Usefulness of different silicone oils for intraocular tamponade

PURPOSE: This paper presents the influence of different silicone oils on surgical results achieved after pars plana vitrectomy and silicone oil tamponade. MATERIAL AND METHODS: Pars plana vitrectomy and silicone oil tamponade were used for the treatment of 141 eyes with proliferative Vitreoretinopathy, diabetic retinopathy and posttraumatic retinal detachment. In group I (23 eyes), group II (26 eyes), group III (32 eyes) and group IV (60 eyes) following silicone oils were used, respectively: highly purified silicone oil with viscosity 5000 mPa(x)s, 1000 mPa(x)s, cosmetically purified silicone oil with viscosity 3690 mPa(x)s and 1000 mPa(x)s. RESULTS: The achieved results did not show any statistically significant differences according to anatomical and functional results and early and late postoperative complications between the analysed groups. Compared to other groups, highly purified silicone oil with viscosity 5000 mPa(x)s did not show any emulsification. CONCLUSIONS: The achieved results show that different silicone oils can be successfully used for intraocular tamponade. Highly purified silicone oil with viscosity 5000 mPa(x)s is most biocompatible.
