Abstract
A series of 200 consecutive retinal detachments was examined prospectively to consider the physical sign of mobility of the detached retina. Retinal mobility was found to be absent in 28 cases, and this immobility is caused by periretinal membrane formation. The importance of retinal mobility when considering the case for non-drainage retinal surgery has been examined with particular emphasis on the tear/buckle relationship at the end of the operation. It was found that there was an excellent prognosis (92% success rate) for cases in which the retina was found to be mobile in the vicinity of the retinal tear, and a high proportion of these cases (71%) can be successfully treated with a non-drainage operation.
