Chronic Blepharitis: Review of incidence, prevalence and treatments

According to statistical data, Chronic Blepharitis has the highest incidence of eye diseases. In a survey conducted in the United States (USA), 37% to 47% of patients seen by respondents were diagnosed with blepharitis. In 2014, blepharitis accounted for 700,000 patient visits in the USA. There are few epidemiological data estimate that the true prevalence of blepharitis. In the past, there has been considerable confusion over the pathophysiology, and thus the definition of blepharitis. Because of these uncertainties, an accurate assessment of the prevalence and incidence of the disease has been difficult to achieve. The objective of this study was to review the literature to present and contribute to the readers information on the incidence and prevalence of chronic blepharitis in the world, and to identify the best medical treatments and interventions. Based on the literature review, there are still many information gaps regarding the best treatment for chronic blepharitis as well as dysfunction of Meiobomio gland (DMG). In conclusion, it is imperative to create multicenter randomized studies to better understand what is the best treatment for these diseases in order to at least ensure improved quality of life throughout the entire treatment.
