High-fidelity Image Restoration of Large 3D Electron Microscopy Volume.
Microsc Microanal
November 2024
Volume electron microscopy (VEM) is an essential tool for studying biological structures. Due to the challenges of sample preparation and continuous volumetric imaging, image artifacts are almost inevitable. Such image artifacts complicate further processing both for automated computer vision methods and human experts.

- A pilot study evaluated the safety and effectiveness of the Primary Eyecare Glaucoma Service (PEGS) for low-risk glaucoma patients treated in primary care optometry.
- Out of 98 patients, 93.8% remained suitable for primary care monitoring, with only 4.9% needing referral back to secondary care, and a high agreement rate of 97.8% was found between primary and secondary care management plans.
- Patient satisfaction was 100%, optometrists felt confident in their care role, and the service significantly reduced carbon emissions by lowering patient travel distance compared to hospital visits.
Article Synopsis
- * Analyzed data from 207 eyes over two years showed no significant differences in visual acuity, intraocular pressure, or glaucoma medication use between the two groups, though more cataracts were noted in optometrist-treated eyes.
- * Overall, the study concluded that both optometrists and ophthalmologists have similar SLT treatment outcomes, but ophthalmologist-treated eyes had higher medication use and lower rates of subsequent surgery.
The size of image volumes in connectomics studies now reaches terabyte and often petabyte scales with a great diversity of appearance due to different sample preparation procedures. However, manual annotation of neuronal structures (e.g.

Whilst many studies examined safety and clinical effectiveness, there is a paucity of qualitative research evaluating enablers and barriers for optometrists delivering glaucoma care. The aims of this study are to investigate qualitatively, and from a multi-stakeholder perspective whether optometric glaucoma care is accepted as an effective alternative to traditional models and what contextual factors impact upon their success.
