Does Eye Rubbing Cause Keratoconus?
May 6, 2014
Ideally, the cornea should be spherical, but in some patients the cornea gets deformed to a cone shape – a condition known as keratoconus. Keratoconus may cause blurring of vision which may require the use of a rigid contact lens or surgical intervention.
It’s been thought that eye rubbing – a behavior very common in patients with eczema and other chronic allergic conditions – when done constantly every few minutes over many years may lead to permanent changes to corneal curvature leading to keratoconus.
There is now a study in the United Kingdom recruiting participants that will study the question of changes in the shape of the cornea from eye rubbing.
