Sir,

We are grateful for the comments on our recent article. The correspondents claim that the conditions that we have treated would have lost vision in time due to their natural history, but we cannot entirely agree that this is the case with exception perhaps of diabetic retinopathy, which comprised only one patient in our study. We do, however, agree that any other modalities to control the intraocular pressure are also likely to have fared badly. The response of our unit to the poor results of diode laser trans-scleral cryophotocoagulation (TSCPC) has been to try to remove silicone in all cases, where possible, early in the management of the condition. Of course, a risk of retinal redetachment is then encountered.1 This risk we feel is justified given the high incidence of silicone oil-induced glaucoma2 and the poor results of control of the glaucoma thereafter emphasized from the results of our study. We are now using TSCPC only rarely when all other options have been ruled out.
