    Abstract To solve the problem of the narrow viewing zone in electro-holography, we propose a method using eye-tracking and a property of holography where the viewing zone varies with the angle of the reconstruction light. The method can enlarge the viewing zone without moving the optical elements for higher-order diffracted light removal and high-refresh-rate devices. The size of the reconstructed image is also enlarged using lenses. We conducted an experiment to validate the effectiveness of our method, and the results indicate that the viewing zone was enlarged by 1.44 times and the size of the reconstructed image was enlarged by 1.49 times.

    Abstract A computer-generated hologram (CGH) enables the display of virtual images and videos as well as the communication and storage of holographic data. The point-based method, which is a CGH-calculation method for representing the surface of an object as a set of point-light sources, has not been sufficiently studied in terms of realistic representation. This paper proposes a CGH-calculation method for realistic rendering using ray tracing to be used with a point-based method. Experiments were conducted with an optical system to confirm the effectiveness of the proposed method in terms of hidden-surface removal in mirror images and its implementation on multiple mirror surfaces. The results indicate that the proposed method enabled hidden-surface removal with continuous parallax and reflection on mirror surfaces.

    Abstract The neuromuscular junction (NMJ) forms centrally in myotubes and, as the only synapse between motor neuron and myotube, are indispensable for motor activity. The midmuscle formation of NMJs, including midmuscle-restricted expression of NMJ-related genes, is governed by the muscle-specific kinase (MuSK). However, mechanisms underlying MuSK-mediated signaling are unclear. Here, we find that the

    Abstract Background: The optic tectum is the main visual processor of nonmammalian vertebrates and relays visual information from the eye to the telencephalon via the tectofugal pathway. In the development of the avian optic tectum, while the multipolar neurons are arranged by tangential migration, the behavior of individual cells in tangential migration, neural differentiation, and cell fate remain unclear. Here, we pursued the transition of tangentially migrating cells and their involvement in visual circuit formation during chick development.
    Results: After tangential movement along the axons, the migrating cells relocated to the upper layers and turned back upon differentiation toward the multipolar neurons. The multipolar neurons are destined to differentiate into the stratum griseum central (SGC) neurons with the large dendritic field, which form the tectorotundal projection. Trans-synaptic virus labeling demonstrated that the tangentially migrating cells eventually participate in the tectofugal visual pathway.
    Conclusions: These results indicate that tangential migration is a crucial process in the formation of the tectofugal visual pathway during the development of the optic tectum.

    Abstract Introduction: Here, we report a case of severe intraocular inflammation (IOI) and prominent choroidal thinning following the initial intravitreal brolucizumab injection (IVBr).
    Case presentation: The patient was a 75-year-old Japanese man with type 2 age-related macular degeneration of both eyes. Until 2015, he had undergone two intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections and two photodynamic therapies in his right eye. His decimal best-corrected visual acuity (BCVA) was 0.1 in the right eye and 0.1 in the left eye. Central choroidal thickness (CCT) measured 240 μm in his right eye. IVBr was administered to the right eye. The patient reported pain in the right eye 23 days after the injection. On day 26, panuveitis and retinal vasculitis were observed in the right eye. CCT measured 436 μm. On the same day, a sub-tenon triamcinolone injection was administered. On day 42, retinal inflammation remained at a similar level. The CCT decreased to 164 μm. On day 68, the intraocular pressure (IOP) in the right eye increased to 39 mm Hg, and IOI persisted. On day 89, the patient's eye pain disappeared, and the IOP decreased to 13 mm Hg. On day 225, the IOI and symptoms were completely resolved. The decimal BCVA was 0.04 in the right eye, and CCT measured 84 μm.
    Conclusion: Brolucizumab is a highly effective anti-VEGF drug; however, it has the potential to induce inflammation in tissues adjacent to the retina and may occasionally cause irreversible sequelae.

    Abstract We aimed to evaluate the safety and efficacy of office-based probing with dacryoendoscopy under local anesthesia for congenital nasolacrimal duct obstruction (CNLDO). This single-institution study retrospectively reviewed data on 72 eyes of 64 consecutive children (38 boys, 43 eyes; 26 girls, 29 eyes), aged between 6 and 17 (mean age: 10.0 ± 2.7) months with suspected CNLDO, from July 2016 to February 2022. These patients underwent probing with dacryoendoscopy under local anesthesia. CNLDO was diagnosed clinically based on the presence of epiphora and sticky eyes due to mucous discharge commencing within the first 3 months of life, increased tear meniscus height, and fluorescein dye disappearance test results. A total of 63 of the 72 eyes had narrowly defined CNLDO, and 9 eyes had other types of obstructions. The intervention success rate was 100% (63/63 eyes) for patients with typical CNLDO and 97.2% (70/72 eyes) for the entire study cohort. Moreover, CNLDO was classified into five types based on the features of the distal end of the nasolacrimal duct. Probing with dacryoendoscopy is safe and yields a high success rate in pediatric patients with CNLDO. This is the first study to assess the safety and efficacy of probing with dacryoendoscopy under local anesthesia in pediatric patients with CNLDO.
