Guarding Your Vision: Navigating the Path of Glaucoma Treatment and Prevention

Contents hide

Glaucoma, a condition frequently linked to increased eye pressure, is a significant contributor to irreversible vision loss and blindness worldwide. This blog post endeavours to offer a comprehensive insight into glaucoma treatment, with special emphasis on diverse approaches like minimally invasive glaucoma surgery, laser treatment, and prescription eye drops. Our aim is to enhance the clarity of information, refine the structure, and ensure the piece is easily digestible while preserving the original intent.

Understanding Glaucoma

Glaucoma is primarily related to the damage of the optic nerve, which is crucial for vision. This damage is often linked to high intraocular pressure (IOP). The disease is generally categorised into several types, such as open-angle glaucoma, angle closure glaucoma (including acute angle closure and chronic angle closure glaucoma), normal tension glaucoma, and congenital glaucoma.

Types of Glaucoma

Glaucoma is generally classified into several types, each with distinct characteristics and treatment approaches.

Primary Open Angle Glaucoma (POAG)Glaucoma Treatment symptoms melbourne

  • Prevalence: Most common form of glaucoma.
  • Symptoms: Often asymptomatic in early stages. However, peripheral vision progressively diminishes, typically affecting both eyes, and individuals may eventually experience tunnel vision in advanced stages.
  • Treatment: Typically includes eye drops, laser treatment, and possibly surgery.

Angle Closure Glaucoma

  • Subtypes: Acute Angle Closure Glaucoma and Chronic Angle Closure Glaucoma.
  • Symptoms:

Acute: Sudden onset of severe eye pain, blurred vision, headache, rainbow-coloured halos around lights, nausea, and vomiting.

Chronic: Can be asymptomatic or have symptoms similar to POAG.

  • Treatment: Emergency medical attention for acute cases; laser iridotomy and other surgical options for chronic cases.

Normal-Tension Glaucoma

  • Characteristics: Optic nerve damage occurs despite normal eye pressure.
  • Symptoms: Similar to POAG but occurs at lower eye pressures.
  • Treatment: Focuses on further lowering eye pressure.

Congenital Glaucoma

  • Onset: Present at birth or develops during infancy.
  • Symptoms: Excessive tearing, sensitivity to light, and enlarged eyes.
  • Treatment: Usually requires surgical intervention.

Secondary Glaucoma

  • Causes: Result of other medical conditions, such as uveitis, diabetes, or eye injuries.
  • Symptoms: Varies depending on the underlying cause.
  • Treatment: Aimed at the underlying cause as well as lowering eye pressure.

Risk Factors for Glaucoma

Understanding the risk factors is key in identifying individuals who are more prone to developing glaucoma.


  • Older individuals, typically over 60, are at higher risk, especially for open-angle glaucoma.


  • African, Asian, and Hispanic descent are associated with higher risks for certain types of glaucoma.

Family History

  • Having a family history of glaucoma increases the likelihood of developing the condition.

Medical Conditions

  • Diabetes, high blood pressure, heart disease, and other conditions can increase glaucoma risk.

Physical Injuries to the Eye

Other Eye-Related Factors

  • High myopia (nearsightedness), thin corneas, and chronic eye inflammation can elevate the risk.

Prolonged Corticosteroid Use

  • The use of corticosteroid medications, especially eye drops, can increase eye pressure.

Lifestyle Factors

  • Smoking and extreme obesity may also influence glaucoma risk.

Recognising the Symptoms of Glaucoma

Early detection of glaucoma is often challenging due to the lack of obvious symptoms in the initial stages, especially in the case of POAG and chronic angle closure glaucoma. The symptoms, when they do appear, can include:
  • Gradual loss of peripheral vision is a common occurrence in both eyes, characterised by a reduction in the visual field.
  • Tunnel vision in the advanced stages.
  • Acute angle closure glaucoma manifests through intense eye pain, accompanied by symptoms such as nausea, eye redness, and blurred vision.
  • In congenital glaucoma, symptoms like cloudiness of the eye, excessive tearing, and photophobia.

Glaucoma Diagnosis

The process of diagnosing glaucoma involves several tests and examinations, each playing a critical role in identifying the presence and type of glaucoma.

Comprehensive Eye Examination


  • Purpose: Measures intraocular pressure (IOP).
  • Procedure: A device applies a small amount of pressure to the eye, either with a tiny device making contact with the cornea or a puff of air.
  • Normal Range: Typically between 12-22 mm Hg. Higher values may indicate glaucoma.

