[Ultrastructure of the retina in flunitrazepam anesthesia]

Ultrastructure of the retina under experimental flunitrazepam anaesthesia of 1 hour duration was studied. Alterations of neurons and glial cells were not revealed neither after cessation of anaesthesia, nor following 24 or 48 hours after it. These findings seem to indicate that flunitrazepam has no effect on the metabolism of the retina, thus its application in the ophtalmology is free of side effects.
