Real-World Effectiveness, Treatment Pattern, and Safety of Ranibizumab in Korean Patients with Neovascular Age-Related Macular Degeneration: Subgroup Analyses from the LUMINOUS Study

A real-world study assessing the impact of retinal fluid on visual acuity outcomes in patients with neovascular age-related macular degeneration in Korea

To evaluate the real-world treatment outcomes in patients with neovascular age-related macular degeneration (nAMD) in Korea, focusing on retinal fluid resolution. This multi-institutional retrospective chart review study, analyzed medical records of patients with nAMD (age ≥ 50 years) who received their first anti-vascular endothelial growth factor (VEGF) treatment in ophthalmology clinics across South Korea between January 2017 and March 2019. The primary endpoint was the proportion of patients with retinal fluid after 12 months of anti-VEGF treatment. The association between fluid-free period and VA gains was also evaluated. A total of 600 patients were enrolled. At baseline, 97.16% of patients had retinal fluid; after 12 months of anti-VEGF treatment, 58.10% of patients had persistent retinal fluid. VA improvements were relatively better in patients with absence of retinal fluid compared with presence of retinal fluid (+ 12.29 letters vs. + 6.45 letters at month 12; P < .0001). Longer duration of absence of retinal fluid over first 12 months correlated with better VA gains at month 12 (P < .01). More than half of the study patients with nAMD had retinal fluid even after 12 months of treatment with their current anti-VEGF. Presence of retinal fluid was associated with relatively worse VA outcomes.

Comparison of visual outcomes of polypoidal choroidal vasculopathy and typical neovascular age-related macular degeneration-up to 10 years of follow-up

PURPOSE

To investigate long-term visual outcomes of patients with polypoidal choroidal vasculopathy (PCV) and typical neovascular age-related macular degeneration (nAMD) in the real-world setting.

METHODS

Retrospective, multicenter, noninterventional consecutive cohort study. Two hundred eighty-five eyes of 261 patients with PCV and 902 eyes of 877 patients with typical nAMD, who could be followed up 1 year or longer from 2005 to 2018, were included. Mean changes in best-corrected visual acuity (BCVA) from baseline in the PCV and the typical nAMD groups were compared.

RESULTS

Mean follow-up period of total patients was 4.3 ± 2.8 (1-10) years. Baseline BCVA was better in the PCV group than that in the typical nAMD group (0.59 ± 0.52 versus 0.79 ± 0.63 logMAR, p < 0.001). The mean changes in BCVA from baseline in the PCV and nAMD group were +2.1 and -0.1 letters at 1 year, -0.2 and -3.7 letters at 3 years, -3.9 and -10.5 letters at 5 years and - 8.7 and - 12.1 letters at 7 years, respectively. Before 2006, the initial BCVA was sustained for approximately 1 year in eyes with PCV and for less than half year in eyes with typical nAMD. However, after 2007, when anti-VEGF agents were available, the initial BCVA was sustained for 4 years in eyes with PCV, while it was sustained for 1 year in eyes with typical nAMD.

CONCLUSION

In the real-world, long-term BCVA deteriorated in both PCV and typical nAMD groups, but the PCV group showed better visual outcomes than the typical nAMD group.

Treat-and-Extend Regimens for the Management of Neovascular Age-related Macular Degeneration and Polypoidal Choroidal Vasculopathy: Consensus and Recommendations From the Asia-Pacific Vitreo-retina Society

PURPOSE

Review and provide consensus recommendations on use of treat-and-extend (T&E) regimens for neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV) management with relevance for clinicians in the Asia-Pacific region.

METHODS

A systematic search of MEDLINE, EMBASE, and Cochrane databases, and abstract databases of the Asia-Pacific Vitreo-retina Society, European Society of Retina Specialists, American Academy of Ophthalmology, and Controversies in Ophthalmology: Asia-Australia congresses, was conducted to assess evidence for T&E regimens in nAMD. Only studies with ≥100 study eyes were included. An expert panel reviewed the results and key factors potentially influencing the use of T&E regimens in nAMD and PCV, and subsequently formed consensus recommendations for their application in the Asia-Pacific region.

RESULTS

Twenty-seven studies were included. Studies demonstrated that T&E regimens with aflibercept, ranibizumab, or bevacizumab in nAMD, and with aflibercept in PCV, were efficacious and safe. The recommendation for T&E is, after ≥3 consecutive monthly loading doses, treatment intervals can be extended by 2 to 4 weeks up to 12 to 16 weeks. When disease activity recurs, the recommendation is to reinject and shorten intervals by 2 to 4 weeks until fluid resolution, after which treatment intervals can again be extended. Intraretinal fluid should be treated until resolved; however, persistent minimal subretinal fluid after consecutive treatments may be tolerated with treatment intervals maintained or extended if the clinical condition is stable.

CONCLUSIONS

T&E regimens are efficacious and safe for nAMD and PCV, can reduce the number of visits, and minimize the overall burden for clinicians and patients.
