The Evaluation of Silicon Oil Evacuation Procedure In Cipto Mangunkusumo Hospital Indonesia

Abstract

Background: Injection of Silicon oil (SO) is a standard procedure for vitreous replacement in vitrectomy procedure for retinal detachment cases. It acts as a great tamponading agent for reattachment of retinal breaks or retinal detachment. Despite its minor side effect, SO could cause several complications such as cataract, endothelial decompensation, increased intraocular pressure, and secondary glaucoma. Thus needed to be evacuated after the retinal reattachment is stabilized. Following the evacuation procedure, visual acuity is known to be significantly improved. However, some cases show decreased of visual acuity due to retinal redetachment, optic nerve damage due to secondary glaucoma, hypotony, vitreous hemorrhage, expulsive hemorrhage, and cornea abnormality. Methods: A retrospective descriptive study of retinal detachment patients underwent SO evacuation procedure in Cipto Mangunkusumo Hospital,Results: There were seventy-seven cases of retinal detachment undergoes SO evacuation within the period of September 2017-January 2018. There was an improvement of visual acuity (greater than 6/60) after one month of SO evacuation. Anatomical retinal reattachment was successfully observed in 91% patient. The most occurring complication after SO evacuation includes secondary glaucoma and retinal redetachment.Conclusion: SO evacuation is a standard procedure following a vitrectomy in retinal detachment cases. The evacuation procedure yields in positive benefit for patient in term of visual acuity and anatomical structure.

“…A meta-analysis study byHe, et al (2018) states that the condition of PVR before vitrectomy surgery and OS implantation is not a risk of redetached, but the formation of PVR after evacuation of SO can be the main cause of redetached retina. This is in line with this study which found the condition of redetached retina, but indeed the researchers did not assess the degree of PVR in this study 5,17. CONCLUSIONThe research subjects in this study had an age with a median of 51 years with the majority of subjects being in the age range of 46-65 years, female and living in Bali with the majority of phakic and pseudophakic lens status.…”

“…Second, the mechanical impact of the balanced salt solution (BSS) during the SO evacuation action can divide the SO droplet into smaller droplets, which are more likely to obstruct the trabecular meshwork. 5,12,13,14 The indications for evacuation of SO may vary in each case. In this study, for the most indications, retina reattached > 3 months was 73.9%, while…”
