A recent retrospective study by four Michigan physicians shows strong evidence that symptoms of headache, dizziness and anxiety in some patients with traumatic brain injury potentially could be alleviated or even eliminated with specialized eyeglass lenses containing prisms. The paper was published in the April 2010 issue of Physical Medicine and Rehabilitation. The study suggests that TBI appears to be causing visual image misalignment – or vertical heterophoria.

A new predictor of cornea transplant success has been identified by the Cornea Donor Study (CDS) Investigator Group. New analysis of data from the 2008 Specular Microscopy Ancillary Study, found that the preoperative donor cell count of endothelial cells, did not correlate with graft success. Instead the study found that a patient’s endothelial cell count six months post-cornea transplant is a better indicator of subsequent failure of the graft rather than the donor’s cell count.

During the 5th International Congress of Corneal Cross Linking for Keratoconus in Germany, Avedro presented encouraging clinical results for treating keratoconus, a progressive disease of the cornea of the eye. The procedure, known as Keraflex® KXL, is non-incisional and reshapes the cornea without removing any tissue. Keratoconus, or KC, is a cone-shaped protrusion and distortion of the cornea that typically begins in the teenage years or 20’s and afflicts millions of people around the world.

Use of hydrogen peroxide solution was associated with the lowest incidence of corneal infiltration among daily hydrogel contact lens wearers, according to a study published in Arch Ophthalmol. The study included 558 patients with myopia who participated in one or more of about 40 trials for 20 hydrogel contact lens and lens solution combinations. Patient assessments were conducted at baseline, 2 weeks, 1 month and 3 months. Data included 840 lens-solution combinations and 2,271 participant-months.

Researchers at Aston University, UK have been awarded over £1 million pounds worth of funding from the BBSRC and the EPSRC to investigate the fundamental processes involved in human vision. The BBSRC project will see the Aston research team conduct psychophysical experiments to study the binocular perception and performance of human observers in order to develop a more complete theory and understanding of binocular spatial vision through successive refinements of a computational model.
