SBM Sistemi IDRA Dry Eye Diagnostic Platform

The SBM Sistemi IDRA is a comprehensive ocular-surface diagnostic platform developed for rapid, detailed and noninvasive assessment of tear-film composition.

Its multimodal camera combines color imaging, near-infrared sensitivity and yellow-filtered acquisition with infrared, blue, red and white LED illumination. Two imaging cones—the main cone and Placido cone—support the different examinations available within the platform.

Depending on the selected software configuration, IDRA can evaluate tear-film lipid patterns, tear-meniscus height, noninvasive tear-breakup time, meibomian glands, blink quality, eyelid margins, bulbar redness, pupil diameter and white-to-white corneal diameter.

Automatic tools assist with NIBUT measurement, tear-film stability mapping, tear-meniscus measurement and, in the Full configuration, lipid-layer interferometry. The system also captures images and videos that facilitate documentation, patient education and comparison during follow-up.

IDRA is available in Basic, Plus and Full configurations. The exact examinations and automation features included depend on the purchased license.
