ObjectiveTo determine the effects of the intraocular injection of antivascular endothelial growth factor (anti-VEGF) drugs on the refractive status of infants with retinopathy of prematurity (ROP).DesignSystematic review and meta-analysis of the refractive status of infants with ROP who receive anti-VEGF drugs.Data sourcesThe PubMed, Web of Science and Embase databases and the ClinicalTrials.gov website were searched up to June 2020.Eligibility criteria when selecting studiesWe included randomised controlled trials (RCTs) and observational studies that compared refractive errors between anti-VEGF drug and laser therapies.Data extraction and synthesisData extraction and risk-of-bias assessments were conducted by two independent reviewers. We used a random-effect model to pool outcomes. The outcome measures were the spherical equivalents, axial length (AL), anterior chamber depth (ACD) and lens thickness (LT).ResultsThirteen studies involving 1850 eyes were assessed: 914 in the anti-VEGF drug group, and 936 in the control (laser) group. Children who received anti-VEGF drug treatment had less myopia than those who received laser therapy (mean difference=1.80 D, 95% CI 0.97 to 2.63, p<0.0001, I2=78%). The AL, ACD and LT did not reach statistical significance difference between the two groups. The current evidence indicates that the refractive safety in children with ROP is better for anti-VEGF drug treatment than for laser therapy.ConclusionsThis meta-analysis indicates that anti-VEGF drug therapy results in less myopia compared with laser therapy. However, there are relatively few published articles on refractive errors in ROP, and so high-quality and powerful RCTs are needed in the future.PROSPERO registration numberCRD42020160673.

Retinal vein occlusion (RVO) is one of the most prevalent causes of visual loss in the Western World. Its pathogenesis is still not completely known. Chronic macular edema and ischemia compromise the functional and anatomical status of the retina. Antivascular endothelial growth factor (anti-VEGF) injections have demonstrated better results than other previous options, including observation or laser therapy. This narrative review aims to analyze the current aspects related to these drugs.

Background/Aim. Retinopathy of prematurity (ROP) is a vasoproliferative retinopathy which affects the blood vessels of the retina during its development. The aim of this study was to evaluate the incidence and the degree of refractive errors in premature infants with severe ROP treated with antivascular endothelial growth factor (anti-VEGF) (bevacizumab). Methods. This prospective study included 21 patients (42 eyes) nine months old who received intravitreal injection of anti-VEGF therapy. The control group consisted of 45 patients (90 eyes) who were subjected to laser treatment. In cycloplegia each patient underwent retinoscopy, keratorefractometry, and A-scan ultrasonography. Results. Myopia was present in 47.62% of the eyes in the study group and in 33.33% of the eyes in the control group, but there were no statistically significant differences between these groups. Seven (16.67%) eyes in the study group and 17 (18.89%) eyes in the control group were discovered to have high myopia (SE? spherical equivalents < -3.0 D ? dioptre). Clinically significant hypermetropia was higher in the study group (47.62%) than in the control group (34.44%), but with no statistically significant difference. In addition, high hypermetropia was significantly greater in the control group (15.56%) than in the study group (11.90%) (p < 0.001). Astigmatism was more common in the control group than in the study group (81.11% vs 71.43%, respectively), especially high astigmatism (56% vs 43%, respectively). Also the more common form of astigmatism was with the rule (WTR) both in the study and the control group (42.86% vs 55.56%, respectively). Anisometropia was significantly greater in the control group (24.44%) than in the study group (9.52%) (p < 0.05). The children from the study group had significantly greater lens thickness, and a shorter anterior chamber depth than children from the control group (p < 0.01). There was no significant difference in the axial length of the eye between the groups. Conclusion. At the 9-month follow-up myopia was present in the patients with severe ROP treated with anti-VEGF, but high myopia was present to a lesser degree than in the laser treated patients. This difference is possibly related to anterior segment development. Research into the longer-term refractive outcomes is necessary with observation of the biometric components, visual acuity, and the visual field in order to monitor the real effects of this therapy.

Background/aimsTo evaluate the efficacy of antivascular endothelial growth factor (anti-VEGF) agents pretreatment before vitrectomy for patients with complicated proliferative diabetic retinopathy (PDR).MethodsThe PubMed, Embase and the Cochrane Central Register of Controlled Trials were searched up to June 2017 to identify related studies. The Peferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines were followed. The StataSE V.12.0 software was used to analyse the relevant data. The weighted mean difference, relative risk and their 95% CIs were used to assess the strength of the association.Results14 randomised controlled trials involving 613 patients were assessed, the anti-VEGF pretreatment group included 289 patients and the control group included 324 patients. Our analysis indicated that anti-VEGF pretreatment before vitrectomy for complicated PDR could facilitate much easier surgery regarding less intraoperative bleeding, less endodiathermy, shorter duration of surgery, less iatrogenic retinal breaks, less frequency of using silicone oil and relaxing retinotomy (P<0.05). Additionally, anti-VEGF pretreatment could also achieve better postoperative best-corrected visual acuity, less early recurrent vitreous haemorrhage (VH) and quicker absorption of recurrent VH (P<0.05). However, the incidence of late recurrent VH, recurrent retinal detachment or related secondary surgery could not be reduced (P>0.05).ConclusionThe pretreatment of anti-VEGF agents before vitrectomy for patients with complicated PDR might facilitate much easier surgery and better visual rehabilitation, reduce the rate of early recurrent VH and accelerate its absorption. Moreover, future better-designed studies with larger sample sizes are required to further evaluate the efficacy of different anti-VEGF agents and reach a firmer conclusion.

