Monitoring glaucoma at home
Glaucoma is a chronic condition that affects cells at the back of the eye. It is the leading cause of irreversible blindness worldwide. People with glaucoma, or at risk of developing glaucoma, require lifelong monitoring, including regular eye tests to track the progression of the disease. A study from City, University of London is the first in the world that suggests glaucoma eye tests can be performed accurately at home by patients themselves. (2020-11-20)

An acebuchin-oil-enriched diet helps to reduce hypertension
The acebuche, also know as the wild olive tree, is a variety of tree widely found throughout Spain and covering almost nine million hectares in Andalusia. However, little data is available on the composition and therapeutic potential of acebuchin oil. The studies mainly focus on the composition and pharmacological effects of olive tree leaves and extra virgin olive oil. (2020-11-17)
