Common ocular surface disorders in patients in intensive care units

Abstract

Ocular surface disorders are frequently encountered in patients in Intensive Care Units (ICUs). Because of significant impairment of major organs, treatment is focused on the management of organ failures. Therefore, ophthalmological complications are frequently overlooked in this setting. To identify the types and frequencies of ocular surface disorders reported in patients in ICUs, a literature review using the keywords: Intensive Care; Eye care; ICU; ITU; Ophthalmological disorders; Eye disorders was performed. The databases of CINAHL, PUBMED, EMBASE and COCHRANE library were searched. The higher quality papers are summarized in tables with statements of methodology to clarify the level of evidence. The most prevalent ocular disorders identified in ICU patients were exposure keratopathy (3.6% to 60%), chemosis (9% to 80%), and microbial keratitis. Of the various eye care measures that have been advocated to prevent exposure keratopathy, the most effective is the application of moisture chambers or polyethylene covers. Early diagnosis and effective treatment will help to prevent microbial keratitis and visual loss.
