Humans and apes do not bare the imprint of nocturnal life in their eye structures

Since the age of dinosaurs, most species of day-active mammals have retained the imprint of nocturnal life in their eye structures. Humans and other anthropoid primates, such as monkeys and apes, are the only groups that deviate from this pattern, according to a new study from The University of Texas at Austin and Midwestern University.

Patients with eye diseases can benefit from ArtCornea

Blindness is often caused by corneal diseases. The established treatment is a corneal transplant, but in many cases this is not possible and donor corneas are often hard to come by. In the future, an artificial cornea could make up for this deficiency and save the vision of those affected.

Esthesiometry may help vision professionals in evaluating dry eyes

A simple test of eyelid sensitivity may help vision professionals in evaluating one of the most common eye-related symptoms: dry eyes. A new study linking increased eyelid sensitivity to decreased function of the eyelid margins is presented in the article - " Lid Margins: Sensitivity, Staining, Meibomian Gland Dysfunction, and Symptoms", appearing in the October issue of Optometry and Vision Science, official journal of the American Academy of Optometry.

Lack of cytokeratin 6A may lead to eye infections

Exposed tissue surfaces, including skin and mucous membranes, are under constant threat of attack by microorganisms in the environment. The layer of cells that line these areas, known as epithelial cells, are the first line of defense against these pathogens, but the underlying molecular mechanisms that allow them to repel microbes are unknown.
