Background: It has been long believed that most eyes that undergo silicon oil (SO) infusion during vitreo–retinal surgery are likely to be inflicted with glaucoma. However, with better qualities of silicon oil and better surgical techniques, does silicon oil use in retina surgery induce glaucoma? Methods: A retrospective chart review of 36 eyes of 34 patients with silicon oil infusion was conducted. Demographic data including past ocular history, eye drops, intra–ocular pressure measurements (IOP) and visual acuity were recorded for the pre–operative visit and all subsequent post–operative visits. We compared pre–operative IOP to IOP recorded at approximately 1 month follow–up visit and then at at least 3 month follow–up visit. Results:The average IOP increase from the pre–op to the post–op visit at approximately 1 month was 4.1 mmHg (n=36). 12 of 36 eyes required glaucoma drops during the first month for IOP control. The average IOP increase from pre–op to post–op visit at approximately 3+ months was 1.7 mmHg (n=20); and only 6 of these eyes required glaucoma drops. 25 of 36 eyes had the SO removed. In these 25 eyes, SO remained in place for an average of 112 days; mean IOP increase from pre–op to last follow–up visit was 3.15 mmHg. No eyes in the entire study required glaucoma surgery or removal of SO for increases in IOP. Conclusions: At 3+ months post–op, IOP is only slightly increased in all eyes that have a silicon oil infusion. A small number of patients do require medical therapy temporarily to control the IOP; however, the risk of developing silicon oil induced glaucoma is relatively low.
