Purpose: To report a case of choroidal neovascularisation and leakage in a myopic female predicted to be a choroideraemia carrier treated with intravitreal anti-vascular endothelial growth factor (anti-VEGF). Methods: Case report. Results: A female magazine editor presented with sudden decrease in vision in her right eye, with Snellen visual acuities (VAs) of 1/60 and 3/60 in the right and left eyes respectively. She was diagnosed with choroidal neovascularisation (CNV) formation and subretinal haemorrhage in her right eye. This is on a background of previous presentations, the first of which was 20 years ago for declining left eye vision. She was subsequently found to be a predicted choroideraemia carrier. However, she also has high myopia, and it is unclear whether the predicted choroideraemia carrier status or high myopia is the main underlying cause of her CNV, although we believe that the former is more likely. The first episode of CNV in her right eye was treated successfully with intravitreal anti-VEGF. However, she experienced four further CNV reactivations in her right eye, all of which were treated successfully with anti-VEGF. At her last follow-up visit to date, Snellen VAs were 6/9 and 3/60 in her right and left eye respectively. Conclusion: This is a unique case of CNV formation in a predicted choroideraemia carrier who also has co-existent high myopia. Prompt treatment of CNV activity with anti-VEGF has been efficacious in prevention of subretinal fibrosis and irreversible vision loss and allowed the patient to continue working in her chosen career.

Endothelial Growth Factor

Choroidal neovascularisation (CNV) is a major cause of vision loss. For more than 10 years, intravitreal injections of anti-vascular endothelial growth factor (VEGF) drugs have been used in the treatment of CNV. While effective, this treatment strategy is limited by the injection burden. Most patients require multiple injections and response levels can vary. Early diagnosis and treatment of CNV can increase the success rate of treatment. There is, therefore, considerable interest in identifying biomarkers both to identify patients most likely to respond to treatment and to facilitate early detection of the condition. In an expert interview, Maurizio Battaglia Parodi of the University Vita-Salute Milan, Italy, discusses the latest advances in CNV.

Endothelial Growth Factor

Vascular endothelial growth factor (VEGF) plays a pivotal role in stimulating the growth of pathological subretinal choroidal neovascularisation (CNV). The increased production of VEGF and subsequent CNV formation can occur in degenerative, inflammatory and vascular diseases of the retina and choroid, often leading to severe visual impairment. Anti-VEGF agents which are readily available today are much better, more potent and longer acting in comparison with previous treatment modalities and therefore have dramatically improved the prognosis of patients with CNV. There are four intravitreal anti-VEGF pharmacotherapies proven by large prospective, multicentre, randomised trials to be effective in the treatment of age-related macular degeneration (AMD)-related CNV: pegaptanib (Macugen®, Eyetech Pharmaceuticals, Palm Beach Gardens, FL), ranibizumab (Lucentis®, Genentech, Inc., South San Francisco, CA), bevacizumab (Avastin®, Genentech, Inc., South San Francisco, CA) and VEGF Trap-Eye (Eylea® Regeneron, Tarrytown, NY). However, there are still many challenges and unanswered questions regarding the optimal anti-VEGF pharmacotherapy agent, the best clinical treatment regimen, the most effective dosage, the optimal injection frequency and the duration of treatment. The heavy burden of frequent injections on the elderly patient population and physicians begs for a simpler way of drug administration or development of more potent compounds.

Background: Corneal neovascularization (CN) is a clue feature of different ocular pathological conditions and can lead to corneal edema and opacification with subsequent vision loss. Vascular endothelial growth factor (VEGF), which plays a key role in new vessels formation, proliferation and migration, was found to be up-regulated in these conditions. Nowadays, it is possible to downregulate the angiogenic process by using anti-VEGF agents administered by different routes. Objective: To evaluate the efficacy, safety and possible future directions of anti-VEGF agents used for the treatment of CNV owing to different aetiologies. Methods: A computerized search of articles dealing with the topic of anti-VEGF therapy in CN was conducted in PubMed, Scopus and Medline electronic databases. The following key phrases were used: anti-VEGF agents, corneal neovascularization, bevacizumab, ranibizumab, vascular endothelial growth factor, angiogenesis. Results: The use of anti-VEGF therapy in the treatment of CN reduced pathological vessel density without causing significant side effects. Various administration routes such as topical, subconjunctival and intrastromal ones are available, and the choice depends on patient and disease characteristics. Much more effectiveness is achieved in case of early administration before mature and wellestablished vessels take place. A combined approach between various drugs including anti-VEGF agents should be adopted in those cases at higher risk of neovascularization recurrence such as chronic long-standing diseases where ischemic and inflammatory stimuli are not definitively reversed. Conclusion: The efficacy and safety of anti-VEGF agents support their adoption into the daily clinical practice for the management of CN.

Abstract This article aims to identify key opportunities for improvement in the diagnosis and treatment of retinal disease, and describe recent innovations that will potentially facilitate improved outcomes with existing intravitreal vascular endothelial growth factor (VEGF) therapies and lay the groundwork for new treatment approaches. The review begins with a summary of the key discoveries that led to the development of anti-VEGF therapies and briefly reviews their impact on clinical practice. Opportunities for improvements in diagnosis, real-world outcomes with existing therapies, long-acting therapeutics and personalised health care are discussed, as well as the need to identify new targets for therapeutic intervention. Low-cost, remote patient screening and monitoring using artificial intelligence (AI)-based technologies can help improve diagnosis rates and enable remote disease monitoring with minimal patient burden. AI-based tools can be applied to generate patient-level prognostic data and predict individual treatment needs, reducing the time needed to optimise a patient’s treatment regimen. Long-acting therapeutics can help improve visual outcomes by reducing the treatment burden. When paired with AI-generated prognoses, long-acting therapeutics enable the possibility of vision loss prevention. Dual-acting drugs may help improve efficacy and/or durability beyond what is possible with anti-VEGF agents alone. Recent developments and ongoing innovations will help build upon the success of anti-VEGF therapies to further reduce vision loss owing to retinal disease while lowering the overall burden of care.

