This chapter definitively reviews the increasingly common ophthalmic procedures performed in the elderly. It discusses the important changes in ocular physiology that occur with age and anaesthesia, in particular those affecting intraocular pressure. It reviews the assessment prior to surgery and the choice of the anaesthetic technique. The indications for general anaesthesia are presented and the current views on inductions agents and airway protection are then discussed. The place of nitrous oxide in ophthalmic anaesthesia is then explored. The techniques for local anaesthesia are then reviewed including topical anaesthesia, local infiltration to orbital nerve blockade, with or without sedation. The current views on cannula or needle-based blockage are presented, and the skills and complications of each are discussed. The needs of specific procedures are then explored. These include surgery for cataract, glaucoma, vitreoretinal, squint, and eye trauma.
