1/5. Transient blindness following epidural analgesia.A 43-year-old woman was given an epidural injection of steroid mixed with local anaesthetic, under general anaesthesia, for treatment of low back pain. In the recovery room she complained of blindness in one eye. Fundoscopy revealed retinal and vitreous haemorrhages in both eyes. Retinal haemorrhages can be caused by an increase in intracranial pressure and are therefore a possible complication of epidural anaesthesia.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/5. Perforation of the globe--a complication of peribulbar anaesthesia.Peribulbar anaesthesia has been recommended as a safer alternative to retrobulbar anaesthesia. We report a case of perforation of the globe sustained during peribulbar anaesthesia which resulted in blindness. Orbital injections are potentially dangerous, be they peribulbar or retrobulbar. To minimise the risk, short, blunt needles are advocated for the peribulbar route.- - - - - - - - - - ranking = 3.5keywords = anaesthesia (Clic here for more details about this article) |
3/5. Painless loss of vision after transurethral resection of the prostate.A 74-year-old man developed complete loss of vision after transurethral prostatectomy under spinal anaesthesia. Eyesight returned to normal over the next 12 hours. A direct inhibitory effect on the retina caused by glycine absorbed with the irrigation fluid is suggested as a possible cause.- - - - - - - - - - ranking = 0.5keywords = anaesthesia (Clic here for more details about this article) |
4/5. Transient unilateral blindness following general anaesthesia: case report.A case is reported of transient unilateral blindness following general anaesthesia with a face mask. The most likely explanation for this is central retinal artery occlusion, either partial or complete, due to excessive pressure from the mask exerted on the globe. This pressure may be increased with the use of neoprene head straps as opposed to the more flexible and elastic rubber straps. Pressure from the strap over the carotid artery may be a factor in reducing the central retinal arterial pressure, thus making it more susceptible to occlusion by mask pressure.- - - - - - - - - - ranking = 2.5keywords = anaesthesia (Clic here for more details about this article) |
5/5. Caesarean section following a recent retinal haemorrhage.We report a case of a 32-year-old woman who developed an antenatal Valsalva-induced retinal haemorrhage causing unilateral blindness 38 weeks into her pregnancy. Delivery was achieved by elective Caesarean section under epidural anaesthesia. The influence of anaesthetic technique on a recent retinal haemorrhage is discussed.- - - - - - - - - - ranking = 0.5keywords = anaesthesia (Clic here for more details about this article) |
