1. What is glaucoma?
Glaucoma is a condition that damages the optic nerve in the eye. This nerve is essential for vision as it connects the eye to the brain.
2. What are the symptoms of glaucoma?
The symptoms of glaucoma vary with the stage. However, the following are some of the symptoms:
- Patchy blind spots in the eyes
- Pain in the eyes
- Blurring of vision
- Vomiting and nausea
- Redness of the eyes
- Watering of eyes
3. What causes glaucoma?
The increased pressure due to excess fluid in the eye causes glaucoma. This damages the optic nerve if left untreated. Normally, the fluid is drained from the eye continuously, maintaining the pressure in the eye. The excess production or improper drainage of this fluid causes glaucoma. Genetic factors and high blood pressure too can lead to glaucoma.
4. Who are at a high risk of glaucoma?
Following factors increase the risk of developing glaucoma:
- Age over 60 years
- Family history of glaucoma
- Abnormally thin centre of the cornea (a layer of the eyes)
- Extremely nearsighted or farsighted
- High internal pressure in the eyes
- Diseases like heart problems, diabetes, sickle cell anemia and high blood pressure
- Corticosteroid medications
- Eye injury or eye surgery
5. How will your doctor diagnose glaucoma?
The following tests are performed for the diagnosis of glaucoma:
- Visual acuity test to check how far you can see clearly
- Visual field test to check your side vision
- Dilated eye exam in which an eye drop is used to dilate (widen) your pupils and eyes are examined with a magnifying glass
- Tonometry to measure the pressure in the eyes
- Pachymetry to measure the thickness of the cornea
Glaucoma is an eye condition that causes an increase of pressure in the eye that leads to optic nerve damage. It can occur at any age but most commonly seen in older adults. Usually, glaucoma has no early warning signs, but the condition gradually worsens the vision that leads to irreversible permanent blindness. So it's necessary to have a frequent eye examination.
Aqueous humor which is the fluid inside the eye flows through a mesh-like channel. If these channels are blocked partially or completely, the natural pressure in the eye increases which leads to intraocular pressure (IOP). The increased IOP may cause damage to the optic nerve that leads to losing the vision or complete blindness.
Risk factors of glaucoma include:
Five different types of glaucoma are there:
The signs of glaucoma differ based on the stage and type of the condition.
Well experienced and qualified Ophthalmologists can treat glaucoma. Depending on the severity of the disease, doctors can prescribe medications and eye drops. Ophthalmologists can also perform glaucoma surgery.
The approximate price for glaucoma treatment can range from 10,000 to 50,000 in Hyderabad. The cost may vary depending on the following factors:
However, this is not an exact cost for glaucoma treatment in Hyderabad. So, please have a discussion with an Ophthalmologist regarding the cost.
Doctors will review medical history and perform a physical examination. After these, the following few tests may be suggested:
The damage or loss of vision due to glaucoma cannot be reversed. However, the treatment can further prevent vision loss when there is an early diagnosis. The treatment mainly focuses on decreasing intraocular pressure. Based on the condition, treatment may be eye drops, oral medications, and surgery, or a combination of any of these.
Some of the health care tips and measures that can help to control eye pressure are:
