Intravitreal conbercept injection with panretinal photocoagulation for high-risk proliferative diabetic retinopathy with vitreous hemorrhage

AIM:To assess the clinical efficacy and safety of combining panretinal photocoagulation(PRP)with intravitreal conbercept(IVC)injections for patients with high-risk proliferative diabetic retinopathy(HR-PDR)complicated by mild or moderate vitreous hemorrhage(VH),with or without diabetic macular edema(DME).METHODS:Patients diagnosed with VH with/without DME secondary to HR-PDR and received PRP combined with IVC injections were recruited in this retrospective study.Upon establishing the patient’s diagnosis,an initial IVC was performed,followed by prompt administration of PRP.In cases who significant bleeding persisted and impeded the laser operation,IVC was sustained before supplementing with PRP.Following the completion of PRP,patients were meticulously monitored for a minimum of six months.Laser therapy and IVC injections were judiciously adjusted based on fundus fluorescein angiography(FFA)results.Therapeutic effect and the incidence of adverse events were observed.RESULTS:Out of 42 patients(74 eyes),29 were male and 13 were female,with a mean age of 59.17±12.74y(33-84y).The diabetic history was between 1wk and 26y,and the interval between the onset of visual symptoms and diagnosis of HR-PDR was 1wk-1y.The affected eye received 2.59±1.87(1-10)IVC injections and underwent 5.5±1.02(4-8)sessions of PRP.Of these,68 eyes received PRP following 1 IVC injection,5 eyes after 2 IVC injections,and 1 eye after 3 IVC injections.Complete absorption of VH was observed in all 74 eyes 5-50wk after initial treatment,with resolution of DME in 51 eyes 3-48wk after initial treatment.A newly developed epiretinal membrane was noted in one eye.Visual acuity significantly improved in 25 eyes.No complications such as glaucoma,retinal detachment,or endophthalmitis were reported.CONCLUSION:The study suggests that the combination of PRP with IVC injections is an effective and safe modality for treating diabetic VH in patients with HR-PDR.

Efficacy comparison of multipoint and single point scanning panretinal laser photocoagulation in non-proliferative diabetic retinopathy treatment

BACKGROUND Non-proliferative diabetic retinopathy(NPDR)poses a significant challenge in diabetes management due to its microvascular changes in the retina.Laser photocoagulation,a conventional therapy,aims to mitigate the risk of progressing to proliferative diabetic retinopathy(PDR).AIM To compare the efficacy and safety of multi-spot vs single-spot scanning panretinal laser photocoagulation in NPDR patients.METHODS Forty-nine NPDR patients(86 eyes)treated between September 2020 and July 2022 were included.They were randomly allocated into single-spot(n=23,40 eyes)and multi-spot(n=26,46 eyes)groups.Treatment outcomes,including bestcorrected visual acuity(BCVA),central macular thickness(CMT),and mean threshold sensitivity,were assessed at predetermined intervals over 12 months.Adverse reactions were also recorded.RESULTS Energy levels did not significantly differ between groups(P>0.05),but the multi-spot group exhibited lower energy density(P<0.05).BCVA and CMT improvements were noted in the multi-spot group at one-month posttreatment(P<0.05).Adverse reaction incidence was similar between groups(P>0.05).CONCLUSION While energy intensity and safety were comparable between modalities,multi-spot scanning demonstrated lower energy density and showed superior short-term improvements in BCVA and CMT for NPDR patients,with reduced laser-induced damage.

Efficacy and safety of intravitreal ranibizumab with panretinal photocoagulation followed by trabeculectomy compared with Ahmed glaucoma valve implantation in neovascular glaucoma

