By borrowing a tool from bacteria that infect plants, scientists have developed a new approach to eliminate mutated DNA inside mitochondria - the energy factories within cells. Doctors might someday use the approach to treat a variety of mitochondrial diseases, including the degenerative eye disease Leber hereditary optic neuropathy (LHON). The research, published online in Nature Medicine, was f

Foam parties are increasingly popular, but the fun may come with a price. Foam parties may cause eye irritation sufficient to impair vision and require medical treatment, according to a report from the Centers for Disease Control and Prevention (CDC). For example, more than 50 participants in a May 25 foam party at a Naples, Fla., night club sought treatment for eye injuries at local emergency r

A snorkel-shaped device no bigger than a flea is the latest technology offering relief to Clark County residents with glaucoma. The titanium device is only 1 millimeter long and one-third millimeter tall, but it has the potential to make a big difference in the lives of people with mild to moderate glaucoma. The device offers an alternative to traditional methods of treating glaucoma, an alternat

Hyperopia, or farsightedness, is the most common refractive eye error in Asian and non-Hispanic white (NHW) Southern California children overall, but myopia, or nearsightedness, is "relatively more prevalent" among Asian children than hyperopia or astigmatism, according to an article published online August 14 in Ophthalmology. The investigators enrolled 1501 NHW and 1507 Asian children aged 6 to

Eyes are amazing and technical organs, precious to each individual. But how did the human eye develop? According to a review of the evidence, it stems back to fish more than 500 million years ago. Professor Trevor Lamb of The Vision Centre and Australian National University conducted a major scientific review of the origin of the eye, in which he analyzes findings of hundreds of scientists worldw
Handheld Lasers a Public Health Risk
Posted by Praveen (#2) 3943 days ago (Editorial)
Experts predict that, if left unregulated, handheld lasers purchased online could cause an epidemic of ocular injuries. Fernando Arevalo, MD, professor of ophthalmology at the Wilmer Eye Institute, presented a case series of various maculopathies caused by high-powered handheld lasers here at the 31st Annual Meeting of the American Society of Retina Specialists. Fourteen patients, with a mean age
Wavefront Optics-From the Observatory to Your Optometrist's Office
Posted by Praveen (#2) 3943 days ago (Editorial)
Techniques developed by astronomers seeking a clear view of objects in space are coming closer to home, as eye care professionals apply the concept of wavefront optics to understanding-and correcting-subtle visual abnormalities of the human eye, Wavefront optics is beginning to transform the way optometrists and ophthalmologists think about the vision issues they encounter in everyday practice, H
Retinal Ischemia Tied to Variant of Acute Macular Neuroretinopathy
Posted by Praveen (#2) 3943 days ago (Editorial)
Paracentral acute middle maculopathy is a newly identified variant of acute macular neuroretinopathy that appears to result from retinal capillary ischemia, according to a retrospective observational case series. "This has been traditionally a very rare disease but now with advanced retinal imaging systems such as spectral domain optical coherence tomography (SD-OCT). Dr. David Sarraf from the Un
