Purpose: To report short-term outcomes of treatment switch to faricimab in real-world patients with aflibercept-resistant neovascular age-related macular degeneration (AMD). Methods: Single-center, retrospective cohort study with chart-review using electronic injection database, electronic medical records, and optical coherence tomography (OCT) data from May to September 2023. Results: A total of 50 eyes of 46 patients were analyzed. Faricimab treatment led to absence of fluid in 32% of the eyes and a reduction of fluid in 84% of the eyes. There was a statistically significant decrease in central retinal thickness (CRT) and pigment epithelial detachment (PED) height in those that responded to the switch (median difference: − 31 μm, IQR: 55, p < 0.0001 and median difference: − 21 μm, IQR: 36, p < 0.0001, respectively) and a statistically significant increase in CRT (median difference: + 19 μm, IQR: 20, p = 0.0143) and no change in PED height (median difference: + 22 μm, IQR: 64, p = 0.1508) in those that did not. Best-corrected visual acuity (BCVA) showed marginal decrease with low statistical significance. No ocular or systemic safety events were observed. Conclusions: Our findings suggest that switching to faricimab is generally safe and effective in patients with neovascular AMD who are otherwise difficult to treat and have residual fluid despite frequent injections with aflibercept. We observed a high rate of morphological response to the treatment switch, improvement of anatomical parameters with about one-third of patients having dry macula following a single injection, and a marginal change in BCVA. Sustainability of these results requires further investigation. Study registration: ClinicalTrials.gov registration number: NCT06124677. Date of registration: 09/11/2023, retrospectively registered.

Treatment of chronic central serous chorioretinopathy (cCSC) remains a topic of controversy. As cCSC is a disease that can wax and wane, treatment efficacy is difficult to assess especially when trials compare active treatments without any placebo/control group. In this study, we systematically reviewed short‐term efficacies of any cCSC treatment tested in randomized controlled trials (RCT) and employed network meta‐analyses to compare to non‐treatment controls. We searched 11 literature databases on 20 March 2022 for RCTs of treatment of cCSC. We identified 17 RCTs including a total of 1172 eyes. Treatments included conventional laser (44 eyes), half‐dose or half‐fluence photodynamic therapy (PDT) (298 eyes), ranibizumab (16 eyes), antioxidants (50 eyes), mineralocorticoid receptor antagonists (187 eyes), rifampicin (91 eyes), selective retina therapy (SRT) (67 eyes) and subthreshold micropulse laser (192 eyes). Compared with controls, significant benefit on complete subretinal fluid resolution was only obtained from half‐dose or half‐fluence PDT (OR: 20.6; 95% CI: 6.3–66.7; p < 0.0001) and conventional laser (OR: 36.4; 95% CI: 2.0–655.7; p = 0.015), and at an order of magnitude lower degree from SRT (OR: 3.4; 95% CI: 1.7–6.8; p = 0.00075). Compared with controls and after sensitivity analyses, significant benefit in the change in best‐corrected visual acuity was only obtained by half‐dose/‐fluence PDT (−0.13 logMAR; 95% CI: −0.20 to −0.06 logMAR; p = 0.00021). In conclusion, three treatment options provide significant improvement over no treatment: half‐dose/‐fluence PDT, conventional laser and to a much lesser degree SRT. Considering that conventional laser can only be applied for extrafoveal leaks, and the long‐term data available for PDT‐based treatments finding persisting treatment results, half‐dose or half‐fluence PDT is the only viable treatment option for patients with cCSC. Shortage issues with verteporfin should not lead to employment of ineffective treatment modalities, as they put patients at unnecessary risk of adverse events.

