Abstract:
AIM: To investigate the clinical efficacy of gonioscopy-assisted transluminal trabeculotomy(GATT)for secondary high intraocular pressure after vitrectomy.METHODS: A retrospective study was conducted on 10 patients(15 eyes)with secondary high intraocular pressure(IOP)after vitrectomy treated with GATT in Department of Ophthalmology, Chengdu First People's Hospital from January 2019 to May 2022. The best-corrected visual acuity(BCVA), IOP, number of IOP-lowering drugs, and complications before operation and at 1d, 1wk, 1, 3 and 6mo after operation were recorded, and the surgical success rate was analyzed.RESULTS:There was no difference in BCVA before and 6mo after operation(Z=0, P=1). The mean IOP decreased from 28.33±9.48mmHg to 17.47±3.78(1d), 18.8±3.29(1wk), 19.13±3.62(1mo), 20.31±3.66(3mo)and 18.03±3.23mmHg(6mo; all P<0.05). The average medication used before surgery was 2(2, 4), and the average medication used 6mo after surgery was 1(0, 2), which was significantly decreased(P<0.001). The total success rate of surgery at 1d, 1wk, 1, 3 and 6mo after surgery was 87%(13 eyes), 93%(14 eyes), 87%(13 eyes), 73%(11 eyes)and 93%(14 eyes)respectively. The main postoperative complications were transient hyphema(10 eyes, 67%)and transient elevated IOP(5 eyes, 33%). No complications seriously affecting the vision occurred.CONCLUSION: GATT is safe and effective in the treatment of secondary high intraocular pressure after vitrectomy.
