SBM Sistemi IDRA Dry Eye Diagnostic System

SBM Sistemi is an Italian-origin, globally recognized brand that has been developing innovative products in ophthalmology since 1989. IDRA is a next-generation diagnostic system that objectively evaluates dry eye syndrome with comprehensive and rapid results.

What is IDRA?

IDRA (Interferometry Dry-eye Report and Analysis) is a fully automatic, non-invasive diagnostic system that objectively evaluates the quality and stability of the tear film. It creates the gold standard in dry eye diagnosis by measuring multiple parameters in a single device.

Why IDRA?

Limitations of Traditional Methods

• Subjective evaluation
• Observer dependent
• Repeatability issues
• Limited parameter measurement
• Invasive tests

IDRA’s Advantages

• ✓ Objective measurements
• ✓ Automatic analysis
• ✓ High repeatability
• ✓ Non-invasive
• ✓ Fast results (30 seconds)
• ✓ Multiple parameter analysis
• ✓ Detailed reporting

Parameters Measured by IDRA

1. Lipid Layer Analysis (Interferometry)

Lipid Layer Thickness

The lipid layer, the outermost layer of the tear film, prevents evaporation. IDRA measures the thickness of the lipid layer with nanometer precision using interferometry technology.

Measurement Values:

• Normal: >75 nm (Colored patterns - Grade 3-5)
• Borderline: 60-75 nm (Grey-white patterns - Grade 2)
• Abnormal: <60 nm (Grey patterns - Grade 1)
• Very thin: <30 nm (No pattern - Grade 0)

Clinical Significance:

• Meibomian gland dysfunction (MGD) diagnosis
• Evaporative dry eye assessment
• Treatment efficacy monitoring
• Lipid layer deficiency

Interferometric Patterns:

• Grade 5: Thick, bright colored patterns
• Grade 4: Medium thickness, colored-white
• Grade 3: Thin, grey-white patterns
• Grade 2: Very thin, indistinct patterns
• Grade 1: Light grey or no pattern
• Grade 0: No lipid layer

2. NIBUT (Non-Invasive Break-Up Time)

Tear Film Break-Up Time

NIBUT measures tear film stability. It automatically detects the time until the first break-up of the tear film after blinking.

Measurement Values:

• Normal: >10 seconds
• Borderline: 5-10 seconds
• Abnormal: <5 seconds
• Severe: <3 seconds

Advantages:

• Non-invasive (no fluorescein needed)
• Repeatable
• Automatic detection
• Objective measurement
• Video recording

Clinical Use:

• Tear film stability
• Evaporative dry eye
• Aqueous deficiency
• Post-LASIK evaluation
• Contact lens suitability

3. Meibography (Meibomian Gland Imaging)

Meibomian Gland Structure Analysis

IDRA evaluates the structure and atrophy of meibomian glands with infrared imaging. It objectively measures meibomian gland loss in both upper and lower lids.

Meiboscore Classification:

Upper Lid:

• Grade 0: No gland loss (0%)
• Grade 1: Mild loss (<1/3)
• Grade 2: Moderate loss (1/3 - 2/3)
• Grade 3: Severe loss (>2/3)

Lower Lid:

• Grade 0: No gland loss
• Grade 1: Mild atrophy
• Grade 2: Moderate atrophy
• Grade 3: Advanced atrophy

Clinical Value:

• MGD diagnosis and staging
• Structural assessment of glands
• Treatment planning
• Prognosis determination
• Follow-up and comparison

Imaging Features:

• High resolution
• IR (infrared) technology
• Both lids separately
• Automatic gland recognition
• Percentage loss calculation

4. Meniscus Height (Tear Meniscus Height - TMH)

Lower Lid Tear Meniscus

Measures the lower lid tear meniscus height, an indirect indicator of tear volume, with micrometer precision.

Measurement Values:

• Normal: 0.20 - 0.35 mm
• Borderline: 0.15 - 0.20 mm
• Low: <0.15 mm
• High: >0.35 mm

Clinical Meaning:

• Tear production assessment
• Aqueous deficiency diagnosis
• Tear drainage problems
• Sjögren’s syndrome
• Reflex tearing

5. Blink Analysis

Blink Frequency and Regularity

IDRA automatically analyzes blink frequency and regularity during video recording.

Normal Values:

• Frequency: 10-20 blinks/minute
• Complete blink rate: >80%
• Partial blink: <20%

Clinical Use:

• Blink disorders
• Screen usage effects
• Neurological conditions
• Patients requiring education

6. Redness Analysis

Conjunctival and Limbal Hyperemia

Objectively measures and grades vascular engorgement in bulbar conjunctiva and limbal region.

Grading:

• Grade 0: No redness
• Grade 1: Mild (+)
• Grade 2: Moderate (++)
• Grade 3: Severe (+++)
• Grade 4: Very severe (++++)

Regions:

• Nasal conjunctiva
• Temporal conjunctiva
• Limbal area
• Total hyperemia score
