Purpose: To compare the efficacies and treatment outcomes of intravitreal anti-VEGF agents and laser therapy in retinopathy of prematurity (ROP).
Methods: A retrospective, non-randomized, comparative study of patients diagnosed with type 1 ROP or aggressive posterior ROP (A-ROP) treated with intravitreal anti-VEGF agents or laser therapy as primary treatment at the People's Hospital of Peking University.
Results: A total of 1,627 eyes of 862 patients were included. In , 399 eyes of 204 patients were diagnosed with A-ROP or zone I type 1 ROP. The initial regression of the anti-VEGF subgroup was better than that of the laser subgroup, and the reactivation rate and rate of progression to retinal detachment were lower than those of the laser subgroup. In , 1,228 eyes of 658 patients were diagnosed with zone II type 1 ROP. The reactivation rate of the laser subgroup was lower than that of the anti-VEGF subgroup. No significant differences were found in the initial regression and the probability of developing retinal detachment. Among the anti-VEGF agents, the reactivation rate in eyes treated with conbercept was much lower than that in eyes treated with ranibizumab. The spherical power and spherical equivalents of eyes treated with laser were significantly higher than those of eyes treated with anti-VEGF agents 1 year after initial treatment.
Conclusions: In contrast to laser therapy, anti-VEGF agents as primary treatments have potential advantages for eyes with zone I type 1 ROP and A-ROP. For eyes with zone II type 1 ROP, laser photocoagulation and anti-VEGF agents therapy showed similar efficacy; however, the rate of reactivation with laser therapy was significantly lower than that with anti-VEGF agents. Among the anti-VEGF agents, the reactivation rate was much lower in eyes treated with conbercept than in eyes treated with ranibizumab. Compared to anti-VEGF agents, laser treated eyes had greater trend to myopia.

Vascular endothelial growth factor (VEGF), also known as VEGF-A, has been linked to various diseases, such as wet age-related macular degeneration (wAMD) and cancer. Even though there are VEGF inhibitors that are currently commercially available in clinical applications, severe adverse effects have been associated with these treatments. There is still a need to develop novel VEGF-based therapeutics against these VEGF-related diseases.

Aflibercept and brolucizumab, two anti-VEGF agents used as intravitreal injections in ophthalmology, differ significantly in molecular weight (aflibercept-115 kDa and brolucizumab-26 kDa). Using aqueous humor samples collected after drug administration, we measured and performed a comparative analysis of pharmacokinetics and half-lives of these drugs in the human eye. Since the quantification of monoclonal antibodies (mAbs) using antigen-antibody reactions, such as ELISA, is influenced by endogenous ligands or anti-drug antibodies, we employed nano-surface and molecular-orientation limited proteolysis (nSMOL), combined with liquid chromatography-tandem mass spectrometry (LC-MS/MS), for accurate measurements.

Branch retinal vein occlusion (BRVO) is a common retinal vascular condition and a significant contributor to vision loss worldwide, particularly in middle-aged and elderly populations. This review synthesizes current knowledge on the epidemiology, pathogenesis, and clinical features of BRVO, alongside recent advancements in diagnostic and therapeutic strategies. BRVO is approximately four times more prevalent than central retinal vein occlusion (CRVO) and often leads to significant vision impairment.

Age-related macular degeneration (AMD) is one of the leading causes of central vision loss in the elderly population. Bevacizumab, a full-length humanized monoclonal anti-VEGF antibody, is commonly used off-label drug to treat AMD. However, the dosing regimen of bevacizumab and other anti-VEGF antibodies requires monthly intravitreal injections followed by regular intravitreal injections at 4-16-week intervals.

Background: Choroidal neovascular membranes (CNVM) associated with optic nerve head drusen (ONHD) are rare but vision threatening. A variety of treatments, including laser photocoagulation, subretinal surgery, and anti-VEGF injections, are effective but pose risks, particularly in pediatric patients, underscoring the need for a comprehensive review.
Methods: A systematic review was conducted using PubMed, Embase, and Web of Science.
