A retrospective study has shown the association between the inflammatory bowel diseases (IBD) and the presence of a keratoconus. This new study will measure the prevalence of keratoconus and follow its activity in patients affected by IBD and followed up in hepatology-gastroenterology department at Nancy Hospital. The prevalence of keratoconus will be compared to known data of literature about general population.
The secondary purpose is to search for a relationship between the presence of a keratoconus and activity criteria of IBD.
Perspectives are a systematic screening for keratoconus in patients affected by IBD with the amelioration of the ophthalmologic care of IBD patients and confirmation of the recent hypothesis of inflammatory origin of keratoconus.
