Understanding Glaucoma: Prevention, Treatment, and Management

Understanding Glaucoma: Prevention, Treatment, and Management

  • 01 Jan 2024

Welcome to “Vision Insights with Dr. Bhargav Kotadia,” your trusted source for eye health information. Today, we delve into glaucoma, often known as the “silent thief of sight.” This condition is one of the leading causes of irreversible blindness globally, and understanding it is essential for effective prevention and management.

What is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve, crucial for good vision. This damage is frequently linked to high eye pressure. The insidious nature of glaucoma means it often progresses unnoticed until significant vision loss occurs.

Causes and Risk Factors

  1. Elevated Intraocular Pressure (IOP): The primary risk factor.
  2. Age: Higher risk in individuals over 60.
  3. Ethnicity: Increased prevalence in African, Asian, and Hispanic populations.
  4. Family History: Genetic predisposition plays a role.
  5. Medical Conditions: Including diabetes, hypertension, and heart disease.

Types of Glaucoma

  1. Open-Angle Glaucoma: The most common, characterized by inefficient eye fluid drainage.
  2. Angle-Closure Glaucoma: Less common but a medical emergency, leading to rapid vision loss.

Symptoms to Be Aware Of

  •  ⁠Typically asymptomatic in early stages.
  • Loss of peripheral vision.
  •  ⁠In acute cases, symptoms like severe headache, eye pain, blurred vision, and halos around lights.

Accurate Diagnosis Techniques

Early and accurate diagnosis is key to managing glaucoma. Techniques include:

  1. Perimetry: This visual field test maps the complete field of vision to detect any early signs of blind spots caused by glaucoma.
  2. Optical Coherence Tomography (OCT): A non-invasive imaging test providing detailed images of the optic nerve and retina, helping assess the extent of damage caused by glaucoma.
  3. Gonioscopy: A diagnostic procedure to examine the drainage angle of the eye, assisting in identifying whether it’s open or closed-angle glaucoma.

Prevention Strategies

  • ⁠Regular eye exams, including IOP measurement, optic nerve assessment, and the above specialized tests.
  • ⁠Awareness and understanding of the condition.

Modern Treatment Options

  1. Medicated Eye Drops: Primary treatment to lower eye pressure.
  2. Oral Medications: Used alongside drops in some cases.
  3. Laser Therapy: To enhance drainage or reduce fluid production in the eye.
  4. Surgery: Considered for advanced glaucoma or when other treatments fail.

Living with Glaucoma

  • Strict adherence to treatment plans.
  • ⁠Regular monitoring through comprehensive eye exams.
  • Lifestyle modifications, including exercise and a balanced diet.
  • ⁠Avoiding activities that could elevate eye pressure.


While glaucoma is a significant eye health concern, early detection, accurate diagnosis, and consistent treatment can effectively manage it. Perimetry, OCT, and gonioscopy play critical roles in diagnosing and monitoring the disease.
