AIM:To investigate the rates of emulsification in silicone oil(SO)tamponades of differing viscosities used during pars plana vitrectomy(PPV)in the treatment of complicated vitreoretinal diseases.METHODS:This study was a prospective randomized clinical trial.Totally 290 cases with greater likelihoods of secondary detachment were included and randomly grouped into either Siluron 2000(n=143)or Siluron 5000(n=147)SO tamponades with 23-gauge PPV.Patient followups and data analyses were conducted 1,3,6,and 12 mo post-surgery.RESULTS:The time of the SO emulsification ranged from 1 to 17 mo,with a mean of 7.3±4.2 mo.The Siluron 5000 group showed a slower emulsification rate in comparison to the Siluron 2000 group.The Siluron 2000 group took a shorter time to show signs of emulsification,necessitating earlier SO removal.However,there were no significant differences in the occurrence of complications,including secondary retinal detachment,cataract,corneal abnormality,high intraocular pressure and hypotony.CONCLUSION:The Siluron 2000 SO tamponade shows a faster rate of emulsification than the Siluron 5000 SO,necessitating earlier removal.Both groups show similar results in terms of anatomical success and visual acuity outcome,and there is no significant difference between the SOs regarding the occurrence of complications. 相似文献

Purpose
To report on 2 cases of aggressive posterior retinopathy of prematurity (ROP) treated with intravitreal ranibizumab (Lucentis®) and laser photocoagulation.Methods
Two premature females, born at 25 and 26 weeks’ gestation with a birth weight of 530 and 550 g, respectively, with aggressive posterior ROP received combined treatment with laser photocoagulation and intravitreal ranibizumab (0.3 mg [30 µl]) to each eye. Structural outcomes were evaluated by indirect ophthalmoscopy and documented by retinography.Results
An intravitreal injection was made at 34 weeks of postmenstrual age in the first case, followed by laser photocoagulation 1 week later. There was a partial regression of ROP with treatment. Five weeks later, neovascularization regrowth with bleeding in both eyes (intraretinal and subhyaloid) occurred and retreatment with combined therapy was performed. In the second case, single therapy with laser photocoagulation was made at 34 weeks of postmenstrual age. In spite of the confluent photocoagulation in the avascular area, progression to 4A ROP stage occurred 1 week later. Both eyes were retreated 1 week later with intravitreal ranibizumab and laser photocoagulation. Treatment resulted in ROP regression in both cases. There were no signs of systemic or ocular adverse side effects.Conclusion
The cases presented show that combination therapy of indirect laser photocoagulation and intravitreal ranibizumab can be effective in the management of aggressive posterior ROP. Further investigation on anti-VEGF safety in premature infants is necessary. Additional studies are needed to define the role of anti-VEGF in ROP treatment.Key Words: Retinopathy of prematurity, Laser photocoagulation, Ranibizumab, Anti-VEGF therapy 相似文献6.

Mandatory screening performed by an experience ophthalmologist remains the most important pillar in the management of retinopathy of prematurity (ROP). The current gold standard for treatment of proliferative ROP is still panretinal laser photocoagulation, depending on severity, in combination with vitreoretinal surgery if necessary. The first case series of off-label intravitreal anti-VEGF treatment are encouraging. In addition to intravitreal anti-VEGF therapy, other treatment concepts such as supplementation with IGF-1 or omega-3 fatty acids also represent interesting pharmacological approaches to the management of ROP. However, larger controlled trials are required to validate the benefits and safety of these systemic treatment approaches. 相似文献

