Meibomian Gland Dysfunction (MGD)
Understanding Meibomian Gland Dysfunction (MGD)
Meibomian Gland Dysfunction (MGD) is a chronic condition affecting the meibomian glands, which produce meibum—an oily substance essential for maintaining a healthy tear film. MGD is a leading cause of dry eye syndrome, resulting from blocked gland ducts or abnormalities in meibum quality and quantity. This dysfunction can manifest as:
Hyposecretion: Insufficient meibum production, leading to dry eye symptoms.
Hypersecretion: Excessive meibum, causing inflammation and ocular discomfort.
If left undiagnosed, MGD can cause persistent irritation, blurred vision, and increased risk of ocular surface damage.
Global and Regional Impact
MGD is a widespread yet underdiagnosed condition affecting a significant portion of the population, especially in regions with high exposure to digital screens and environmental pollutants. Studies suggest that MGD prevalence ranges between 35% and 60% globally, with increasing incidence due to lifestyle changes and aging populations.
Challenges in Early Detection
Detecting and diagnosing MGD presents several challenges:
- Subjective Symptoms: Patients often misattribute symptoms like eye discomfort and dryness to environmental or lifestyle factors, delaying clinical evaluation.
- Diagnostic Inconsistencies: A lack of standardized diagnostic protocols leads to variation in detection methods and inconsistent patient outcomes.
- Complex Presentation: MGD frequently coexists with other forms of dry eye disease, requiring comprehensive assessments to differentiate and accurately diagnose.
These barriers make early and accurate identification of MGD difficult, leading to delayed treatment and worsening ocular health.

FH-POISE and MGD Detection
Our AI platform, FH-POISE, enhances MGD detection and management while delivering comprehensive, data-driven insights to support clinicians.
How FH-POISE MGD Works:
Integrated Image Insights:
Analyzes upper and lower eyelid images captured under specialized infrared illumination to assess meibomian gland function.
Automated Annotation
Identifies and marks the eyelid area (in blue) and meibomian gland area (in green), offering clear visualization of gland structures.
Key Metrics Evaluation: Measures critical parameters, including:
- Atrophy percentage (gland loss)
- Meiboscore (gland health grading)
- Gland-to-gap thickness ratio
- Gland tortuosity (structural irregularities)
These insights allow clinicians to detect early signs of MGD, monitor progression, and develop personalized treatment plans
Integrated Approach to Dry Eye Disease
By delivering advanced, automated analysis, FH-POISE empowers healthcare providers to improve diagnostic accuracy, streamline workflows, and enhance patient care for MGD and related eye conditions.
