    Abstract:
    Secondary glaucoma is a relatively common complication after pars plana vitrectomy and silicone oil injection for repair of complex retinal detachment. The aim of this study was to evaluate the influence of silicone oil tamponade on intraocular pressure elevation and to identify the mechanism of this elevation. The study included 45 eyes of 45 patients who had undergone pars plana vitrectomy and silicone oil tamponade for repair of complex retinal detachment. Ophthalmic examination was performed before vitrectomy, and one and six months after vitrectomy. The increase in intraocular pressure was measured one month postoperatively in 37.77% of patients. The mechanism of intraocular pressure increase was silicone oil emulsification in 52.98%, closure of Ando's iridectomy in 23.54%, and idiopathic angle closure glaucoma in 23.54% of patients with elevated intraocular pressure. After silicone oil removal, elevated intraocular pressure persisted in 7 (15.55%) patients; in 5 patients it was controlled medically, while two patients underwent glaucoma surgery. Six months postoperatively 3 patients developed secondary neovascular glaucoma due to the prolipherative ischemic disease. Elevation of intraocular pressure following vitrectomy with silicone oil tamponade had a temporary effect, as it did not lead to permament intraocular pressure elevation but regressed after silicone oil removal from the eye.
