Glaucoma refers to elements of eye issues that lead to harm to the optic nerve, which carries visual information from the eye to the brain. The disease is related to the increased intraocular pressure in which damage to the optic nerve can take away eye vision including blindness.
Causes of Glaucoma
The inside of the front of your eye is filled with a watery type’s fluid called the aqueous humor. This fluid in your eye creates intraocular pressure (IOP), which keeps it healthy and in the right shape. The aqueous humor is different from tears. In patients with glaucoma, the drainage system of the eye becomes blocked so the intraocular fluid cannot drain. The aqueous fluid builds up as a result of that causing to build pressure inside the eye. This high pressure harms eye nerve resulting in loss of vision and even blindness.
Types of Glaucoma
The main types of Glaucoma are given below:
- Primary open angle glaucoma – Primary open-angle glaucoma is the most common type of glaucoma. It develops when the drainage system of the eye becomes blocked over time. IOP increases because the fluid cannot drain out of the eye. The kind of glaucoma occurs slowly and people who suffer from primary open-angle glaucoma do not notice any signs for many years. A majority of Glaucoma patients experience no symptoms and no early warning signs. If the problem is not treated at the right time, it can cause vision loss. The good news is that the problem usually responds to medication if it is caught at an early stage. Careprost eye drop is very effective in treating patients with Glaucoma.
- Closed-angle glaucoma – It can also be called as acute glaucoma or narrow-angle It is very rare and different from open-angle glaucoma. In this type of glaucoma, damage to the eye nerve (optic nerve) happens very quickly due to a sudden increase in intraocular pressure.
- Normal tension glaucoma – Normal tension glaucoma develops when IOP of less than 21mmHg still causes damage to the eye nerve. The type of glaucoma can also be called as low-tension glaucoma. It is believed to be associated with the poor blood flow to the optic nerve, which causes cell death (death of cells that carry impulses from the retina to the brain). The kind of glaucoma can be diagnosed by repeated examinations by eye specialists to find out the optic nerve damage or the vision loss.
- Secondary glaucoma – Secondary eye glaucoma occurs as a result of other eye conditions such as an injury, tumor, and inflammation or in advanced cases of diabetes mellitus or cataract. The problem may also occur due to the use of certain medications such as steroids. The type of glaucoma may be mild or severe. The treatments depend on whether it is open or close angle glaucoma.
- Congenital glaucoma – Congenital glaucoma is when a baby is born with glaucoma. It is a rare inherited type of open-angle If your baby is diagnosed with congenital glaucoma, then this means your baby’s drainage area is not properly developed before birth. This causes elevated pressure in the eye that can lead to vision loss from optic nerve damage and also to an enlarged eye. Early treatment with careprost drugs or surgery is critical in young children to preserve their sight.