ObjectiveTo determine the incidence of retinopathy of prematurity and severity of disease at a large Canadian tertiary care centre, as well as to determine risk factors for disease and current treatment practices.MethodsThis was a retrospective cohort study of infants admitted to the neonatal intensive care unit (NICU) at McMaster Children’s Hospital, who underwent screening for retinopathy of prematurity between August 2010 and August 2016.ResultsThe overall incidence of retinopathy of prematurity was 67.1% (418/623 infants); severe retinopathy of prematurity was seen in 14.3% (89/623). This signified an increase compared to our previous study at the same institution, where the incidence of retinopathy of prematurity was 40.4% and severe retinopathy of prematurity was 9.2% between 2006 and 2010. Stage 1 disease showed the greatest increase, from 9.0% (38/423) to 21.0% (131/623). Our cohort had a higher proportion of infants born at 24 weeks GA or less (15.7% vs 8.7%). Predictors of retinopathy of prematurity in a multivariate regression model were gestational age (OR = 0.829, p = 0.002), birth weight (OR = 0.712, p = 0.003) and length of NICU stay (OR = 0.844, p = 0.00). Treatment was performed in 10.5% (44/418) of infants with retinopathy of prematurity, with infants earlier in the study period mainly receiving laser photocoagulation and infants born in more recent years receiving intravitreal bevacizumab.ConclusionsThere has been an increase in retinopathy of prematurity incidence, both in early (stage 1) disease and in severe retinopathy of prematurity. This is partially explained by the almost doubling of the proportion of infants born at 24 weeks gestational age or less. Since mid-2013, intravitreal anti-VEGF therapy has replaced laser photocoagulation as the preferred treatment modality.This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors. 相似文献

AIM: To investigate common polymorphisms in VEGF, ACE, TNF and GST genes with retinopathy of prematurity (ROP) risk among Chinese infants.
METHODS: Nine polymorphisms in the above genes were genotyped on 724 advanced cases of ROP and 878 prematurely-born infants of low birth weight who were without any ophthalmologic disease. The frequencies of the polymorphisms were compared between cases and controls to identify the association present, if any.
RESULTS: Of the nine polymorphisms, only two showed significant associations: ACE insertion deletion (ID) polymorphism (P=0.031) and TNF -308G/A polymorphism (P<0.001). The former was associated with a reduced ROP risk [ID genotype, adjusted OR (aOR): 0.603, 95%CI: 0.427-0.893, P=0.034; DD genotype, aOR: 0.468, 95%CI: 0.229-0.626, P=0.002], while the latter showed an increased risk (GA genotype, aOR: 1.956, 95%CI: 1.396-2.465, P<0.001; AA genotype, aOR: 2.809, 95%CI: 1.802-4.484, P<0.001). The association was also noted at the allele level (ACE D allele aOR: 0.698, 95%CI: 0.294-0.883, P<0.001; TNF -308A allele aOR: 1.776, 95%CI: 1.446-2.561, P<0.001).
CONCLUSION: The ACE ID polymorphism can protect against ROP development while the TNF -308G/A can increase the risk of the disease among Chinese infants. 相似文献

Over the past decade there has been a paradigm shift in the treatment of retinopathy of prematurity (ROP) with the introduction of antivascular endothelial growth factor (anti-VEGF) treatments. Anti-VEGF agents have the advantages of being easier to administer, requiring less anesthesia, having the potential for improved peripheral vision, and producing less refractive error than laser treatment. On the other hand, it is known that intravitreal administration of anti-VEGF agents lowers VEGF levels in the blood and raises the theoretical concern of intraocular anti-VEGF causing deleterious effects in other organ systems, including the brain. As a result, there has been increased attention recently on neurodevelopmental outcomes in infants treated with anti-VEGF agents. These studies should be put into context with what is known about systemic comorbidities, socioeconomic influences, and the effects of extreme prematurity itself on neurodevelopmental outcomes. We summarize what is known about neurodevelopmental outcomes in extremely preterm infants with ROP, discuss the implications for determining the neurodevelopmental status using neurodevelopmental testing as well as other indicators, and review the existing literature relating to neurodevelopmental outcomes in babies treated for ROP. 相似文献

