Glaucoma Screening
Harley Street, London
Glaucoma screening represents one of the most important investments you can make in your long-term vision health. This comprehensive evaluation process identifies the earliest signs of glaucomatous damage, often years before you might notice any vision changes. Miss Shreya Haldar’s advanced screening programme combines cutting-edge diagnostic technology with expert clinical assessment to provide the most thorough glaucoma evaluation available in London.
The devastating reality of glaucoma is that once vision is lost, it cannot be recovered. However, when detected early, glaucoma progression can be slowed or halted with appropriate treatment, preserving sight for a lifetime. Regular screening is particularly crucial because glaucoma often develops without symptoms until significant damage has already occurred.
Understanding the Need for Screening
Glaucoma affects over 700,000 people in the UK, yet it’s estimated that half of those with the condition remain undiagnosed. This “silent thief of sight” earns its nickname through its ability to cause irreversible vision loss without warning symptoms. The peripheral vision loss that characterises early glaucoma often goes unnoticed as the brain compensates for these blind spots.
By the time patients become aware of vision problems, substantial optic nerve damage has typically occurred. Studies show that patients can lose up to 40% of their optic nerve fibres before developing noticeable visual field defects. This underscores the critical importance of regular screening, particularly for those at higher risk.
The good news is that glaucoma, when detected early, responds well to treatment. Modern therapies can effectively slow or halt disease progression, preserving functional vision throughout a patient’s lifetime. However, this success depends entirely on early detection through comprehensive screening.
Who Needs Glaucoma Screening?
While everyone benefits from regular eye examinations that include glaucoma assessment, certain individuals require more frequent and comprehensive screening due to increased risk factors.
Age-Related Risk
Age is the most significant risk factor for glaucoma development. The condition becomes increasingly common after age 40, with risk doubling every decade thereafter. By age 80, glaucoma affects approximately 10% of the population. This age-related increase makes regular screening essential for everyone over 40, with more frequent examinations recommended as age increases.
Family History
Genetics plays a crucial role in glaucoma risk. First-degree relatives of glaucoma patients have a four to nine times higher risk of developing the condition. This genetic predisposition means that family members should begin screening earlier and undergo more frequent examinations than the general population.
Ethnic Background
Certain ethnic groups face significantly higher glaucoma risks. People of African descent have a six times higher risk of developing primary open-angle glaucoma and tend to develop it at younger ages with more rapid progression. Asian populations have increased susceptibility to angle-closure glaucoma. These elevated risks necessitate earlier and more frequent screening.
Medical Conditions
Several medical conditions increase glaucoma risk, including diabetes, high blood pressure, heart disease, and thyroid disorders. Patients with these conditions benefit from enhanced glaucoma surveillance as part of their overall eye care.
Previous Eye Problems
Any history of eye injury, surgery, or other eye conditions can predispose to glaucoma development. Patients with high myopia (short-sightedness) also face increased glaucoma risk and require regular monitoring.
Comprehensive Screening Process
Miss Haldar’s glaucoma screening programme employs multiple diagnostic modalities to provide the most comprehensive assessment possible. This multi-faceted approach ensures that subtle signs of glaucomatous damage are detected at the earliest possible stage.
Medical History and Risk Assessment
The screening process begins with a detailed medical history that identifies risk factors and symptoms. This includes family history of glaucoma, previous eye problems, current medications, and any symptoms that might suggest glaucomatous damage.
Understanding your individual risk profile helps guide the screening process and determines appropriate follow-up intervals. Patients with multiple risk factors require more intensive screening protocols.
Intraocular Pressure Measurement
Measuring intraocular pressure (IOP) remains a cornerstone of glaucoma screening. Miss Haldar uses advanced tonometry techniques to obtain accurate pressure readings. However, it’s important to understand that normal pressure doesn’t rule out glaucoma, as normal-pressure glaucoma can occur.
Pressure measurements are interpreted in the context of other findings and individual risk factors. Some patients can tolerate higher pressures without damage, whilst others develop glaucomatous changes at statistically normal pressures.
