We devised a method for safely placing mattress sutures for radial scleral buckling of posterior retinal holes. The ability to pass the needle in the anteroposterior direction, as well as the ability to tie the posterior ends of the mattress suture anteriorly where they are easily accessible, makes this method of placing the mattress suture safe and effective for posterior radial buckles.

The aetiology of retinal dialysis has traditionally been closely linked to blunt trauma to the eye, and experimental work in the past has tended to confirm this view. However, a close look at eyes that have suffered known concussional injury indicates that trauma is rarely associated with retinal dialysis. The aetiology of dialysis is discussed and a technique for treatment is proposed.
The fundamental problem of massive retinal retraction in the contractual stage is due to the establishment of contracting membranes, both on the surface of the retina and away from the surface. These membranes distort and immobilize the retina in a way that cannot be effectively treated by buckling alone. The injection of liquid silicone enables the membrane to be stretched to a point at which it either ruptures spontaneously, or can be ruptured at a point of weakness by a needle tip. The retina, being still elastic, is able to stretch further than the membrane. At this point the membrane is actively elevated by the injecting needle and separated from the retina aa widely as possible. Liquid silicone enables significant membranes to be easily visualized, when separated, to be divided.
Giant equatorial tears are frequently affected by massive vitreous retraction and the signs of this are easy to see. Liquid silicone is indicated at the stage of immobilization of giant tears complicated by massive vitreous retraction, and the use of this material is justified, for its properties allow the solution of the difficult problems presented by these tears; lastly, there is no evidence that liquid silicone is in any way harmful to the human retina.
1 Massive vitreous retraction must be diagnosed according to a well-defined set of criteria. 2 Massive vitreous retraction is treatable, despite Machemer's assertion this morning, in its contracting as well as immobile stages, but surgery must be carried out as soon as possible after the diagnosis is made. 3 Liquid silicone is the correct treatment and is not toxic to the human eye.
