[THE GUT FEELING OF THE EYES: GUT-EYE AXIS].

In intestinal diseases there are ophthalmological abnormalities. In celiac disease, for example, the eyes' pathologies are expressed by motoric, neurological, inflammatory, autoimmune, vision sharpness, dryness, redness, conjunctivitis and cataract tendency etc. It appears that intestinal luminal components and processes can irradiate to peripheral organs, including to the eyes, inducing functional abnormalities in this target organ. The present review describes the luminal and mucosal constituents and processes, the sensing mechanisms of those generated signals and the routes to deliver those messages to remote organs, eyes included. The gut-eye axis is very challenging and its exploration might bring future therapeutic strategies to treat ophthalmological disease.
