Glaucoma is a group of eye disorders characterized by a progressive deterioration of the optic nerve. This damage to the optic nerve leads to blurred vision and vision loss. Glaucoma is characterized by increased intraocular pressure in the eye due to clogging the drainage angle. If not treated on time, glaucoma can cause irreversible damage to the optical nerve, impairing your vision permanently.
Eye surgeons around the world are still probing into the exact cause of glaucoma disease. However, a majority of cases are categorized as primary or secondary glaucoma. A patient can be said to be suffering from primary glaucoma if their condition cannot be linked to any specific known cause. On the other hand, secondary glaucoma has a direct cause, including the following:
• Advanced cataract
There are two main types of glaucoma disorders which are:
1. Open-Angle Glaucoma: In this open-angle glaucoma, the fluid passes slowly through the drainage angle, which mounts over time, narrowing the drainage angle due to fluid clogging. However, it's a painless condition.
2. Closed Angle Glaucoma: This is a chronic disorder where the iris bows inward. It causes pain and blurred vision.
3. Angle-Closure Glaucoma: This glaucoma disorder is caused due to physical contact between iris and cornea.
4. Traumatic Glaucoma: As its name indicates it develops when someone has any direct injury to the eyes. It can occur just after the injury or some years later.
Glaucoma symptoms differ from one patient to other, depending upon the magnitude of Glaucoma spread in the eye. The symptoms of open angle and closed angle glaucoma are totally different. Signs and symptoms of patients suffering closed-angle glaucoma disease are:
• Blurred Vision
• Severe pain in the glaucoma eye
• Nausea and vomiting
• Redness in the glaucoma eye
• The halo-like glow around the affected eye
• Vision problem in dim light
Glaucoma treatment depends highly depends on the severity of the glaucoma disorder. The treatment of Glaucoma in adults can be done through the following techniques.
• Laser Treatment for Glaucoma: There are a few options for laser treatment for Glaucoma.
Selective Laser Trabeculoplasty uses a laser to cut selective holes within the eye to remove clogs.
The Iridotomy technique uses a laser to create a hole near the iris, resulting in an increased flow of fluid.
• Endoscopic Cyclo Photocoagulation surgery (or ECP) is a form of glaucoma eye surgery that reduces the amount of fluid produced.
• Conventional Surgery: This type of glaucoma eye surgery is also known as filtration surgery, involves the creation of a new drainage channel which helps the fluid exit the eye.
