Changes of drusen number and central retinal thickness in age-related macular degeneration patients over two years

Acta Clinica Croatica, 2016
Age-related macular degeneration (ARMD) is the leading cause of blindness in developed world but there are still much unknown facts about the disease itself.

Assistance of Artificial Intelligence in Diagnosis of Vitreoretinal Lymphoma on Optical Coherence Tomography

Advanced Intelligent Systems, Volume 7, Issue 4, April 2025.
The proposed artificial intelligence model, cross‐subject meta‐transfer learning, enables the automatic detection of vitreoretinal lymphoma (VRL) on optical coherence tomography images among 16 retinal diseases and conditions. This study provides an innovative solution to assist in the VRL diagnosis in real‐world clinical implementation, showing ...

Automatic diagnosis of retinal diseases from color retinal images [PDF]

International Journal of Computer Science and Information Security, IJCSIS, Vol. 7, No. 1, pp. 234-238, January 2010, USA, 2010
Teleophthalmology holds a great potential to improve the quality, access, and affordability in health care. For patients, it can reduce the need for travel and provide the access to a superspecialist. Ophthalmology lends itself easily to telemedicine as it is a largely image based diagnosis.

Optic Disc Abnormalities – Diagnosis, Evolution and Influence on Visual Acuity

Biomolecules & Biomedicine, 2010
Congenital abnormalities of the optic disc are not so rare. The etiology for the most of them is unknown. Visual acuity of affected eye may be minimally or severely affected, depending on the extent of lesion. All of these conditions can be unilateral or

Glia Modulates Immune Responses in the Retina Through Distinct MHC Pathways

Glia, Volume 73, Issue 4, Page 822-839, April 2025.
Main Points Glial cells as antigen‐presenting cells are crucial for retinal immune responses during degeneration. Microglia and Müller cells use distinct MHC pathways to modulate T‐cell responses. Several cytokine signaling pathways maintain immune balance.

Automatic Classification of Bright Retinal Lesions via Deep Network Features [PDF]

arXiv, 2017
The diabetic retinopathy is timely diagonalized through color eye fundus images by experienced ophthalmologists, in order to recognize potential retinal features and identify early-blindness cases. In this paper, it is proposed to extract deep features from the last fully-connected layer of, four different, pre-trained convolutional neural networks ...

Anterior ischemic optic neuropathy in association with optic nervehead drusen

Indian Journal of Ophthalmology, 2014
Optic nerve head drusen (ONHD) are incidental ophthalmologic finding in the optic nerve. Patients with ONHD are often asymptomatic, but sometimes present with transient visual obscuration′s (TVO), the reported incidence of which is 8.6%. Optic nerve head

Evaluation of Transfer Learning for Classification of: (1) Diabetic Retinopathy by Digital Fundus Photography and (2) Diabetic Macular Edema, Choroidal Neovascularization and Drusen by Optical Coherence Tomography [PDF]

arXiv, 2019
Deep learning has been successfully applied to a variety of image classification tasks. There has been keen interest to apply deep learning in the medical domain, particularly specialties that heavily utilize imaging, such as ophthalmology. One issue that may hinder application of deep learning to the medical domain is the vast amount of data necessary

An in silico model of retinal cholesterol dynamics (RCD model): insights into the pathophysiology of dry AMD

Journal of Lipid Research, 2017
We developed an in silico mathematical model of retinal cholesterol (Ch) dynamics (RCD) to quantify the physiological rate of Ch turnover in the rod outer segment (ROS), the lipoprotein transport mechanisms by which Ch enters and leaves the outer retina,
