[Changes in the retinal vessels in mandibular nerve anesthesia. A potential for complications]

Examinations of the eyegrounds were made on thirty subjects after conduction anesthesia with xylocitin of the inferior alveolar nerve as well as on nine subjects after sodium chloride injections in order to determine the effect of mandibular conduction anesthesia on retinal vessels. Retinal vascular widths were measured and arteriovenous indices determined. The subjects were divided into groups according to preexisting general diseases, age, sex, and smoking habits. Retinal vascular changes were determined in dependence on age and smoking habits after injections made into the mandibular foramen, and the manner of origin and the results are discussed with particular reference to data reported in the literature.
