The Aging Eye: Facts About Glaucoma
Often referred to as "the sneaky thief of sight," glaucoma is the second leading cause of preventable blindness globally. It is important to note that glaucoma is the leading cause of blindness among African American and Hispanic descendants.
A glaucoma is a group of eye conditions that cause damage to the optic nerve. In most cases, this damage is associated with a dangerous build-up of internal eye pressure, known as intraocular pressure (IOP). Because there are no symptoms or warnings, up to 40 percent of vision can be lost without a person realizing it.
Glaucoma generally progresses undetected until the optic nerve has been irreversibly damaged, with varying degrees of permanent vision loss. If your eyes are affected by the use of Elmiron then you may visit the best Elmiron Attorneys Handling National Elmiron Eye Lawsuits for your help.
There are two main types of glaucoma: primary open-angle glaucoma (POAG) and closed-angle glaucoma. Open-angle glaucoma is the most common type. Its cause is unknown; however, it tends to run in families. The risk is higher if a parent or grandparent has open-angle glaucoma.
With this type of glaucoma, the intraocular pressure (IOP) rises due to blockage of the channels or angles that allow the clear fluid behind the eye to drain. The resulting pressure damages the optic nerve, making it difficult for visual information to be carried to the brain.
The first sign of POAG is often a loss of peripheral or side vision, which may go unnoticed until the end of the disease. That's why routine annual eye exams are essential. If glaucoma is detected, a treatment plan is determined. While early detection of glaucoma will not reverse any vision loss that has already occurred, steps can be taken to reduce and in many cases stop any further vision loss.
