Glaucoma Therapy & Surgery
Although it’s often associated with older patients, glaucoma affects more than 3 million Americans of all ages, ethnic background, and lifestyles. People from Colorado, Utah, New Mexico, and Arizona come to us for glaucoma diagnosis and treatment from our fellowship-trained glaucoma specialist, Dr. Joshua Zastrocky, at Four Corners Eye Clinic.
What Is Glaucoma?
“Glaucoma” is a general term that is used to refer to a group of eye diseases in which the eye’s optic nerve is damaged. This results in a characteristic pattern of vision loss. Elevated pressure in the eye is a primary risk factor for glaucoma, but up to one-third pf people with glaucoma have no history of elevated eye pressure. The anterior chamber of the eye is filled with fluid that continually flows in and out through the open angle where the cornea and iris meet. Normally, your eyes self-regulate the amount of pressure inside through this drainage.
Glaucoma results when the eye is susceptible to optic nerve damage, for various reasons, at the given level of pressure. Over time, this can cause serious damage to the optic nerve, eventually leading to permanent loss of vision and even blindness.
Types of Glaucoma
Glaucoma typically presents as one of the following 2 types:
Open-angle glaucoma: This form of glaucoma is the more common one and typically comes on quite gradually. Over time, the affected eye gradually loses vision due to ongoing optic nerve damage. There are usually no symptoms until the disease is quite advanced.
Angle-closure glaucoma: This is a less common form of glaucoma and can be chronic or acute. Chronic angle closure glaucoma behaves very much like primary open angle glaucoma with gradual optic nerve damage occurring without symptoms. Acute angle closure glaucoma results from a sudden blockage of the eye’s drainage system, leading to very high eye pressure. This can result in very rapid loss of vision as well as pain, nausea, and vomiting. This form of glaucoma requires immediate medical attention.
A minority of patients experience low tension glaucoma, which is damage to the optic nerve even without increased eye pressure. In such cases, the optic nerve is less tolerant to pressure than normal. Another rare form of glaucoma is congenital glaucoma, in which children are born with a defect in the angle of the eye which impairs drainage.
Symptoms & Risk Factors
Initially, the more common forms of glaucoma may not cause any symptoms at all. This is partially why it’s important to have regular eye exams even if you’re not experiencing any symptoms. By detecting glaucoma before it causes visual disturbances, we can treat it and prevent vision loss.
The earliest and most common symptom of glaucoma is a change in your peripheral vision.
Although glaucoma can affect anyone, certain factors, some controllable and some not, can increase your risk. These include the following:
- Having diabetes
- Being over the age of 60
- Being of African or Hispanic descent
- A history of ocular trauma
- Corticosteroid use
- Having a family history of glaucoma

Although there is no cure for glaucoma, the physicians of Four Corners Eye Clinic offer several options for treating it effectively and preserving your vision. Your physician works closely with you to develop a treatment plan that reflects your lifestyle and the exact nature of your condition. Your options may include any of the following:
- Medicated eye drops: Prescription eye drops can help to regulate the amount of fluid in your eye to maintain a healthy eye pressure.
- Laser procedures: Depending on the severity of your condition, your physician may recommend laser surgery to help open the drainage passageway of your eyes.
- Minimally invasive glaucoma surgery (MIGS): This group of procedures is less invasive than traditional glaucoma surgery and may be a good option for certain patients. MIGS procedures are generally less effective in terms of pressure lowering than conventional glaucoma surgery.
- Conventional glaucoma surgery: This would include trabeculectomy as well as implantation of a tube shunt. Although this is the most invasive option, it’s also the most effective in terms if its ability to lower pressure. Permanent shunts in the eyes can keep the drainage systems functioning properly.
