Early Signs of Glaucoma: What You Need to Know

Early Signs of Glaucoma: What You Need to Know

Glaucoma is a leading cause of irreversible vision loss and blindness, often called "the silent thief of sight" due to its subtle onset and slow progression. Understanding the early signs of glaucoma and knowing when to seek help can make a critical difference in preserving your vision.

What is Glaucoma?

Glaucoma is a group of eye conditions characterized by damage to the optic nerve, which is essential for vision. This damage is often, but not always, associated with an increase in intraocular pressure (IOP). If left untreated, glaucoma can lead to permanent vision loss, making early detection vital.

Why Early Detection Matters

Glaucoma can progress without noticeable symptoms in its early stages, which is why it’s crucial to understand the warning signs and have regular eye exams, especially if you’re at higher risk. Risk factors include age, family history, high intraocular pressure, and conditions like diabetes and hypertension.

Early Signs of Glaucoma

•       Loss of Peripheral Vision: In the early stages of open-angle glaucoma, the most common form, peripheral (side) vision gradually diminishes. You might not notice it immediately, as central vision remains intact, but it’s often detected during a routine eye exam.

•       Halos Around Lights: People with early-stage glaucoma sometimes report seeing halos or colored rings around lights, particularly at night. This symptom can also occur in other conditions but should prompt an eye examination if it persists.

•       Eye Redness and Pain: Angle-closure glaucoma can present suddenly with eye redness, intense pain, and blurred vision. This type is a medical emergency, and anyone experiencing these symptoms should seek immediate care.

•       Frequent Headaches: Headaches, particularly around the eyes, can be an indicator of increased intraocular pressure. While headaches alone aren’t a sign of glaucoma, they may appear with other symptoms, making an eye exam worthwhile.

•       Blurring Vision or Vision Fluctuations: Some forms of glaucoma cause gradual blurring of vision or vision that changes day-to-day. Blurred vision, especially if it worsens over time, can be a red flag.

When to See an Eye Doctor

Because glaucoma can progress without clear symptoms, regular eye exams are essential. Most eye doctors recommend a comprehensive eye exam annually, or more frequent if you’re over 60 or have risk factors. During these exams, your optometrist can perform tests to measure your eye pressure, assess the optic nerve, and monitor any changes over time.

While glaucoma cannot be cured, early diagnosis allows for effective management. Common treatments include:

•          Prescription Eye Drops: These reduce eye pressure, helping prevent further damage.

•          Laser Therapy: Laser treatments can improve fluid drainage in the eye, reducing pressure.

•          Surgery: In advanced cases, surgical options may be necessary to relieve pressure and preserve vision.
