Closed-chamber haptic re-externalisation for posteriorly displaced sclerotomy and inadequate haptic tuck in glued posterior chamber intraocular lenses

This technique (online video http://jcrsjournal.org) emphasises the importance of both symmetrical and sufficient anterior placement of sclerotomies to externalise an adequate length of the haptics, which in turn provides good centration and stability of the intra-ocular lens (IOL). The authors...

Exposure to atomic bomb radiation and age-related macular degeneration in later life

This paper is one of the outcomes of the Adult Health Study; a cohort study of the atomic bomb survivors of Hiroshima-Nagasaki in Japan. It investigates the proposed association between pasty radiation exposure early in life and the presence of...

Is an increased homocysteine level associated with greater risk of AMD?

Basic research studies have implicated homocysteine in causing vascular endothelial dysfunction and inflammation, and this has been borne out in large observational studies which suggested that elevated homocysteine is associated with increased risk of cardiovascular disease. In order to determine...

ABCA1 mediates lipid efflux in the retina

Age-related macular degeneration (AMD) is the leading cause of blindness in the elderly population. There are two forms of AMD, dry and wet, the latter so named because of the presence of choroidal neovascularisation. Both forms lead to retinal pigment...

The long-term effects of AREDS on AMD progression

The Age-Related Eye Disease Study (AREDS) was an 11-centre, double-masked, clinical trial that in 2001 found a high-dose of antioxidant vitamins plus zinc was effective in protecting against progression of age-related macular degeneration (AMD) in patients with moderate to high...

Macular pigment in relatives of AMD patients

Blue light causes photo-oxidative retinal injury and macular pigment (MP), with lutein, zeaxanthin and mesozeaxanthin as the main components, as a filter that protects the macula from this damage. Previous studies indicated that low levels of macular pigment optical density...

CD40L activation of human RPE cells

Age-related macular degeneration (AMD) is the leading cause of reduced visual acuity in the elderly worldwide. The risk factors involved in AMD include smoking and diet, while genetics have been shown to have a significant role. Recently a link between...
