Myopic keratophakia considered alternative for correction of high myopia
July 1st 2006San Francisco-Correction of high myopia with a phakic IOL or by clear lens exchange does pose some risk for patients because these methods are intraocular procedures. To avoid the associated risks of IOL surgery-such as infection, cataract formation in the case of phakic lenses, possible endothelial damage, pupil ovalization, zonular problems, and retinal problems, surgeons might want to consider myopic keratophakia and excimer laser ablation instead, explained Luis Antonio Ruiz, MD.
Graduates of the class of 2006, we salute you!
July 1st 2006Recently it was that time of the year for my medical school's graduation ceremony. Three hours and forty-five minutes of speeches and handing out diplomas, wearing warm academic regalia in an auditorium that could have used more air conditioning-I think you all have been there and know the drill. Deans, vice deans, assistant deans, and department chairmen are accorded the honor of sitting up on the stage, so we get a close-up view of the proceedings.
NEI: millions have visual impairment
July 1st 2006Bethesda, MD-Of the 14 million Americans that are visually impaired, more than 11 million have uncorrected visual impairment, such as nearsightedness, according to a study designed and supported by the National Eye Institute (NEI) of the National Institutes of Health (NIH) (JAMA 2006;295:2158-2163).
UC-Irvine receives $2 million donation
July 1st 2006Irvine, CA-The philanthropic arm of Allergan Inc., The Allergan Foundation, donated $2 million to the University of California-Irvine's (UC-Irvine) department of ophthalmology. The donation will further strengthen the department's research agenda and clinical care.

NJ ophthalmologist reported first U.S. Fusarium case
July 1st 2006For weeks, he was known publicly only as the "New Jersey ophthalmologist" who was anonymously credited with alerting the U.S. Centers for Disease Control and Prevention (CDC) about an apparent rise in the number of Fusarium keratitis cases he had seen.
Genentech receives approval for Lucentis as treatment for wet AMD
June 30th 2006South San Francisco, CA - Genentech Inc. announced on Friday, June 30, 2006 that the FDA has approved its ranibizumab 0.5 mg injection (Lucentis, Genentech Inc.) for the treatment of neovascular (wet) age-related macular degeneration (AMD). The FDA approved Lucentis after a 6-month priority review, the company said. Genentech will begin shipping product immediately. Ninety-five percent of patients treated with Lucentis maintained their vision in phase III clinical trials, according to the company. Vision improved by at least three lines (or 15 letters) on the study eye chart in up to 40% of these patients at 1 year. Lucentis was developed for intraocular use to treat the underlying cause of wet AMD by targeting the molecular pathway that controls angiogenesis. Lucentis is designed to bind and inhibit VEGF-A, a protein that is believed to play a critical role in angiogenesis.

Typical microvascular third-nerve palsy requires checklist
June 15th 2006La Jolla, CA-When diagnosing a cranial third-nerve palsy, there are a number of factors to consider that let the ophthalmologist decide whether a patient's third-nerve palsy is microvascular, or whether the cause is a more serious one. Leah Levi, MBBS, described the checklist that she uses to arrive at the diagnosis of microvascular third-nerve palsy.
Many conditions masquerade as bacterial keratitis
June 15th 2006S?o Paulo, Brazil-Establishing the correct diagnosis and modifying therapy appropriately based on response are fundamental elements in the successful management of bacterial keratitis, said Richard L. Abbott, MD, at the World Congress of Ophthalmology.
Austrian first to describe iris nodules of neurofibromatosis
June 15th 2006After extensive ophthalmological training in Vienna and Innsbruck, Carl Lisch (1907-1999), an Austrian ophthalmologist, became the chief of ophthalmology in W?rgl, a small town in the North Tyrolean region of Austria. He practiced in W?rgl from 1947 to 1980. During his lifetime he wrote approximately 120 papers focusing primarily on the phakomatoses and in particular neurofibromatosis.
Tips help enhance surgical efficiency
June 15th 2006San Francisco-Attention to safety, speed, staffing, standardization, simplicity, and suppleness is the key to efficiency and effectiveness in the operating room (OR), explained Bradford J. Shingleton, MD, at glaucoma subspecialty day during the American Society of Cataract and Refractive Surgery annual meeting.
Genetic testing helps physicians zero in on ocular disease
June 15th 2006Ann Arbor, MI-Scientists at the University of Michigan Kellogg Eye Center have developed a faster and more cost-effective method of genetic testing for autosomal recessive forms of retinitis pigmentosa (arRP). Using this microarray-based sequencing technology, researchers can look for disease-causing mutations on 11 genes at a time, according to Radha Ayyagari, PhD.
Aqueous shunt use increasing as indications appear to broaden
June 15th 2006S?o Paulo, Brazil-While aqueous shunts have traditionally been reserved for use in refractory glaucomas having poor surgical prognoses, glaucoma surgery appears to be undergoing a paradigm shift in which shunts are taking on a larger role, said Steven J. Gedde, MD, at the World Ophthalmology Congress.
