Visual outcome including visual field defects after treatment of paediatric optic pathway glioma: A nationwide cohort study

Acta Ophthalmologica, EarlyView.
Abstract Purpose To examine long‐term visual impairment and visual field examination (VF) after diverse treatments for paediatric optic pathway glioma (OPG), and to determine prognostic factors for long‐term severe visual impairment or blindness. Methods A nationwide retrospective cohort study (1995–2018) was performed on paediatric OPGs that received ...

Combining optical coherence tomography with visual field data to rapidly detect disease progression in glaucoma: a diagnostic accuracy study

Health Technology Assessment, 2018
Background: Progressive optic nerve damage in glaucoma results in vision loss, quantifiable with visual field (VF) testing. VF measurements are, however, highly variable, making identification of worsening vision (‘progression’) challenging. Glaucomatous

Preperimetric glaucoma

Российский офтальмологический журнал, 2021
Recently, much literature data is available on the issue of diagnosis of preperimetric glaucoma (PPG), but no recognized algorithms of detecting primary open-angle glaucoma (POAG) at this stage have been developed, and there is no general opinion as to ...

Effect of time to initiation and dose of methylprednisolone on outcome in multiple sclerosis‐related optic neuritis

Clinical and Experimental Neuroimmunology, EarlyView.
Abstract Objectives It is known that the benefit of intravenous methylprednisolone (IVMP) in multiple sclerosis‐related optic neuritis (MS‐ON) is limited to an accelerated recovery. We aimed to evaluate the impact of time from symptoms onset to IVMP initiation and of IVMP dose on visual recovery among people with MS‐ON.

RetiNerveNet: Using Recursive Deep Learning to Estimate Pointwise 24-2 Visual Field Data based on Retinal Structure [PDF]

arXiv, 2020
Glaucoma is the leading cause of irreversible blindness in the world, affecting over 70 million people. The cumbersome Standard Automated Perimetry (SAP) test is most frequently used to detect visual loss due to glaucoma. Due to the SAP test's innate difficulty and its high test-retest variability, we propose the RetiNerveNet, a deep convolutional ...

Detecting Glaucoma in Highly Myopic Eyes From Fundus Photographs Using Deep Convolutional Neural Networks

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background High myopia (HM) is a major risk factor for glaucoma. However, glaucomatous optic neuropathy is often undiagnosed owing to atypical structural alterations with axial elongation. Moreover, an algorithm to detect glaucoma in highly myopic eyes has not yet been reported.

Eyes Offshore: Reporting the Eye Health Needs of Refugees and Asylum Seekers in Australia's Offshore Detention Centres

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background In the last two decades, over 250 000 refugees and asylum seekers have arrived in Australia, many of whom experience significant health problems. Information about their eye health is scarce, particularly for those detained offshore. This is the first study to explore the eye health and services available to this population, helping