AIM: To evaluate the efficacy of intravitreal injection of conbercept (IVC) and ranibizumab (IVR) in patients with diabetic macular edema.
METHODS: Reviewers have searched 12 databases, including PubMed, Medline, EMBASE, Web of Science, Springer, ScienceDirect, OVID, Cochrane Library, ClinicalTrials.gov, cqVIP, WanFangdata and China National Knowledge Infrastructure (CNKI), up to December 28, 2018. RevMan 5.3 (Cochrane Library Software, Oxford, UK) was employed for statistical analysis. Fixed and random effects models were applied to assess heterogeneity. Odds ratio (OR) was applied for dichotomous variables; weighted mean difference (WMD) was applied for continuous variables. The confidence interval (CI) was set at 95%. Central macular thickness (CMT) and best-corrected visual acuity (BCVA) were employed to analyze the improvement of DME patients. Inclusion criteria for picking out studies were retrospective studies and randomized controlled trials (RCTs) that compared IVC and IVR for the treatment of diabetic macular edema.
RESULTS: Four retrospective studies and five RCTs were included with a total of 609 patients. No statistically significant difference was observed in mean CMT and mean BCVA in the baseline parameters [BCVA (WMD: -0.48; 95%CI: -1.06 to 0.10; P=0.1), CMT (WMD: -0.83; 95%CI: -15.15 to 13.49; P=0.91). No significant difference was found in the improvement of BCVA and adverse event (AE) in IVC group, compared with IVR group after treatment of loading dosage [the 1st month BCVA (WMD: 0.01; 95%CI: -0.26 to 0.27; P=0.96), the 3rd month BCVA (WMD: -0.04; 95%CI: -0.14 to 0.06; P=0.46); the 6th month BCVA (WMD: -0.24; 95%CI: -1.62 to 1.14; P=0.73)], AE (OR: 0.84; 95%CI: 0.38 to 1.84; P=0.66)]. A slight difference was found in the effectiveness rate (OR: 1.70; 95%CI: 0.97 to 2.96; P=0.06), There were statistically significant differences between IVC and IVR treatment in terms of CMT [1st month CMT (WMD: -19.88; 95%CI: -27.94 to -11.82; P<0.001), 3rd month CMT (WMD: -23.31; 95%CI: -43.30 to -3.33; P=0.02), 6th month CMT (WMD: -74.74; 95%CI: -106.22 to -43.26; P<0.001)].
CONCLUSION: Pooled evidence suggests that both IVC and IVR are effective in the therapy of diabetic macular edema and affirms that IVC presents superiority over IVR therapy in regard of CMT in patients with diabetic macular edema, but no statistically significant difference with regard to visual improvement. Relevant RCTs with longer-term follow-up are necessary to back up our conclusion. 相似文献

Purpose:To report the results of the survey for the role of anti-VEGF in the management of retinopathy of prematurity (ROP) among the members of Indian ROP (iROP) society.Methods:A questionnaire was designed in English using Google forms and its link was circulated to the members of the iROP society on their mobile numbers. The survey included questions pertaining to demographics, anti-VEGF agents, injection technique, post-injection follow-up, and documentation pertaining to their ROP practice. Anonymous responses were obtained and analyzed for individual questions.Results:226 members of the society were contacted and 157 responded (69.4%) to the survey. 137 (87.2%) respondents used anti-VEGF in the management of ROP. Aggressive posterior ROP (APROP) was the most common indication (78, 52.7%). The procedure was carried out in the main operation room (102, 70.3%) simultaneously for both the eyes (97; 68%) under topical anesthesia (134; 86.4%) by most of the respondents. One-hundred thirteen (77.9%) respondents used half of the adult dose, irrespective of the agent used; however, more than half of them preferred bevacizumab (85, 54%). 53 (36.3%) respondents followed up infants as per disease severity rather than a fixed schedule while only 33 (23%) performed photo documentation. 151 (96.2%) respondents felt the need for guidelines regarding the usage of anti-VEGF in ROP.Conclusion:There is an increase in the trend towards the use of anti-VEGF in the management of severe ROP, particularly APROP. However, there are considerable variations among the ROP practitioners regarding the agent, dosage, follow-up schedule, and documentation, suggesting the need for uniform guidelines. 相似文献

