A pepidomimetic inhibitor of the receptor for C5aR (JPE1375) blocks the mechanism that draws inflammatory cells into the disease process of age-related macular degeneration (AMD). When blocked, the numbers of neutrophils and macrophages decrease substantially, and in turn, choroidal neovascularization (CNV) also decreases, according to Anthony Adamis, MD, Department of Ophthalmology & Visual Sciences, University of Illinois.

Twenty-five-gauge sutureless vitrectomy has been increasing in popularity. In conjunction with this surge, however, is the observation that the procedure is associated with increased postoperative complications such as hypotony, choroidal detachment, and an increased incidence of endophthalmitis. Richard Kaiser, MD, from the Retina Service of Wills Eye Institute, Philadelphia, focused on endophthalmitis and noted that the 25-gauge procedure has a risk of infection that is 12.4 times greater than the 20-gauge procedure.

Alcon Inc. has executed a new agreement and broadened an existing agreement with two different companies to expand its products under development.

A proprietary purified human neural stem cell product (HuCNS-SC, StemCells), when transplanted into a well-established animal model, may protect the retina from progressive degeneration, according to researchers.

The multi-component IOL (PrecisionLens) is a novel, foldable implant technology consisting of three optical elements (two exchangeable) that was created to produce an emmetropic result reliably in all patients who undergo cataract surgery or refractive lens exchange.

Arriving at the proper IOL power is difficult to achieve in patients who have undergone prior cornea-altering refractive procedures such as LASIK, PRK, or RK.

The American Academy of Ophthalmology (AAO) has announced the participants for its 2009 Leadership Development Program (LDP).

Postoperative anterior optical coherence tomography may provide a more accurate measurement of LASIK flap thickness than intraoperative subtraction pachymetry.

The state-of-the-art material and design of a novel one-piece IOL can offer refractive stability and predictability, according to Daniel A. Black, MBBS, FRACO, FRACS. This newer IOL rivals other more established IOLs and may soon become the gold-standard treatment in cataract procedures, he said.

Prophylactic intracameral cefuroxime injections prevent the development of endophthalmitis after cataract surgery, according to results of the European Society of Cataract and Refractive Surgeons Endophthalmitis Study. The finding remains controversial in the United States, where cefuroxime has not been approved by the FDA and the standard of care to prevent endophthalmitis after cataract surgery is the administration of preoperative, perioperative, and postoperative topical fluoroquinolone drops.

A cataract surgeon who first identified intraoperative floppy iris syndrome (IFIS) and its association with tamsulosin describes several approaches to managing the surgical complication. The approach a surgeon uses will depend on the severity of IFIS, he says.

Ophthalmic practice administrators know that keeping physicians happy is crucial to the practice's overall success. And the best way to do that is by making sure their incomes are continually growing.

Depending on your location, your specialty, and the size of your practice, insurers may actually want to keep you happy, especially if you threaten to walk away from a bad deal. If nothing else, negotiations may reveal that lowball reimbursement for a particular code is nothing more than an inadvertent mistake that most insurers are willing to correct.

Physician groups are adopting tougher collection tactics, largely in response to tough times. What compounds their problem of skimpy third-party reimbursements and rising overhead is having to depend on patients for a bigger portion of their revenue stream-a result of the rising number of uninsured and the growth of high-deductible health plans.

Losing even one patient to another local practice is one too many. To achieve and maintain an edge in the LASIK market, you've got to stay on top of your competitors with research and analysis, and regularly evaluate where you fit in terms of image and consumer perception.

Organized medicine's "victory" resulted in postponing harsh reductions in payments to physicians for Centers for Medicare and Medicaid Services.

Safety and efficacy outcomes from a five-year study indicate that intravitreal triamcinolone can be an appropriate treatment in selected patients with advanced diabetic macular edema. Beneficial effects persisted throughout the study period, and no unexpected adverse events were seen.

In an evaluation of the anatomic changes of CNV lesions, patients treated with ranibizumab (Lucentis, Genentech) in the PIER study had smaller changes than patients who had received sham injections.

An analysis of data from a study of eye disease in Latinos provides additional evidence that interleukin-8 (IL-8) may play a role in the development or progression of age-related macular degeneration.

Results from the Age-Related Eye Disease Study (AREDS) showed that participants assigned to take zinc dietary supplements had lower mortality than participants not assigned to zinc supplements. The long-term study also indicated that poorer survival was associated with AMD.

A telemedicine program, in which images allow patients to virtually visit with doctors, can be a valuable tool in the early detection, management, and treatment of diabetic retinopathy.

In some circumstances, it may be unnecessary to obtain images simultaneously with a confocal laser scanning system and optic disc photography, suggests a new study.

Use of spectral-domain optical coherence tomography with automated image processing seems to provide more objective and potentially more reproducible assessments of the optic nerve head when compared with ophthalmologists' assessments of conventional fundus photos.

The American Academy of Ophthalmology (AAO) is pleased to announce Harvey V. Fineberg, MD, PhD, president of the Institute of Medicine, as this year's keynote speaker.

ISTA Pharmaceuticals, Inc. has entered into an agreement with Deerfield Management, Sprout, and Sanderling Ventures, three of its long-term shareholders, to provide it with up to $65 million in financing through a flexible credit facility.

Topical, periocular, and/or systemic corticosteroids typically are used to treat corneal endothelial graft rejection. When those modalities fail, experience in a series of five eyes suggests intracameral triamcinolone acetonide may be worth considering.

Using standardized terminology, such as that in the Birmingham Eye Trauma Terminology system, to describe trauma to the globe eliminates misrepresentation of the injury.

The high-tech devices available today are changing the way ophthalmology is practiced. According to the surgeon, the new technology found in state-of-the-art optical coherence tomography goes much further than assisting ophthalmologists in the diagnostics of anterior eye and retinal disorders.
