Glaucomas are a group of eye disorders characterized by progressive optic nerve damage. It is a condition in which there is a relative increase in intraocular pressure (pressure inside the eyes) which can lead to irreversible loss of vision.
Glaucoma is the second most common cause of loss of vision worldwide after cataract with more than 70 million people affected worldwide.
Glaucoma can occur at any age but is more common among people above 60 years of age. Several risk factors can increase the risk of glaucoma which include old age, family history of glaucoma, and history of eye injury. Other causes are poor blood flow to the optic nerve and conditions such as high blood pressure and diabetes.
Glaucoma is a silent thief of vision. In the early stages of glaucoma, there are no symptoms. In reality, most of those who have glaucoma are completely unaware of their condition. Hence regular eye checkups by an ophthalmologist play an important role in managing the disease at an early stage. Treatment protocols include medications and surgical procedures.