Optic Nerve Assessment
Direct examination of the optic nerve provides crucial information about glaucomatous damage. Miss Haldar performs detailed ophthalmoscopy to assess the optic disc appearance, looking for signs of cupping, rim thinning, and other structural changes that indicate glaucomatous damage.
Advanced optic nerve photography creates a permanent record of the optic disc appearance, allowing for precise monitoring of changes over time. This documentation is invaluable for detecting subtle progression that might otherwise go unnoticed.
Optical Coherence Tomography (OCT)
OCT represents a revolutionary advance in glaucoma detection, providing detailed cross-sectional images of the optic nerve and retinal nerve fibre layer. This technology can detect structural changes before functional vision loss occurs, enabling earlier treatment initiation.
The quantitative nature of OCT measurements allows for precise monitoring of disease progression. Subtle changes in nerve fibre layer thickness can be detected and tracked over time, providing objective evidence of disease stability or progression.
Visual Field Testing
Automated perimetry maps the complete visual field, identifying areas of vision loss that indicate functional damage from glaucoma. Modern visual field testing provides reliable, reproducible measurements that are essential for diagnosing and monitoring glaucoma.
The characteristic pattern of visual field loss in glaucoma helps distinguish it from other conditions that might affect vision. Regular visual field testing tracks disease progression and guides treatment decisions.
Gonioscopy
This specialised examination evaluates the drainage angle structure, determining whether the angle is open or narrow. Gonioscopy is essential for identifying patients at risk for angle-closure glaucoma and guides treatment decisions for different types of glaucoma.
The examination involves using a special lens to visualise the angle structures directly. This assessment helps determine the type of glaucoma present and influences treatment approaches.
Advanced Imaging Techniques
When indicated, additional imaging studies provide further insight into glaucoma risk and damage. These might include anterior segment OCT for detailed angle analysis or other specialised imaging techniques for complex cases.
Interpreting Screening Results
Glaucoma screening results must be interpreted by an experienced ophthalmologist who can integrate findings from multiple tests and consider individual risk factors. No single test definitively diagnoses glaucoma; rather, the diagnosis emerges from the pattern of findings across all assessments.
Normal Results
Normal screening results provide reassurance but don’t eliminate the need for ongoing surveillance. Glaucoma can develop at any time, and risk factors may change. Regular screening intervals are maintained based on individual risk profiles.
Suspicious Findings
Some screening results fall into a grey area where glaucoma cannot be definitively diagnosed but cannot be ruled out either. These patients require closer monitoring with more frequent examinations and additional testing as needed.
This “glaucoma suspect” category is important because it identifies patients who may be in the earliest stages of disease development. Close monitoring allows for prompt treatment initiation if glaucoma develops.
Positive Results
When screening identifies definitive signs of glaucomatous damage, comprehensive evaluation determines the extent of disease and guides treatment planning. Early detection at this stage still offers excellent opportunities for preserving remaining vision through appropriate treatment.
Screening Frequency Recommendations
The frequency of glaucoma screening depends on individual risk factors and previous results. Miss Haldar provides personalised recommendations based on your specific situation.
Low-Risk Individuals
People without significant risk factors typically require comprehensive eye examinations every two to three years after age 40, increasing to annual examinations after age 65.
Higher-Risk Individuals
Those with family history, ethnic risk factors, or other predisposing conditions may require annual or more frequent screening beginning at younger ages.
Glaucoma Suspects
Patients with suspicious findings require more frequent monitoring, often every six months, to detect any progression that would warrant treatment initiation.
The Benefits of Early Detection
Early glaucoma detection provides numerous advantages that significantly impact long-term visual outcomes. Treatment initiated in the early stages is more likely to successfully preserve vision throughout a patient’s lifetime.
Early-stage glaucoma typically responds well to less aggressive treatments, often requiring only topical medications or laser therapy. This contrasts with advanced cases that may require complex surgical interventions.
Patients diagnosed early have more treatment options available and greater flexibility in managing their condition. They also have more time to adapt to their diagnosis and develop effective management strategies.
