In recent years buckling procedures for the correction of retinal detachment have achieved a large measure of acceptance and success. However, drainage of subretinal fluid has often been a perplexing and complicated process, sometimes fraught with great hazards.1 These include choroidal hemorrhage, formation of new retinal holes, incarceration of retina and vitreous into the drainage site, and the development of massive retinal folds.
It is desirable, therefore, to be able to achieve the beneficial effects of a "buckle" without drainage of subretinal fluid. In suitable cases this frequently can be achieved through the utilization of a Custodis polyviol implant.2,3 However, a considerable volume of polyviol implant is essential. Often, when it is sewn into place, marked elevations in intraocular pressure result. Corneal edema and temporary closure of the central retinal artery are the unwanted results. It is then essential to perform repeated paracenteses or to wait a rather
