Automatic lesion segmentation and Pathological Myopia classification in fundus images [PDF]

arXiv, 2020
In this paper we present algorithms to diagnosis Pathological Myopia (PM) and detection of retinal structures and lesions such asOptic Disc (OD), Fovea, Atrophy and Detachment. All these tasks were performed in fundus imaging from PM patients and they are requirements to participate in the Pathologic Myopia Challenge (PALM). The challenge was organized

Myopia prediction for adolescents via time-aware deep learning [PDF]

arXiv, 2022
Background: Quantitative prediction of the adolescents' spherical equivalent based on their variable-length historical vision records. Methods: From October 2019 to March 2022, we examined binocular uncorrected visual acuity, axial length, corneal curvature, and axial of 75,172 eyes from 37,586 adolescents aged 6-20 years in Chengdu, China.

Aqueous humour concentrations of HB‐EGF, EGF and VEGF‐A and axial length in humans

Acta Ophthalmologica, EarlyView.
Abstract Purpose To investigate relationships between the intraocular concentrations of heparin‐binding epidermal growth factor (HB‐EGF), epidermal growth factor (EGF) and vascular endothelial growth factor A (VEGF‐A) in dependence on axial length in humans. Design Clinical interventional cohort study.

Morphological changes of sclera in rats with experimental myopia [PDF]

Морфологія, 2014
Background. The absence of adequate experimental myopia model is the actual problem in pathophysiological studying of the myopia progression. Studies of the chick eye have formed the basis for several hypotheses of myopic development.

On the moduli space of ricci flat metrics on a K3 surface [PDF]

arXiv, 2020
We show that the moduli space of Ricci flat metrics of unit volume (including orbifold metrics) on a K3 surface is simply connected and that it has the same rational cohomology as the automorphism group of the K3 lattice $(-E_8)^{\oplus 2}\oplus U^{\oplus 3}$.

Depth-multiplexing spectral domain OCT for full eye length imaging with a single modulation unit [PDF]

arXiv, 2023
Measuring the axial length of the eye is emerging as a crucial approach to measure progression and monitor management of myopia. The high cost of current swept-source OCT devices, the preferred method for such measurements, limits their broad use, especially in lower-income communities.While spectral domain (SD) OCT is a more affordable option, its ...

Comparative efficacy of intravitreal anti‐VEGF therapy for neovascular age‐related macular degeneration: A systematic review with network meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract The aim of this review was to evaluate the comparative efficacy of intravitreal anti‐vascular endothelial growth factor (anti‐VEGF) therapy for neovascular AMD. We searched 12 literature databases for randomised clinical trials (RCT) on anti‐VEGF therapy for neovascular AMD and extracted data on: change from baseline to 12 months in best ...

Outcome and safety of multiple photodynamic therapy sessions in chronic central serous chorioretinopathy

Acta Ophthalmologica, EarlyView.
Abstract Purpose This study evaluates the effectiveness and safety of multiple PDT sessions for cases of persistent and recurrent subretinal fluid (SRF) in chronic central serous chorioretinopathy (CSC). Methods This multicentre, retrospective cohort study included patients aged ≥18 years with chronic CSC who received at least two sessions of PDT at ...

Alteraciones del polo posterior en la miopía degenerativa Alterations of the posterior pole in degenerative myopia patients

Revista Cubana de Oftalmología, 2012
La miopía degenerativa constituye una de las causas fundamentales de pérdida de la visión. Esto está relacionado con las alteraciones del polo posterior, que afectan la retina neurosensorial, el epitelio pigmentario de la retina y las capas más internas ...

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.
