Blue Light Exposure: Ocular Hazards and Prevention-A Narrative Review.

Introduction: Exposure to blue light has seriously increased in our environment since the arrival of light emitting diodes (LEDs) and, in recent years, the proliferation of digital devices rich in blue light. This raises some questions about its potential deleterious effects on eye health. The aim of this narrative review is to provide an update on the ocular effects of blue light and to discuss the efficiency of methods of protection and prevention against potential blue light-induced ocular injury.

Mitochondrial Dysfunction and Endoplasmic Reticulum Stress in Age Related Macular Degeneration, Role in Pathophysiology, and Possible New Therapeutic Strategies.

Age related macular degeneration (AMD) is the main cause of legal blindness in developed countries. It is a multifactorial disease in which a combination of genetic and environmental factors contributes to increased risk of developing this vision-incapacitating condition. Oxidative stress plays a central role in the pathophysiology of AMD and recent publications have highlighted the importance of mitochondrial dysfunction and endoplasmic reticulum stress in this disease.

Vitamin D and Age-Related Macular Degeneration.

In recent years, the relationship between vitamin D and health has received growing attention from the scientific and medical communities. Vitamin D deficiencies have been repeatedly associated with various acute and chronic diseases, including age-related macular degeneration (AMD). Its active metabolite, 1α,25-dihydoxy vitamin D, acts as a modulator of cell proliferation, differentiation and apoptosis, and cumulative data from experimental and observational studies suggest that relatively a lower vitamin D status could be a potential risk factor for the development of early and/or late AMD.

Optimization of 100 μm alginate-poly-L-lysine-alginate capsules for intravitreous administration.

The field of cell microencapsulation is advancing rapidly. Particle size plays a critical role in terms of biocompatibility and limits decisively its applicability. Producing reduced size microcapsules involves broadening the possibilities to employ this technology in the treatment of many disorders.

Lack of association between polymorphisms in C4b-binding protein and atypical haemolytic uraemic syndrome in the Spanish population.

Dysregulation of the alternative pathway of complement activation, caused by mutations or polymorphisms in the genes encoding factor H, membrane co-factor protein, factor I or factor B, is associated strongly with predisposition to atypical haemolytic uraemic syndrome (aHUS). C4b-binding protein (C4BP), a major regulator of the classical pathway of complement activation, also has capacity to regulate the alternative pathway. Interestingly, the C4BP polymorphism p.

[Survey of the necessary follow-up examinations after uncomplicated phacoemulsification surgery].

Objective: To evaluate which the minimum number of postoperative examinations after uncomplicated phacoemulsification cataract surgery is needed to assure an appropriate follow-up schedule. We evaluated the number of patients that were excluded from the postoperative follow-up schedule and their causes.

Methods: A prospective study was performed on 120 eyes (106 patients), that were randomised in two groups: one with two follow-up visits (first day and one month) and another with three postoperative visits (first day, one week and one month).

Intravitreal and subretinal proliferation induced by platelet-rich plasma injection in rabbits.

We developed an experimental model of proliferative vitreoretinopathy (PVR) in albino rabbits by combining some factors suspected of causing the disease. Sixty nine eyes divided into six groups served as controls (Groups C 1-6). Forty nine eyes were divided into four experimental groups (Groups E 1-4).
