Article Abstract

Background: Open-top light-sheet microscopy (OT-LSM) is a specialized microscopic technique for the high-throughput cellular imaging of optically cleared, large-sized specimens, such as the brain. Despite the development of various OT-LSM techniques, achieving submicron resolution in all dimensions remains.

Results: We developed a high-resolution open-top axially swept LSM (HR-OTAS-LSM) for high-throughput and high-resolution imaging in all dimensions. High axial and lateral resolutions were achieved by using an aberration-corrected axially swept excitation light sheet in the illumination arm and a high numerical aperture (NA) immersion objective lens in the imaging arm, respectively. The high-resolution, high-throughput visualization of neuronal networks in mouse brain and retina specimens validated the performance of HR-OTAS-LSM.

Conclusions: The proposed HR-OTAS-LSM method represents a significant advancement in the high-resolution mapping of cellular networks in biological systems such as the brain and retina.

Purpose: To compare refractive prediction accuracy using simulated keratometry (SimK) measurements obtained from a Scheimpflug tomographer (Pentacam AXL, Oculus) versus keratometry (K) measurements obtained from an optical biometer utilizing telecentric keratometry (IOLMaster 700 (IOLM700), Carl Zeiss Meditec AG) applied to modern IOL power calculation formulas.

Design: Retrospective accuracy and validity analysis METHODS: Setting: Private practice center STUDY POPULATION: Five hundred eighty-nine eyes with preoperative SimK and K measurements undergoing phacoemulsification and implantation of monofocal IOL (Clareon SY60WF IOL, Alcon Laboratories, Inc.).

Objective: To evaluate the measurement accuracy of 2 swept-source optical biometers, the IOLMaster 700 and the Revo FC 130, in patients diagnosed with cataracts.

Methods: We conducted a prospective, observational and comparative study in patients older than 40 years with cataracts. A single operator performed optical biometry using both devices during the same session.

Existing microscopy approaches are often unable to identify and contextualize rare but biologically meaningful events due to limitations associated with simultaneously achieving both high-resolution imaging and a cm-scale field of view. Here, we present multiscale cleared tissue axially swept light-sheet microscopy (MCT-ASLM), a platform combining cm-scale imaging with targeted high-resolution interrogation of intact tissues in human-guided or autonomous modes. Capable of capturing fields of view up to 21 mm at micron-scale resolution, MCT-ASLM can seamlessly transition to a targeted imaging mode with an isotropic resolution that approaches ∼300 nm.

Retinal and Choroidal Vascular Biomarkers Are Correlated With the Degree of Myopia.

Purpose: To investigate adaptive changes in retinal and choroidal vasculature with increasing retinal surface area in myopia.

Methods: Widefield optical coherence tomography angiography and enhanced depth imaging (EDI)-OCT images of the retina were used to acquire digital images of the choroidal and retinal vasculature in 32 eyes with axial myopia and 14 emmetropic control population eyes. Retinal vessel density was calculated using Otsu's method and used for quantitative comparison of retinal vascular architecture and perfusion ability with increasing retinal surface area.
