Cyclopentolate-phenylephrine eye drops are commonly used for mydriasis during routine screening for retinopathy of prematurity in preterm infants. Although systemic absorption is minimal, it can result in side effects. We report two cases of transient paralytic ileus associated with transient oxygen desaturation and hypertension following the use of cyclopentolate-phenylephrine eye drops.

Cyclopentolate is a synthetic anti-cholinergic agent widely used in ophthalmology clinics. It can cause cardiovascular side-effects such as hypertension, ventricular arrhythmias and tachycardias. A 55-year-old male lost his consciousness after topical cyclopentolate hydrocloride (1%) administration for routine fundoscopic examination in another center. An urgent cranial magnetic resonance imaging examination revealed a midbrain hemorrhage and he was transferred to our hospital. The Glasgow Coma Scale score was at 4 points at admission. The patient was transferred to the intensive care unit and mechanically ventilated. Despite vigorous medical treatment, spontaneous respiration and brainstem reflexes disappeared 12 h after his administration. A control cranial computerized tomography showed enlargement and opening of the hemorrhage into the ventricular system. The patient died on the 12th day of his administration. Systemic side-effects of topical ocular cyclopentolate administration and prevention methods were discussed with regard to the current literature.
