a year.
Because early diagnosis can help control the disease and the
key to preserving vision.
World Glaucoma Week is observed worldwide from March 6 to
12. This is a joint initiative between the World Glaucoma Association and the
World Glaucoma Patient Association. The goal is to raise awareness about
glaucoma, while encouraging people to have regular eye tests, including checks
of the optic nerve.
