AI Article Synopsis
Article Abstract
In this Letter, we report for the first time (to our knowledge) in-vivo volumetric optical coherence microscopy images of skin epidermal cells. We achieved micrometer-class resolution, 2 μm laterally and axially, with an acquisition speed of 23 K A-scans/s and over 90 dB sensitivity to a depth of 1 mm by employing a custom, liquid-lens-based, dynamic-focusing objective, a broadband light source, and a custom, astigmatism-corrected Czerny-Turner spectrometer with a high-speed complementary metal-oxide-semiconductor camera.

Choroidal thickness and vascular density after rhegmatogenous retinal detachment.
Acta Ophthalmol
January 2025
Department of Ophthalmology, Stavanger University Hospital, Stavanger, Norway.
Purpose: To study choroidal thickness (CT) and luminal areas of choroidal vessels in the setting of fovea-off rhegmatogenous retinal detachment (RRD).
Methods: Twenty-seven eyes with RRD were prospectively studied before and after pars plana vitrectomy and SF6 tamponade, using swept-source optical coherence tomography (SS-OCT). CT was measured pre- and postoperatively both subfoveally and in attached macular areas.

J Coll Physicians Surg Pak
January 2025
Department of Stomatology, The Second People's Hospital of Hefei and Hefei Hospital Affiliated to Anhui Medical University, Hefei, Anhui, China.
Objective: To investigate the effects of bulk-fill, resin-based composite types (high or low viscosity) on the internal adaptation of Class V restorations.
Study Design: Experimental study. Place and Duration of the Study: Hefei Stomatological Hospital, Hefei, China, from October 2022 to December 2023.
Acute zonal occult outer retinopathy (AZOOR) complex associated with torpedo retinopathy following COVID-19 recombinant mRNA vaccination: a case report of a rare clinical presentation.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Linkou main branch, Chang Gung Memorial Hospital, Taoyuan, Taiwan.
Background: While vaccination remains crucial in mitigating the impact of the COVID-19 pandemic, several ocular adverse events has been reported, including Acute Zonal Occult Outer Retinopathy (AZOOR) complex.
Case Presentation: A 31-year-old female presented declined best corrected visual acuity (BCVA) and flashes in both eyes three days following second recombinant mRNA COVID-19 vaccine (Moderna). Fundus autofluorescence (FAF) illustrated speckled hyper-AF lesions surrounding right eye torpedo maculopathy site and hyper-AF lesions in the left macula.
Evaluation of macular retinal oximetry across different levels of diabetic retinopathy: a cross sectional study.
BMC Ophthalmol
January 2025
College of Optometry, University of Houston College of Optometry, 4401 Martin Luther King Blvd, 77204-2020, Houston, TX, USA.
Background: This study evaluates retinal oxygen saturation and vessel density within the macula and correlates these measures in controls and subjects with type 2 diabetes (DM) with (DMR) and without (DMnR) retinopathy. Changes in retinal oxygen saturation have not been evaluated regionally in diabetic patients.
Methods: Data from seventy subjects (28 controls, 26 DMnR, and 16 DMR were analyzed.
Structural reversal of disc cupping measured in Bruch's membrane opening-based OCT morphometry after PRESERFLO microshunt implantation for open-angle glaucoma.
BMC Ophthalmol
January 2025
Department of Ophthalmology, Medical Faculty, University Hospital of Cologne, Kerpener Strasse 62, 50937, Cologne, Germany.
Background/ Aims: To analyze the longitudinal change in Bruch's membrane opening minimal rim width (BMO-MRW) and peripapillary retinal nerve fiber layer (pRNFL) thickness using optical coherence tomography (OCT) after implantation of a PRESERFLO® microshunt for surgical glaucoma management in adult glaucoma patients.
Methods: Retrospective data analysis of 59 eyes of 59 participants undergoing implantation of a PRESERFLO microshunt between 2019 and 2022 at a tertiary center for glaucoma management. Surgical management included primary temporary occlusion of the glaucoma shunt to prevent early hypotony.
