Summary
In the present paper we have studied the gross (mesoscopic) anatomy of the ophthalmic a. in humans, using magnification by microsurgical systems to obtain data on the origin and course of this artery and its main collateral branches. Comparison of our results with previous reports indicates that, although the anatomical variations of the vascular system are well known, some patterns of frequency may be emphasised. Thus, the ophthalmic a. was usually found as a collateral branch of the internal carotid a., although other origins were also found. The ophthalmic a., once inside the orbit, followed a course above the optic nerve in most cases. All the collateral branches of the ophthalmic a., with the exception of the muscular branches, showed great constancy.
Résumé
Dans cette étude nous avons étudié l'anatomie macroscopique (mésoscopique) de l'a. ophtalmique chez l'homme. Grâce au microscope et aux outils micro-chirurgicaux, nous avons pu obtenir des données sur l'origine et le trajet de cette artère et de ses principales branches collatérales. Nous avons comparé nos rśultats aux données précédemment rapportées et avons conclu que certains points pouvaient être mis en relief, malgré la diversité bien connue des variations anatomiques du système vasculaire. Ainsi l'a. ophtalmique apparaît habituellement comme une branche collatérale de l'a. carotide interne, bien que d'autres origines de cette artère aient été retrouvées. L'a. ophtalmique, dans son trajet intra-orbitaire, suit un trajet situé au dessus du n. optique dans la plupart des cas. Toutes les branches collatérales de l'a. ophtalmique, à l'exception des branches musculaires, présentent une grande constance.
