Abstract:
:Transmembrane electrical measurements were performed on the isolated rabbit iris-ciliary body (I-CB) to study the direct effects of halogenated inhalation anesthetic agents on the ciliary epithelium. Addition of either halothane, enflurane, or isoflurane to the control 95% O2:5% CO2 gas mixture resulted in a dose-dependent decrease in the short-circuit current (SCC) and potential difference (PD). This response was reversible after the anesthetic gas was discontinued. Pretreatment with either alpha-adrenergic or beta-adrenergic antagonists (phentolamine or timolol) had no effect on the halothane-induced decrease in SCC. Delivery of the analgestic gas N2O did not alter baseline electrical measurements across the isolated I-CB.
