Pupil filters, represented by binary phase modulation, have been applied to extend the field of view of a light-sheet fluorescence microscope. Optimization has been used, first numerically to calculate the optimum filter structure and then experimentally, to scale and align the numerically synthesized filter in the microscope. A significant practical extension of the field of view has been observed, making the reported approach a valuable tool on the path to wide-field light-sheet microscopy.

Anterior segment ischaemia following insertion of a PreserFlo Micro-Shunt with mitomycin-C for uncontrolled open angle glaucoma.
BMJ Case Rep
November 2024
Ophthalmology, University Hospitals of Leicester NHS Trust, Leicester, UK.
To our knowledge, this is the first report of anterior segment ischaemia after PreserFlo Micro-Shunt insertion surgery. Our patient developed anterior chamber (AC) activity and keratic precipitates 1 week after surgery. Five weeks after surgery, examination revealed a shallow AC, a distorted pupil with posterior synechiae and surface iris neovascularisation.

We compared the visual performance of ZCB00 ultraviolet light-filtering and ZCB00V violet light-filtering monofocal intraocular lenses (IOLs) (both Johnson & Johnson Surgical Vision) with the same materials and basic design in cataract patients treated from 2011 to 2020. The evaluations were performed 10 weeks after the last surgery for implantation of bilateral lenses ≤ 3 months apart. The ZCB00 and ZCB00V groups included 904 eyes from 452 patients (age 72.

Negligence of public transport drivers due to drowsiness poses risks not only to their own lives but also to the lives of passengers. The designed journey tracker system alerts the drivers and activates potential penalties. A custom EfficientNet model architecture, based on EfficientNet design principles, is built and trained using the Media Research Lab (MRL) eye dataset.

Aims/hypothesis: Several studies have reported associations between specific proteins and type 2 diabetes risk in European populations. To better understand the role played by proteins in type 2 diabetes aetiology across diverse populations, we conducted a large proteome-wide association study using genetic instruments across four racial and ethnic groups: African; Asian; Hispanic/Latino; and European.
Methods: Genome and plasma proteome data from the Multi-Ethnic Study of Atherosclerosis (MESA) study involving 182 African, 69 Asian, 284 Hispanic/Latino and 409 European individuals residing in the USA were used to establish protein prediction models by using potentially associated cis- and trans-SNPs.

Article Synopsis
- Research in biologically inspired artificial vision has resulted in advanced robotic systems that overcome issues like optical aberration and limited field of view, but still struggle with recognizing objects in complex backgrounds and varied lighting conditions.
- This study, inspired by the feline eye, presents an innovative artificial vision system featuring a slit-like aperture and a specially designed reflector that improves object detection in a monocular setup by minimizing excessive light and enhancing photosensitivity.
- The system has been proven effective through theoretical and experimental analyses, showcasing its capability to filter out unnecessary information and detect camouflaged objects in various lighting scenarios, marking a significant leap in monocular camera technology and biomimetic design.
