    Abstract:
    OBJECTIVE: To describe the demographic features of a large series of patients with floppy eyelid syndrome (FES) and to investigate the associations of the condition with keratoconus, obstructive sleep apnea-hypopnea syndrome (OSAHS), and a variety of upper and lower eyelid features. DESIGN: Case control study. PARTICIPANTS: The test group comprised 102 patients with FES. A control group of 102 patients were recruited from a diabetic retinopathy clinic and matched on a 1:1 basis on age, gender, and body mass index (BMI). METHODS: A full medical and ophthalmic history was taken. Patients also underwent a full ocular examination, including an assessment of upper and lower lid laxity and upper lid levator function. Keratoconus grading was made using the Oculus Instruments Pentacam imaging system (Oculus Optikgerate GmbH, Wetzlar, Germany). Patients were screened for OSAHS using the Epworth daytime somnolence score. Matched statistical analysis of dichotomous data was made using Mantel-Haenszel methods for odds ratios and McNemar's test. Analysis of continuous data was performed using a matched t test and tests for symmetry of larger tables were made using the McNemar-Bowker test. MAIN OUTCOME MEASURES: The significance of association of FES with keratoconus, OSAHS, smoking history, medial and lateral canthal laxity of the upper and lower lids, levator function, lash ptosis, and dermatochalasis. RESULTS: Significant associations were found between FES and OSAHS (P = 0.0008), keratoconus (P<0.0001), lash ptosis (P<0.0001), dermatochalasis (P = 0.02), upper lid medial canthal laxity (P = 0.02), upper lid distraction (P = 0.001), palpebral aperture (P = 0.004), and levator function (P = 0.005). CONCLUSIONS: Floppy eyelid syndrome seems to be a condition strongly associated with OSAHS and keratoconus. As well as providing a platform for an etiologic hypothesis for the condition, these findings should also encourage clinicians to be aware of these associations and to direct further treatment.
