Advances in deep‐tissue fluorescence imaging through optical clearing: A review

VIEW, EarlyView.
Optical clearing refers to techniques that are used to improve the optical transparency of biological tissues. Optical clearing enables imaging of deeper lying tissues as well as 3D volumetric imaging of whole organs. This review examines reports on the integration of optical clearing with advanced fluorescence imaging techniques, with particular ...

Optical coherence tomography angiography of the macula and optic nerve head: microvascular density and test-retest repeatability in normal subjects

BMC Ophthalmology, 2018
Background Despite the potential usefulness of optical coherence tomography angiography in retinal and optic disc conditions, the reliability of the imaging modality remains unclear.

Optical coherence tomography angiography of the optic disc; an overview

Journal of Ophthalmic and Vision Research, 2017
Different diseases of the optic disc may be caused by or lead to abnormal vasculature at the optic nerve head. Optical coherence tomography angiography (OCTA) is a novel technology that provides high resolution mapping of the retinal and optic disc vessels.

Risk factors for the development of subretinal fluid in the fellow eyes of patients with chronic central serous chorioretinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose To assess the risk of subretinal fluid (SRF) development in the fellow eye of chronic central serous chorioretinopathy (cCSC) patients with unilateral SRF at baseline. Methods Medical records of 334 presumed cCSC patients were retrospectively reviewed.

The oscillatory response of the electroretinogram and neuronal adaptation

Acta Ophthalmologica, EarlyView.
Abstract After more than 50 years, there still remains a challenge and an interest to know more as well as extend and deepen our understanding of the small rapid wavelets, the oscillatory potentials (OPs), of the electroretinogram (ERG) and the neuronal adaptation of the retina.

The impact of systemic long‐term medications for the development of age‐related macular degeneration

Acta Ophthalmologica, EarlyView.
Abstract Purpose Age‐related macular degeneration (AMD) is a leading cause of central vision loss in the elderly; however, the systemic factors that modulate its incidence and progression remain unclear. We sought to determine whether long‐term use of systemic medications, including diabetes and antithrombotic medications, corticosteroids and ...

The optical coherence tomography and microperimetry biomarker evaluation in patients with geographic atrophy (OMEGA) study: Geographic atrophy progression in fundus autofluorescence ‐ OMEGA report 3

Acta Ophthalmologica, EarlyView.
Abstract Purpose To measure the progression of geographic atrophy (GA) in subjects with age‐related macular degeneration (AMD) in a natural history study. Methods We analysed fundus autofluorescence (FAF) images using a semiautomatic method (RegionFinder) to quantify the GA area in a monocentric study.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...
