Factors Associated with Success of Switching to Faricimab for Neovascular Age-Related Macular Degeneration Refractory to Intravitreal Aflibercept.

We investigated the factors associated with the success of switching to faricimab for type 1 macular neovascularization (MNV) refractory to intravitreal aflibercept (IVA). This retrospective cohort study included patients with type 1 MNV who were switched to faricimab because they were refractory to IVA at two centers. The primary endpoint was a more than two-week extension of the treatment interval after 6 months. In addition, factors related to the success or failure of extension and visual and anatomical outcomes were assessed. The analysis included 43 eyes from 43 patients. Extended dosing intervals of >2 weeks were identified in 14 eyes (32.6%). A short dosing interval before switching, absence of polypoidal lesions, and thin central choroidal thickness before switching were identified as factors involved in successful extension. For patients with refractory type 1 MNV, switching to faricimab is a safe and potential option to extend existing dosing intervals.

INVESTIGATION OF INCIDENCE AND CAUSES OF ACUTE VISION LOSS DURING ANTI-VASCULAR ENDOTHELIAL GROWTH FACTOR THERAPY FOR NEOVASCULAR AGE-RELATED MACULAR DEGENERATION DURING A FOUR-YEAR FOLLOW-UP.

PURPOSE: To investigate the incidence, risk factors, and outcomes of patients with age-related macular degeneration who experienced acute vision loss despite periodic injections of anti-vascular endothelial growth factor treatment for 4 years. METHODS: This retrospective cohort study included patients who were diagnosed with treatment-naive neovascular age-related macular degeneration and completed a 4-year follow-up. The incidence and risk factors for the occurrence of three or more lines of visual loss at every checkup were investigated. RESULTS: The analysis included 76 eyes of 76 patients. Acute vision loss occurred in 30 eyes (39.5%) over 4 years. Lower baseline best-corrected visual acuity and disrupted ellipsoid zone were independent predictors of vision loss occurrence. Although the causes and timing of visual acuity loss varied, retinal pigment epithelium tears were observed only in the first year. Most patients (86.7%) who experienced vision loss recovered their vision to pre-loss levels at least once; however, the final best-corrected visual acuity was worse than that in the group that did not experience acute vision loss. CONCLUSION: Approximately half of the patients with age-related macular degeneration experienced acute vision loss during a 4-year follow-up, despite continuous anti-vascular endothelial growth factor treatment. Most patients recovered from vision losses temporarily; however, they experienced worse visual outcomes subsequently.

Recurrence of neovascular age-related macular degeneration after cessation of treat and extend regimen.

The appropriate timing of treatment cessation after treat and extend (TAE) regimen for age-related macular degeneration has not been established. This study aimed to investigate the incidence and risk factors of recurrence after cessation of the TAE regimen. We included patients who received and discontinued the TAE regimen, after extension of the treatment interval to ≥ 12 weeks. Forty-nine patients were included in the study. The estimated recurrence rates were 33% at 1 year and 48% at 2 years after treatment cessation, respectively. Good visual acuity at cessation and a large number of injections in the 6 months before cessation were significant risk factors. Higher chances of recurrence were associated with < 0.1 logarithm of the minimum angle of resolution (logMAR) at cessation (P < 0.002). Meanwhile, five patients with visual acuity ≥ 1.0 logMAR at cessation did not show recurrence. Among the 25 recurrences, two lines of vision loss were noted in only two cases after resumed treatment. This study confirmed the importance of the number of injections in reducing recurrence and the association between visual acuity and recurrence. Recurrence is generally well-controlled with resumed treatment.

Initial treatment for polypoidal choroidal vasculopathy: Ranibizumab combined with photodynamic therapy or fixed-dosing aflibercept monotherapy.

PURPOSE: To compare the 2-year outcomes of combination therapy using intravitreal ranibizumab and photodynamic therapy with those of fixed-dosing intravitreal aflibercept monotherapy as initial treatment for treatment-naïve polypoidal choroidal vasculopathy. METHODS: We retrospectively reviewed 63 eyes of 61 patients with treatment-naïve polypoidal choroidal vasculopathy who had undergone at least 24 months of follow-up. In total, 43 eyes underwent intravitreal ranibizumab-photodynamic therapy combination therapy and 20 eyes underwent fixed-dosing intravitreal aflibercept monotherapy. Visual outcomes and the number of treatments were compared between the two groups. RESULTS: The mean logarithm of minimal angle of resolution best-corrected visual acuity significantly improved from 0.48 ± 0.41 at baseline to 0.30 ± 0.47 at 24 months in the intravitreal ranibizumab-photodynamic therapy group (p = .0002) and from 0.30 ± 0.18 at baseline to 0.16 ± 0.18 at 24 months in the intravitreal aflibercept group (p = .004), with no significant intergroup differences. The mean number of intravitreal ranibizumab or intravitreal aflibercept injections over 24 months was 5.7 ± 4.5 in the intravitreal ranibizumab-photodynamic therapy group and 12.2 ± 3.8 in the intravitreal aflibercept group (p < .0001). CONCLUSION: The intravitreal ranibizumab-photodynamic therapy combination therapy was noninferior to fixed-dosing intravitreal aflibercept monotherapy in improving visual acuity and required fewer injections.

Comparison of corneal safety and intraocular pressure-lowering effect of tafluprost ophthalmic solution with other prostaglandin ophthalmic solutions.

PURPOSE: The benzalkonium chloride (BAK) content of tafluprost ophthalmic solution (Tapros(®): tafluprost) has been reduced to balance corneal safety and preservative effectiveness (old formulation: 0.01%; new formulation: 0.001%). However, no reports have been published on its clinical effect. Therefore, we conducted a clinical research study to compare the safety of BAK-reduced tafluprost on the ocular surface with other prostaglandin ophthalmic solutions. METHODS: This clinical study included 28 glaucoma patients (28 eyes) with a treatment history of latanoprost ophthalmic solution (Xalatan(®)) or travoprost ophthalmic solution (Travatan Z(®)), who presented with corneal epithelial disorders. The subjects were switched to BAK-reduced tafluprost, and its effect on the ocular surface was examined after 1 and 2 months of treatment [using fluorescein staining score, hyperemia, tear film breakup time, and intraocular pressure (IOP) lowering]. RESULTS: In all analyzed subjects (N=27), the fluorescein staining score was significantly improved after switching to BAK-reduced tafluprost (P<0.0001). Conversely, the IOP-lowering effect was not notably changed. The subjects switched from latanoprost (n=10) showed significant improvement in fluorescein staining score (P<0.05) as well as in IOP lowering (P<0.01). The subjects switched from travoprost (n=17) also showed significant improvement in fluorescein staining score (P<0.001), but without a significant change in IOP lowering. CONCLUSIONS: Tafluprost with reduced BAK has potential as a superior antiglaucoma drug, not only for its IOP-lowering effect, but also for its good corneal safety profile.
