[Application of silicone oil in management of complicated retinal detachment surgery]

60 eyes of 60 cases with complicated retinal detachment were treated by vitrectomy combined with silicone oil tamponade, including grade D of proliferative vitreoretinopathy (PVR) in 27, giant retinal tears with posterior flaps folded up in 15, posterior polar or macular holes in 13 and traumatic PVR in 5 eyes. After 3-24 months of follow-up, it is shown that 48 eyes obtained anatomic reattachment, the success rate being 80%, and the post-operative visual acuities improved in 43 eyes of which 32 eyes achieved > 0.05. The authors consider that vitrectomy and membrane peeling create a situation for silicone oil tamponade to play its role fully, vitrectomy is perfected by the combination of silicone oil tamponade and the rate of success of the retinal detachment operation is increased. The theory, indications, advantages and disadvantages of silicone oil tamponade were briefly discussed.
