Sjogren's Syndrome Test
"Nicox (Sophia Antipolis, France) has gained exclusive U.S. rights to a lab test targeted at early detection and diagnosis of Sjogren's syndrome. Nicox will be responsible for all marketing activities, while test developer Immco will carry out the test in its CLIA-approved laboratory in Buffalo, N.Y., and be responsible for regulatory activities and reimbursement, Nicox said in a press release. Nicox also has a nine-month option to negotiate an agreement to promote the test in the rest of the world. The test is based on the discovery of novel antibodies in Sjogren's syndrome: SP-1 (salivary
gland protein-1), CA-6 (carbonic anhydrase-6), and PSP (parotid secretory protein). Traditional tests use ANA, Ro, La and RF antibodies that are associated with later-stage disease, Nicox said. The novel antibodies were found in 45% of patients meeting the criteria for Sjogren's syndrome who lacked the traditional antibodies for Ro or La. In patients diagnosed with idiopathic xerostomia and
xerophthalmia for less than two years, 76% had antibodies to SP-1 and/or CA-6 while only 31% had antibodies to Ro or La." (This quote was from the June 21,2013 issue of EyeWorld Weely Update.)
Increased Costs of Vision Related Diseases
Prevent Blindness America has issued a report that the "total economic burden of eye disorders and vision loss in the United States this year" will be $139 Billion. This is far greater than previous data had indicated." A breakdown of estimated costs of eye disorders and vision loss from the perspective of three payers: government ($47.4 billion), private insurance ($20.8 billion in direct
medical costs and $1.3 billion for long term care) and patients and their families ($71.6 billion)." To view the full report, please click here.
New Corneal Layer Reported
In an article in press of the journal Ophthalmology, a new corneal layer is reported on and referred to as "Dua's Layer" in recognition of Dr. Harminder Dua, the lead researcher of the study group at the University of Nottingham that submitted the paper. They report a distinct layer that occurs between the corneal stroma and Descemet's membrane (making it the fourth layer from the
front). This layer is acellular, measuring only 15µ thick (0.00059 inches) and "despite its thinness, the layer is very strong and impervious to air." It is composed of 5 to 8 lamellae of predominantly type-1 collagen bundles arranged in transverse, longitudinal, and oblique directions. The
researchers indicate their finding will have considerable impact on posterior corneal surgery possibly helping improve outcomes for corneal graft and implants specifically as well as advance the understanding of corneal biomechanics and posterior corneal pathology such as acute hydrops, Descematocele and pre-Descemet's dystrophies.

Contact Lens Gives Telescopic Vision
Mark Ward, Technology correspondent at BBC News reported that "Researchers have created contact lenses which, when paired with special spectacles, bestow telescopic vision on their wearers. The contact-lens-and-spectacles combination magnifies scene details by 2.8 times. Polarizing filters in the spectacles allow wearers to switch between normal and telescopic vision. The telescopic sight system has been developed to help people suffering age-related blindness.
Age-related macular degeneration is one of the most common forms of blindness and damages the part of the eye, the macula, that handles fine detail. As this area degenerates, sufferers lose the ability to recognize faces and perform tasks, such as driving and reading, that rely on picking up details."
"The contact lens created by the researchers has a central region that lets light through for normal vision. The telescopic element sits in a ring around this central region. Tiny aluminum mirrors scored with a specific pattern act as a magnifier as they bounce the light around four times within
the ring before directing it towards the retina. In ordinary use, the magnified image is not seen as it is blocked by polarizing filters set in a companion pair of spectacles. Wearers can switch it on by changing the filters on the spectacles so the only light falling on their retina comes from the magnified stream.
For their filtering system, the researchers, led by Joseph Ford at UC San Diego and Eric Tremblay at Switzerland's EPFL, adapted a pair of glasses that Samsung produces for some of its 3D TV sets. In normal use, these spectacles create a 3D effect by alternately blocking the right or left lens. The prototype contact lens produced by the team is 8mm in diameter, 1mm thick at its centre and
1.17mm thick in its magnifying ring. "The most difficult part of the project was making the lens breathable," Dr Tremblay told the BBC. "If you want to wear the lens for more
than 30 minutes you need to make it breathable."
"The contact lenses might find a role on the battlefield to help soldiers.
Gases have to be able to penetrate the lens to keep the parts of the eye covered by the contact, especially the cornea, supplied with oxygen," he said. The team has solved this problem by
producing lenses riddled with tiny channels that let oxygen flow through. However, said Dr
Tremblay, this made manufacturing the lenses much more difficult. "The fabrication tolerances are quite challenging because everything has to be so precise."
"Despite this, gas-permeable versions of the telescopic lens are being prepared that will be used in clinical trials in November, he said. Eventually it should be possible for those with age-related sight problems to wear the telescopic lenses all day. The lenses are an improvement on other ways these sight problems have been tackled which has included surgery to implant a telescopic lens or
wearing bulky spectacles that have telescopic lenses forming part of the main lens.
"Clara Eaglen, eye health campaigns manager at the RNIB said the research looked "interesting" and praised its focus on macular degeneration. "It is encouraging that innovative products such as these telescopic contact lenses are being developed, especially as they aim to make the most of a person's existing vision," she said. ""Anything that helps to maximize functioning vision is very important as this helps people with sight loss to regain some independence and get out and about again, helping to reduce isolation."
"The lenses may one day find their way into other areas as the research was being funded by Darpa, the research arm of the US military. "They are not so concerned about macular degeneration," he said. "They are concerned with super vision which is a much harder problem. "That's because the standard is much higher if you are trying to improve vision rather than helping someone whose eyesight has deteriorated," he said."

The U.S. Food and Drug Administration is urging ophthalmologists to report occurrences of adverse patient reactions caused by decorative contact lenses to its MedWatch program. The FDA is emphasizing the need to report adverse reactions, especially if the lenses were purchased without a prescription, as the agency can only take action against illegal sellers when violations are reported. Consumers can report decorative lens-related problems directly to their local FDA Consumer Complaint Coordinator.
Vistakon, Johnson & Johnson Vision Care, Inc., has introduced 1-Day Acuvue TruEye (narafilcon A) contact lenses, a silicone hydrogel daily disposable lens, in the U.S., the company announced. These lenses will "gradually replace" the TruEye (narafilcon B) line launched in the U.S. in 2010. In other news, the company has developed Healthy Vision & Contact Lenses, an educational resource for in-office, website, and social media use. Healthy Vision & Contact Lenses offers helpful "Do's and Don'ts" for handling and wearing contact lenses and offers some easy-to- follow steps on how to reduce the risk of contact lens-related infection through proper use and care of lenses as well as lens-care products such as contact lens cases.
