To determine sequential intraocular pressure (IOP) changes after pars plana vitrectomy (PPV) with or without combined phacoemulsification and intraocular lens implantation (PE & IOL).
Consecutive patients who underwent PPV with PE & IOL (combined group) or without PE & IOL (vitrectomy group) were reviewed for postoperative sequential IOPs and the number of IOP lowering medications used. Of the 68 patients (68 eyes) who underwent simple PPV, 41 eyes were allocated to the vitrectomy group, and 27 eyes to the combined group.
The mean IOPs were higher on postoperative days one and two, as compared to preoperative values, in both groups. The mean IOP changes on postoperative day one (10.0 mmHg vs. 5.3 mmHg, p = 0.02) and day two (3.7 mmHg vs. 1.3 mmHg, p = 0.02) were significantly higher in the combined group.
Phacovitrectomy is associated with a higher risk of IOP elevation during the early postoperative period than PPV alone. Caution should be exercised in patients who are vulnerable to IOP fluctuations when combined surgery is indicated.
确定行或不行联合超声乳化白内障吸除及人工晶状体植入术(PE&IOL)的玻璃体切割术(PPV)后眼压(IOP)的连续变化情况。
回顾性分析连续接受联合PE&IOL的PPV(联合组)或未接受PE&IOL的PPV(玻璃体切割术组)的患者术后的连续眼压及使用的降眼压药物数量。在68例行单纯PPV的患者(68只眼)中,41只眼被分配至玻璃体切割术组,27只眼被分配至联合组。
两组术后第1天和第2天的平均眼压均高于术前值。联合组术后第1天(10.0 mmHg对5.3 mmHg,p = 0.02)和第2天(3.7 mmHg对1.3 mmHg,p = 0.02)的平均眼压变化显著更高。
与单纯PPV相比,超声乳化玻璃体切割术在术后早期眼压升高的风险更高。对于有眼压波动风险的患者,如需行联合手术应谨慎。
