The use of non-invasive ventilation (NIV) devices such as continuous positive airway pressure and bi-level positive airway pressure machines have been associated with an increased incidence of dry eye disease (DED). To understand how the use of these ventilation masks impacts the eyes, a review of the pathophysiology of DED and an evaluation of recent studies investigating the effects of NIV use on the severity and incidence of this condition were performed. It was found that the use of face masks associated with the ventilation devices exhibited a positive correlation to the incidence and severity of numerous ocular pathologies. However, the benefits of non-invasive mechanical ventilation are undeniable in treating conditions such as obstructive sleep apnea, chronic obstructive pulmonary disease, and respiratory failure; therefore, proper education, behavioral modifications, and treatment can help reduce or prevent the adverse effects that NIV have on the eyes.
