目的:了解玻璃体视网膜手术后早期眼压变化的特点和规律性。方法:玻璃体视网膜手术患者100例,其中单纯巩膜扣带术23例,单纯玻璃体切割35例,玻璃体切割+硅油填充18例和玻璃体切割+C3F8气体填充24例,采用Goldmann压平眼压计测量术前和术后7d每天眼压。观察和分析各组手术后眼压的变化,如眼压升高>25mmHg,则局部或全身应用降眼压药物治疗。结果:首次眼压升高发生于术后24h内占86.5%,术后2d占8.1%,术后3d占5.4%。单纯巩膜扣带术、单纯玻璃体切割术后24h内眼压最高,平均眼压分别为21.04±7.49mmHg和20.43±7.79mmHg,高眼压发生率分别为5/23(21.7%),6/35(17.1%)。硅油填充组在术后1d,气体填充组在术后2d眼压最高,平均眼压分别为25.17±8.69mmHg和29.21±10.30mmHg,两组高眼压发生率分别为10/1(855.6%),16/2(466.7%)。结论:玻璃体视网膜手术后眼压升高多发生在早期,硅油或气体填充术后高眼压发生率较高,眼压升高幅度较大。
Objective: To understand the characteristics and regularity of early intraocular pressure changes after vitreoretinal surgery. Methods: Vitreoretinal surgery in 100 patients, including simple scleral buckling in 23 cases, simple vitrectomy in 35 cases, vitrectomy + silicone oil filled in 18 cases and vitrectomy + C3F8 gas filled in 24 cases, the use of Goldmann tonometry Tonometer IOP before and after 7 days. Observation and analysis of changes in intraocular pressure after surgery, such as intraocular pressure increased> 25mmHg, local or systemic application of intraocular pressure medication. Results: The first intraocular pressure (IOP) occurred in 86.5% within 24 h after operation, 8.1% after 2 days and 5.4% after 3 days. The intraocular pressure (IOP) was the highest within 24 h after simple scleral buckling and simple vitrectomy. The mean intraocular pressure (IOP) was 21.04 ± 7.49 mmHg and 20.43 ± 7.79 mmHg respectively. The incidences of ocular hypertension were 5/23 (21.7%) and 6/35 (17.1%). At 1 day after operation, the intraocular pressure (IOP) in the silicone oil-filled group was the highest at 2 days after operation, with the mean IOPs of 25.17 ± 8.69mmHg and 29.21 ± 10.30mmHg, respectively. The incidences of ocular hypertension were 10/1 (855.6% , 16/2 (466.7%). CONCLUSION: Intraocular pressure (IOP) elevation occurred after vitreoretinal surgery mostly in the early stage. Occurrence of intraocular hypertension after silicone oil or gas filling operation was higher, and IOP increased more.
