Nonperfused Peripheral Retinal Area in Eyes with Chronic Rhegmatogenous Retinal Detachment

open access: yesCase Reports in Ophthalmology, 2020
We report two cases of chronic rhegmatogenous retinal detachment with a nonperfused peripheral retinal area. Case 1 was an 84-year-old woman who presented with a bullous retinal detachment of the inferior retina and a best-corrected visual acuity of 20 ...

A Novel Deep Learning Pipeline for Retinal Vessel Detection in Fluorescein Angiography [PDF]

open access: yesIEEE Trans. Image Proc., 29(1), 2020, 2019
While recent advances in deep learning have significantly advanced the state of the art for vessel detection in color fundus (CF) images, the success for detecting vessels in fluorescein angiography (FA) has been stymied due to the lack of labeled ground truth datasets.

A Keypoint Detection and Description Network Based on the Vessel Structure for Multi-Modal Retinal Image Registration [PDF]

open access: yesarXiv, 2022
Ophthalmological imaging utilizes different imaging systems, such as color fundus, infrared, fluorescein angiography, optical coherence tomography (OCT) or OCT angiography. Multiple images with different modalities or acquisition times are often analyzed for the diagnosis of retinal diseases.

Generating Fundus Fluorescence Angiography Images from Structure Fundus Images Using Generative Adversarial Networks [PDF]

open access: yesarXiv, 2020
Fluorescein angiography can provide a map of retinal vascular structure and function, which is commonly used in ophthalmology diagnosis, however, this imaging modality may pose risks of harm to the patients. To help physicians reduce the potential risks of diagnosis, an image translation method is adopted.

Multi-modal Retinal Image Registration Using a Keypoint-Based Vessel Structure Aligning Network [PDF]

open access: yesarXiv, 2022
In ophthalmological imaging, multiple imaging systems, such as color fundus, infrared, fluorescein angiography, optical coherence tomography (OCT) or OCT angiography, are often involved to make a diagnosis of retinal disease. Multi-modal retinal registration techniques can assist ophthalmologists by providing a pixel-based comparison of aligned vessel ...

Optical Coherence Tomography-Angiography of a large retinal microaneurysm

open access: yesAmerican Journal of Ophthalmology Case Reports, 2020
A 63-year-old healthy woman was referred for a retinal examination. Dilated fundus examination of the left eye revealed small retinal hemorrhage with surrounding exudation, most consistent with a large retinal microaneurysm, which was confirmed by ...
