| 1 | Prognosis value of Chinese Ocular Fundus Diseases Society classification for proliferative diabetic retinopathy on postoperative visual acuity after pars plana vitrectomy in type 2 diabetes显示文摘AIM: To compare the postoperative visual acuity among eyes with proliferative diabetic retinopathy(PDR) of different stages after pars plana vitrectomy(PPV) in type 2 diabetic patients. METHODS: A retrospective study was conducted for PDR eyes undergoing PPV in type 2 diabetic patients. All patients were divided into three groups based on Chinese Ocular Fundus Diseases Society(COFDS) classification for PDR: Group A(primary vitreous hemorrhage), Group B(primary fibrovascular proliferation) and Group C(primary vitreous hemorrhage and/or fibrovascular proliferative combined with retinal detachment). The postoperative visual acuity and the change between postoperative and preoperative visual acuity were compared among three groups. The associated risk factors for postoperative visual acuity were analyzed in the univariate and multiple linear aggression. RESULTS: In total, 195 eyes of 195 patients were collected in this study, including 71 eyes of 71 patients in Group A, 75 eyes of 75 patients in Group B and 49 eyes of 49 patients in Group C. The eyes in Group A got better postoperative best-corrected visual acuity(BCVA) compared to the eyes in Group B and C(0.48±0.48 vs 0.89±0.63, P<0.001;0.48±0.48 vs 1.04±0.67, P<0.001;respectively). The eyes in Group A got more improvement of BCVA compared to the eyes in Group B and C(1.07±0.70 vs 0.73±0.68, P=0.004;1.07±0.70 vs 0.77±0.78, P=0.024;respectively). In the multiple linear regression analysis, primary fibro-proliferative type(β=0.194, 95%CI=0.060-0.447, P=0.01), retinal detachment type(β=0.244, 95%CI=0.132-0.579, P=0.02), baseline log MAR BCVA(β=0.192, 95%CI=0.068-0.345, P=0.004), silicone oil tamponade(β=0.272, 95%CI=0.173-0.528, P<0.001) was positively correlated with postoperative log MAR BCVA. Eyes undergoing phacovitrectomy had better postoperative BCVA(β=-0.144, 95%CI=-0.389 to-0.027, P=0.025). CONCLUSION: PDR eyes of primary vitreous hemorrhage type usually have better visual acuity prognosis compared to primary fibrovascular proliferation type and retinal detachment type. COFDS classification for PDR may have a high prognostic value for postoperative visual outcome and surgical management indications. | Tie-Zhu Lin Yan Kong Cheng Shi Emmanuel Eric Pazo Guang-Zheng Dai Xian-Wei Wu Ling Xu Li-Jun Shen | 2022 | International Journal of Ophthalmology(English edition)2022，15，10： | 1 |
| 2 | Investigating the impact of preoperative corneal astigmatism orientation on the postoperative spherical equivalent refraction following intraocular lens implantation显示文摘Background:To investigate the impact of the orientation of preoperative corneal astigmatism on achieving the postoperative target refraction following monofocal intraocular lens(IOL)implantation.Methods:This study enrolled 339 eyes who had uneventful cataract surgery or refractive lens exchange(RLE)with subsequent monofocal IOL implantation.Eyes were initially categorized dependent upon axial length and then on the orientation of preoperative anterior corneal astigmatism.Group 1 had against-the-rule(ATR)anterior corneal astigmatism,group 2 had with-the-rule(WTR)anterior corneal astigmatism,and group 3 had oblique(OB)anterior corneal astigmatism.The preoperative corneal astigmatism was determined by the IOLMaster(Carl Zeiss Meditec AG).Postoperative refraction was completed for all eyes,and the results were calculated and compared for the separate groups.Results:In eyes with axial lengths greater than 22.0 mm and less than 25.0 mm there was a significant difference between the magnitude of preoperative corneal astigmatism between groups 2 and 3 with 0.827±0.376 D in group 2,and 0.677±0.387 D in group 3.The mean postoperative spherical equivalent(SE)prediction error was−0.132±0.475 D in group 1,0.026±0.497 D in group 2,and−0.130±0.477 D in group 3.There was a significant difference between groups 1 and 2.There was no significant difference in the magnitude of preoperative corneal astigmatism and postoperative SE prediction error between the anterior corneal astigmatism orientation groups in eyes with axial lengths of less than or equal to 22.0 mm and greater than or equal to 25.0 mm.Conclusions:The orientation of preoperative anterior corneal astigmatism significantly affected the postoperative biometry prediction error in eyes with astigmatism of 1.75 D or less in eyes with the axial length between 22.0 mm and 25.0 mm.However,the results were not clinically significant. | Richard N.McNeely Salissou Moutari Eric Pazo Jonathan E.Moore | 2018 | Eye and Vision2018，5，1： | 0 |
| 3 | Persistent macular oedema following Best vitelliform macular dystrophy undergoing anti-VEGF treatment显示文摘Dear Editor,I am Dr. Tie-zhu Lin, from He Eye Specialist Hospital, Shenyang, China. I write to present the case of persistent macular oedema following Best vitelliform macular dystrophy(BVMD) undergoing anti-vascular endothelial growth factor(VEGF) treatment. BVMD also called Best’s disease, is a hereditary disease due to mutation in the BEST1 gene located on chromosome 11;and has vastly variable phenotypic expression. | Tie-Zhu Lin Emmanuel Eric Pazo Yue Ren Li-Jun Shen | 2022 | International Journal of Ophthalmology(English edition)2022，15，5： | 0 |
| 4 | Long-term efficacy and safety of YAG laser vitreolysis for vision degrading myodesopsia显示文摘AIM:To assess the long-term efficacy and safety of yttrium-aluminum garnet(YAG)laser vitreolysis for vision degrading myodesopsia(VDM)caused by posterior vitreous detachment(PVD).METHODS:This retrospective study reviewed VDM patients of PVD type undergoing YAG laser vitreolysis.The baseline demographic information,the patterns of floaters,the number of floaters,and the subjective improvement of floater sympotoms(ranging from 0 to 100%)from medical records were collected.Significant improvement was defined as a relief of floater symptoms of≥50%at the final visit.The long-term efficacy and safety of YAG laser vitreolysis were analyzed.The risk factors linked to significant improvement of floater symptoms were defined using univariate and multivariate logistic regression analyses.RESULTS:The final analysis included 221 patients with VDM.The mean age of patients was 61.08±7.74y,and the mean length of follow-up was 21.38±5.61mo.Totally 57.01%of patients experienced a significant improvement in their floater symptoms after YAG laser therapy,and none of them developed delayed retinal abnormalities such as retinal tears or detachments.Age(OR=1.049,95%CI=1.007-1.092,P=0.021)was identified as a significant risk factor for significant improvement in VDM.CONCLUSION:YAG laser vitreolysis is an effective and secure treatment for PVD-type VDM,and patients of advanced age are more likely to get favorable outcomes. | Tie-Zhu Lin Cheng Shi Xing Yang Emmanuel Eric Pazo Yan-Nian Hui Li-Jun Shen | 2023 | International Journal of Ophthalmology(English edition)2023，16，11： | 0 |
