New research reveals an alarming, self-acknowledged gap in family doctors’ skills when it comes to diagnosing and treating patient’s eye conditions.
Myopia-related differences in eye structure may help in developing ‘customized’ intraocular lenses
The presence of myopia, or nearsightedness, significantly affects the muscles used in focusing the lens of the eye-a finding with important implications for the development of “accommodating”…
UTA physicists devise gene therapy platform for macular degeneration patients
Millions of adults over age 50 struggle each year with vision loss caused by damage to the retina or common macular degeneration.This is a photograph of a laser gene delivery system.

A survey of patients with glaucoma in Washington, D.C., showed that the perception of the legality and acceptability of marijuana use was significantly associated with intentions to use marijuana…
Eyes turn into skin: How inflammation can change the fate of cells
EPFL scientists have found that chronic inflammation can cause regenerating cells to grow into new, aberrant types; this is called metaplasia, and is a disorder linked to prolonged inflammation.
