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.
继发性青光眼是玻璃体切除联合硅油注入修复复杂性视网膜脱离术后较为常见的并发症。本研究旨在评估硅油填充对眼压升高的影响，并确定眼压升高的机制。该研究纳入了45例接受玻璃体切除联合硅油填充修复复杂性视网膜脱离的患者的45只眼。在玻璃体切除术前、术后1个月和6个月进行眼科检查。37.77%的患者在术后1个月测量到眼压升高。眼压升高的机制在52.98%的患者中是硅油乳化，23.54%是安藤虹膜切除术闭合，23.54%是特发性闭角型青光眼。硅油取出后，7例（15.55%）患者眼压持续升高；5例患者通过药物控制，2例患者接受了青光眼手术。术后6个月，3例患者因增生性缺血性疾病发生继发性新生血管性青光眼。玻璃体切除联合硅油填充术后眼压升高具有暂时性，因为它不会导致永久性眼压升高，而是在硅油从眼内取出后消退。
