Corrigendum to “Zeaxanthin: Review of Toxicological Data and Acceptable Daily Intake”

Journal of Ophthalmology, Volume 2019, Issue 1, 2019., 2019
Zeaxanthin is a nutritional carotenoid with a considerable amount of safety data based on regulatory studies, which forms the basis of its safety evaluation. Subchronic OECD guideline studies with mice and rats receiving beadlet formulations of high‐purity synthetic zeaxanthin in the diet at dosages up to 1000 mg/kg body weight (bw)/day, and in dogs at

Макуларна ретиношиза и нејзината семиотска важност [PDF]

, 2015
Вовед. Поимот ретиношиза означува раздвојување во слоевите на неуроретината. Може да се случи во периферните делови на ретината, но исто така и во регионот на макула лутеа кога зборуваме за макуларна ретиношиза.

Omega 3 fatty acids for preventing or slowing the progression of age-related macular degeneration. [PDF]

, 2015
BACKGROUND: Evidence from animal models and observational studies in humans has suggested that there is an inverse relationship between dietary intake of omega 3 long-chain polyunsaturated fatty acids (LCPUFA) and risk of developing age-related macular ...

A Fast and Effective Method of Macula Automatic Detection for Retina Images [PDF]

arXiv, 2020
Retina image processing is one of the crucial and popular topics of medical image processing. The macula fovea is responsible for sharp central vision, which is necessary for human behaviors where visual detail is of primary importance, such as reading, writing, driving, etc.

Recent developments in the use of nanocrystals to improve bioavailability of APIs

WIREs Nanomedicine and Nanobiotechnology, Volume 16, Issue 2, March/April 2024.
Formulation and Adminstration of Nanocrystals. Abstract Nanocrystals refer to materials with at least one dimension smaller than 100 nm, composing of atoms arranged in single crystals or polycrystals. Nanocrystals have significant research value as they offer unique advantages over conventional pharmaceutical formulations, such as high bioavailability,

Clinical Analysis of 42 Cases of Ocular Ischemic Syndrome

Journal of Ophthalmology, Volume 2018, Issue 1, 2018., 2018
Ocular ischemic syndrome (OIS) is a severe ocular disease caused by ocular hypoperfusion due to stenosis or occlusion of the common or internal carotid arteries. OIS is easily misdiagnosed or undiagnosed given its asymptomatic onset and complicated ocular manifestations.

Direct discrimination of structured light by humans [PDF]

, 2019
We predict and experimentally verify an entoptic phenomenon through which humans are able to perceive and discriminate structured light with space-varying polarization. Direct perception and discrimination is possible through the observation of distinct profiles induced by the interaction between the polarization gradients in a uniform-intensity beam ...

Analysis of Macula on Color Fundus Images Using Heightmap Reconstruction Through Deep Learning [PDF]

arXiv, 2020
For medical diagnosis based on retinal images, a clear understanding of 3D structure is often required but due to the 2D nature of images captured, we cannot infer that information. However, by utilizing 3D reconstruction methods, we can recover the height information of the macula area on a fundus image which can be helpful for diagnosis and screening
