Glaucoma Evaluation & Treatment

What Is Glaucoma?

Glaucoma is a group of eye diseases that damage the optic nerve. The optic nerve plays an essential role in transmitting visual signals from the retina to the brain.

In many cases, glaucoma is associated with increased intraocular pressure (IOP), which occurs when fluid inside the eye does not drain adequately. However, elevated eye pressure does not always mean a person has glaucoma, and optic nerve damage can also occur at normal pressure levels.

Glaucoma-related vision loss typically begins with peripheral vision and may gradually progress if the condition is not managed.

Because damage to the optic nerve is generally irreversible, early detection and ongoing monitoring are important.

Types of Glaucoma

Different types of glaucoma affect the eyes in different ways. Identifying the type is important for selecting an appropriate management plan.

1. Primary Open-Angle Glaucoma

Primary open-angle glaucoma is one of the most common forms of glaucoma. It develops gradually when fluid drainage within the eye becomes less efficient, leading to optic nerve damage over time.

The condition may not cause noticeable symptoms in its early stages. Regular eye examinations are important for people with risk factors.

2. Angle-Closure Glaucoma

Angle-closure glaucoma occurs when the drainage angle inside the eye becomes blocked or narrowed, preventing fluid from draining normally.

An acute angle-closure attack can cause:

• Severe eye pain

• Sudden blurred vision

• Redness of the eye

• Headache

• Halos around lights

• Nausea or vomiting

Acute angle-closure glaucoma is a medical emergency and requires immediate ophthalmic attention.

3. Normal-Tension Glaucoma

In normal-tension glaucoma, optic nerve damage occurs even though measured eye pressure remains within the statistically normal range.

This condition highlights why measuring eye pressure alone is not sufficient to rule out glaucoma.

4. Secondary Glaucoma

Secondary glaucoma develops due to another eye condition, injury, inflammation, medication use, or an underlying medical problem.

Management depends on identifying and addressing the contributing cause along with controlling eye pressure when required.

5. Congenital and Childhood Glaucoma

Childhood glaucoma is an uncommon condition that may be present at birth or develop during early childhood.

Symptoms may include excessive tearing, sensitivity to light, cloudy corneas, or unusually large eyes. Prompt assessment by an appropriate eye specialist is important.

Symptoms of Glaucoma

Many forms of glaucoma develop slowly and may not cause noticeable symptoms until significant optic nerve damage has occurred.

Possible symptoms in advanced disease include:

• Gradual loss of peripheral vision

• Difficulty seeing objects at the sides

• Tunnel vision

• Changes in visual field

• Difficulty navigating in dim lighting

Acute angle-closure glaucoma may cause sudden and severe symptoms, including eye pain, redness, blurred vision, halos around lights, and headache.

Do not wait for symptoms to appear before arranging an eye examination, particularly if you have known risk factors for glaucoma.

What Causes Glaucoma?

Glaucoma is associated with damage to the optic nerve. Several factors may contribute to the development or progression of the condition.

These include:

• Elevated intraocular pressure

• Impaired drainage of fluid inside the eye

• Family history of glaucoma

• Increasing age

• Certain anatomical features of the eye

• Previous eye injury

• Certain inflammatory eye conditions

• Prolonged or inappropriate corticosteroid use

• Some systemic health conditions

Having one or more risk factors does not necessarily mean that a person will develop glaucoma. An eye examination is required to assess individual risk.

Who Is at Risk of Glaucoma?

Some individuals may have a higher risk of developing glaucoma and may benefit from regular eye examinations.

Risk factors include:

• Age above 40 years, with risk increasing as people get older

• Family history of glaucoma

• Elevated eye pressure

• Diabetes

• Previous eye trauma

• Long-term corticosteroid use

• Certain structural features of the eye

• Existing optic nerve abnormalities

People with a family history of glaucoma should discuss an appropriate screening schedule with their eye care professional.

Glaucoma Diagnosis and Eye Examination

A comprehensive eye examination helps assess the optic nerve, eye pressure, drainage angle, and visual field.

Depending on the clinical findings, diagnostic tests may include:

1. Intraocular Pressure Measurement

Tonometry measures the pressure inside the eye. It is an important part of glaucoma assessment, but pressure measurements alone cannot confirm or exclude glaucoma.

2. Optic Nerve Examination

The optic nerve is examined to identify structural changes that may be associated with glaucoma.

3. Optical Coherence Tomography (OCT)

OCT provides detailed images of retinal nerve fibre layers and other structures around the optic nerve. It can help detect and monitor structural changes associated with glaucoma.

4. Visual Field Test

Perimetry evaluates the field of vision and can identify areas of reduced sensitivity that may be associated with glaucoma.

5. Gonioscopy

Gonioscopy allows the doctor to examine the drainage angle of the eye and helps distinguish between different types of glaucoma.

6. Corneal Thickness Measurement

Pachymetry measures corneal thickness, which is useful when interpreting intraocular pressure readings and assessing glaucoma risk.

The appropriate tests are selected based on individual clinical findings and medical history.

Glaucoma Treatment Options

Glaucoma treatment aims to reduce the risk of further optic nerve damage by controlling intraocular pressure and monitoring disease progression.

The treatment approach depends on the type of glaucoma, severity, eye pressure, optic nerve condition, and response to previous treatment.

1. Glaucoma Eye Drops

Prescription eye drops are commonly used to lower intraocular pressure. Different medications work by reducing fluid production inside the eye or improving fluid drainage.

Patients should use prescribed drops as directed and attend follow-up appointments to monitor their response.

2. Laser Treatment

Laser procedures may be recommended for selected types of glaucoma.

Depending on the condition, laser treatment may help improve fluid drainage or reduce pressure inside the eye.

The suitability of laser treatment is determined by the treating ophthalmologist.

3. Glaucoma Surgery

Surgical procedures may be considered when medications or laser treatment do not provide sufficient pressure control, or when the condition requires a surgical approach.

The type of surgery depends on the individual diagnosis and clinical assessment.

4. Regular Monitoring

Glaucoma often requires lifelong monitoring. Follow-up examinations help assess eye pressure, optic nerve health, visual fields, and treatment response.

Patients should not stop or change prescribed glaucoma medication without consulting their doctor.

Can Glaucoma Be Cured?

Glaucoma-related optic nerve damage is generally permanent and cannot be reversed. However, appropriate treatment can help slow or prevent further damage and preserve remaining vision.

Early diagnosis, adherence to treatment, and regular follow-up are important parts of glaucoma management.

Importance of Regular Glaucoma Screening

Glaucoma may progress silently, making regular eye examinations particularly important for individuals with risk factors.

A comprehensive examination can help:

• Identify early signs of optic nerve damage

• Assess intraocular pressure

• Evaluate visual field changes

• Monitor existing glaucoma

• Guide treatment decisions

• Reduce the risk of preventable vision loss

Even when eyesight appears normal, people at increased risk should discuss glaucoma screening with an eye care professional.
