Glaucoma affects many people, and it is one of the leading causes of blindness worldwide. Managing the condition requires understanding its causes, recognizing its symptoms, and knowing how other health conditions can influence its progression. Here is more information on glaucoma and its broader connection to your overall health:
What Is Glaucoma?
Glaucoma is a group of eye diseases that damage the optic nerve, which connects the eye to the brain. This damage is often linked to elevated intraocular pressure and can lead to permanent vision loss if left untreated. The condition typically progresses slowly, and some patients are unaware of it until significant damage has already occurred.
What Causes It?
The most common cause of glaucoma is increased intraocular pressure (IOP), the pressure inside the eye. When fluid in the eye, known as aqueous humor, does not drain properly, pressure builds and damages the optic nerve. In some cases, glaucoma can develop even with normal eye pressure, and this is why regular monitoring is valuable.
What Are the Symptoms?
Glaucoma may not present noticeable symptoms in its early stages, with vision remaining normal. As the condition progresses, a gradual loss of peripheral vision can occur. Other symptoms of open-angle glaucoma may include:
- Patchy blind spots in the side (peripheral) vision
- Central vision abnormalities
- Tunnel vision in the advanced stages
Acute angle-closure glaucoma is a less common form that constitutes a medical emergency. Its signs and symptoms appear suddenly and include severe headache, eye pain, nausea and vomiting, blurred vision, halos around lights, and eye redness. Immediate medical attention is required to prevent vision loss.
How Are Other Conditions Connected?
Several systemic health conditions are associated with glaucoma, and managing them plays a role in slowing its progression. Diabetes can damage blood vessels throughout the body, including those supplying the optic nerve, and people with diabetes face a higher risk of developing glaucoma. High blood pressure and cardiovascular disease may also affect ocular blood flow, increasing vulnerability to optic nerve damage. Working closely with your ophthalmologist and physician helps manage these intersecting factors effectively.
What Are the Treatment Options?
Treatment for glaucoma focuses on lowering intraocular pressure to prevent further optic nerve damage. When medication alone is insufficient, surgical or laser-based interventions may be recommended. Minimally invasive surgical options include the iStent® and the XEN® Gel Stent, and these help improve fluid drainage from the eye and offer a quick recovery time.
Selective laser trabeculoplasty (SLT) is a laser procedure that stimulates the eye’s drainage system to reduce pressure, and it can be repeated if necessary. For more advanced cases, laser cyclophotocoagulation and MicroPulse® Cyclo target the ciliary body, the part of the eye that produces fluid, to reduce overall pressure. Your ophthalmologist will recommend the most appropriate option based on your diagnosis, eye pressure levels, and overall health profile.

Glaucoma is a complex condition with connections that extend beyond the eyes, and understanding those links can make a difference in how the condition is managed. Treatment options, ranging from drops to advanced procedures like iStent®, XEN® Gel Stent, and MicroPulse® Cyclo, offer multiple options to protect your vision. Speak with your ophthalmologist to discuss a personalized treatment plan that accounts for your full health.
