Key definitions

OCTOptical coherence tomography (OCT) is a non-invasive imaging test. OCT uses light waves to take cross-section images of the retina
ExaminationUploaded Horizontal B-Scans between 6-12 mm
Retina Layers SegmentationAltris AI segments 10 retinal layers and you can explore each one of them separately
Retina ThicknessAltris AI system calculates the thickness of each retinal layer or of several layers combined
Scan Quality ClassificationAltris AI detects low-quality scans automatically and warns about the possibility of poor quality scans affecting the analysis
Segmentation and ClassificationAI algorithm detects and segments pathologies and classifies diseases

Types of severity:
Quality or state of being severe
Normal retina (Green):Normal structure of retinal layers

Posterior hyaloid detachment or its adhesion without any changes in retinal layers

In these cases, best corrected visual acuity (BCVA) is usually normal
Moderate Severity (Yellow):Conditions with normal BCVA or slight deviation from it

Decreased BCVA

Minor pathologies in retinal layers, such as RPE disruption, single hard drusen, areas of epiretinal fibrosis without structural retinal changes, floaters, myopia, small changes in parafoveal zone

Conditions with medium changes in retinal layers

Conditions that need treatment and follow up (epiretinal membranes, mild DRP, soft or confluent drusen, diffuse macula edema, etc.)
Severe (Red):Conditions with significant changes in retinal layers


Sight tthreatening conditions (retinal detachment, exudative AMD, geographic Atrophy, macular holes, etc.)