AIM：To evaluate the efficacy and safety of intravitreal ranibizumab（IVR）with panretinal photocoagulation（PRP）followed by trabeculectomy compared with Ahmed glaucoma valve（AGV）implantation in neovascular glaucoma（NVG）.METHODS：This was a retrospective comparative study.We reviewed the cases of a total of 45 eyes from 45 NVG patients among which 23 eyes underwent AGV implantation and the other 22 underwent trabeculectomy. The causes of neovascular glaucoma included：diabetic retinopathy（25 eyes）,and retinal vein occlusion（20 eyes）.All patients received preoperative IVR combined with postoperative PRP. The mean best-corrected visual acuities（BCVA）were converted to the logarithms of the minimum angle of resolution（log MAR）for the statisitical analyses.Intraocular pressure（IOP）,the log MAR BCVA and surgical complications were evaluated before and after surgery.The follow-up period was 12 mo.RESULTS：A total of 39 cases showed complete regression of iris neovascularization at 7d after injection,and 6 cases showed a small amount of residual iris neovascularization. The success rates were 81.8% and 82.6% at 12 mo after trabeculectomy and AGV implantation,respectively. In the trabeculectomy group,the log MAR BCVA improved at the last follow-up in 14 eyes,remained stable in 6 eyes and decreased in 2 eyes. In 4 cases,slight hyphemas developed after trabeculectomy. A shallow anterior chamber developed in 2 cases and 2 vitreous hemorrhages. In the AGV group,the log MAR BCVA improved in 14 eyes,remained stable in 5 eyes and decreased in 4 eyes. Slight hyphemas developed in 3 cases,and a shallow anterior chamber in 3 cases. The mean postoperative IOP was significantly lower in both groups after surgery（F=545.468,P〈0.05）,and the mean postoperative log MAR BCVA was also significantly improved（F=10.964,P〈0.05）with no significant difference between two groups.CONCLUSION：It is safe and effective to treat NVG with this combined procedure,and we found similar results after IVR＋AGV implantation＋PRP and IVR＋trabeculectomy＋PRP in eyes with NVG.

Effects of intravitreal conbercept before panretinal photocoagulation on lipid exudates in diabetic macular documented by optical coherence tomography

AIM: To evaluate the effects of intravitreal conbercept(IVC) as adjunctive treatments before panretinal photocoagulation(PRP) to decrease hyperreflective dots(HRDs) in Chinese proliferative diabetic retinopathy(PDR) patients. METHODS: Fifty-nine enrolled patients were categorized into 2 groups: single dose IVC(0.5 mg/0.05 m L) 1 wk before PRP(Plus group) or PRP only(PRP group). Six months later, we measured the best corrected visual acuity(BCVA), central macula thickness(CMT) by optical coherence tomography and counted the number of HRDs in different retina layers. RESULTS: The average CMT significantly decreased in Plus group but increased in PRP group. The average BCVA in the Plus group was also significantly better than that in the PRP group. Total HRDs decreased in the Plus group but increased in PRP group significantly. IVC pre-treatment has beneficial effects on reducing HRDs forming in the inner retina layer while the PRP alone increased the HRDs in the outer retina layer. CONCLUSION: IVC is a promising adjunctive treatment to PRP in the treatment of PDR. Single dose IVC one week before PRP is suggested to improve retina blood-retina barrier, decrease lipid exudate and inhibit HRDs development in PDR.

Efficacy of intravitreal conbercept combined with panretinal photocoagulation for severe nonproliferative diabetic retinopathy without macular edema

AIM: To assess efficacy of intravitreal conbercept(IVC) injection in combination with panretinal photocoagulation(PRP) vs PRP alone in patients with severe nonproliferative diabetic retinopathy(SNPDR) without macular edema(ME).METHODS: Forty-eight patients with SNPDR without ME(56 eyes) were divided into the PRP group and IVC+PRP group(the pulse group) in this retrospective clinical study. Conbercept was intravitreally administered to patients in the pulse group 1 wk before treatment with PRP and followed up for 1, 3, and 6 mo. The best-corrected visual acuity(BCVA, log MAR), center foveal thickness(CFT), visual acuity(VA) improvement, and adverse reactions were compared between groups.RESULTS: In the PRP group, the BCVA reduced at 1 and 3 mo before improving at 6 mo. In the pulse group, baseline BCVA decreased continuously at 1 mo, increased at 3 and 6 mo. BCVA in the pulse group was better than that in the PRP group at 1, 3, and 6 mo. There was an increase in CFT in the PRP group during follow-up compared with baseline. In the pulse group, CFT was increased at 1 mo relative to baseline, steadily decreased to the baseline level at 3 and 6 mo. There was a more significant reduction in CFT in the pulse group during follow-up compared with the PRP group. The effective rates of VA in the PRP and the pulse groups were 81.48% and 100%, respectively. CONCLUSION: As PRP pretreatment, a single dose of IVC administration has beneficial effects for preventing PRPinduced foveal thickening and increasing VA in patients with SNPDR without ME.

