Retinal photodamage

open access: yesJournal of Photochemistry and Photobiology B: Biology, 2001
The retina represents a paradox, in that, while light and oxygen are essential for vision, these conditions also favour the formation of reactive oxygen species leading to photochemical damage to the retina. Such light damage seems to be multi-factorial and is dependent on the photoreactivity of a variety of chromophores (e.g., vitamin A metabolites ...

SegImgNet: Segmentation-Guided Dual-Branch Network for Retinal Disease Diagnoses [PDF]

open access: yesarXiv
Retinal image plays a crucial role in diagnosing various diseases, as retinal structures provide essential diagnostic information. However, effectively capturing structural features while integrating them with contextual information from retinal images remains a challenge.

Performance Evaluation of Retinal OCT Fluid Segmentation, Detection, and Generalization Over Variations of Data Sources

open access: yesIEEE Access
Retinal Optical Coherence Tomography (OCT) is a non-invasive cross-sectional scan of the eye that provides qualitative 3D visualization of the retinal anatomy. It is used to study the retinal structure and the presence of pathogens. The advent of retinal

UrFound: Towards Universal Retinal Foundation Models via Knowledge-Guided Masked Modeling [PDF]

open access: yesarXiv
Retinal foundation models aim to learn generalizable representations from diverse retinal images, facilitating label-efficient model adaptation across various ophthalmic tasks. Despite their success, current retinal foundation models are generally restricted to a single imaging modality, such as Color Fundus Photography (CFP) or Optical Coherence ...

A Unified Model of Spatiotemporal Processing in the Retina [PDF]

open access: yes, 1992
A computational model of visual processing in the vertebrate retina provides a unified explanation of a range of data previously treated by disparate models.
