Association between oral fluoroquinolone use and lateral canthal tendon rupture: case report.

It is well established and documented that fluoroquinolone use is associated with the development of tendinopathy. However, little is known about the possible effects of this class of antibiotics on the orbit. We present a case of lateral canthal tendon rupture that presented with an acute right lower eyelid ectropion in a young, renal compromised patient in the setting of recent fluoroquinolone use for pneumonia. Eye care clinicians need to be aware of the possible effects of fluoroquinolones on the eyelids.
