Ocular Surface Disorders in Intensive Care Unit Patients

الملخص EN

Patients in intensive care units (ICU) are at increased risk of corneal abrasions and infectious keratitis due to poor eyelid closure, decreased blink reflex, and increased exposure to pathogenic microorganisms.

The aim of this retrospective study was to evaluate the ocular surface problems in patients who stayed in ICU more than 7 days and were consulted by an ophthalmologist.

There were 26 men and 14 women with a mean age of 40.1 ± 18.15 years (range 17–74 years).

Conjunctiva hyperemia, mucopurulent or purulent secretion, corneal staining, and corneal filaments were observed in 56.25%, 36.25%, 15%, and 5% of the eyes, respectively.

Keratitis was observed in 4 patients (10%) who were treated successfully with topical antibiotics.

Mean Schirmers test results were 7.6 ± 5.7 mm/5 min (median 6.5 mm/5 min) in the right, and 7.9 ± 6.3 mm/5 min (median 7 mm/5 min) in the left eyes.

Schirmers test results were <5 mm/5 min in 40% of the subjects.

The parameters did not show statistically significant difference according to mechanical ventilation, sedation, and use of inotropes.

As ICU patients are more susceptible to develop dry eye, keratopathy, and ocular infections, they should be consulted by an ophthalmologist for early diagnosis of ocular surface disorders.
