What is Glaucoma: Types & Causes Explained?

Glaucoma is not just one eye disease, but a group of eye conditions that damage the optic nerve, often due to high pressure inside the eye (intraocular pressure, or IOP). The optic nerve is vital for good vision—it carries information from your eyes to your brain.

Main Types of Glaucoma

• Primary Open-Angle Glaucoma (POAG):
  By far the most common type. Drainage canals in the eye become less efficient over time, leading to slow pressure buildup. Symptoms develop gradually—most people don’t notice until vision loss occurs.
• Angle-Closure Glaucoma (also called Closed-Angle or Narrow-Angle):
  The eye's drainage angle suddenly becomes blocked, causing a rapid pressure rise. This is a medical emergency and can quickly lead to permanent vision loss.
• Normal-Tension Glaucoma:
  Optic nerve damage occurs even with normal eye pressure. Other factors (such as reduced blood flow) are believed to play a role.
• Secondary Glaucoma:
  Results from another eye condition, injury, inflammation, steroid use, or other diseases.
• Congenital or Childhood Glaucoma:
  Rare, may be present at birth due to abnormal eye development.

What Causes Glaucoma?

• Increased intraocular pressure (the most common culprit)
• Blocked or poorly functioning drainage canals in the eye
• Genetic predisposition/family history
• Past eye injuries or surgery
• Chronic eye inflammation
• Use of corticosteroid medications
• Other underlying medical conditions (diabetes, hypertension)

Remember: Not everyone with high eye pressure develops glaucoma, but it does increase your risk.

Why Glaucoma Matters for Your Health & Wellbeing

• Leading Cause of Preventable Blindness: Glaucoma is a top cause of blindness worldwide, but early detection and management can save vision (NEI).
• Often Symptomless: Most glaucoma progresses painlessly and unnoticed—until significant, irreversible vision loss occurs.
• Impact on Daily Living: Untreated glaucoma can affect reading, driving, recognizing faces, and independence.
• Quality of Life: Preserving eye health supports your confidence, safety, and enjoyment of life.

Common Challenges & Myths About Glaucoma

• Myth: Only elderly people get glaucoma.
  Truth: While risk increases with age, it can affect anyone—even babies and young adults.
• Myth: Glaucoma always has symptoms.
  Truth: It's often called the "silent thief of sight" because there are usually no early warning signs.
• Myth: Normal vision means healthy eyes.
  Truth: Peripheral vision may be slowly fading without your awareness.
• Challenge: Taking daily medications consistently can be hard, especially if you don’t feel different.
• Challenge: Accessing affordable, regular eye exams and specialist care.

Step-by-Step Solutions: How To Take Control of Glaucoma

1. Schedule Comprehensive Eye Exams:
   • If you’re over 40, get a baseline eye exam.
   • High-risk groups (family history, African or Hispanic/Latino descent, diabetes) may need earlier or more frequent checks.
2. Know the Warning Signs:
   • Sudden blurry vision, severe eye pain, halos around lights, nausea, and vomiting (seek emergency help—may be angle-closure glaucoma).
3. Follow Your Treatment Plan:
   • Use prescribed eye drops/medications every day.
   • Keep regular follow-up appointments, even if your vision seems fine.
4. Protect Your Eyes:
   • Wear safety glasses during sports or yard work.
   • Manage underlying conditions (blood pressure, diabetes).
5. Adopt Eye-Healthy Habits:
   • Stay active—regular, moderate exercise can reduce eye pressure (AAO).
   • Eat a balanced, nutrient-rich diet (plenty of leafy greens and omega-3s).
   • Don’t smoke—smoking increases optic nerve risk.

FAQs About Glaucoma: Types & Causes Explained

Real-Life Example: Maria’s Story

Maria, age 52, noticed no vision changes. During a routine optometrist visit, her eye pressure was found to be high. Thanks to early detection, she started daily drops and adjusted her diet. Five years on, Maria enjoys her hobbies and drives safely—proof that awareness and regular checks make all the difference!

Mistakes to Avoid With Glaucoma Management

• Skipping eye drops because you “feel fine.”
• Neglecting routine eye exams—catching changes early is crucial.
• Ignoring sudden vision changes or eye pain (seek emergency care if this happens).
• Assuming only seniors are at risk—know your family history and risk factors.
• Stopping medication or follow-up after symptoms appear to improve.
