Why a Slit Lamp Examination is Essential for Dry Eye Diagnosis
Dry eye is a complex, multifactorial condition, and effective treatment depends on understanding exactly what is driving your symptoms.
Our high-resolution slit lamp allows us to assess:
- Tear film quality and stability
- Corneal and conjunctival health
- Eyelid margins and meibomian gland function
- Signs of inflammation, blepharitis, or ocular surface damage
This level of precision enables our clinicians to move beyond generalised treatments and develop a bespoke treatment plan tailored to your specific condition.
Fluorescein Dye: Assessing Tear Film Stability
As part of your dry eye assessment in the UK, we use fluorescein dye to evaluate how well your tear film is functioning.
This is particularly important in diagnosing evaporative dry eye and tear film instability, one of the most common causes of symptoms.
Fluorescein allows us to:
Tear Break-up Time
Measure tear break-up time (TBUT) – how quickly tears evaporate.
Identify Dryness & Damage
Identify dry spots and microscopic corneal damage.
Tear Coating
Assess how evenly your tears coat the eye surface.
Lissamine Green: Detecting Ocular Surface Damage
We also use lissamine green dye, which highlights areas of stressed or damaged cells on the surface of the eye.
Lissamine green is especially valuable in diagnosing chronic and more advanced dry eye conditions, ensuring nothing is overlooked.
This enables us to:
Detect Early-stage Dry Eye Disease
Identify Inflammation and Surface Damage
Grade the Severity of Ocular Surface Disease
See What We See: High-Definition Video Imaging
At Dry Eye Centre, our advanced slit lamps are equipped with high-definition video capture technology.
This allows us to:
Show you real-time images of your eye surface.
Clearly explain what is causing your symptoms.
Document findings to track your progress over time.
Help you better understand your diagnosis and treatment plan
We believe that informed patients achieve better outcomes. By visually guiding you through your assessment, we provide a transparent, educational, and reassuring clinical experience.
Personalised Dry Eye Treatment Starts with Accurate Diagnosis
By combining slit lamp biomicroscopy, fluorescein and lissamine green staining, and digital imaging, we deliver one of the most comprehensive dry eye assessments in the UK.
This detailed approach allows us to:
- Identify the root cause of your symptoms
- Detect issues early, before they worsen
- Provide targeted, evidence-based treatments
- Monitor your response and refine your care over time
