    Assessment of local sensitivity in incomplete retinal pigment epithelium and outer retinal atrophy (iRORA) lesions in intermediate age-related macular degeneration (iAMD) by Frank G Holz, Marlene Saßmannshausen, Thomas Ach, Leon von der Emde, Julius Ameln, Alessandra Carmichael-Martins, Wolf M Harmening

    Published 2024-03-01
    “…However, the corresponding functional impact of these precursor lesions is unknown and needs to be established.Methods and analysis We present a cross-sectional study of four patients with intermediate AMD employing clinical-grade MAIA (stimulus size: 0.43°, ~125 µm) and adaptive optics scanning light ophthalmoscope (AOSLO, stimulus size 0.07°, ~20 µm) based microperimetry (MP) to assess the specific impact of iRORA lesions on retinal sensitivity.Results AOSLO imaging showed overall reduced photoreceptor reflectivity and patches of hyporeflective regions at drusen with interspersed hyperreflective foci in iRORA regions. …”

    Valley-Hall slow-light waveguide states with dual-band in all-dielectric valley photonic crystals by Liu He, Jianquan Yao

    Published 2025-01-01
    “…The slow-light waveguide states protected by topology could be used in strengthening interaction between light and matter, so they can be used for realizing a lot of unique physical optics phenomena and interesting applications. In this work, we consider a kind of all-dielectric valley photonic crystals (VPCs) with honeycomb lattice, realize dual-band photonic valley-Hall kink states at the stacking interface composed of two VPCs with mirror symmetry through breaking the parity-reversal symmetry of photonic system, such as low-frequency and high-frequency valley-Hall kink states. …”
