Special Issue Information

Dear Colleagues,

Retinal diseases are among the most common causes of irreversible blindness. In older adults, it is often the late stage of age-related macular degeneration (AMD), while in working-age individuals, diabetic retinopathy, chronic central serous chorioretinopathy, secondary neovascularizations, or a variety of genetic diseases are more frequently responsible. Since the introduction of anti-VEGF therapy, the prognosis for patients with neovascularizations has significantly improved. However, there is also a great variability in disease progression, with some patients requiring only a few treatments and maintaining good vision in the long term, while others need monthly therapy for decades and experience a significant decline in vision due to complications such as macular hemorrhages, tears of the retinal pigment epithelium, or atrophy of photoreceptors and pigment epithelial cells. Especially with the development of new anti-VEGF agents, the identification of biomarkers that can enable more individualized therapy would be desirable. This also applies to patients with diabetic retinopathy and diabetic macular edema, as well as patients with secondary neovascularization, who are currently treated non-specifically with the same substances. Additionally, with the approval of complement inhibitors, treatment for geographic atrophy (GA) is now available. Even in this late form, several different disease patterns with varying progression rates are already known. Further identification of individual biomarkers could also improve therapy management here. This Special Issue of the Journal of Personalized Medicine aims to present outstanding research dedicated to the individualized investigation of biomarkers for disease progression or therapy response in retinal diseases.

Objectives: To evaluate the efficacy of faricimab in patients with neovascular age-related macular degeneration (nAMD) that did not respond to other VEGF inhibitors. Methods: This retrospective study included the eyes of patients diagnosed with nAMD who had been switched to faricimab treatment due to the persistence of intraretinal fluid (IRF) and/or subretinal fluid (SRF), despite monthly anti-VEGF treatment with aflibercept, bevacizumab, or ranibizumab using the treat and extend regimen, and who had received at least three faricimab injections following the switch. Best-corrected visual acuity (BCVA) measurement and optical coherence tomography (OCT) analysis were performed at each visit, and the OCT results were graded by two independent readers. Results: We included 41 eyes of 39 patients (21 male, 18 female) with a mean age of 80.5 ± 8.1 years. The median duration of anti-VEGF treatment prior to the switch to faricimab was 5.0 years, with a median of 53 injections. Complete resolution of IRF and SRF was observed after the first dose of faricimab in 12 eyes (29.3%) and after the third dose in 15 eyes (36.6%). Twenty-eight eyes reached a follow-up time after a switch of at least 12 months, with a median of 10 faricimab injections. Of these 28 eyes, 10 eyes (35.7%) exhibited complete IRF/SRF resolution; treatment intervals were extended beyond 4 weeks in 21 eyes (80.7%), and 8 eyes (28.6%) presented complete IRF/SRF resolution under extended treatment intervals at month 12. Central retinal thickness after 12 months was reduced from a median of 368.0 µm to 297.5 µm (p < 0.001), and the BCVA remained stable (p = 0.057). No adverse events were reported throughout the entire treatment period. Conclusions: In nAMD patients with poor anti-VEGF treatment response, complete and fast fluid resolution and the extension of treatment intervals can be reached by switching to faricimab, even after years of prior unsuccessful therapy.

Background/Objectives: This study evaluates the impact of anti-vascular endothelial growth factor (anti-VEGF) treatment on neovascular age-related macular degeneration (nAMD) with and without pigment epithelial detachment (PED) over a one-year period. Methods: Conducted at a tertiary referral center in Taiwan, this retrospective analysis included 88 eyes treated with intravitreal aflibercept injections. Patients were categorized into four groups based on the presence or absence of PED at baseline and 12 months post-treatment. Results: Significant reductions in central macular thickness (CMT) and PED height were observed, although no statistical difference was found in best-corrected visual acuity (BCVA). The presence or type of PED did not negatively impact visual outcomes. Among nAMD patients with persistent PED throughout the first year of anti-VEGF treatment, linear regression analysis showed that mixed-type PED revealed poor final BCVA compared to those with serous PED. The analysis also identified older age and poorer initial BCVA as predictors of less favorable visual outcomes. Conclusions: This study highlights the effectiveness of anti-VEGF therapy in real-world settings and offers insights into factors influencing visual outcomes for nAMD patients with PED. Full article
