The lax eyelid syndrome

The floppy eyelid syndrome (FES) was first described in middle aged, obese men. In later descriptions, age and sex were not specifically mentioned. Associations of FES with various other syndromes have been described. The authors question whether all these cases represent the same, single, syndrome. They suggest that a clinical picture similar to FES may occur in lax upper eyelids of any cause. Four such cases are reported here. The authors therefore coin the more general term 'lax eyelid syndrome'. They suggest using the term 'floppy eyelid syndrome' uniquely for patients with the classic signs and symptoms.
