NCT05395468

Brief Summary

The objective of our work is to predict the value of ferritin from the eye, thus constituting an original, non-invasive diagnostic method of iron deficiency. To be usable in real life, the algorithm must be comparable to the performance of the reference diagnostic test (determination of ferritin), allowing to obtain a sensitivity of about 90% and a specificity \> 95%.

Outcome Measures

Primary Outcomes (1)

  • Validate in a real clinical situation (systematic screening for iron deficiency)

    Validate in a real clinical situation (systematic screening for iron deficiency) a tool for predicting ferritin levels based on digital photographs of the ocular sclera, with confrontation of a learning base treated by deep learning, and a test base

    evaluation 15 day after diagnostic

Secondary Outcomes (2)

  • To study the informational value of photographic data

    evaluation 15 day after diagnostic

  • Identify external factors influencing the quality of the ferritin

    evaluation 15 day after diagnostic

Interventions

All subjects included will take 5 photographs of each eye according to a standardised procedure in terms of distance, lighting and framing
