Summary

Improvement of retinal medical imaging opens new perspectives for exploring the retinal structures. Optical coherence spectral domain (SD-OCT), which has been widely used in the last ten years, is certainly the most advanced device. In the analysis of patients without retinal disease using SD-OCT, granulations in the interdigitation area were observed. These granulations have never been described with this device. They could correspond either to the degradation products of the external segments of the photoreceptors or to melanosomes. A descriptive study of these granulations at different examination times and in different lighting situations would allow us to obtain essential information for a better understanding of this area. Based on the results, larger studies could explore this area more finely in retinal pathologies involving dysfunctions of photoreceptors or of the pigmentary epithelium.
