What is Glaucoma? Understanding the Silent Thief of Sight

At Blue Fin Vision, our premier eye clinic on Harley Street in London, we often encounter patients seeking information about glaucoma. This complex eye condition, often referred to as the “silent thief of sight,” is a leading cause of irreversible blindness worldwide. In this comprehensive guide, we’ll explore what glaucoma is, its causes, symptoms, and the cutting-edge treatments available at our London clinic.

Understanding Glaucoma

Glaucoma is not a single disease but rather a group of eye conditions that damage the optic nerve, which is crucial for transferring visual information from the eye to the brain. This damage can result in sight loss and even blindness. There are three main types of glaucoma: primary, secondary, and developmental (glaucoma in babies and children).

Key Facts About Glaucoma

  • It’s the leading cause of irreversible blindness globally.
  • Over 700,000 people in the UK have glaucoma, with half unaware they have it.
  • Early detection and treatment are vital to prevent vision loss.
  • Regular eye check-ups are crucial, especially for those at higher risk.

Types of Glaucoma

At our Harley Street clinic, we diagnose and treat various types of glaucoma:

  1. Primary Glaucoma
    • Primary Open Angle Glaucoma (POAG): The most common form
    • Primary Angle Closure Glaucoma (PACG): Can be acute or chronic
  2. Secondary Glaucoma
    • Includes pigmentary, neovascular, uveitic glaucoma, and trauma-related cases
  3. Developmental Glaucoma
    • Affects babies and children

The Structure of the Eye and Glaucoma

Understanding the eye’s structure is crucial to comprehending glaucoma:

  • The eye is ball-shaped, with a tough white outer coat (sclera) covered by the conjunctiva.
  • The front of the eye has a clear coat called the cornea.
  • Behind the cornea is the iris (the coloured part) with the pupil at its centre.
  • The lens is suspended behind the pupil.
  • Aqueous humor, a clear fluid, fills the space between the cornea and lens, maintaining eye pressure (intraocular pressure or IOP).

Causes and Risk Factors of Glaucoma

While the exact cause of glaucoma isn’t always clear, several risk factors have been identified:

  • Age: Risk increases with age, especially after 40.
  • Family History: Glaucoma tends to run in families.
  • Ethnicity: People of African, Caribbean, or Asian origin are at higher risk.
  • Medical Conditions: Diabetes, high blood pressure, and heart disease can increase risk.
  • Eye Injuries or Surgery: Previous eye trauma can lead to secondary glaucoma.
  • Prolonged Use of Corticosteroids: Especially eye drops.

At Blue Fin Vision, we take a comprehensive approach to assess your individual risk factors during our thorough eye examinations.

Symptoms of Glaucoma

One of the challenges with glaucoma is that it often develops without noticeable symptoms, especially in its early stages. This is why it’s often called the “silent thief of sight.” However, depending on the type and stage of glaucoma, symptoms may include:

Open-Angle Glaucoma Symptoms

  • Gradual loss of peripheral vision, usually in both eyes
  • Tunnel vision in advanced stages

Acute Angle-Closure Glaucoma Symptoms

  • Sudden, severe eye pain
  • Headache
  • Nausea and vomiting
  • Blurred vision
  • Halos around lights
  • Eye redness

It’s crucial to understand that by the time noticeable symptoms occur, significant damage may have already been done. This underscores the importance of regular eye check-ups at a reputable eye clinic like Blue Fin Vision in London.

Diagnosing Glaucoma

At Blue Fin Vision, we use state-of-the-art technology to diagnose glaucoma early. Our comprehensive glaucoma screening includes:

  1. Tonometry: Measures intraocular pressure
  2. Ophthalmoscopy: Examines the optic nerve for damage
  3. Perimetry: Tests peripheral vision
  4. Gonioscopy: Inspects the drainage angle of the eye
  5. Pachymetry: Measures corneal thickness
  6. Optical Coherence Tomography (OCT): Provides detailed images of the optic nerve

Early detection through these advanced diagnostic techniques allows us to start treatment promptly, significantly improving outcomes for our patients.

Treatment Options for Glaucoma

While there’s no cure for glaucoma, treatment can help slow or prevent vision loss. At Blue Fin Vision, we offer a range of treatment options tailored to each patient’s specific needs:

  1. Eye Drops
  • Often the first line of treatment
  • Helps lower intraocular pressure
  • Various types available, including prostaglandins, beta-blockers, and carbonic anhydrase inhibitors
  1. Oral Medications
  • Used when eye drops alone aren’t effective
  • Can help further reduce eye pressure
  1. Laser Therapy
  • Selective Laser Trabeculoplasty (SLT): A first-line treatment that reduces aqueous production in the eye. This minimally invasive procedure is increasingly being performed trans-sclera by trained nurses.
  • Laser Trabeculoplasty: For open-angle glaucoma
  • Laser Iridotomy: For angle-closure glaucoma
  1. Surgery
  • Trabeculectomy: Creates a new drainage channel
  • Drainage Implant Surgery: Inserts a small tube to help drain fluid
  • Minimally Invasive Glaucoma Surgery (MIGS): Newer, less invasive options that can be performed during cataract surgery or as a separate procedure

Our experienced ophthalmologists at Blue Fin Vision will work with you to determine the most appropriate treatment plan based on the type and severity of your glaucoma, as well as your overall health and lifestyle factors.

Living with Glaucoma: Tips and Advice

Being diagnosed with glaucoma can be concerning, but with proper management, most people maintain good vision throughout their lives. Here are some tips for living with glaucoma:

  • Adhere to Your Treatment Plan: Take medications as prescribed and attend all follow-up appointments.
  • Regular Exercise: Moderate exercise can help lower intraocular pressure.
