Title

IRIS NEOVASCULARIZATION SECONDARY TO SILICONE OIL OXANE HD: A CASE REPORT

Introduction

Oxane HD is a high molecular weight silicone oil used to treat retinal ruptures. It can cause granulomatous uveitis and neovascular glaucoma in the postoperative period.

Methods

Case report and discussion corroborating the literature

Results

A 62 years old, caucasian, female patient was submited to a pars plana vitrectomy in 2010 due to a regmatogenic retinal detachment with the infusion of Oxane 5700 being removed 6 months later without complications . In 2019, the patient evolved with low visual acuity in the same eye that was diagnosticated with regmatogenic retinal redetachment. The patient was submitted to another pars plana vitrectomy with the infusion of Oxane HD due to the extension and location of the detachment. During the post-operative, patient evolved with local pain, intra ocular inflammation and iris neovascularization without retinal detachment, ischemia nor silicone oil in anterior chamber. Was performed the silicione oil removal because was prescribed ocular corticoid and ocular hypotensive without significant control in three months. There was regression of neovascularization, however with new retinal detachment, opting for the infusion of osi 5700 without complications until the present moment.

Discussion

The Oxane HD Bausch and Lomb is a combination of olefinas RMN-3 and silicone oil capable of prolonged occlusion of retinal ruptures due to its high viscosity, superficial tension and molecular weight in comparison with other type. Heavy tampons can cause uveitis and neovascular glaucoma due to toxicity, immune response, mechanic trauma and oil emulsification. Studies have demonstrated that some cases with uveitis only respond to the treatment after the silicone oil removal.
