title: [Focus on the various techniques of anaesthesia in ophthalmologic surgery].
abstract: Ophthalmologic surgery is not a vital one. It mostly concerns patients in extreme ages: children and old people. The risk of anaesthesia mainly depends on the health conditions of the patient. General anaesthesia through use of intravenous drugs alters the balance of the endocrine and sympathetic systems. Tracheal airway intubation constitutes an added constraint and stress especially for the vascular system. Retrobulbar anaesthesia is not devoid of risks: ptosis, diplopic, orbit haematoma, lesion of the optic nerve, eye perforation, vascular occlusion, intra arterial injection, neurologic and cardiovascular toxic effects of local anaesthetics, are all ever present risk Topical anaesthesia with its various variants (single topic or associated with intracameral injection, subconjunctival, circumferential perilimbal, subtenon) represents an interesting alternative for it is simple, less toxic and harless. In our experience, this method is indicated in surgery of eye's anterior segment. We find it safe, efficacisious and economical. Regional anaesthesia is preferred to general anaesthesia especially in the surgery of dacryocystitis and ptosis. General anaesthesia in stell indicated in case of children.
