Prevalence of Keratoconus in Inflammatory Bowel Diseases (OSCAR)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02861339
Recruitment Status : Completed

Central Hospital, Nancy, France

Brief Summary:

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.
