Glaucoma is an eye disease resulting in damage to the optic nerve that eventually results in the loss of vision. Early detection of glaucoma is vital to stop the disease from progressing. If glaucoma is not caught early and treated it can cause blindness. The optic nerve is responsible for carrying images from the eye to the brain. In the early stages of glaucoma, there may be no symptoms. Currently there is no cure for glaucoma, however, medication or surgery can prevent further loss of vision.
Eyesight and Surgery Associates’ own Dr. Jusko was the first eye surgeon in Western Mass to perform a new glaucoma procedure called iStent in 2013. This procedure is done simultaneously with cataract surgery and helps lower the eye pressure, often reducing the need for eye drops.
The most common form of glaucoma is open angle. Open angle glaucoma develops slowly over time and it occurs when the eye’s drainage canals become clogged. The inner eye pressure rises because the correct amount of fluid cannot drain out of the eye. Damage to the optic nerve is painless and a large portion of your vision can be lost before you are aware of the problem. In many cases, open angle glaucoma is treated with glaucoma medication, laser, or iStent surgery. In more severe situations, additional major eye surgery is necessary.
Angle-closure glaucoma is a dangerous form of the disease which can cause pain and blindness quickly. Angle-closure glaucoma occurs when the iris move forward to block the drainage angle shaped by the cornea and the iris. A sudden spike in intraocular pressure results and produces symptoms such as eye pain, redness, and nausea. This is a medical emergency. If the eye pressure is not reduced it can cause permanent vision loss.