The aim of this review was to evaluate the comparative efficacy of intravitreal anti‐vascular endothelial growth factor (anti‐VEGF) therapy for neovascular AMD. We searched 12 literature databases for randomised clinical trials (RCT) on anti‐VEGF therapy for neovascular AMD and extracted data on: change from baseline to 12 months in best‐corrected visual acuity (BCVA) and central retinal thickness (CRT), and cumulative number of injections at 12 months. The reference for comparison was monthly ranibizumab. Comparisons were made using network meta‐analyses. Forty‐nine RCTs including 23 257 eyes of 23 257 patients were included. No anti‐VEGF drug or treatment regimen provided a better BCVA response compared to the reference. For CRT, small but statistically significant improvements over the reference were observed for brolucizumab 3 mg (−27.9 μm) or 6 mg (−38.1 μm) in loading dose (LD) then every 8–12 weeks, aflibercept 8 mg in LD then every 12 (−26.9 μm) or 16 weeks (−32.1 μm), faricimab 6 mg in LD then treat‐and‐extend (−18.1 μm) and aflibercept 2 mg in LD then every 8 weeks (−11.3 μm). For the cumulative number of injections, a range of anti‐VEGF drugs and treatment regimens provided a statistically significant and clinically meaningful reduction compared to the reference. When results are considered simultaneously, faricimab 6.0 mg or aflibercept 8.0 mg in a treatment regimen with an LD followed by either a treat‐and‐extend regimen or a fixed 12‐ or 16‐week regimen appears to provide the optimal balance between visual outcomes, anatomical outcomes and the lowest treatment burden. However, studies of the long‐term efficacy of newer anti‐VEGF drugs are warranted.

Deep optic disc drusen (ODD) are located below Bruch’s membrane opening (BMO) and may go undetected due to the challenges in imaging them. The purpose of this study is a head-to-head comparison of currently widely used imaging technologies: swept-source optical coherence tomography (SS-OCT; DRI OCT-1 Triton, Topcon) and enhanced depth imaging spectral-domain optical coherence tomography (EDI SD-OCT; Spectralis OCT, Heidelberg Engineering) for the detection of deep ODD and associated imaging features. The eyes included in this study had undergone high-resolution imaging via both EDI SD-OCT and SS-OCT volume scans, which showed at least one deep ODD or a hyperreflective line (HL). Grading was performed by three graders in a masked fashion. The study findings are based on 46 B-scan stacks of 23 eyes including a total of 7981 scans. For scan images with ODD located above or below the level of BMO, no significant difference was found between the two modalities compared in this study. However, for HLs and other features, EDI SD-OCT scan images had better visualization and less artifacts. Although SS-OCT offers deep tissue visualization, it did not appear to offer any advantage in ODD detection over a dense volume scan via EDI SD-OCT with B-scan averaging.

Introduction: The transition from a normal fundus to one with early drusen (≥20 small hard drusen) to age-related macular degeneration (AMD) in the form of drusen ≥63 μm in diameter is of interest, because small hard drusen may be precursors of large drusen. Study of AMD precursor lesions may provide valuable insight into factors that initiate AMD. Here, the progression of drusen was studied over an interval of 20 years in a population-based twin cohort. Methods: Single-center, 20-year follow-up of 138 twins include biometry, fundus optical coherence tomography, and fundus photography. Macular characteristics were hierarchically classified as (per eye) (1) <20 small hard drusen, (2) ≥20 small hard drusen, (3) drusen ≥63 μm, or (4) ≥20 small hard drusen combined with drusen ≥63 μm. Additive and dominant genetic effects as well as shared and nonshared environmental effects were analyzed in a bivariate biprobit model with a classic liability-threshold approach and polygenic modeling with random effects. Results: Median participant age was 59 (range 41–66) years. Of 25 (18%) cases of incident macular drusen, 7 had ≥20 small hard drusen, and 18 had drusen ≥63 μm at follow-up, whereas no participant had developed both traits simultaneously. Smoking was associated with incident ≥20 small hard drusen (p = 0.04) and incident drusen ≥63 μm (p = 0.003). Having ≥20 small hard drusen at baseline was associated with incident drusen ≥63 μm at follow-up (p = 0.02). Development of drusen ≥63 μm was attributable to 49% genetic effects and 51% environmental effects. Conclusion: The risk of progressing from 0 to 19 small hard macular drusen per eye to having ≥20 small hard drusen or drusen ≥63 μm at follow-up was associated with smoking and genetic predisposition. Having ≥20 small hard drusen in the absence of drusen ≥63 μm at baseline was associated with incident drusen ≥63 μm when examined 20 years later. The study confirms that small hard macular drusen is a forewarning of AMD and that progression to AMD may be hindered by avoidance of smoking.
