Midazolam and flumazenil in ophthalmology. 1990

Department of Anaesthesiology, Rothschild Foundation, Paris, France.

Midazolam's pharmacodynamic properties are used in ophthalmology in several indications: 1. to relieve anxiety and unwanted reactions during radial keratotomy in ambulatory patients; 2. to provide sedation and amnesia during cataract surgery using local anaesthesia, in combination with low doses of phenoperidine; 3. to induce general anaesthesia, combined with fentanyl and vecuronium, for intraocular surgery in the elderly; and 4. to decrease intraocular pressure. Flumazenil is not in routine use but is usually administered to antagonise the deleterious effects of midazolam on upper airway resistances and the respiration system and may be used to reverse "paradoxical", i.e. anxiogenic reactions to benzodiazepines in the elderly.

D007429	Intraocular Pressure	The pressure of the fluids in the eye.	Ocular Tension,Intraocular Pressures,Ocular Tensions,Pressure, Intraocular,Pressures, Intraocular,Tension, Ocular,Tensions, Ocular

D008568	Memory	Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.
D008874	Midazolam	A short-acting hypnotic-sedative drug with anxiolytic and amnestic properties. It is used in dentistry, cardiac surgery, endoscopic procedures, as preanesthetic medication, and as an adjunct to local anesthesia. The short duration and cardiorespiratory stability makes it useful in poor-risk, elderly, and cardiac patients. It is water-soluble at pH less than 4 and lipid-soluble at physiological pH.

D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses.

D005442	Flumazenil	A potent benzodiazepine receptor antagonist. Since it reverses the sedative and other actions of benzodiazepines, it has been suggested as an antidote to benzodiazepine overdoses.	Flumazepil,Anexate,Lanexat,Ro 15-1788,Romazicon,Ro 15 1788,Ro 151788