Context: Hypertension events are the dominant adverse events observed in patients receiving the antivascular endothelial growth factor (anti-VEGF) monoclonal antibodies bevacizumab and ramucirumab treatment, which severe hypertension, particularly hypertensive emergencies, may cause acute target organ injury and major cardiovascular events, that has limited the administration of anti-VEGF monoclonal antibodies. The current meta-analysis aimed to examine the relative risk (RR) of hypertension associated with anti-VEGF monoclonal antibodies. Evidence Acquisition: PubMed, EMBASE, ASCO Abstracts, ESMO Abstracts, Cochrane Library, and Clinical Trials.gov were searched until July 2019 for relevant phase II and III randomized controlled trials (RCTs). Statistical analyses were performed to examine the RR (with 95% confidence intervals (CIs)) of hypertension associated with the anti-VEGF monoclonal antibodies. Results: Ninety four RCTs and 51088 patients were included in the current meta-analysis. According to the results, compared with the control arms, anti-VEGF monoclonal antibodies increased the risk of all-grade (RR: 3.45, 95% CI: 2.98 - 4.00) and high-grade (RR: 5.63, 95% CI: 5.05 - 6.26) hypertension. In the subgroup analyses, the risk of high-grade hypertension varied significantly with cancer type, so that the highest RR was for patients with ovarian cancer (17.27, 95% CI: 8.50 - 35.08), whereas the risk of all-grade hypertension did not vary significantly. When stratified based on drug types and drug dose, no significant difference was discovered. Conclusions: Anti-VEGF monoclonal antibodies significantly increased the risk of hypertension. The risk may vary with tumor type. Clinicians should be aware of the adverse reaction and clinical monitoring as well as effective management of such situations, particularly for high-risk patients.

Zusammenfassung Hintergrund Durch Verbesserungen in der neonatologischen Versorgung von Frühgeborenen und die Entwicklung neuer Behandlungsmöglichkeiten der Frühgeborenenretinopathie („retinopathy of prematurity“ [ROP]) haben sich die Anforderungen an das ROP-Screening seit der Veröffentlichung der letzten Fassung der deutschen Leitlinie zum ROP-Screening im Jahr 2008 verändert. Auf Grundlage aktueller Studiendaten wurde die Leitlinie in 2020 grundlegend überarbeitet und in einer aktualisierten Fassung veröffentlicht. Ziel Dieser Artikel fasst die wichtigsten Änderungen in der neuen Leitlinie zusammen. Ergebnisse Die Altersgrenze für einen Screeningeinschluss wurde für Kinder ohne zusätzliche Risikofaktoren auf ein Gestationsalter von unter 31 Wochen gesenkt. Die Mindestdauer für eine Sauerstoffsupplementation, die einen Einschluss in das Screening bei Frühgeborenen erforderlich macht, wurde auf über 5 Tage angehoben. Eine Behandlung bei ROP in Zone II kann nun schon bei jedem Stadium 3 mit Plus-Symptomatik unabhängig von der Anzahl der betroffenen Uhrzeiten erfolgen. Für die Nachkontrollen nach Anti-VEGF („vascular endothelial growth factor“)-Therapie wurden Kriterien zur Frequenz und Dauer definiert. Das verbindliche Dokument für diese und weitere neue Empfehlungen ist die Leitlinie selber. Schlussfolgerungen Die Empfehlungen der Leitlinie ermöglichen eine zuverlässige Identifikation von Kindern mit ROP-Risiko für den Einschluss in das Screening und eine rechtzeitige Erkennung fortgeschrittener Krankheitsstadien für die Therapieeinleitung, um so Erblindung durch ROP zu verhindern.

Intravitreal antivascular endothelial growth factor (VEGF) agents are widely used to treat ocular conditions but the benefits and harms of these treatments are uncertain. We conducted a systematic review to compare the effects of aflibercept, bevacizumab and ranibizumab on best-corrected visual acuity (BCVA) changes, quality of life and ocular or systemic adverse events in patients with neovascular age-related macular degeneration (NVAMD), diabetic macular oedema (DME) and central or branch retinal vein occlusion (RVO). We searched published and unpublished literature sources to February 2017 for randomised controlled trials and cohort or modelling studies reporting comparative costs in the USA. Two reviewers extracted data and graded the strength of the evidence using established methods. Of 17 included trials, none reported a clinically important difference (≥ 5 letters) in visual acuity gains between agents. Nine trials provide high-strength evidence of no difference between bevacizumab and ranibizumab for NVAMD. Three trials provide moderate-strength evidence of no difference between bevacizumab and ranibizumab for DME. There was low-strength evidence of similar effects between aflibercept and ranibizumab for NVAMD, aflibercept and bevacizumab for RVO and all three agents for DME. There was insufficient evidence to compare bevacizumab and ranibizumab for RVO. Rates of ocular adverse events were low, and systemic harms were generally similar between groups, although 1 DME trial reported more arterial thrombotic events with ranibizumab versus aflibercept. Overall, no agent had a clear advantage over another for effectiveness or safety. Aflibercept and ranibizumab were significantly less cost-effective than repackaged bevacizumab in two trials. Systematic review registration number: CRD42016034076.
