![]() During follow-up period, logMAR best-corrected visual acuity (BCVA), intraocular pressure (IOP), slit-lamp biomicroscopy, indirect and slit-lamp ophthalmoscopy were registered.įunctional outcomes were divided into three categories. If there was cataract, a combined clear corneal incision phacoemulsification and intraocular lens (IOL) implantation was performed. Silicone oil was extracted between 6 weeks and 12 months after the initial procedure through a standard two-port pars plana surgery. The objective of the present study is to evaluate anatomical and functional outcomes after silicone oil removal in patients with retinal detachment and proliferative vitreoretinopathy in an eye care referral center in Joinville, SC, southern Brazil. Additionally, in spite of a permanent attached retina, some patients may have unexplained vision loss after silicone oil extraction. It is generally associated with residual vitreoretinal traction at the vitreous base some other factors may also contribute to unfavorable outcomes, like intra and postoperative inflammation, intraoperative bleeding, retinal pigment epithelium exposure, retinectomy and extended duration of the surgical procedure.Īs suggested by some authors, a prophylactic 360-degree laser retinopexy prior to silicone oil extraction may help to reduce retinal redetachment rates. Nevertheless, after silicone oil extraction, recurrence of PVR and consequently retinal redetachment can occur. To avoid long-term complications due to the presence of silicone oil inside the eye, such as cataract, glaucoma and ceratopathy, its removal is usually necessary. ![]() Proliferative vitreoretinopathy (PVR) is an important complication of rhegmatogenous retinal detachment and its treatment requires a long-acting endotamponade, such as silicone oil, to reduce the rate of recurrent retinal detachment. ![]() Benefits of silicone oil extraction and the associated risks of complications due to a new surgical procedure must be carefully evaluated before surgical indication. Prophylactic 360-degree laser retinopexy may have led to favorable outcomes. Most patients had good anatomical and visual outcomes after silicone oil extraction. Five patients with attached retina had unexplained optic disc atrophy. Twenty-three cases (43.4%) showed visual acuity improvement, whereas 11 cases (20.8%) were stable and 19 cases (35.8%) showed visual acuity worsening. ![]() Time of intraocular tamponade and association of phacoemulsification with silicone oil extraction were not considered as risk factors for retinal redetachment. Forty-eight eyes (90.5%) had attached retina at the last follow-up examination. Resultsįifty-three patients were followed up for a mean period of 1,262 days.įourteen eyes (26.4%) underwent cataract surgery combined with silicone oil extraction. Functional outcomes were divided into three categories (stability, worsening, or improvement) according to visual acuity variation before the surgery and at the last follow-up visit. Anatomical outcomes were related to the duration of silicone oil tamponade and the surgical procedure performed. Patients with cataract underwent a combined clear corneal phacoemulsification with intraocular lens implantation in the same procedure. Prophylactic 360-degree peripheral laser photocoagulation was performed one to three months before silicone oil extraction. Retrospective, noncomparative study of patients with retinal detachment and posterior proliferative vitreoretinopathy followed up after silicone oil removal. To evaluate anatomical and functional outcomes after silicone oil extraction in patients with retinal detachment and proliferative vitreoretinopathy in an eye care referral center in Joinville, SC, southern Brazil.
