A weekly roundup of ophthalmic news from around the web. An Instagram model paid the ultimate price to change her eye color from hazel to light grey. Nadinne Bruna, 32, shelled out $3,000 to have silicone plates implanted in front of her iris, but the procedure ended up costing her much more: 80% of vision in her right eye and 50% in her left eye. Daily Mail Glaucoma expert Thomas W. Samuelson, MD, took the reins this month as the 33rdpresident of the American Society of Cataract and Refractive Surgery (ASCRS). Samuelson is an attending surgeon and founding partner of Minnesota Eye Consultants, and an adjunct professor of ophthalmology at the University of Minnesota. Healio Canadian engineer Marinko Sarunic says his shoebox-sized retinal scanner (shown above) can capture high-resolution, 3-D, cross-sectional images of the tissue in a level of detail that rivals images from much larger scanners. Dr. Eduardo Navajas, a vitreoretinal specialist who tested the device for 8 months, says the scanner eliminates the need for—and the complications from—the injected dye used with fluorescein angiography, the current gold-standard imaging technique. EurekAlert! A genetically modified cornea could help prevent graft rejection, according to a report in the journal Human Gene Therapy. Researchers say a donor cornea engineered to express 2 genes that prevent new blood vessel formation can reduce the risk of tissue rejection in a high-risk rabbit model. The therapy is called OXB-202. EurekAlert! An Indianapolis retirement community recently honored the work of a color-blind artist with late-stage AMD. Ralph Rancourt, 95, began drawing black and white portraits of pets, family members and 20th-century presidents around the time that he was declared legally blind in his left eye. Seven years later, he lost vision in his right eye (also from AMD) and had to pack up his pencils, but his art lives on. Current

I Spy a Stye in Your Eye

Image
Written by Dr. David Evans Last modified on August 6, 2018 What’s that small, red, pimple-like bump on your eyelid that’s causing so much discomfort? It’s probably a stye (sometimes referred to as a sty or hordeolum). Besides being difficult to say 5 times quickly, an eye stye is a type of localized infection that can occur along the base of your eyelashes or underneath your eyelid. Styes that form along the base of the eyelashes are called external styes. They typically occur as a result of an infected eyelash hair follicle and look like the type of pimple that occurs when your pores are clogged with dirt and oil. Styes that form inside the eyelid are called internal styes. Similar to external styes, they are caused by an infection of an oil-producing gland behind the eyelid rather than an eyelash hair follicle. Internal styes result in generalized swelling of the eyelid rather than forming a pimple-like bump. Stye Symptoms As a stye develops, you might begin to experience pain

Post-LASIK Refraction and Pregnancy – Much Ado About Nothing?

Image
Written by Dr. David Evans Last modified on August 23, 2018 During pregnancy, women experience a drastic shift in their hormonal balance that has a ripple effect throughout the body. The spike in hormones like progesterone, estrogen, prolactin, oxytocin and relaxin are all important for a healthy pregnancy, but these increased levels can also impact gastrointestinal processes, blood pressure, skin pigmentation and, you guessed it, ocular health. Due to refractive changes that often occur during pregnancy, most refractive surgeons advise against LASIK during pregnancy, instead suggesting women wait several months after giving birth before considering treatment. Women who have already undergone LASIK may then wonder if the changes in ocular health that can occur during and after pregnancy impact post-LASIK refraction. New research presented by John Kanellopoulos, MD, New York University Medical School, NY, and LaserVision.gr seems to throw cold water on any such concern. The Eyes an
