Intraocular endoscopic surgery.

We have successfully used a new small endoscope in posterior segment surgery in situations where the operating microscope or binocular indirect ophthalmoscope provided an inadequate view. In this series of 18 procedures, we preformed posterior vitrectomies, removed retained foreign bodies, and reattached persistent retinal detachments. The only major complication was a retinal detachment. Learning to use a monocular system requires practice and preparation with experimental animals.
