Core Tip
Core tip: Functional epiphora is a clinical condition which is not due to an anatomic defect, and the cause of functional epiphora is not very clear. In this study, we used electromyography as a valuable tool to evaluate the orbicularis oculi muscle, and the results suggest neurogenic muscle motor neuron disease in functional epiphora patients. This study reveals a possible new approach for the treatment of functional epiphora.
