Abstract
The aims of this retrospective study were to determine the outcome of retinal detachment repair using the drainage, air injection, cryotherapy and explant surgical sequence (‘CD-ACE’ technique) for bullous retinal detachments and also to identify the complications attributable to the injection of the gas. The D-ACE technique was used to repair 206 detachments over a ten year period of which 138 (67%) were successfully re-attached with a single operation. The sub-group of these patients (n = 66) with bullous retinal detachments who would be considered suitable for repair using the technique of pneumoretinopexy (PR) showed a single operation success rate of 85% after D-ACE. Complications attributable to the gas injection occurred in 18 eyes (8.5%). In only four of these (1.9%) did retinal surgery ultimately fail as a result of complications caused by injection of the gas, which represents 10% of all the failures. The results of this series show that the serious complication rate from injecting air into the vitreous cavity is low and that the success rate for treating relatively uncomplicated bullous retinal detachments using the D-ACE technique compares favourably with the results of other published series using either the D-ACE procedure or pneumoretinopexy.
