Seeing Red? Long-term vision problems linked to Viagra

Researchers have found that a high dose of Viagra (sildenafil citrate) can cause retinal damage on a cellular level resulting in color vision problems. Excessive use of the drug could result in long-term vision problems that are potentially irreversible. Study findings were published in the fall issue of Retinal Cases. A study was conducted based […]

Mediterranean Diet Lower Macular Degeneration Risk

People who adhere to the Mediterranean diet (MeDi) are found to have a lower risk of developing age-related macular degeneration (AMD) according to a study published in Ophthalmology. A Mediterranean Diet is one that is rich in fruits, vegetables, legumes and fish. Researchers examined correlations between the incidence of advanced AMD and compliance with the […]

Dangers of red eye relieving eyedrops

Most over-the-counter eyedrops used for treating red eyes, contain tetrahydrozoline which is FDA approved for use in the eyes. Some of the brands that contain the chemical are Visine, Murine Plus and Clarine. The labels specifically state that they are for external use only and to keep them out of the reach of children. However, […]

Google better than experts in diagnosing eye disease

Researcher’s at Google’s DeepMind got together with Moorfields Eye Hospital NHS Foundation Trust to create a new Artificial Intelligence (AI) technique to review eye imaging to make recommendations for care. The team combined two different neural networks with one network analyzing the OCT scan to map the tissue and symptoms of disease it sees and […]

Virtual Reality headset helps AMD patients

With the help of a smartphone, the IrisVision Virtual Reality headset is helping patients who suffer from macular degeneration to be able to enjoy daily tasks. Macular degeneration, causes blurred or no vision in the center of the patient’s visual field making it difficult to distinguish faces, drive and read. The person wears a Virtual […]

No More Eye Injections for Wet Macular Degeneration?

Genetech has formulated Lucentis’ active ingredient into a refillable eye implant that delivers the medication continuously into the eyes of wet macular degeneration patients. Known as the Port Delivery System, the implantable drug has shown promising results in the second phase of clinical studies. The Port Delivery System is slightly bigger than a grain of […]

New genetic markers identified for Glaucoma

Researchers at the QIMR Berghofer Medical Research Institute Statistical Genetic laboratory have identified 40 new genetic markers that increase a person’s risk developing glaucoma. This discovery raises hope that a predictive test for glaucoma will become a reality in the near future. Researchers conducted a genome-wide study of more than 134,000 people with high intraocular […]

Eat an orange a day to keep the AMD away

Oranges are the latest fruit to win accolades for their potential health benefits. The latest study was published in the American Journal of Clinical Nutrition. Researchers at the Westmead Institute for Medical Research were examining the effect flavonoids had on age-related macular degeneration (AMD). More than 2,000 Australian adults aged 50 and over were interviewed […]

Immune cells in retina play a role in vision loss

Australian researchers discovered that a mutation in immune cells (microglia) that exist in the retina prevent cones from developing properly. This discovery is the first time immune cells have been found to play a critical role in the development of cones and gives researchers a better understanding of macular degeneration and other genetic eye diseases.
