Glaucoma is a group of diseases that cause damage to the optic nerve. It is one of the leading causes of blindness in people over 60.
There are many different types of glaucoma, but the 2 most common types are open-angle glaucoma and angle-closure glaucoma. Other types of glaucoma include:
- Normal-tension glaucoma
- Congenital glaucoma
- Secondary glaucoma
- Pigmentary glaucoma
- Pseudoexfoliative glaucoma
- Traumatic glaucoma
- Neovascular glaucoma
- Irido corneal endothelial syndrome (ICE)
- Uveitic glaucoma
Open-Angle Glaucoma
Open-angle glaucoma is the most common type of glaucoma. The disease has been dubbed “the silent thief of sight” because it has no symptoms until the damage is quite far along.
With open-angle glaucoma, fluid builds up in the eye, increasing pressure, even though the drainage angle remains open. Since there are so few noticeable symptoms, regular eye exams are critical in detecting glaucoma early.
Angle-closure Glaucoma
Unlike open-angle glaucoma, angle-closure glaucoma can come on fast, with painful symptoms. This type of glaucoma occurs when the drainage in the eye is blocked, and intraocular pressure increases quickly.
Warning signs of an angle-closure glaucoma attack include:
- Severe pain in the eye
- Sudden intense headaches
- Eye redness
- A sudden decrease in vision
- The appearance of halos or rainbows
- Nausea
- Vomiting
Angle-closure glaucoma is considered a medical emergency. Seek help immediately.
Our doctors at StylEyes test for glaucoma using a Goldmann applanation tonometer. This test determines intraocular pressure, which can give us clues to your eye health.
Any damage to the optic nerve that’s occurred due to glaucoma can’t be reversed, but there are treatments that can lower the pressure in the eye, such as:
- Eye drops
- Oral medication
- Surgery
