Retinal cameras

What file formats can be used with the RetinaLyze fundus/retinal image algorithms?

The RetinaLyze algorithms currently support both .jpg/.jpeg and DICOM file types.

What type of fundus images can be used with the RetinaLyze algorithms?

Use of Macula-centered vs. ONH centered imagery

Images centered on the macula or optic nerve may be used, but each fundus camera should always be used in the same way (if RetinaLyze Glaucoma is used).

Min/max angle of view (e.g. 30-200 degrees)

The angle should be at least 30 degrees. There is no maximum angle of view.

Angle of view (Specific for RetinaLyze Glaucoma)

The image must always include the entire optic nerve. Each fundus camera should always be used with the same angular amplification.

Use of White-light/SLO imagery?

Only images obtained with conventional polychromatic white light can be analyzed. Images obtained with SLO, monochromatic lighting or confocal scanning systems should not be used.

Calibration of the RetinaLyze Glaucoma algorithm to each camera

As the RetinaLyze Glaucoma algorithm relies on colours, the algorithm must be calibrated to each fundus camera before the first use. Please contact your dealer to hear more about this procedure. 

OCT Devices

What file formats can be used with the RetinaLyze OCT algorithm?

The RetinaLyze OCT algorithm's goal is to classify all B-scans (1, 64, 96, 128 or 256) of the OCT examination by severity of pathological signs. It currently supports analysis of individual B-scans of the posterior segment.

The scans should be in .jpeg/.jpg or .png format, and named in alphabetical order (or numbered sequentially) to be displayed in the correct order on the heatmap. DICOM format is also supported.

The scans should be free of any text, technical artifacts, lines, drawings, annotations etc.

What type of OCT scans can be used with the RetinaLyze algorithms?

Use of Macula-centered, ONH centered imagery and/or Anterior segment OCT

Only scans centered on the macula may be used. The size of the macula area should be 6x6mm to 9x12mm.

The scan can include the optic nerve head, but keep in mind that that RetinaLyze OCT analyzes only the macula (the ONH will be ignored).

Only horizontal scans are supported.
