Risk factors for keratoconus
To evaluate the risk factors associated with keratoconus in a case-control setting, Moran et al followed 202 patients with keratoconus and 355 controls in this prospective, single-centre, case-control study. Data on multiple variables were gathered, including eye rubbing, pattern of eye rubbing, dominant hand, allergies, history of dry eye, screen time, sleep position, and night-time work. The authors find a strong correlation between eye rubbing and keratoconus, particularly when rubbing is performed with the knuckles.
