Two Therapies Shown to Treat Retinopathy Progression
Two cardiovascular therapies may slow the progression of diabetic retinopathy in high-risk adults with type 2 diabetes, according to the Action to Control Cardiovascular Risk in Diabetes (ACCORD) Eye Study, supported by the National Institutes of Health.
Of the 10,251 participants in the ACCORD study, 2,856 participants — all adults with type 2 diabetes at high risk for heart attack, stroke or cardiovascular death — were included in the ACCORD Eye Study. Researchers compared three intensive treatments to standard treatments for lowering cardiovascular risks and analyzed how those treatments affected diabetic retinopathy progression over 4 years.
Intensive versus standard blood pressure control measures had no impact on diabetic retinopathy. However, intensive measures for blood sugar control and lipid therapy (combination fibrate and statin) reduced the progression of diabetic retinopathy compared with standard measures. The full study has been published in the New England Journal of Medicine.

SCCO Students Hone Toric Fitting Skills at Industry-Supported Workshop
Eighty-six third-year students at Southern California College of Optometry (SCCO) gained valuable hands-on fitting, prescribing and communication experience at Industry Toric Workshops held there this summer.
"This workshop is a phenomenal opportunity for the students to learn hands-on skills in fitting soft toric contact lenses," said SCCO Associate Professor Harue J. Marsden, OD, M.S. "More importantly, in one evening they have the opportunity to fit lenses from various manufacturers and learn the nuances of various products. This is an extraordinary collaboration of industry partners and education that benefits student learning and patient care."
The workshops were developed by Teague Training Group of Huntington Beach, Calif., and supported by Bausch + Lomb and founding sponsors CIBA Vision Corporation and Vistakon, a division of Johnson & Johnson Vision Care Inc.

Practitioners Not Gaga for Lenses
The American Academy of Ophthalmology is calling the decorative "circle lenses," contact lenses popularized by Lady Gaga in a recent video, "an emerging and potentially dangerous trend among teenagers and young adults." In particular, the organization is concerned that the lenses are available online and in stores without a prescription, exam or fitting. It warns, "Inflammation and pain can occur from improperly fitted, over-the-counter lenses, leading to more serious problems including corneal abrasions and blinding infections."

Depression Dulls Contrast Sensitivity
People with depression often use terms such as "gray mood" to describe their feelings and experiences. To objectively assess how patients with depression see the world, researchers tested visual contrast perception with a pattern electroretinogram in 40 healthy control subjects, as well as 20 medicated and 20 unmedicated patients with depression.
Retinal contrast gain was dramatically lower among depressed patients with and without medication, compared to patients without depression.
