Attention-Aided Generative Learning for Multi-Scale Multi-Modal Fundus Image Translation

IEEE Access, 2023
Conventional fundus images (CFIs) and ultra-widefield fundus images (UFIs) are two fundamental image modalities in ophthalmology. While CFIs provide a detailed view of the optic nerve head and the posterior pole of an eye, their clinical use is ...

The Future of Nanomaterials Tackling the Challenge of Delivering Nucleic Acids to the Retina

Advanced Functional Materials, Volume 35, Issue 3, January 15, 2025.
Gene therapy is often the only hope for a cure for many retinal diseases. However, due to the unique anatomy of the eye, the introduction of such genes or nucleic acids is extremely challenging. This article presents various diseases, barriers, and challenges as well as methods and different nanomaterials that are used to deliver nucleic acids into the

Multicolor imaging in optic disc swelling

Indian Journal of Ophthalmology, 2017
Differentiating optic disc edema (ODE) from pseudo optic disc edema (PODE) continues to pose a diagnostic dilemma. Current report highlights the role of multicolor imaging (MC) in differentiating ODE from PODE.

Retinal pigment epithelium degeneration caused by aggregation of PRPF31 and the role of HSP70 family of proteins [PDF]

, 2020
Background Mutations in pre-mRNA splicing factor PRPF31 can lead to retinitis pigmentosa (RP). Although the exact disease mechanism remains unknown, it has been hypothesized that haploinsufficiency might be involved in the ...

Identifying the retinal layers from optical coherence tomography images using a 3D segmentation method

IET Image Processing, Volume 19, Issue 1, January/December 2025.
The paper proposes a novel automated method of retinal layer segmentation from spectral domain optical coherence tomography images in 3‐dimensional (3D) space. 3D segmentation utilizes more information than 2D segmentation and therefore leads to more accurate and reliable segmentation than 2D segmentation. This automated method performance demonstrates

Bilateral Optic Disc Drusen with Neuroretinitis [PDF]

, 2022
Background: Neuroretinitis is an inflammation of the posterior pole of the eye, resulting in optic disc edema and macular star formation. Systemic conditions associated with these findings include tuberculosis, toxoplasmosis, syphilis, lyme disease ...

Paramagnetic rim lesions are associated with inner retinal layer thinning and progression independent of relapse activity in multiple sclerosis

European Journal of Neurology, Volume 32, Issue 1, January 2025.
Abstract Background and purpose Paramagnetic rim lesions (PRLs) are chronic active lesions associated with a severe disease course in multiple sclerosis (MS). This study was undertaken to investigate an association between retinal layer thinning (annualized loss of peripapillary retinal nerve fiber layer [aLpRNFL] and ganglion cell–inner plexiform ...

Artificial Intelligence-Based ChatGPT Responses for Patient Questions on Optic Disc Drusen

Ophthalmology and Therapy, 2023
Introduction Optic disc drusen (ODD) are acellular deposits in the optic nerve head, which are most often benign and asymptomatic. Patients may develop visual field defects and be at increased risk of ischemic co-morbidities.