Simultaneous pars plana vitrectomy,panretinal photocoagulation,cryotherapy,and Ahmed valve implantation for neovascular glaucoma

AIM:To describe and evaluate the efficacy of Ahmed glaucoma valve implantation(AGV)combined with pars plana vitrectomy(PPV)in a single surgical act for the treatment of advanced neovascular glaucoma(NVG).METHODS:Retrospective observational case series included 51 eyes from 50 patients with severe NVG treated with PPV,AGV,and panretinal photocoagulation and/or cryotherapy in a single surgical act during a 13-year period(2005-2018).Preoperative,intraoperative and postoperative data at day 1 and months 1,3,6,21,and 24 were systematically collected.Definition of surgical success was stablished at IOP between 6 and 21 mm Hg with or without topical treatment.RESULTS:Main indications for surgery were NVG secondary to proliferative diabetic retinopathy(39.2%)and central retinal vein occlusion(37.3%).Mean(±SD)preoperative IOP was 42.0±11.2 mm Hg decreasing to 15.5±7.1 mm Hg at 12 mo and 15.8±9.1 mm Hg at 24 mo of follow up.Cumulative incidence of success of IOP control was 76.0%at first postoperative month,reaching 88.3%at 6 mo.Prevalence of successful IOP control at long term was 74.4%at 12 mo and 71.4%at 24 mo.Eye evisceration for unsuccessful NVG management was required in 1 case(2.0%).CONCLUSION:Combination of AGV implantation and PPV in a single act may be a suitable option for severe forms of NVG in a case-by-case basis for effective IOP control and a complete panretinal photocoagulation.

全视网膜光凝治疗糖尿病视网膜病变对视野影响的研究进展

糖尿病视网膜病变(DR)早期视野改变往往比视力更能及时反映病情进展。而全视网膜光凝(PRP)治疗DR在延缓病情进展的同时也造成了患眼视力下降和视野缩小等副作用。有研究表明,PRP治疗后的DR患者可因中心20°范围内的视野缺损而导致驾驶测试失败。为保证PRP疗效同时达到降低并发症的目的,激光技术不断改进与发展,通过调整激光参数、使用新型激光系统、与抗血管内皮生长因子(VEGF)药物联合、中西医结合治疗等方式可一定程度改善患眼视野,实现更佳疗效。未来可考虑在缺血指数(ISI)量化分析下,对视网膜缺血程度进行分级,依据ISI指标和视网膜无灌注区分布探索PRP治疗建议的最佳阈值及光凝范围,从而为DR患者提供更及时、更合理的个性化治疗方案。文章就PRP治疗DR对视野的影响进行简要综述。

目的:探讨玻璃体腔内注射康柏西普(IVC)联合全视网膜光凝(PRP)治疗合并黄斑水肿(DME)的重度非增殖性糖尿病性视网膜病变(SNPDR)患者的给药时机。方法:前瞻性病例对照研究。选取2017-05/2018-10于我院确诊的合并DME的SNPDR患者85例85眼,随机分为三组:对照组29眼仅予以PRP治疗;IVC组28眼在IVC后1wk予以PRP;PRP组28眼在PRP后1wk予以IVC。随访12mo,观察治疗前及治疗后1、3、6、12mo最佳矫正视力(BCVA)、黄斑区中心凹厚度(CMT)变化,记录IVC频次。结果:三组患者治疗后的BCVA较治疗前改善,CMT较治疗前降低(P<0.05)。治疗后IVC组和PRP组BCVA优于对照组,CMT低于对照组(P<0.05)。治疗后3mo,ICV组BCVA(0.24±0.18,LogMAR)下降均较PRP组(0.38±0.29,LogMAR)明显(P<0.05)。治疗后1、3mo,ICV组CMT(313.89±61.69、287.64±43.94μm)下降均较PRP组(347.50±56.55、318.04±49.33μm)明显(P<0.05)。IVC给药频次为IVC组3.07±1.33次、PRP组3.93±1.60次(P<0.05)。结论:治疗合并DME的SNPDR患者,IVC联合PRP治疗优于单纯PRP治疗,且在PRP治疗之前予以抗VEGF药物,短期内BCVA提高、黄斑水肿减轻,长期观察可减少IVC次数,降低感染风险,减轻经济负担。
