1. A tapeto-retinal degeneration can be observed in association with a disturbance in the metabolism of the lipids.
2. This fact gives a new argument in favor of the hypothesis that the tapeto-retinal degeneration is due to a metabolic alteration and more probably to an enzymatic disturbance in the sensorial epithelium of the retina.
3. The investigations of Hooft et al (1962) demonstrate that it may be an insufficiency of the pyridine nucleotide coenzymes following a primary disturbance in the metabolism of tryptophane.
4. In a case of pigmentary retinopathy, it is now indispensable to do a systematic blood examination both on the morphological and on the biochemical and metabolic point of view.
