Cases of an eye infection called Acanthamoeba keratitis have tripled in southeast England since 2011, a new study found. For one in every four of people infected, the disease results in a loss of most of their vision or blindness, the research team said. It’s typically caused by poor contact lens hygiene.
Diabetes management went through a radical
transformation in the last years due to technology: the diabetes patient
community found a strong voice online, continuous glucose monitors are taking
the place of finger pricks, digital patches and insulin pumps make the dosage
of insulin more predictable, and connected devices promise the era of
artificial pancreas real soon. We looked around where diabetes technology
stands today and what could we expect in the next 5-10 years?

Publication date: Available online 25 August 2019Source: Canadian Journal of DiabetesAuthor(s): Sanam Zeib Khan, Nida Ajmal, Rozeena ShaikhAbstractDiabetic Retinopathy (DR) is microvascular complication of retina of eye and regarded as one of the major source of blindness around the globe. It is complex disorder that is characterized by both genetic &environmental factors. Vascular Endothelial Growth Factor (VEGF) gene is one of the main candidate gene for DR; also it is involved in several diseases such as microvascular complications of DM and cancer. The VEGF gene is extremely polymorphic. The 18bp fragment (I/D) pol…
When most people think about sun-related damage, they probably worry about their skin. But the sun’s ultraviolet rays also pose a threat to a person’s eyes.
According to a 2014 study funded by the U.S. National Eye Institute, part of the National Institutes of Health, UV radiation can damage proteins in the eye’s lens. Over time, this damage can raise a person’s risk for cataracts, which impair vision.
“When you don’t wear protection, ultraviolet radiation you cannot see is penetrating the eye, and the eye structures are very sensitive to it,” says Dr. Rebecca Taylor, a Nashville-b…
CONCLUSION: Using church-based volunteers and ophthalmic nurses during community screening proved efficient in the identification and referral of pediatric cataract. Keeping regular identification activities in the community and maintaining high-quality and accessible pediatric cataract surgery services can help to clear up the backlog of cataract blind children.
CONCLUSION: The blindness prevalence is high, and the major causes are avoidable in the health zone. The findings suggest that investments in the program over the last 10 years might have led to almost a halving in the prevalence of blindness in th e population. However, the small sample size of persons 50+ years from Wurno zone in the 2005 survey necessitate caution when comparing the 2005 and the 2016 surveys.

Pathogenic Acanthamoeba spp. cause granulomatous amoebic encephalitis and keratitis. Acanthamoeba keratitis (AK) is a rare but serious ocular infection that can result in permanent visual impairment or blindness. However, pathogenic factors of AK remain unclear and treatment for AK is arduous. Expression levels of proteins secreted into extracellular space were compared between A. castellanii pathogenic (ACP) and non-pathogenic strains. Two-dimensional polyacrylamide gel electrophoresis revealed 123 differentially expressed proteins, including 34 increas…
(University College London) A new outbreak of a rare but preventable eye infection that can cause blindness, has been identified in contact lens wearers in a new study led by UCL and Moorfields Eye Hospital researchers.The research team found a threefold increase in Acanthamoeba keratitis since 2011 in South-East England.

Pathogenic Acanthamoeba species often cause infection known as Acanthamoeba keratitis among people who use contact lenses. It is a type of infection that can result in corneal ulceration, visual loss or even blindness, if not treated. There are various therapeutic options available in the treatment of Acanthamoeba infections but they are usually tough treatments with limited efficacy. For instance, hydrogen peroxide (H2O2) is a commonly used contact …
Acanthamoeba spp. is a free living protozoan in the environment, but can cause serious diseases. Acanthamoeba keratitis (AK), a severe and painful eye infection, must be treated as soon as possible to prevent ulceration of the cornea, loss of visual acuity, and eventually blindness or enucleation. Although the disease affects principally contact lens (CLs) wearers, it is recognized nowadays as a cause of keratitis also in non-CLs wearers. Although the number of infections caused by these amoebae is low, AK is an emerging disease presenting an extended number of cases each year worldwide mostly due to the increasing use of …

Acanthamoeba species are free living amoeba found widely all over the world. They are responsible for Acanthamoeba keratitis (AK), an infection which is especially seen in contact lens users and after minor corneal traumas, that may lead blindness. At present, antifungals and antiseptics are used for the treatment of AK cases, however, some problems such as long treatment periods and the occurrence of side effects, resistance of cyst forms against drugs, emphasize the need for new drugs. There are some published studies tha…
