Clear, healthy vision allows you to enjoy every moment of life - but some eye conditions can quietly threaten it over time. Glaucoma is one of the leading causes of vision loss worldwide, often progressing without noticeable symptoms in its early stages. Since damage from glaucoma cannot be reversed, early detection through routine eye exams is the most effective way to protect your sight and maintain lifelong eye health.
Glaucoma is a group of eye diseases that damage the optic nerve, the part of the eye responsible for transmitting visual information to your brain. This damage is often linked to increased pressure inside the eye (intraocular pressure), though not all cases are pressure-related. Over time, the damage caused by glaucoma can lead to peripheral vision loss and, if untreated, total blindness.
There are several forms of glaucoma, but the two most common are:
Open-Angle Glaucoma: The most prevalent type, where fluid drains too slowly, gradually increasing eye pressure over time.
Angle-Closure Glaucoma: A more sudden form that occurs when the drainage angle between the iris and cornea becomes blocked, causing a rapid rise in eye pressure that requires immediate medical attention.
Other types include normal-tension glaucoma (optic nerve damage despite normal pressure) and congenital glaucoma (present at birth).
Because glaucoma usually develops without pain or noticeable vision changes, regular eye exams are essential for early detection. During a glaucoma evaluation, your optometrist will:
Measure your intraocular pressure (IOP)
Examine your optic nerve for signs of damage
Perform visual field tests to check peripheral vision
Evaluate your corneal thickness and drainage angle
Early diagnosis allows for proactive management, helping to preserve your vision for years to come.
While glaucoma often progresses silently, you should schedule an eye exam promptly if you experience:
Blurred or patchy vision
Loss of peripheral vision
Eye pain or redness
Seeing halos around lights
Headaches or nausea
If diagnosed early, glaucoma can often be managed effectively to prevent further vision loss. Treatment focuses on lowering eye pressure and may include:
Prescription Eye Drops: The most common first line of defense to reduce fluid production or increase drainage.
Oral Medications: Used in certain cases to further control eye pressure.
Laser Therapy: Can help improve fluid drainage and reduce pressure.
Surgical Options: If pressure remains uncontrolled, surgery may be necessary. When this is the best course of action, our optometrist will refer you to a specialist.
Glaucoma is a serious condition, but with consistent monitoring and timely treatment, its progression can often be managed effectively. Regular eye exams give your doctor the best opportunity to identify glaucoma in its earliest stages and protect your vision for the future.
