Protect Yourself Against Unnecessary Vision Loss From Glaucoma

At Coastside Eye Care, we hope you have perfect 20/20 vision your entire life. The best way to ensure that is to visit us for your annual eye exam so we can detect eye diseases before they impact your vision. This is particularly true of glaucoma.

Over 3 million American live with glaucoma, but only half of those are aware of it. Untreated glaucoma accounts for about 10% of cases of blindness in the states and is the second highest cause of blindness worldwide.

What is Glaucoma?

This quiet disease affects the optic nerve, spoiling the information highway between your eye and your brain. Without treatment, glaucoma can cause blindness in only a few years. There is no cure for glaucoma but the disease can be treated, controlled, or slowed with early diagnosis.

Glaucoma develops so slowly and painlessly that the vision changes are almost impossible to note. The early stages only affect your peripheral vision, making the onset barely perceptible even if you were trying to stay aware of it. Many sufferers do not notice the change until they are struggling with tunnel vision.

The only reliable way to avoid glaucoma is to have your eyes examined every year.

Types of Glaucoma

  • Open-angle: The most common type, accounting for 90% of all cases. Open-angle glaucoma develops extremely slowly, The eye’s fluid canals gradually become blocked and your intraocular pressure (IOP) builds, damaging the optic nerve.
  • Closed-angle: This variation happens very fast. There is not enough space between the cornea and iris for your fluid to drain properly, causing your IOP to rise drastically. This often presents with sudden symptoms such as headaches, nausea, vomiting, blurry or lost vision, and eye pain. Call us or visit a hospital if you experience this.
  • Normal tension: This type of glaucoma is troubling for doctors. The IOP is at normal levels but yet the optic nerve still becomes damaged.
  • Pediatric: Usually diagnosed by age 1 and present from birth, this is also known as congenital glaucoma. A birth defect in the eye’s drainage system causes pediatric glaucoma. This condition is extremely rare.

Are You at Risk of Developing Glaucoma?

Age is a major contributing factor to the development of glaucoma, along with nearsightedness. African-Americans are more likely to have this disease and to become visually impaired from glaucoma. Genetics play a big role in this condition, so if you have parents or siblings with glaucoma you could be more susceptible.

Diagnosing Glaucoma

During your regular eye exam, your optometrist will measure your eye pressure and the structure of your eye using advanced equipment. This way, they can detect any problems with your IOP and your optic nerve before glaucoma affects your vision. This can be done through tonometry, imaging technology, and optical coherence tomography.

  • Eye drops: These can help to reduce eye pressure or reduce how much fluid is produced in the eye. They usually do not come with side effects, although some report stinging or burning eyes and redness.
  • Oral Medication: These accomplish the same goals as eye drops: they control your eye pressure or they reduce the amount of fluid your eyes are producing. This type of medication is used to treat acute closed-angle glaucoma.
  • Microsurgery: There are a few surgical options for those with glaucoma. Laser surgery such as trabeculoplasty, iridotomy, or cyclophotocoagulation can be performed to either increase drainage or to reduce fluid production. Talk to your doctor if you would like to know more.
