[Blood vessel preservation in squint surgery].

The vascularization of the anterior section of the bulb depends partially on the anterior ciliary vessels. Circulatory disorders of the anterior uvea have been detected following conventional squint surgery in which several of these vessels were severed, even though there were no clinically detectable symptoms. It therefore makes good sense to spare the muscular and anterior ciliary vessels as far as possible, in order to preserve the muscles themselves and the anterior section of the bulb (a) by careful surgery and (b) by adopting surgical procedures in which the vessels are not sacrificed. In the final analysis, complete preservation of the vessels can only be achieved using the operating microscope.
