San Francisco-The newest version (A2) of the Carl Zeiss Meditec software algorithm for quantification of retinal nerve fiber layer (RNFL) thickness using the third-generation optical coherence tomography (OCT 3) showed no improvement in glaucoma discriminating power compared with its predecessor software (A1), but it did reduce the variability of RNFL thickness measurements, according to a Tufts University glaucoma specialist.

San Francisco-Nearly 100,000 people in the United States are blind from glaucoma, and this number will rise enormously as the population ages over the next 20 years unless better detection and treatment methods are developed, said Nathan G. Congdon, MD, MPH.

Editor's Note: Anterior uveitis is the most common type of intraocular inflammation. Among patients with inflammation localized primarily to the anterior chamber, 50% or more are HLA-B27 positive. Inaddition, a number of these patients with HLA-B27-associated anterior uveitis have, or will develop, an associated systemicdisorder such as ankylosing spondylitis,reactive arthritis (formerly known asReiter's syndrome), inflammatory bowel disease, or psoriatic arthritis.

Orlando-The key to success in today's competitive contact lens market is to offer complete service and a full array of specialty contact lenses, according to one expert.

Woburn, MA-Advanced Vision Research has joined the growing number of physicians who have concluded that the anti-inflammatory properties of omega-3 fatty acids, such as those found in flaxseed oil, can relieve dry eye. The company recently added a dietary supplement containing these acids, TheraTears Nutrition, to its line of dry eye products.

Baltimore-LASIK presents a challenge to normal tear film dynamics, and some patients may be affected by prolonged neurotrophic epitheliopathy.

The paradigm of dry eye treatment is the use of solutions and lubricants applied to the eye. That is, dry eyes require topical medication in the form of artificial tears to restore tear production and comfort. Anything other than this is contrary to belief and intuition and a paradigm shift.

Los Angeles-Insertion of the Herrick Lacrimal Plug (HLP, Lacrimedics, Eastsound, WA) appears to be trouble-free for the majority of patients, with significant complications wuch as pyogenic granuloma and probing occurring in less than 10% of cases, said John C. Affeldt, MD, MPH.

Columbus, OH-Age-adjusted approaches are needed for the evaluation and management of suspected orbital fracture in pediatric patients because children are different from adults, according to JDespite the introduction of more accurate IOL formulas and biometry instrumentation, cataract and refractive lens surgery have yet to achieve the ophthalmologist's ideal of perfect emmetropia in all cases.1-5 This limitation stems from occasional inaccuracies in keratometry and axial length measurements, an inability to assess the final position of the pseudophakic implant accurately in a fibrosing capsular bag, and the difficulty of completely eliminating pre-existing astigmatism despite the use of limbal relaxing incisions and toric IOLs.6,7 A new lens technology offers the hope of taking ophthalmologists one step closer to achieving emmetropia in all cases and also perhaps further improving the final result by addressing higher-order optical aberrations.
