Review, Journal: Treatment of radiation maculopathy and radiation-induced macular edema: a systematic review. (Pubmed Central) - Mar 8, 2022 Intravitreal dexamethasone implant may be an option for those with suboptimal response or contraindications to anti-VEGF agents. Possible preventive treatments that require future study are intravitreal bevacizumab and ranibizumab, peripheral laser photocoagulation, and subtenon triamcinolone acetonide.

Biomarker, Clinical, Journal: Proteomic changes of aqueous humor in proliferative diabetic retinopathy patients treated with different intravitreal anti-VEGF agents. (Pubmed Central) - Mar 5, 2022 In summary, we discovered that ALDH3A1 was a previously unreported protein that was related to angiogenesis and was differentially expressed in the three anti-VEGF treatment groups, suggesting that it may be a new target for PDR therapy. The described proteomic changes in the AH of PDR patients treated with different anti-VEGF agents provide novel targets which may explain the heterogeneity of anti-VEGF treatment responses in these patients, providing a robust foundation for future studies of PDR pathogenesis.

Journal: Blocking of VEGF-A is not sufficient to completely revert its long-term effects on the barrier formed by retinal endothelial cells. (Pubmed Central) - Mar 5, 2022 Interestingly, the specific VEGFR2 inhibitor nintedanib normalized the lowered CI when added to iBREC pre-treated with VEGF-A for one day, but failed to do so when cells had been exposed to the growth factor for six days...To counteract these effects of VEGF-A, brolucizumab or ranibizumab was added after one day, resulting in recovery of the then lowered CI to normal values within a few hours...Taken together, barrier dysfunction induced by VEGF-A results from deregulated para- and transcellular flow but the precise nature or magnitude of underlying changes on a molecular level clearly depend on the time of exposure, evolving into a stage of VEGF-A-independent barrier impairment. These findings also provide a plausible explanation for resistance to treatment with VEGF-A antagonists frequently observed in clinical practice.

Journal: Mfsd2a overexpression alleviates vascular dysfunction in diabetic retinopathy. (Pubmed Central) - Mar 3, 2022 However, about 27% of the patients have a poor visual outcome, with 50% still having edema after two years' treatment of diabetic macular edema (DME) with ranibizumab...Moreover, Mfsd2a overexpression in combination with the DHA diet obviously reduced abnormal retinal neovascularization and vascular leakage, which is more effective than Mfsd2a overexpression alone. These results suggest that DHA therapy failure in some DR patients is linked to low expression of Mfsd2a, and the combination of Mfsd2a overexpression and DHA therapy may be an effective treatment.

Journal: Monoclonal antibodies in diabetic retinopathy. (Pubmed Central) - Mar 3, 2022 Relevant clinical studies were imported. Future direction includes detection of more therapeutic targets considering other components of DR pathophysiology and shared pathogenesis of DR and neurodegenerative diseases such as Parkinson's disease and Alzheimer's disease, the treat-and-extend regimen, and new ways of drug delivery and other routes of ocular drug administration.

(Pubmed Central) - Mar 1, 2022 Also, there was no significant change in fibrinogen, lymphocyte count, MLR, HDL-c, UA, PLR, and platelet count values in both groups. Compared to IVR, IVA treatment had a small but significant effect on systemic inflammatory and cardiovascular biomarkers.

Clinical, Observational data, Journal: Intravitreal anti-VEGF use in France: a cross-sectional and longitudinal Nationwide observational study. (Pubmed Central) - Mar 1, 2022 Less frequent dispensations and surveillance examinations were observed than in monthly schemes applied in registration trials for IVT anti-VEGF. These results may indicate a lack of systematic monitoring associated with fewer injections and/or clinicians' preference for more flexible and personalized injection schemes than those originally recommended.

Fixed q8 ranibizumab, q8 bevacizumab, q12 aflibercept, or q10 brolucizumab regimens may produce adequate intraocular VEGF inhibition.

Pricing, Journal: Competition law and pricing among biologic drugs: the case of VEGF therapy for retinal diseases. (Pubmed Central) - Feb 26, 2022 We propose mechanisms for anticipating and facilitating the market introduction of biosimilars, as well as changes to the pricing model in Medicare that can promote use of cost-effective therapies. Reforms such as empowering Medicare to negotiate drug prices may help ensure that introduction of new biologics and biosimilars for AMD will lower spending and increase patient access.

Clinical, Journal: Disease-modifying effects of ranibizumab for central retinal vein occlusion. (Pubmed Central) - Feb 19, 2022 Ranibizumab for CRVO resulted in beneficial disease-modifying effects through a reduction in retinal hemorrhage, neovascularization, and papillary swelling. These findings may form the basis for future work in the development of a treatment response or severity scale for eyes with CRVO.

Journal: Bilateral blindness after uneventful brolucizumab injection for macular degeneration. (Pubmed Central) - Feb 19, 2022 We do not recommend performing bilateral brolucizumab injections until more data is available regarding the mechanism of brolucizumab-induced vasculitis. From a clinical point of view, we find it difficult to justify the use of brolucizumab when there are other well-known agents, such as ranibizumab and aflibercept, which have better safety profiles and comparable efficacy.
