December 1st 2006East 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.
Vitamin A deficiency returns to an unsuspecting audience
December 1st 2006Houston-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.
Operating microscope offers 'lightless cataract surgery'
December 1st 2006London-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.
Better PK results foreseen with custom overlapping incision shapes
November 15th 2006London- 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.
Dispensing Ophthalmology provides online resources
November 15th 2006Clinton, 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.
Presbyopia-correcting IOLs next step for refractive surgery
November 15th 2006Fewer 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.
Newer methods of evaluating IOP emerge, call for validation
November 15th 2006Minneapolis-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.
Anterior segment OCT useful for calculating IOL tilt, decentration
November 15th 2006London-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.
New HRT software maintains excellent discriminatory performance in study
November 15th 2006Pittsburgh-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.
Spatial frequency doubling excellent tool to predict progression in glaucoma
November 15th 2006Canberra, 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.
Early adopters cite promise of pattern-scan photocoagulation
November 15th 2006The 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.
Non-contact technology offers easy measurement of central pachymetry
November 15th 2006Bonita 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.
Telemedicine a viable solution for ROP evaluation
November 15th 2006Calgary, Alberta-Serial digital fundus imaging with remote interpretation by experienced physician graders is accurate for detecting clinically significant retinopathy of prematurity (CSROP), according to the results of the Photographic Screening Trial for Retinopathy of Prematurity (PhotoROP).
Canaloplasty with tensioning sutures results in IOP lowering
November 15th 2006London-A reduction in IOP in patients with open-angle glaucoma can be achieved after nonpenetrating glaucoma surgery (canaloplasty) when circumferential suturing is done in the inner wall of Schlemm's canal. This technique results in distension of Schlemm's canal and enhanced outflow of aqueous with the subsequent lowering of the IOP, explained Norbert Koerber, MD, at the XXIV Congress of the European Society of Cataract and Refractive Surgeons in London.
