World Keratoconus Day

Picture looking at the world through a lens that blurs, clouds, and distorts everything you see. This is a daily reality for many individuals with keratoconus.⁠

Keratoconus is an eye condition that changes the shape of the clear front part of the eye, called the cornea. This makes the cornea become thinner and bulge out in a cone-like way, which can distort how you see things.⁠

November 10 is World Keratoconus Day, a global day to increase awareness and education about this condition.⁠ Connective tissue disorders have been linked to an increased risk of keratoconus as they can cause weakening of the cornea. In the 2017 Ehlers-Danlos Syndromes (EDS) International Criteria, keratoconus is described as a specific feature and complication in Brittle Cornea Syndrome (BCS) and vascular Ehlers-Danlos syndrome (vEDS). ⁠

In addition, a 2021 study, looking at genetic causes of keratoconus found abnormalities in COL5A1, TNXB, and ZNF469, all genes known to also cause EDS. In 2022, a review summarising the more common eye concerns found in EDS was published, Ehlers-Danlos syndromes and their manifestations in the visual system.
