Glaucoma is a disease of the eye that damages the optic nerve and can cause blindness. In fact it is the leading cause of blindness and can appear in children and young adults as well. Glaucoma may occur when the natural fluids of the eye are impeded from draining properly, causing intraocular pressure (IOP) to build which may damage the optic nerve. Routine eye examinations are the best way to detect glaucoma. There are several types of glaucoma, all of which cause damage to the optic nerve. |

| Signs and Symptoms of Glaucoma |
| |
|
Symptoms or signs of glaucoma are often absent in the earliest stages of the disease and unfortunately the impaired vision is sometimes the first sign of glaucoma. In other instances, symptoms and signs of glaucoma may include eye pain, clouded or haloed vision, red eyes, headaches, and nausea. So rush to the ophthalmologist when you recognize any such symptoms.

| Visual Field Test & Tonometry (NCT) |
| |
A visual field test is a method of measuring an individual's entire scope of vision, mapping the central and peripheral (side) vision. It is the most frequently used diagnostic to detect any signs of glaucoma & damage to the optic nerve. In addition, visual field tests are useful for detection of central or peripheral retinal disease, eyelid conditions optic nerve disease. The most advanced Oculus Twin field auto perimeter is used at the Paras vision centre for visual field test.
Another important investigation is tonometry which is performed to determine the intraocular pressure (IOP), the fluid pressure inside the eye. It is an important test in the evaluation of patients with glaucoma. The highly sophisticated Non Contact Tonometre is installed at the centre for measuring the intraocular pressure of the eye.

| Squint |
| |
Squint (strabismus) is the term used for the condition when the eyes are misaligned and not looking at the same thing. The most common form of it are when one eye either turns in or outwards. when one squeezes the eyelid partly closed to see more clearly or against bright sunlight is also one of the squints. When misalignment occurs each eye is directed at a different image and generally results in double vision (diplopia) which generally does not occur in childhood. Childhood squint often runs in families and can be corrected only after operation. |

| What are the Pre operative preparations? |
| |
| Individuals are advised to discontinue wearing contact lenses 1 day before surgery. Before the surgery, the patient's corneas are examined with a machine called pachymeter to determine their thickness and to measure their surface contour and a map is created. All precautions & examinations are done to make the surgery a success. In case the eye is found to be unfit for the procedure, surgery can be denied to the individual. |
| |
| What are the postoperative expectations? |
| |
The vision is expected to be blurry immediately after the surgery. You would start feeling the improvement the very next day and it would continue to improve over the next few weeks. You are instructed to use a course of antibiotic and anti-inflammatory eye drops and continued for few weeks following the surgery. Patients are also usually told to sleep much more and are given a darkened pair of shields to protect their eyes from bright lights and to prevent rubbing of the eyes when asleep and to reduce dry eyes. You should avoid contact of water during the first two weeks. |
| |
| Would you require glasses after the procedure? |
| |
| You might require the glasses if you are more than 40 years of age, else you would require presbyopia corrections.
