Glaucoma is an eye disease that damages the optic nerve high pressure in the eye that leads to pain in eye, headache, low or blurred vision, red eyes, nausea and vomiting. Optic nerve plays a vital role in vision of our eyes because optic nerve sends visual information from the eye to the brain. If glaucoma is left untreated, you might get permanent blindness. Glaucoma is the second most reason of blindness. Glaucoma Treatment can be done by eye drops, laser treatment and surgery.
Types of glaucoma
• Open angle glaucoma: - This type of glaucoma happens when the resistance builds up in your eye’s drainage canal and it has no symptoms.
• Closed angle glaucoma: - This type of glaucoma is very rare and comes suddenly.
• Normal tension glaucoma: - In this type of glaucoma, the optic nerve damages even in very low pressure in eye.
• Congenital glaucoma: - Congenital glaucoma is found in newly born babies whose drainage canal of eye is not formed in the womb of the mother. Its symptoms are noticeable in childhood.
The causes of glaucoma
Our eye builds a kind of fluid called aqueous humor. This fluid drains out through drainage angle. This process maintains the ocular pressure. If the drainage angle doesn’t properly works, the fluid builds up and this lead to excess pressure in the eye and damages the optic nerve
