Massive vitreous retraction.
More than half of previously hopeless cases of MVR can be anatomically reattached by tight elastic equatorial compression with a circling silicone sponge. Visual results range from light perception to 20/30, with most retinas being so severely damaged by the MVR that they regain 20/200 or less vision. Because of the possible serious complications of this operation, it is indicated only for otherwise incurable cases of retinal detachment. In properly selected patients, the benefit of limited vision may clearly justify this admittedly difficult and unpleasant procedure.
