Space flight may be bad for your eyesight. Changes found in astronauts' eye tissue may cause vision problems, and possibly even blindness. As well as threatening the health of astronauts, this could jeopardize long-haul missions into space. 27 NASA astronauts after they had spent an average of 108 days in space. Four had bulging of the optic nerve, three had kinks in the nerve sheath, and six had

Posted by Bharat (#1) 4534 days ago (Editorial)
Wii remotes are not all about fun and games. Scientists can use them to assess and diagnose children with an abnormal head position caused by eye diseases. As described in a recent Investigative Ophthalmology & Visual Science article, researchers developed a low-cost digital head posture measuring device with Nintendo Wiimotes to help diagnose this condition, medically called ocular torticollis.

Iontophoresis, a technique long known but never successfully used for ocular drug delivery, has been shown to be a safe and effective method for the delivery of dexamethasone to the eye using the power of an electric field, according to data presented here at the World Ophthalmology Congress 2012.In this study, a small electrical charge was used to introduce high concentrations of charged dexamet
How A Bacterial Pathogen Breaks Down Barriers To Enter And Infect Cells
Posted by Bharat (#1) 4536 days ago (Editorial)
Scientists from the Schepens Eye Research Institute, a subsidiary of Mass. Eye and Ear and affiliate of Harvard Medical School, have found for the first time that a bacterial pathogen can literally mow down protective molecules, known as mucins, on mucus membranes to enter and infect a part of the body. Their landmark study, published in PLoS ONE, describes how they discovered that an "epidemic"
Eye Movement Not Engaged in 'Arms Race'
Posted by Bharat (#1) 4536 days ago (Editorial)
We make our eye movements earlier or later in order to coordinate with movements of our arms, New York University neuroscientists have found. Their study, which appears in the journal Neuron, points to a mechanism in the brain that allows for this coordination and may have implications for rehabilitation and prosthetics.To see more details visit,
