To study the incidence and risk factors of raised intraocular pressures (IOPs) in the follow-up of transconjunctival sutureless vitrectomy (TSV).
A retrospective observational study was performed on 635 patients who underwent TSV under a single surgeon. The IOPs were recorded using a calibrated non-contact tonometer at seven postoperative visits, viz., day 1, 7 and 1, 3, 6 months, and 1 day and 1 month following silicone oil removal.
IOP rise was seen in 24.25% (154) out of the 635 eyes studied. Among patients under 50 years of age, 37.73% had an IOP rise, compared to 21.55% above 50 years (Odds Ratio 2.206). Among males, 30.32% had an IOP rise, as compared to 15.98% females (OR 2.287). In eyes with retinal detachment, 49.16% had raised IOP (OR 5.435), and 24.05% with proliferative diabetic retinopathy (OR 1.780), as opposed to 15.38% with macular hole and 12.32% with epiretinal membrane. This was statistically significant (P < 0.001). In eyes with silicone oil, 34.9% developed a rise in IOP (OR 2.738) as compared to 11.94% of other surgeries (OR 0.697). This was statistically significant (P < 0.001).
We observed an increase in IOP postoperatively, more in those under 50 years, males and patients undergoing surgery for RD and PDR.
研究经结膜无缝合玻璃体切除术（TSV）随访中眼压升高（IOP）的发生率和危险因素。
对 635 例单眼接受 TSV 的患者进行回顾性观察性研究。术后 7 次随访使用校准的非接触眼压计记录眼压，分别为术后第 1、7 天和第 1、3、6 个月，以及硅油取出后第 1 天和 1 个月。
在 635 只眼中，有 24.25%（154 只）出现眼压升高。在 50 岁以下的患者中，有 37.73%出现眼压升高，而 50 岁以上的患者中只有 21.55%（优势比 2.206）。在男性中，有 30.32%出现眼压升高，而女性中只有 15.98%（比值比 2.287）。在视网膜脱离的眼中，49.16%的眼压升高（比值比 5.435），而在增殖性糖尿病视网膜病变的眼中，有 24.05%（比值比 1.780），而在黄斑裂孔的眼中，有 15.38%，在视网膜前膜的眼中，有 12.32%。这具有统计学意义（P <0.001）。在硅油眼，有 34.9%的眼压升高（比值比 2.738），而其他手术中只有 11.94%（比值比 0.697）。这具有统计学意义（P <0.001）。
我们观察到术后眼压升高，在 50 岁以下、男性和接受 RD 和 PDR 手术的患者中更为常见。
