Review: Myopia
Source: Lancet
Area: News
This review article looks at the biological basis, epidemiology, causes, environmental and genetic risk factors, and ocular morbidity of myopia, and interventions (including pharmacological) to control the disease. The authors note that myopia has emerged as a major health issue in east Asia (prevalence of 80-90% in school-leavers); this high prevalence seems to be associated with increasing educational pressures, combined with life-style changes, which have reduced the time children spend outside. Similar, but less marked, changes are occurring in other parts of the world. There are promising optical and pharmacological interventions for preventing the development of myopia or slowing its progression, which require further validation, and promising vision-sparing treatments for pathological myopia.

Review: Age-related macular degeneration
Source: Lancet
Area: News
This review article looks at the epidemiology, genetics and pathogenesis, clinical features and classification, prevention and treatment of age-related macular degeneration (AMD), a major cause of blindness worldwide. Treatments reviewed include laser photocoagulation, photodynamic therapy (PDT), anti-VEGF therapy (pegaptanib, ranibizumab, bevacizumab, aflibercept). Finally the authors discuss new research in the treatment of this disease, and its possible implications.

Large study of male physicians suggests vitamin C and E supplementation unlikely to have a significant effect on early AMD
Source: Ophthalmology
Area: News
According to research published early online in, supplementation with high-dose vitamin E and vitamin C, alone or in combination, is unlikely to have a beneficial effect on the incidence of early AMD. The authors note that the Age-Related Eye Disease Study (AREDS) showed that daily supplementation with zinc and a high-dose antioxidant combination (vitamin E, vitamin C, and beta carotene) could reduce the risk of advanced AMD by 25% in persons with intermediate AMD or advanced AMD in one eye. The study was not however sufficiently powered to determine whether the combination could delay the onset or progression of early AMD. They discuss data published so far in this area, which have failed to show any benefits of vitamin E or beta carotene. Gaps in the data however remain. In this report, they present the final results for AMD from the vitamin E and vitamin C components of the Physician's Health Study II (PHS II). PHS II is an ...

Bionic eye helps two blind men see for the first time in 20 years
In a medical breakthrough two blind men have regained partial sight for the first time in more than 20 years after receiving a “bionic eye”. Scientists said the first clinical trials of the microchip eye implant, which measures just 3mm across and is fitted behind the eyeball, have proved successful and “exceeded expectations”.
