What is Glaucoma?

Glaucoma can cause damage to your optic nerve. Your brain receives visual information from the optic nerve located between your eyes.

Glaucoma is often caused by excessive pressure in your eye. The increased pressure can cause damage to your optic nerve tissue and may eventually lead to blindness or vision loss. However, you may be able to prevent further vision loss if it is caught early.

What are the Signs of Glaucoma 

Primary open-angle glaucoma, the most common form of glaucoma, is the most prevalent. There are no symptoms, but gradual vision loss is the only sign. Therefore, it is important to have your eyes checked annually by an eye specialist or ophthalmologist. This will allow them to monitor any vision changes.

Acute-angle closure, also known as narrow-angle glaucoma or narrow-angle glaucoma, is a medical emergency.

? Severe eye pain

? Nausea

? Vomiting

? Redness in the eye

? Sudden vision disturbances

? See coloured rings around lights.

? Sudden blurred vision

What Causes Glaucoma in the Eye?

Aqueous humour is a clear fluid that your back produces continuously. This fluid fills your frontal part of the eye as it is being made. It then leaves your eye via channels in your cornea or iris. These channels may become partially or completely blocked, and the natural pressure of your eye (called the intraocular pressure, IOP) could increase. Your optic nerve can become damaged if your IOP rises. You may lose your sight as a result of nerve damage.

It is not always clear what causes pressure to rise in the eye. Doctors believe that one or more of the following factors could be responsible:

? Dilating eye drops

? Eyes that have blocked drainage

? Corticosteroids are medications

? Low or no blood flow to the optic nerve.

? High or elevated blood pressure

What Types of Glaucoma Are There?

There are five main types of glaucoma. These are:

Open-Angle (Chronic) Glaucoma

There are no open-angle or chronic Glaucoma symptoms other than gradual vision loss. However, your vision may suffer irreparable damage if this loss is not detected quickly. According to the National Eye Institute(NEI)Trusted Source, This is the most common type of glaucoma.

Angle-Closure (Acute) Glaucoma

The rapid buildup of fluid in your aqueous humour fluid can cause an abrupt increase in pressure. Therefore, angle-closure glaucoma should be considered an emergency. If you experience severe pain, nausea or blurred vision, it is important to contact your doctor immediately.

Congenital Glaucoma

Congenital glaucoma is a condition in which the angle of the eye can be affected. This causes fluid drainage to slow down or stop. Congenital glaucoma is characterized by excessive tearing, cloudy eyes and sensitivity to light. Congenital glaucoma is a common condition.

Secondary Glaucoma

Secondary glaucoma can be caused by injury, eye conditions such as cataracts and eye tumours. Secondary glaucoma can also be caused by medicines such as corticosteroids. Secondary glaucoma can be caused by eye surgery, but it is rare.

Normal-Tension Glaucoma

Some people can damage their optic nerves even if they don't have increased eye pressure. This is not known. This type of glaucoma could be caused by extreme sensitivity or decreased blood flow to the optic nerve.

How Is Glaucoma Treated?

Glaucoma treatment aims to lower IOP and stop further eyesight loss. Your doctor usually prescribes prescription eye drops. However, your doctor might recommend one of these treatments if the above doesn't work.

Medications

Many medications can be used to lower the IOP. These medications are available as eye drops or pills. However, drops are the most common. One or more of these medicines may be prescribed by your doctor.

Surgery

Your doctor might recommend surgery to drain fluid from a blocked channel or remove tissues responsible for increased IOP.

Angle-closure glaucoma treatment is different. Angle-closure glaucoma can be a serious medical emergency that requires immediate treatment to lower eye pressure. Although medicine is usually first tried to reverse the angle-closure, it may prove ineffective, and this can be done. Laser peripheral iridotomy, a laser procedure, may also be used. This procedure makes small holes in the iris to permit fluid movement.

Can a person with glaucoma go blind?

Vision loss can be stopped or slowed if the increased IOP is stopped and the pressure restored to normal. Unfortunately, glaucoma is a condition that can't be reversed. You will likely need to get a glaucoma specialist near you to control your IOP throughout your life. Glaucoma can't be reversed.

Can glaucoma be prevented?

Glaucoma cannot be prevented, but it is important to recognize it early to begin treatment. An annual preventive eye exam is the best way to detect any Glaucoma. Book an appointment on Sarwarpro with your Glaucoma specialist in Delhi. These routine eye exams may detect damage from glaucoma early enough to prevent it from progressing and causing vision loss.
