Abstract Purpose Anecdotal evidence suggests that eyelid disorders are common, although estimates of prevalence vary. The current study determines the prevalence of eyelid disorders, meibomian gland dysfunction (MGD) and related diseases (specifically ocular surface disease) in a population of patients presenting for routine ophthalmologic consultations. Methods This cross-sectional epidemiologic survey evaluated patients presenting for routine ophthalmic visits. During the consultation an ophthalmologist completed a questionnaire, and each patient underwent an ophthalmic examination and completed a quality of life questionnaire. Results Three hundred forty-nine ophthalmologists, recruited from 11 countries, provided data on 6525 patients. Patients were predominantly females (61.6%). The mean age of the study population was 57.0 ± 17.6 years. Eyelid disorders were diagnosed in 5109 (78.3%) patients and were statistically associated with: atopic dermatitis, seborrheic dermatitis, dry eye, age-related macular degeneration, diabetes, cataract, allergy and MGD (P

Disease severity, tear break-up time (TBUT), tolerability, and change in clinical symptoms were recorded at baseline and at final visit (2 to 4 weeks after first treatment).Results: The severity of KCS was mild in 18.6%, moderate in 59.9%, and severe in 21.5% of patients based on physicians’ assessment. TBUT was measured in 4,338 patients before switching to or initiating therapy with Optive and at final visit. Baseline measurement of mean TBUT was 7.7 ± 3.9 seconds. This value increased to 10.0 ± 4.7 seconds at final visit. Most patients (85.4%) reported improvement in local comfort. The majority (75.1%) of patients felt an improvement in symptoms after changing their treatment. Two percent of patients reported adverse events, and 0.4% were treatment-related.Conclusions: Optive was well tolerated and improved the symptoms of dry eye after 2 to 4 weeks.Keywords: keratoconjunctivitis sicca, dry eye, sodium carboxymethylcellulose, glycerol, OptiveTM
