Forced closure of the eyelids, or "squeezing," often with accompanying loss of vitreous, is a frequent and much dreaded complication of cataract extraction. "Squeezing" may be prevented by injections which temporarily paralyze the branches of the facial nerve which supply the muscles of lid closure. Van Lint1 was the first to publish a method of thus securing akinesis ; later, Villard,2 Wright,3 Derby4 and Robinson5 modified the original procedure. Recently, Wright advocated an entirely different type of injection.
With the exception of Wright in his latest method, all of the surgeons named make their injections at different points near the bony orbital rim. Also, in each case multiple injections are made with a long needle which traverses the tissues for some distance. This type of injection produces some bulging of the soft parts surrounding the lids, which may at times give rise to
