Patient Characteristics And Outcome After Silicone Oil Removal At Cicendo Eye Hospital, April 2011 - March 2012

Objective: To observe the patient characteristics and complications after silicone oil removal, in vitrectomized patients with SO as an internal tamponade. Method: This study was designed for observational-descriptive of medical records vitrectomized patients with SO tamponade and subsequent removal in April 2011 to March 2012. Cases were classified into 2 groups between different viscosities (SO 1300 cSt and 5500 cSt). Furthermore, each group was then evaluated by anatomic improvement (attachment or redetachment) and complication rates after SO removal (cataract formation, glaucoma, SO emulsification). Result: The indications for the use of silicone oil were rhegmatogenous retinal detachment in 47 eyes (85.5%), 4 eyes (7.3%) were associated with proliferative vitreoretinopathy (PVR), 4 eyes (7.3%) had vitreous hemorrhage caused by AMD (1 eye) and 3 eyes had proliferative diabetic retinopathy with tractional retinal detachment. Silicone oil removal was done on average 118.87 days for SO 5500 cSt (range from 28 until 360 days) and average 116.25 days for SO 1300 cSt (range from 81 days until 185 days). After silicone oil removal, the retina remains attached in 50 (90.09%) of the eyes, 34% had visual acuity > 6/120 and 7.27 % had Intra Ocular Pressure (IOP) > 21 mmHg. Comparing 1000 cSt and 5000 cSt silicone oil-filled eyes, redetachment occurred more frequently in the latter group especially in cases with associated PVR. Conclusion: Rates of anatomical success from this study was 90.09%, but redetachment was found in 9.09% eyes. Several complications were found after SO removal such as cataract formation, glaucoma and SO emulsification.
