BACKGROUND: Retro- or peribulbar anaesthesia are the standard procedures for cyclodestructive surgery. Because these methods of anaesthesia may further compromise optic nerve function, especially in advanced @entity726 , subconjunctival anaesthesia was evaluated as an alternative procedure in cyclocryotherapy. @entity1 AND METHODS: 1. To evaluate the current methods of anaesthesia a questionnaire was sent to all University Eye Clinics in Germany in 2001. 2. A prospective, consecutive study concerning cyclocryotherapy in advanced @entity726 was started using subconjunctival anaesthesia with 5 % @entity2072 or, alternatively, 2 % @entity10541 in 25 eyes of 25 @entity1 in each group. @entity158 during cyclocryotherapy was recorded using a 10-point rating-scale (1 = no @entity158 to 10 = intolerably severe @entity158 ) and adverse events were also recorded. RESULTS: 1. 88.6 % of the University Eye Clinics in Germany replied to our questionnaire. In 2001 cyclocryotherapy was performed in 80.6 % of the University Eye Clinics in Germany (T  bingen not included), 16.1 % among them solely used cyclocryotherapy for the treatment of advanced @entity726 . 2. Using 5 % @entity2072 for subconjunctival anaesthesia - 92 % of @entity1 experienced no @entity158 and 8 % of @entity1 reported very mild @entity158 during cyclocryotherapy. One @entity1 reported @entity390 , 4 @entity1 mouth dryness. After anaesthesia with @entity10541 - 80 % experienced no @entity158 , 12 % very mild @entity158 , and 8 % mild @entity158 . There were no systemic side effects. CONCLUSION: Most of the @entity1 experienced no @entity158 during cyclocryotherapy using subconjunctival anaesthesia with @entity2072 or @entity10541 . Therefore, risks and side effects of retro- or parabulbar anaesthesia can be successfully avoided by this simple modification.
