New therapy could help prolong useful vision and delay total blindness   Millions of Americans are progressively losing their sight as cells in their eyes deteriorate, but a new therapy developed by researchers at the University of California, Berkeley, could help prolong useful vision and delay total blindness.

Study reveals a revolutionary way to treat eye injuries, prevent blindness   New research led by scientists at Newcastle University, UK reveals a potential revolutionary way to treat eye injuries and prevent blindness - by softening the tissue hosting the stem cells which then helps repair wounds, inside the body.         What is Lagophthalmos?   Lagophthalmos is a condition in which the eyelids do not close completely. This prevents complete closure during blinking as well as during sleep.

Preventing Ocular Hypertension   The incidence of ocular hypertension varies among by race and ethnicity, and also increases with age. According to one epidemiological study, African-Caribbean persons are more at risk for ocular hypertension; this group has the highest prevalence of disease globally (12.6%).       What is Keratitis?   Keratitis is a medical term for corneal inflammation. The cornea is a clear dome of epithelium that covers the front of the eye, allowing light to pass through. It covers the iris (colored part of the eye), the pupil and the anterior chamber of the eye.       Alzheimer’s and brain health could soon be detected using an eye exam   Soon, an eye examination may be all that is needed to confirm a diagnosis of Alzheimer's disease, according to researchers at Duke's Health. Duke Eye Center recently recruited and studied the retinas of over 200 individuals to see if there were any differences between those with Alzheimer's and those without.       What is an Aqueous Flare?   An aqueous flare is an optical phenomenon based on light scattering within the anterior chamber of the eye. This phenomenon occurs when an inflamed eye is viewed at right angles to a beam of light shined obliquely into the anterior chamber.       Researchers receive grants to study genetics of contact-lens wearers with and without MK   More than 125 million people worldwide wear contact lenses, and while many are exposed to relatively common bacteria through their contact lenses, not all contract an eye infection.       What is Ametropia?   Ametropia is defined as an eye disorder due to an error in the refractive power of the eye. In simpler words, the eye is unable to bend light correctly and focus images directly on the retina. This ultimately results in blurred vision.       What is Iridodonesis?   Iridodonesis is a condition in which the iris (coloured part of the eye) vibrates during eye movements. Upon moving the eye rapidly, the iris can appear to ‘dance’, or ‘tremble’ (tremulousness).
