Role of silicone oil in retinal reattachment

Aim: to study the role of liquid silicone to be used in the procedure to elevate membranes from the detached retina methods: complicated retinal detachment is one in which vitreous cannot be as internal temponade. this occurs due to the formation of pvr membranes cause massive vitreo retinal retraction. the fundamental problem of massive retinal retraction in the contractual stage is due to formation of contracting membranes. these membranes form both on the surface of the retina,away from the retina and the sub retinal space. these membranes distort and immobilized the retina in such a way that it cannot be treated by buckling alone. results: the injection of liquid silicone enables the membrane to be stretched to appoint at which these either rupture spontaneously or can be ruptured at weak point by a needle tip. retina being tremendously elastic tissue is able to stretch further than the membrane. at this point membrane is actively elevated by the injecting needle and separated from the retina as widely as possible. patients selected for this study were those who presented with complicated retinal detachment in outpatient department of ophthalmology,bv hospital bahawalpur. the technique was different for both the groups. in group-a,we were able to completely reattach the retina in ten cases (62.5%) and partially in four cases (25%). retina could not be reattached in two cases (12.5%).in group b there was no pvd. out of fourteen cases,we achieved completely reattachment in seven cases (50%) and partial reattachment in 5 (35%). in 2 cases (15%) retina remained detached. © 2016,lahore medical and dental college. all rights reserved.