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.

Abstract Background Adenosine and its adenosine 2A receptors (A2AR) mediate the immunosuppressive mechanism by which tumors escape immunosurveillance and impede anti-tumor immunity within the tumor microenvironment. However, we do not know whether the adenosine pathway (CD39/CD73/A2AR) plays a role in renal cell carcinoma (RCC). Therefore, we studied the role of immunosuppression in RCC by assessing the adenosine pathway in patients with RCC treated with anti-vascular endothelial growth factor (anti-VEGF) agents or immune checkpoints inhibitors (ICIs) or both. Methods In 60 patients with metastatic RCC, we examined the expression of CD39, CD73, A2AR, and programmed cell death 1 ligand 1 (PD-L1) immunohistochemically in surgically resected tumor tissues and studied the clinicopathological characteristics of these patients. Patients were treated by cytoreductive nephrectomy with systemic therapy with anti-VEGF agent or a combination of the ICIs anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA4) antibody and programmed cell death 1 (PD-1) antibody. Results Increased expression of A2AR in the primary tumors was associated with metastatic profiles. Patients treated with anti–PD-1 antibody in monotherapy, a combination of anti-PD-1 and anti-CTLA4 antibodies, or anti-VEGF agents showed better response and longer overall survival if the primary tumor had higher PD-L1 expression and lower A2AR expression. In Cox multivariate regression analysis, higher expression of A2AR was associated with shorter overall survival. Conclusions Our findings suggest that the expression of A2AR and PD-L1 in the primary tumors in RCC might predict the outcomes of treatment with anti-VEGF agents and ICIs and that the A2AR pathway might be a molecular target for immunotherapy.

Abstract Background and Aims Intravenous (IV) anti-vascular endothelial growth factor(VEGF) is a potent anti-angiogenic factor for the treatment of solid tumours. While, intravitreal anti-VEGF injection is used in the treatment for macular and retinal diseases. The effects of IV anti-VEGF agents are well documented to cause hypertension, renal impairment and proteinuria. However only few reports showed the significance of intravitreal anti-VEGF injection causing minimal change disease (MCD) and acute kidney injury (AKI). Hence, this study is to determine the outcome of renal function following intravitreal anti-VEGF injection. Method This is a prospective, cross sectional study recruiting patients from ophthalmology day-care operation theatre that were scheduled for intravitreal anti-VEGF injection in University Malaya Medical Centre (UMMC). On the day of the injection of anti-VEGF, patients’ demographic data (age, gender, medical background, medications), blood pressure, height, weight and investigations for serum creatinine and urine protein creatinine ratio (PCR) were collected. Following these, they will receive the intravitreal anti-VEGF as per schedule. All these patients were given a follow-up within 72hours to reassess blood pressure, serum creatinine and urine PCR. Results A total of 90 patients were recruited. However, 15 patients were subsequently excluded as there was no repeated serum creatinine at 72-hours post treatment. Their mean age was 67.25 ± 10.41. Among all, 3 patients had significance increased in serum creatinine (4%) with significance changed of urine PCR post treatment. Table 1 showed baseline parameters prior to treatment and table 2 was post treatment parameters. Higher serum creatinine and proteinuria pre intravitreal anti-VEGF were identified to have higher OR of 1.018 (95% CI 1.001-1.035) (p=0.043) and OR 1.004 (1.000-1.007) (p=0.025) respectively among those who developed AKI. In assessing the association between higher pre-treatment creatinine and proteinuria (independent variable) and development of AKI (dependent variable) estimated by logistic regression with no AKI as a reference group we found that there were no significance. Conclusion Following intravitreal anti-VEGF administration, there were no significant changes in blood pressure. However, 4% from our cohort had AKI and worsening proteinuria at 72 hours post treatment. These patients had higher serum creatinine and proteinuria prior to treatment. However, our study is underpowered to establish the relationship between intravitreal anti-VEGF and development of AKI. Further study with larger sample size and longer-term outcome is needed.

Purpose: The aim of this study was to determine whether multiple intravitreal injections of anti-vascular endothelial growth factor (VEGF) drugs for age-related macular degeneration (AMD) exacerbate systemic arteriosclerosis, using the cardio-ankle vascular index (CAVI) and intima-media thickness (IMT). Methods: We analyzed the data of 45 AMD patients who received intravitreal injections of anti-VEGF drugs (ranibizumab and/or aflibercept) and underwent systemic evaluations at baseline and after treatment. Reevaluation was conducted at ≥12 months from the initial treatment. Results: The total number of intravitreal injections of overall anti-VEGF drugs was significantly correlated with Δserum cystatin C. The cumulative number of aflibercept injections was identified as an independent protective factor for ΔCAVI. An increase in the cumulative number of intravitreal injections of overall anti-VEGF drugs was identified as a protective factor for Δmean IMT. Conclusion: Repeated intravitreal injections of an anti-VEGF drug for AMD may lead to morphological and functional changes in large arteries.
