Epidemiology, economic and humanistic burdens of Ocular Surface Chemical Injury: A narrative review

Ocular surface chemical injury (OSCI) is a common type of ocular emergency that can potentially cause significant and permanent visual impairment. However, the global prevalence, demographic factors, socioeconomic burden, and psychological impact of OSCI have not been well investigated or reported. This review aims to provide a comprehensive overview of these aspects, highlight gaps in the literature, and advocate key strategies in reducing the incidence of OSCI. OSCI was responsible for 0.1-15% of all ocular emergency presentations, with an estimated incidence of 5.1-50 per 100,000 population-year. Young working adult men were the most at-risk group, though high rates of OSCI were also observed in young children in developed countries, especially from detergent pods. Low- and middle-income countries were noted to have higher proportions of assault-related and pediatric OSCI cases, often with more severe presentations. Direct and indirect costs for some hospitalized patients led to loss of all personal and household income after the injury. Emergency department costs in the United States were estimated at $106.7 million over four years and costs of treating long term complications such as glaucoma were estimated to be as high as $93,003 over five years. Significant negative impacts on visual and health-related quality of life and psychological well-being have been reported after injury, with higher rates of anxiety, depression, and psychological distress compared to the general population.

Acute and Chronic Ophthalmic Involvement in Stevens-Johnson Syndrome/Toxic Epidermal Necrolysis - A Comprehensive Review and Guide to Therapy. II. Ophthalmic Disease

Our purpose is to comprehensively review the state of the art with regard to Stevens- Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), with particular attention to improving the management of associated ocular surface complications. SJS and TEN are two ends of a spectrum of immune-mediated disease, characterized in the acute phase by a febrile illness followed by skin and mucous membrane necrosis and detachment. Part I of this review focused on the systemic aspects of SJS/TEN and was published in the January 2016 issue of this journal. The purpose of Part II is to summarize the ocular manifestations and their management through all phases of SJS/TEN, from acute to chronic. We hope this effort will assist ophthalmologists in their management of SJS/TEN, so that patients with this complex and debilitating disease receive the best possible care and experience the most optimal outcomes in their vision and quality of life.
