1/2. Acute angle closure glaucoma precipitated by intranasal application of cocaine.We describe a patient who developed acute angle-closure glaucoma following the application of topical intranasal cocaine. A 46-year-old woman underwent an elective antral washout under general anaesthesia and with local application of 25 per cent cocaine paste to the nasal mucosa. Twenty-four hours post-operatively the patient developed sudden painful blindness which was found to be due to acute glaucoma. cocaine with its indirect sympathomimetic activity causes mydriasis, that can precipitate acute angle-closure glaucoma in predisposed individuals with a shallow anterior chamber. Although the incidence is rare, otolaryngologists need to be aware of this potential complication.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/2. Bilateral subacute angle-closure glaucoma in association with tonic pupils post-coronary artery bypass graft.Anterior and posterior visual pathway disturbances have been reported post-coronary artery bypass graft surgery. Acute angle-closure glaucoma after general anaesthesia has also been well described in the literature. To date, however, there are only two cases of angle closure caused by tonic pupils. The case is reported herein of bilateral subacute angle-closure glaucoma that occurred following coronary artery bypass graft surgery in association with tonic pupils.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
