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.
ABSTRACT
AIM: To observe the safety and efficacy of stab incision glaucoma surgery(SIGS)in the treatment of adult glaucoma.METHODS: A series of retrospective case studies were carried out from June 2018 to November 2020, the clinical data of 55 cases with 70 eyes of glaucoma treated with SIGS in our hospital were collected. Following up at 6mo after operation, the intraocular pressure(IOP), bleb and postoperative complications were observed.RESULTS: Among the included patients, 30 eyes were performed SIGS alonely, 40 eyes were performed SIGS combined with phacoemulsification. Among them, the operation of 33 eyes(47%)was completely successful, the operation of 28 eyes(40%)was partially successful, and the operation of 9 eyes(13%)were failed. The mean preoperative IOP under medication was 31.82±13.16mmHg, and at 1wk, 1, 3 and 6mo after operation, the mean IOP(14.97±5.25, 17.94±5.24, 18.43±4.74, 17.37±3.36)mmHg were all significantly lower than before operation, and the number of IOP-lowering drugs used at 6mo after operation [0(0, 1)] was significantly lower than before operation [3(2, 3)](P<0.001). At 6mo after operation, the filtering blebs' shape of the patients: 30 eyes(43%)of type I(functional bleb), 31 eyes(44%)of type Ⅱ(functional bleb), 7 eyes(10%)of type Ⅲ(flat bleb)and 2 eyes(3%)of type IV(encapsulated vesicular bleb)were included. During the follow-up period, 2 eyes had hyphema in anterior chamber, 4 eyes had inflammatory reaction in anterior chamber, 3 eyes had low IOP, shallow anterior chamber and excessive filtration, 1 eye had malignant glaucoma, 1 eye had endophthalmitis, 1 eye had choroidal detachment, 1 eye had choroidal detachment, and 9 eyes had scarring of filtering blebs.CONCLUSION: SIGS is effective in the treatment of primary open angle glaucoma, primary angle-closure glaucoma and some secondary glaucoma without serious complications.
ABSTRACT
· AIM:To investigate the influence of monovision design of cataract surgery on the prognosis visual quality in cataract patients.· METHODS:Totally 84 cases cataract patients (168 eyes) who receiving cataract surgery were enrolled from February 2016 to February 2017 in our hospital to conduct a prospective study.According to the different near addition in the monovision design,patients were divided into low near addition group (1.25D-1.75D) and high near addition group (2.25D-2.75D),each group was 42 cases.At postoperative 6mo,the binocular uncorrected near visual acuity,uncorrected intermediate visual acuity,uncorrected distance visual acuity and stereoscopic vision were compared between two groups.The visual function survival quality score before and after treatment were compared.· RESULTS:The binocular uncorrected intermediate and distance visual acuity in the low near addition group respectively was 0.27 ± 0.20,0.09 ± 0.08,and that in the high near addition group respectively was 0.29 ± 0.25,0.10±0.07,which had no statistically significant difference between two groups (P＞0.05).The binocular uncorrected near visual acuity in the high near addition group was 0.03±0.06,which was significantly better than the low near addition group 0.07 ± 0.04,the difference was statistically significant (P＜ 0.05).Before the treatment,the visual function-14(VF-14) score in each two group respectively was 27.93± 4.52,28.24 ± 4.91;after the treatment,VF-14 score in each two group respectively was 82.04±14.31,81.22±13.70,which had no statistically significant difference between two groups (P＞0.05).After treatment,the VF-14 score both significantly increased in the two groups (P＜0.05).The proportion of patients with the normal stereoscopic vision,peripheral stereovision and macular stereovision in the low near addition group respectively was 47.6％,31.0％,21.4％;and that in the high near addition group respectively was 42.9％,23.8％,33.3％,which had no statistically significant difference between two groups (P＞0.05).· CONCLUSION:Two kinds of near addition have similar advantages to cataract patients after cataract surgery on uncorrected visual acuity,the quality of visual function and stereopsis.
