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.

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.
Learn how to prepare, store lamellar corneal grafts
June 15th 2006Khon Kaen, Thailand-A study of a new approach to preparation and storage of posterior lamellar corneal grafts for transplantation has demonstrated that centralized harvest, cold storage, and shipment by airmail result in viable grafts 2 days later, according to Olan Suwan-apichon, MD, assistant professor, department of ophthalmology, faculty of medicine, Khon Kaen University, Khon Kaen, Thailand.
Difficult cataract cases aided by use of OVD
June 15th 2006San Francisco-DisCoVisc (Alcon Laboratories) performs better than Healon 5 (Advanced Medical Optics) during cataract surgery in patients who have been taking tamsulosin HCl (Flomax, Boehringer Ingelheim), which is a culprit in the intraoperative floppy iris syndrome (IFIS), according to Satish Modi, MD, FRCS (C).
Centers to evaluate TASS outbreaks
June 15th 2006The American Society of Cataract and Refractive Surgery (ASCRS) has established a center at the University of Utah to evaluate unexplained cases of postoperative inflammation or endophthalmitis. This center is under the direction of Nick Mamalis, MD, who has developed protocols to be used in the evaluation of patients with TASS.
