Eye care in intensive care in COVID-19 era: a prospective observational study from Turkey.

Abstract

There has been an increase in intensive care applications due to respiratory failure of COVID-19 infection. Management of respiratory failure includes a range of additional interventions, including high-flow nasal oxygen, noninvasive and invasive ventilation and prone position. These interventions contain risk factors for the development of ocular complications. This study aimed to elucidate the ocular pathologies that occurred in COVID-19 patients hospitalized in the intensive care unit. Patients who completed 24 hours in the intensive care unit were included in the study. Age, gender, duration of hospitalization before intensive care unit, comorbid diseases and APACHE 2 scores of COVID-19 patients admitted to intensive care unit were recorded. SOFA scores, presence of sedation and muscle relaxant, oxygen therapy (conventional oxygen therapy, high flow nasal oxygen therapy, noninvasive ventilation, invasive ventilation) and presence of prone position were recorded. All patients were evaluated daily for ocular findings. Routine eye care protocol was applied to all patients. Seventy patients were followed for a total of 596 days in the intensive care unit. Pathological ocular findings were observed during hospitalization in 59 of the patients followed. The incidence of chemosis in patients who underwent IMV was significantly higher compared to other methods (p<0.001). In this study, we observed that despite our routine eye care protocols, invasive mechanical ventilation applications predispose corneal surface damage in patients followed up in the intensive care unit with COVID-19 infection.
