Background: To determine if fine-motor eye exercises can be used for treatment of unilateral, idiopathic cranial nerve VII paresis to improve rate of recovery. Methods: In this prospective, randomized controlled trial, eligible patients were randomized to perform fine-motor eye exercises (n=18) or to do no exercise (n=9) for a period of four weeks. Orbicularis oculi muscle strength was measured in paretic and unaffected eyes at baseline, two weeks and four weeks using an Orbicularis Oculi Pressure Sensor. Results: The average initial strength of the paretic orbicularis oculi muscle was 34±10 mm Hg compared to the unaffected muscle which was 103±17 mm Hg at baseline (n=27). By four weeks, patients who performed eye exercises improved more than those who did not (74.4 versus 47.4 mm Hg, p=0.029). While there was some loss to follow-up, 63.8% of patients performing exercises (7/11) achieved functional recovery at four weeks compared to 12.5% (1/8) of those who did not (p=0.059). Steroids and antivirals were found to have independent positive effects on improving functional outcome. Conclusions: Eye exercises have a potential role in the treatment of idiopathic cranial nerve VII paresis and warrant consideration in the management of these patients.
