Commonly known as the “silent thief of sight“, this is a severe eye ailment that can result in permanent vision loss if not addressed promptly. It is a significant global contributor to blindness, impacting numerous individuals. In the United States, over 3.4 million individuals aged 40 and above are estimated to have open-angle glaucoma, which is the predominant form of this condition.

What is Glaucoma? 

This is a group of eye conditions that damage the optic nerve, typically due to increased pressure within the eye. If left untreated, this elevated pressure can lead to significant harm to the optic nerve, disrupting the critical signals between the eye and the brain. As a result, individuals may experience blurred vision, tunnel vision, or even blindness. The World Health Organization estimates that over 80 million people worldwide are currently affected by glaucoma, and this number is expected to rise to over 111 million by 2040.

There are two primary types of glaucoma: open-angle, which is the most common and accounts for 70 to 90 percent of cases, and angle-closure, a less common form that can cause sudden and severe eye pain along with blurred vision. Understanding these conditions is vital for early detection and effective management.

Symptoms differ based on the type

• Open-angle glaucoma: This type often has no early symptoms, making regular eye exams essential for early detection. As the condition progresses, symptoms may includes; Gradual loss of peripheral vision, often in both eyes. 
• Angle-closure glaucoma: This is a medical emergency and must be treated immediately or blindness could result in one or two days. The symptoms includes; severe eye pain, nausea, vomiting, sudden visual disturbance, blurred vision, halos around lights, and redness of the eye.
  

Detecting Glaucoma 

While anyone can develop glaucoma, certain factors can increase your risk, making regular eye exams crucial if you fall into specific categories. Individuals over 60, particularly those of Hispanic or Latino descent, are at a higher risk, as are African Americans over the age of 40. Additionally, having a family history of glaucoma further elevates your risk. It’s important to discuss these risk factors with your doctor to determine the appropriate frequency of eye exams. Early detection and treatment are essential for preventing vision loss, so staying proactive about your eye health is key.

Glaucoma often presents no early symptoms, which makes regular eye exams essential for early detection and management. During these exams, your eye doctor will assess the health of your optic nerve and your overall vision. They may utilize a variety of tests, including a dilated eye exam to closely examine the optic nerve, gonioscopy to evaluate the angle between the iris and cornea, and Optical Coherence Tomography (OCT) to detect any changes in the optic nerve.

Additionally, tonometry is performed to measure eye pressure, while pachymetry assesses corneal thickness. A slit-lamp exam allows for a thorough examination of the eye’s interior, and visual acuity tests check for any vision loss. Finally, a visual field test evaluates your peripheral vision, helping to ensure comprehensive eye health.

Treatment Options 

Early intervention is essential to prevent further vision loss from glaucoma. While there is no cure for the condition, several effective treatment options are available to manage it. Medicated eye drops are commonly used to lower eye pressure, and laser treatment can enhance fluid drainage within the eye. In more advanced cases, surgical options may be necessary to alleviate pressure buildup. The best treatment approach will vary based on the type and severity of glaucoma, so it is crucial to consult your eye care professional for tailored recommendations and ongoing management.
