Baltimore-Results of a prospective randomized trial conducted in Ethiopia demonstrated that a single dose of oral azithromycin (Zithromax, Pfizer) after trichiasis surgery safely and significantly reduced trichiasis recurrence compared with a 6-week course of topical treatment with tetracycline ointment, reported Sheila K. West, PhD, and colleagues.
Loma Linda, CA-Recovery of full visual function is possible in eyes with stage IV diffuse lamellar keratitis (DLK) using a novel management paradigm that is based on a new pathophysiologic model of the disorder, said Brian R. Will, MD, assistant clinical professor of ophthalmology, Loma Linda University School of Medicine, Loma Linda, CA.
New options for patients, such as multifocal IOLs; refinements in surgery, such as Descemet's stripping automated endothelial keratopathy (DSAEK); and encouraging results from technology in the pipeline, such as intracorneal inlays, which would provide another new avenue for patients with presbyopia; as well as high marks received by the femtosecond laser (IntraLase FS, IntraLase Corp.) for cutting flaps-these are but a few of the refractive surgery high points of 2006 cited by ophthalmic surgeons.
The year 2006 may be characterized as an interesting one in cataract surgery, according to ophthalmologists who are opinion leaders in the field.
If Congress should offer a financial bonus to physicians who participate in a voluntary Medicare physician-reporting program, ophthalmologists will be ready.

San Diego-TargeGen Inc. has initiated a single-site phase I clinical trial involving TG100801, a small molecule, topically applied multi-targeted kinase inhibitor for the treatment of age-related macular degeneration (AMD) and other debilitating diseases of the eye.
East Hanover, NJ-The FDA has approved the over-the-counter (OTC) use of ketotifen fumarate ophthalmic solution 0.025% (Zaditor) for the temporary prevention of itchy eyes due to allergic conjunctivitis. The drops treat eye itch associated with pollen, ragweed, grass, animal hair, and dander without the potentially negative effects of a decongestant.
Houston-Intestinal surgeries-such as gastric bypass, resections of the large and small bowel, and gallbladder removal-may interfere with the intestine's ability to absorb vitamin A, resulting in the potential for severe deficiencies and compromised vision.
London-A new operating microscope for cataract surgery that uses near-infrared light to illuminate the surgical field offers several advantages compared with the conventional microscope, including possible faster visual recovery and the potential to avoid phototoxic retinopathy.
Novagali Pharma, a French biopharmaceutical company specializing in ophthalmology, has completed the enrollment for its phase III study to evaluate the efficacy and safety of a potential treatment for vernal keratoconjunctivitis (VKC). Enrollment for the international study was completed much earlier than expected, the company said, indicating an unmet need for a treatment.
Biovitrum, a Stockholm-based biopharmaceutical company, has initiated a clinical phase II study with the candidate drug BVT.28949, a 5-HT2A antagonist for treating glaucoma.
London- One of the most revolutionary technological changes in corneal transplant surgery in decades is beginning to hit clinics around the world. A software and hardware upgrade for the femtosecond laser (IntraLase FS, IntraLase Corp.) has been released to help surgeons design custom incision shapes that improve surgical precision and promote faster healing.
Clinton, CT- Ophthalmology Resources LLC recently launched Dispensing Ophthalmology online, a virtual tool to help make optical dispensaries more successful and more profitable. Dispensing Ophthalmology, located at www.dispensingophthalmology.com, provides access to and complete details on two new services: optical production tracking and Medicare post-cataract eyewear education.
Fewer than 10 years ago I sat in the audience at the first "Array Familiarization Course" offered in San Francisco at the conclusion of the American Academy of Ophthalmology annual meeting. A highlight of the course for me was I. Howard Fine, MD's response to a question about the best refractive procedure for a 60-year-old patient with 6 D of myopia. The first FDA approvals for excimer laser ablation recently had come through, and LASIK was on everyone's mind. Dr. Fine, however, proposed refractive lens exchange with the Array lens, offering complete spectacle independence. The idea clicked.
Miami-When other possible treatments for ectasia fail, lamellar or penetrating keratoplasty (PK) may be the last resort for these patients.
Minneapolis-Alterations in corneal properties in both keratoconus and Fuchs' corneal dystrophy can affect the accuracy of Goldmann tonometry, highlighting the importance of validating newer methods of measuring IOP and of further studying the metrics of corneal biomechanical properties, according to Jeff Sanderson, MD, an ophthalmologist in private practice in Minneapolis.
London-Anterior segment optical coherence tomography (AS-OCT) (Visante OCT system, Carl Zeiss Meditec) can be used to calculate IOL tilt and decentration and may have an advantage of being able to provide accurate measurements in eyes with an irregular pupil or cornea, said Richard Lee, BSc.
Pittsburgh-The Glaucoma Probability Score (GPS), the new mathematical model featured in the Heidelberg Retina Tomograph 3 (HRT3, Heidelberg Engineering) software, eliminates subjective operator input in defining the optic disc margin and performs comparably to the HRT II in discriminating between healthy and glaucomatous eyes, according to a study undertaken by researchers at the University of Pittsburgh.
Canberra, Australia-Spatial frequency doubling (FD) stimuli have an excellent ability to predict progression of visual field loss and optic disc abnormalities for about 3 years in patients with glaucoma, but the predictive power of one assessment on its own drops off over time, said Ted Maddess, PhD, a senior fellow (associate professor) in the visual sciences group, Research School of Biological Sciences, Australian National University, Canberra, Australia.
The use of a pattern-scan laser system (Pascal Photocoagulator, OptiMedica Corp.) to treat diabetic retinopathy and other retinal disorders is showing substantial advantages over conventional single-burn techniques, according to a growing body of clinical experience. Early adopters say key attributes include better targeting of photocoagulation burns to fit specific retinal conditions, less patient discomfort due to lower applied laser power, and improved overall clinical efficiency because the number and duration of treatments are sharply reduced.
Bonita Springs, FL-The rotating Scheimpflug camera-based Pentacam system (Oculus) seems to provide an easy-to-use tool for obtaining reliable corneal pachymetry measurements, said Stephen E. Pascucci, MD, a private practitioner in Bonita Springs, FL.
