Secretory autophagy and epithelial‐to‐mesenchymal transition in cadaveric AMD samples: Novel pathways in disease progression

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To examine the presence of secretory autophagy and epithelial–mesenchymal transition (EMT) in the macular retinal pigment epithelium (RPE) of human cadaver eyes with different forms of age‐related macular degeneration (AMD). Methods Human cadaver macula samples representing dry and wet AMD, as well as age‐matched controls, were ...

Low‐contrast visual acuity versus low‐luminance visual acuity in choroideremia

open access: yesClinical and Experimental Optometry, EarlyView., 2020
Clinical relevance Choroideremia is a progressive X‐linked inherited rod‐cone dystrophy. Patients present with nyctalopia and progressive visual field loss, but visual acuity remains well preserved early on. This study showed that low‐luminance visual acuity may be a useful clinical outcome measure during earlier disease stages.

Bleached pigment activates transduction in salamander cones. [PDF]

open access: yes, 1995
We have used suction electrode recording together with rapid steps into 0.5 mM IBMX solution to investigate changes in guanylyl cyclase velocity produced by pigment bleaching in isolated cones of the salamander Ambystoma tigrinum.

A model for de novo pigmentation of amelanotic retinal pigment epithelial cells

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose Retinal Pigment Epithelial (RPE) cells perform critical functions in the visual cycle. Their melanin pigmentation, which is organized into specialized compartments – melanosomes, is highly critical for proper vision. A chemical method to induce pigmentation in a non‐pigmented model of ARPE‐19 cells was applied using L‐DOPA as a ...

Metastatic potential of small posterior uveal melanomas

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To investigate the prevalence of aggressive traits in small posterior uveal melanomas (UM). Methods This retrospective, multicentre cohort study included 804 patients with small posterior UM (≤9 mm in largest basal diameter, ≤3 mm in thickness) from centres in the UK, Germany, and Sweden.

Choroidal vascular hyperpermeability patterns in central serous chorioretinopathy correlate with microperimetry: CERTAIN study report 4

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose This report evaluates the association of three distinct leakage patterns of choroidal vascular hyperpermeability (CVH) on indocyanine green angiography (ICGA), previously correlated with disease chronicity, with retinal sensitivity measured by microperimetry in central serous chorioretinopathy (CSC): unifocal indistinct signs of ...

Real‐world outcomes of aflibercept 8 mg in patients previously treated for neovascular age‐related macular degeneration

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To evaluate visual, anatomical and safety outcomes of aflibercept 8 mg in previously treated patients with neovascular age‐related macular degeneration (nAMD). Methods This retrospective study included nAMD patients switched to aflibercept 8 mg from prior anti‐VEGF therapies at Sahlgrenska University Hospital between February 2024 and ...
