Glaucoma is an eye disease where increased intraocular eye pressure can slowly damage the optic nerve. The disease’s cause is typically that fluid is allowed to accumulate in the eye, and the pressure increases like too much water in a balloon. This occurs when fluids are not allowed to circulate properly.
This disease is particularly dangerous for several reasons. Glaucoma is asymptomatic during early stages. As eye pressure increases in the eye, optic nerve damage will lead to a very gradual loss of peripheral vision. This loss of vision will slowly make its way towards the central vision. This loss of vision is permanent! For this reason, many ophthalmologists refer to glaucoma as the “silent thief of sight”. When the optic nerve is damaged, it cannot be repaired, thus early detection and preventive measures are your best defense against this disease.
