A less common form of Glaucoma is Closed Angle (or Narrow-Angle Glaucoma or Angle-Closure Glaucoma). Closed-Angle Glaucoma occurs when the drainage angle of the eye becomes blocked. Unlike Open-Angle Glaucoma, eye pressure usually goes up very fast. The pressure rises because the iris — the colored part of the eye — partially or completely blocks off the drainage angle. People of Asian descent and those with Hyperopia (farsightedness) tend to be more at risk for developing this form of Glaucoma.

If the drainage angle becomes completely blocked, eye pressure rises quickly resulting in a Closed-Angle Glaucoma attack. Symptoms of an attack include: severe eye or brow pain, redness of the eye, decreased or blurred vision, seeing colored rainbows or halos, headache, nausea, or vomiting.
A Closed-Angle Glaucoma attack is a medical emergency  and must be treated immediately.  Unfortunately, people at risk for developing Closed-Angle Glaucoma often have few or no symptoms before the attack.
People at risk for Closed-Angle Glaucoma should avoid over-the-counter decongestants and other medications where the packaging states not to use these products if you have Glaucoma.


"After developing cataracts on the left eye, I decided to have the cataracts removed.  I was hesitant to allow anyone to work on my eye.  Immediately after the surgery, my vision was somewhat blurry, but cleared within a few days.  The entire experience was not nearly as uncomfortable or frightening as I imagined, and my vision is greatly improved.  The credit I give to Dr. Boland, his expertise and his exceptional patient care, and also to his efficient and friendly staff."

-M. Jones

"When Dr. Boland suggested Lipiflow for my dry eyes after years of over the counter drops as well as prescription drops, hot compresses, changing makeup and creams, and eventually just going without and still not getting relief – I didn't hesitate to leap at the chance for this procedure. I didn't care about the cost. I wanted my life back and hoped that this might enable the outcome. Let me state without reserve that I couldn't be happier and so grateful that Dr. Boland has invested in this technology!"
