Lacrimal canaliculoscopy: development of the instrument

We have developed an endoscopic device for use in the lacrimal drainage system. The device employs a flexible, small-calibre fibreoptic cable that can easily negotiate the canalicular system. The device can be used in conjunction with a video camera and monitor for simultaneous viewing. The endoscope can be used alone for the diagnosis of lacrimal disorders. Possible future applications include laser treatment of lacrimal disorders.
