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.

Deep Angiogram: Trivializing Retinal Vessel Segmentation [PDF]
In Medical Imaging 2023: Image Processing, vol. 12464, pp.
656-660. SPIE, 2023, 2023 Among the research efforts to segment the retinal vasculature from fundus images, deep learning models consistently achieve superior performance. However, this data-driven approach is very sensitive to domain shifts. For fundus images, such data distribution changes can easily be caused by variations in illumination conditions as well as the presence ...

Vascularized drusen: a cross-sectional study
International Journal of Retina and Vitreous, 2019 Background To investigate whether neovascularization may arise and be detectable in drusen, as reported in histopathologic studies, by OCTA prior to developing exudation and to assess its prevalence in a cohort of patients with intermediate AMD.

Druse-Induced Morphology Evolution in Retinal Pigment Epithelium [PDF]
arXiv, 2016 The retinal pigment epithelium (RPE) is a key site of pathogenesis for many retina diseases. The formation of drusen in the retina is characteristic of retinal degeneration. We investigate morphological changes in the RPE in the presence of soft drusen using an integrated experimental and modeling approach. We collect RPE flat mount images from donated

Eye Disease Prediction using Ensemble Learning and Attention on OCT Scans [PDF]
arXiv, 2023 Eye diseases have posed significant challenges for decades, but advancements in technology have opened new avenues for their detection and treatment. Machine learning and deep learning algorithms have become instrumental in this domain, particularly when combined with Optical Coherent Technology (OCT) imaging.

POSSIBILITIES OF MODERN IMAGING TECHNIQUES IN DIAGNOSTICS OF OPTIC NERVE DRUSEN (LITERATURE REVIEW)
Acta Biomedica Scientifica, 2016 With the introduction and development of new diagnostic techniques, the relevance of drusen of the optic nerve diagnostics is increasing. Existing imaging techniques alone or in their various combinations cannot allow to confirm optic nerve drusen in all
