Exploring ocular fundus morphology in relation to growth in adolescents born moderate‐to‐late preterm

Acta Ophthalmologica, EarlyView.
Abstract Purpose To study ocular fundus morphology and its relation to growth in adolescents born moderate‐to‐late preterm (MLP) and full term. Methods This prospective and population‐based cohort study included 50 MLP adolescents (26 girls, mean age 16.5 years) and 50 full‐term controls (30 girls, mean age 16.7 years).

Retinoid isomerase inhibitors impair but do not block mammalian cone photoreceptor function [PDF]

, 2018
Visual function in vertebrates critically depends on the continuous regeneration of visual pigments in rod and cone photoreceptors. RPE65 is a well-established retinoid isomerase in the pigment epithelium that regenerates rhodopsin during the rod visual ...

Pregnancy as a risk factor for central serous chorioretinopathy: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Purpose Pregnancy induces significant changes in the body, including increased peripheral and choroidal blood perfusion and an increased systemic corticosteroid level. Here, we systematically reviewed the evidence on pregnancy as a risk factor for developing central serous chorioretinopathy (CSC) and conducted a meta‐analysis to obtain a ...

Contribution to the theory of photopic vision: Retinal phenomena [PDF]

Principles of thermodynamics are applied to the study of the ultramicroscopic anatomy of the inner eye. Concepts introduced and discussed include: the retina as a three-dimensional sensor, light signals as coherent beams in relation to the dimensions of ...

Characterization of retinal pigment epithelium layer in healthy and diseased retinas with high‐resolution adaptive optics transscleral flood illumination imaging

Acta Ophthalmologica, EarlyView.
Abstract Purpose The retinal pigment epithelium (RPE) is critical in the pathophysiology of retinal diseases, such as age‐related macular degeneration. Adaptive optics transscleral flood illumination (AO‐TFI) offers rapid, detailed morphometric characterization of the RPE layer.

Induction of dark-adaptive retinomotor movement (cell elongation) in teleost retinal cones by cyclic adenosine 3,5-monophosphate. [PDF]

, 1982
In the teleost retina, the photoreceptors and retinal pigment epithelium (RPE) undergo extensive movements (called retinomotor movements) in response to changes in light conditions and to an endogenous circadian rhythm.

Anterior chamber flare and central macular thickness after trabeculectomy versus after phacoemulsification

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare the inflammatory response in the eye after trabeculectomy to after phacoemulsification, focusing on anterior chamber flare (AC flare) and central macular thickness (CMT). Methods Data from 436 participants in two randomized controlled trials were analysed.

Longitudinal changes in choroidal thickness in high myopia: Correlation with maculopathy progression and visual outcomes

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate longitudinal changes in choroidal thickness (CT) in highly myopic eyes and their correlation with myopic maculopathy progression and visual outcomes. Methods Retrospective cohort study on 1228 eyes from 781 highly myopic patients with a minimum 5‐year follow‐up (mean 11.5 ± 3.1 years).

Volume flow across the isolated retinal pigment epithelium of cynomolgus monkey eyes.

Investigative ophthalmology & visual science, 1988
The retinal pigment epithelium (RPE)-choroid was isolated from cynomolgus monkey eyes with experimental retinal detachments and the volume flow was determined in vitro using Ussing-type chambers. With zero pressure difference across the membrane, retina-to-choroid volume flow was 5.0 microliter/hr/cm2 in eyes with subacute retinal detachments (1-2 ...

The prechoroidal cleft in neovascular age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract The prechoroidal cleft is a lenticular, hypo‐reflective space on optical coherence tomography imaging, located between a band of fibrovascular material underneath the retinal pigment epithelium (RPE) and Bruch's membrane. It occurs in 8%–22% of neovascular age‐related macular degeneration (nAMD) eyes, most often with macular neovascularization