Ophthalmoscopy (Dilated Eye Exam)

  • Purpose: Examines the shape and colour of the optic nerve.
  • Procedure: Eye drops are used to dilate the pupil, allowing the doctor to see through the eye to examine the optic nerve for signs of damage.
  • Indication: A cupped or hollowed appearance of the optic disc can indicate glaucoma.

Visual Field Test (Perimetry)

  • Purpose: Checks for areas of vision loss.
  • Procedure: The patient looks straight ahead and indicates when a moving light passes their peripheral vision. This test helps to map the visual field, identifying any areas of vision loss or blind spots.


  • Purpose: Measures corneal thickness.
  • Procedure: A specialised instrument, known as a pachymeter, is delicately applied to the cornea to precisely measure its thickness.
  • Significance: Corneal thickness can influence eye pressure readings; thinner corneas can be a risk factor for glaucoma.


  • Purpose: Examine the angle in the eye where the iris meets the cornea.
  • Procedure: A special contact lens with a mirror is used to see the angle clearly. This helps determine whether it is open or closed.
  • Relevance: Essential for diagnosing between open-angle and angle-closure glaucoma.

Imaging Tests

  • Types: Optical coherence tomography (OCT), Scanning laser polarimetry (GDx), and Heidelberg retinal tomography (HRT).
  • Purpose: These tests provide detailed images of the optic nerve and the retina, helping in detecting subtle changes over time.

Treatment Options for Glaucoma


Eye Drops

Prostaglandin analogues: Increase outflow of the fluid in the eye, thereby reducing IOP.

Beta-blockers: Decrease the production of fluid in the eye, resulting in improved ocular health.

Alpha agonists: Decrease fluid production and increase drainage.

Carbonic anhydrase inhibitors: Reduce fluid production.

Rho kinase inhibitors: A newer class of medication that reduces IOP.

  • Adherence: It’s essential for patients to use these medications exactly as prescribed to achieve the desired outcome.

Oral Medications

  • Usage: In cases where eye drops alone are insufficient.
  • Common Types: Carbonic anhydrase inhibitors in pill form.
  • Consideration: It may have more systemic side effects than eye drops.

Laser Therapy


  • For: Open-angle glaucoma.
  • Procedure: A laser is used to open the drainage angle, helping aqueous fluid to flow out of the eye, thereby reducing IOP.


  • For: Angle-closure glaucoma.
  • Procedure: A laser creates a small hole in the iris, allowing fluid to flow more freely and reducing the risk of sudden pressure increases.


  • Use: Reduces production of aqueous humour by treating the ciliary body with a laser.

Minimally Invasive Glaucoma Surgery (MIGS)

  • Advantages: Less invasive, reduced complications, and quicker recovery.
  • Types:
    • Microtrabecular Bypass Stents.
    • Trabecular Meshwork Bypass Devices.
    • Subconjunctival Filtration Devices.
  • Suitability: Often used in combination with cataract surgery.

Conventional Surgery


  • Procedure: Create a new drainage path to allow fluid to leave the eye.
  • Considerations: More invasive, typically reserved for advanced glaucoma or when other treatments have failed.

Glaucoma Drainage Devices (Tube Shunt Surgery)

  • Usage: In cases where trabeculectomy isn’t suitable.
  • Procedure: Implantation of a small tube to assist in fluid drainage.

Lifestyle Modifications for Glaucoma Management



Regular Exercise

  • Impact: Regular, moderate exercise like walking, jogging, or swimming can help lower intraocular pressure (IOP).
  • Recommendation: Engage in moderate physical activities for at least 30 minutes most days of the week.
  • Caution: Avoid high-impact or extreme exercises that can increase IOP, such as heavy weightlifting or high-intensity cardio.

Healthy Diet

  • Focus: Include antioxidant-rich foods in your diet, such as leafy greens, fruits, and omega-3 fatty acid-rich fish. These choices provide a myriad of health benefits to nourish your body.
  • Benefits: It may improve overall eye health and help in the management of glaucoma.
  • Suggestion: Maintain a balanced diet and stay hydrated.

Caffeine Moderation

  • Reason: Excessive caffeine can temporarily increase eye pressure.
  • Advice: Limit caffeine intake, particularly in large quantities.
