Understanding Glaucoma: Causes, Symptoms, and Treatment
Glaucoma is one of the leading causes of vision loss around the world, often called the “silent thief of sight” because it can damage your eyes without any early symptoms. It’s a serious eye condition that affects the optic nerve, usually due to increased pressure inside the eye (intraocular pressure). If not treated in time, glaucoma can lead to permanent vision loss.
What Is Glaucoma?
Glaucoma is a group of eye diseases that cause damage to the optic nerve—the part of the eye responsible for sending visual information to the brain. This damage is often caused by fluid buildup in the front part of the eye, which increases pressure and affects vision over time.
Common Causes of Glaucoma
High eye pressure (intraocular pressure)
Family history of glaucoma
Age (more common after 40 years)
Diabetes or high blood pressure
Eye injuries or long-term steroid use
Symptoms to Watch For
In the early stages, glaucoma may not cause noticeable symptoms. As it progresses, you might experience:
Blurred or tunnel vision
Eye pain or pressure
Headaches
Seeing halos around lights
Redness in the eyes
Regular eye checkups are essential because early detection can prevent serious damage.
Types of Glaucoma
Open-Angle Glaucoma – The most common form; develops slowly and painlessly.
Angle-Closure Glaucoma – A sudden rise in eye pressure causing severe pain and vision loss; a medical emergency.
Normal-Tension Glaucoma – Occurs even when eye pressure is normal, often due to poor blood flow to the optic nerve.
Treatment Options
While glaucoma cannot be cured, it can be managed effectively. Treatment includes:
Prescription eye drops to reduce eye pressure
Oral medications
Laser therapy or surgery in advanced cases
Prevention Tips
Get regular eye exams, especially if you’re over 40
Maintain healthy blood pressure and sugar levels
Exercise regularly to improve blood circulation
Avoid smoking and limit caffeine intake
Conclusion
Glaucoma is a serious but manageable eye condition if diagnosed early. Protect your vision by scheduling routine eye checkups and following your doctor’s advice. Remember, early detection is the key to preventing permanent vision loss.
