[Ocular complications inspirational and haemodialysis]

In this work, we consider the results of a study carried out in our unit about 65 dialysed chronic renal failure patients. The work is based on the study of medical records and the results of ophtalmoscopic examination and phosphocalcic balance evaluation. Ocular manifestations and their relation with initial nephropathy, dialysis and phosphocalcic disturbances are described The following alterations were observed: corneo conjunctival deposits [60%], cataract [26%], hypertensive retinopathy in 21[68%] cases among 31 [48%] who suffered from hypertension hypertensive choroidopathy in one case, vascular thrombosis in one case, diabetic retinopathy in all patients ['7] with diabetes

[Focus on the various techniques of anaesthesia in ophthalmologic surgery]

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 haeinatoma, 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 harmless. 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 still indicated in case of children