AIM:To investigate the clinical manifestations,diagnostic approaches,treatments,and outcomes of intraocular lymphoma.METHODS:In this retrospective study,16 patients(28 eyes)with intraocular lymphoma were recruited in the Department of Ophthalmology,Peking Union Medical College Hospital,from 2004 to 2019.All patients underwent comprehensive ophthalmic examinations.Vitreous specimens of 13 patients were sent for cytopathology examination and other adjunctive diagnostic procedures.Three patients were diagnosed with intraocular lymphoma according to analysis of the histopathological results of systemic lymphoma by one clinician.Twenty-three eyes were treated with intravitreal administration of methotrexate,4 eyes could not receive ocular treatment due to life-threatening lymphoma,and 1 eye did not require ocular treatment because the fundus lesions regressed after systematic chemotherapy.RESULTS:In 28 eyes,25 eyes were diagnosed with vitreoretinal lymphoma,and 3 eyes were diagnosed with ciliary body lymphoma,all of which were non-Hodgkin diffuse large B cell lymphomas.The final visual acuity improved in 15 eyes(54%),remained unchanged in 5 eyes(18%),and decreased in 8 eyes(29%).Anterior segment inflammation disappeared or reduced in 8 and 5 eyes,respectively;and 15 eyes had no anterior segment reaction.Twenty eyes had mild vitreous opacity,1 eye had mild vitritis,and 7 eyes had pars plana vitrectomy combinedwith silicone oil tamponade.Fundus lesions disappeared in 9 eyes and were relieved in 5 eyes;4 eyes showed no changes,and the remaining 10 eyes’fundus were normal.CONCLUSION:The clinical manifestations of intraocular lymphoma are diverse,and the misdiagnosis rate is high.Cytopathological analysis of vitreous is one of the gold standards for the diagnosis.Immunohistochemistry,gene rearrangement and flow cytometric immunophenotypic analysis can improve the diagnostic rate.Ocular chemotherapy or radiotherapy regimens may preserve visual acuity,and a multidisciplinary team can provide individualized treatment for the patients. 相似文献

早产儿视网膜病变(ROP)是发生于早产儿的一种未成熟视网膜血管增殖性眼病,是一种严重的儿童致盲性眼病。视网膜激光光凝术是治疗ROP的经典方法,然而激光治疗是破坏性的,尤其是在ROP Ⅰ区病变的情况下,视网膜激光光凝治疗会引起严重的并发症。研究表明,血管内皮细胞生长因子(VEGF)在ROP发生及发展过程中具有关键作用,而玻璃体腔注射抗VEGF药物不仅能有效控制ROP,并且为视网膜继续发育争取了机会。本文就玻璃体腔内注射抗VEGF药物治疗ROP的治疗指征、药物筛选、注射部位、给药剂量、疗效观察以及并发症对其进行综述。 相似文献

AIM: To assess the effect of intravitreal ranibizumab injection for retinopathy of prematurity (ROP) in Zone II Stage 3+.
METHODS: Data was collected from ROP patients with Zone II Stage 3+ who had intravitreal ranibizumab injections between October 2014 and January 2017 at the department of Ophthalmology in our hospital. No prior laser or other intravitreal therapy was done. Fundus examination was performed prior to the intervention and at each follow-up visit. Gestational age at birth, birth weight, sex, ROP zone, ROP stage, post menstrual age (PMA) at treatment, and follow-up period were recorded. The final clinical status of the retina was noted for each patient. The primary outcome measures included ROP recurrences requiring re-treatment, complete or incomplete peripheral vascularization
RESULTS: Eighty-six eyes of 46 premature infants with Zone II Stage 3+ROP were enrolled in the study. The mean gestational age at birth was 28.18±1.67wk (range: 25 to 33wk) and the mean birth weight was 1070.57±226.85 g (range: 720.00 to 1650.00 g). The mean PMA at treatment was 38.32±2.99wk (range: 32.29 to 46.00wk). Seventy-one eyes (82.56%) were treated successfully with intravitreal ranibizumab as monotherapy. Fifteen eyes (17.44%) developed recurrent disease. The mean interval between the treatment and retreatment was 5.96±3.22wk (range: 1.86 to 11.71wk). All eyes vascularized into zone III at the end of the study and among them 62 eyes (72.1%) achieved complete vascularization.
CONCLUSION: Intravitreal ranibizumab injection is an effective treatment in patients with zone II stage 3+ ROP. More patients with longer follow-up duration are mandatory to confirm the safety and efficacy of this treatment. 相似文献
