OBJECTIVE: To compare the efficacy and complications of using 1000-centistoke versus 5000-centistoke silicone oil for complex @entity1713 repair. STUDY DESIGN: Case series. PLACE AND DURATION OF STUDY: LRBTTertiary Eye Hospital, Karachi, from January 2007 to June 2013. METHODOLOGY: Eighty-five eyes (85 @entity1 ) presenting with superior rhegmatogenous @entity1713 associated with PVR grades B and C (involving not more than 3 clock hours) were randomized to either 1000 centistokes (n=44) or 5000 centistokes (n=41) silicone oil group. All @entity1 underwent 23-gauge pars plana vitrectomy surgery with silicone oil intraocular tamponade. @entity1 data was analysed at 18 months post-operatively. IBM SPSS 21 was used for data analysis. RESULTS: There were 52 male and 33 female @entity1 aged between 22 and 70 years (45.2 _plusmn;16.2). After the first surgery, successful reattachment of the retina was achieved in 67 eyes (78.8%); of which 35 eyes were in 1000-centistoke and 32 eyes in 5000-centistoke groups. Mean pre-operative Best Corrected Visual Acuity (BCVA) was 1.63 _plusmn;0.54 which was improved to a mean post-operative BCVAof 1.46 _plusmn;0.78 (1.42 _plusmn;0.74 in 1000-centistoke group; 1.49 _plusmn;0.78 in 5000 centistoke group). The 1000-centistoke group had a significantly higher frequency of oil emulsification which necessitated early removal of silicone oil. There were 66 eyes (77%) with at least one complication (34 eyes in 1000-centistoke group; 32 eyes in 5000-centistoke group) including @entity231 , @entity2687 , raised IOP, @entity8814 , @entity548 and @entity2479 . CONCLUSION: Although visual and anatomical outcomes were comparable between the two groups, the 1000-centistoke silicone oil group developed early oil emulsification necessitating its early removal.
