Acta Ophthalmologica, EarlyView.Abstract Purpose To evaluate choroidal changes in high myopic (HM) patients with posterior staphyloma (PS) and explore their association with Gaussian curvature (K) using ultra‐wide‐field optical coherence tomography angiography (UWF‐OCTA). Methods HM patients with wide macular PS (Type I PS) and without any PS (control) were recruited.

Choriocapillaris Flow Signal Impairment in Sorsby Fundus Dystrophy [PDF]
arXiv, 2021 Purpose: To quantify choriocapillaris flow alterations in early Sorsby Fundus Dystrophy (SFD) and to investigate the relationship of choriocapillaris flow with the choroidal and outer retinal microstructure. Methods: In this prospective case-control study, 18 eyes of 11 patients with early SFD and 32 eyes of 32 controls without ocular pathology ...

Investigative Ophthalmology and Visual Science, 2016 Purpose Drusenoid pigment epithelial detachments (PEDs) are a defined path to atrophy in age-related macular degeneration (AMD). We analyzed the relationships between retinal pigment epithelium (RPE) and drusen volume changes during the PED lifecycle ...

Multi-Scale Convolutional Neural Network for Automated AMD Classification using Retinal OCT Images [PDF]
arXiv, 2021 Age-related macular degeneration (AMD) is the most common cause of blindness in developed countries, especially in people over 60 years of age. The workload of specialists and the healthcare system in this field has increased in recent years mainly due to the prevalence of population aging worldwide and the chronic nature of AMD. Recent developments in

U-Net with spatial pyramid pooling for drusen segmentation in optical coherence tomography [PDF]
arXiv, 2019 The presence of drusen is the main hallmark of early/intermediate age-related macular degeneration (AMD). Therefore, automated drusen segmentation is an important step in image-guided management of AMD. There are two common approaches to drusen segmentation. In the first, the drusen are segmented directly as a binary classification task.
