Keratoconus caused by eye rubbing in patients with Tourette Syndrome.
OBJECTIVE: To report the association between keratoconus and Tourette Syndrome (TS) and to reinforce that eye rubbing may be a causative factor for keratoconus.
DESIGN: Observational case series.
PARTICIPANTS: Three patients with TS who presented with clinical and topographic findings suggestive of asymmetric or unilateral keratoconus.
METHODS: Evaluation of patients in a single clinical practice.
RESULTS: Patients' histories revealed asymmetric or unilateral rubbing of the affected eye as a result of a TS tic. Other organic causes associated with keratoconus were absent in these patients.
CONCLUSIONS: A possible association between TS and keratoconus exists with chronic eye rubbing being the suggested mechanism. Eye rubbing seems to be an important causative factor for keratoconus.
