Floppy eyelid syndrome associated with keratoconus

Keratoconus has been associated with various ocular and systemic disorders. It has been linked, in a few cases, with floppy eyelid syndrome (a disorder characterized by a soft rubbery upper tarsus, papillary conjunctivitis and obesity). A 40-year-old male presented with a complaint of gradually decreasing vision in the right eye. An intermittent right exotropia had become constant and he was unable to maintain fixation voluntarily. Corneal findings were consistent with keratoconus. Floppy eyelid syndrome was also diagnosed. An underlying connective tissue disorder may link these two disorders.
