Ocular Surface Disease in a PICU: Incidence and Outcomes With a Dynamic Eye Care Protocol.

OBJECTIVES

Sedated intensive care patients have impaired ocular protective mechanisms putting them at risk for ocular surface disease with potential vision loss. Historically, routine eye care has been limited to critically ill patients receiving neuromuscular blockade. The aim of this project was to determine the occurrence rate of ocular surface disease in sedated and ventilated children, identify risk factors, and determine the progression of injury with routine eye care.

DESIGN

Prospective cohort study.

SETTING

A tertiary care medical-surgical PICU.

PATIENTS: All intubated patients admitted from May 2015 to December 2016.

INTERVENTIONS: Staff education regarding corneal examination with fluorescein, and routine eye care as per a PICU eye care protocol.

MEASUREMENTS AND MAIN

RESULTS

We evaluated 479 patients (1,242 corneal exams) and found that 15% had ocular surface disease at admission to the PICU: keratopathy 62, abrasion 16. The highest incidence was in trauma patients (39.0%) and those intubated in the emergency department (22.2%) or prehospital setting (42.9%). Of the 245 patients with multiple ocular assessments, 32.2% displayed ocular surface disease at some point during their hospitalization: keratopathy 73, abrasion 24. Ourprotocol dictated increased frequency of eye care if ocular surface disease worsened. As a result, the overall incidence of ocular surface disease decreased to 8.6% by the last examination (keratopathy 19, mild abrasion 2), but more severe ocular abnormalities such as corneal infiltrates, ulcers, or scarring were not observed. Based on multivariate analysis, clinical factors associated with increased risk of ocular surface disease included primary diagnosis, and lagophthalmos (incomplete eyelid closure).

CONCLUSIONS

Ocular surface disease is an under-recognized process in critically ill pediatric patients. A standardized and dynamic protocol may improve corneal health, which in turn may reduce injury, pain, infection, and long-term vision loss.
