Silicone Oil Induced Glaucoma: Risk Factors and Management Results

Abstract

Purpose: Our aim was to describe the risk factors of silicone oil induced glaucoma (SOIG), to discuss the challenges encountered during management as well as its results. Material and Methods: Retrospective study including 120 eyes operated by 23 gauges pars plana vitrectomy with silicone oil (SO) tamponade. All patients had a complete pre- and post-operative assessment. SOIG was defined as a postoperative intra ocular pressure (IOP) greater than 21mmHg for at least 6 weeks. Patients who developed intra ocular hypertension (IOHT) underwent SO removal and were put on medical, laser or surgical treatment if OHT persisted. We studied the risk factors SOIG onset as and IOP control rates with each therapeutical means. Results: SOIG was noted in 45 patients (37,5%). The risk factors found in the univariate study were diabetes (p=0,007), rhegmatogenous retinal detachment (p=0,036), SO presence in the anterior chamber (AC) (p
