Three separate studies on eye health examine the role of antioxidant supplements, the relationship of visual acuity and mortality, and the causes of glaucoma in the May 2008 issue of Ophthalmology, the journal of the American Academy of Ophthalmology.

Gene therapy has been used successfully to improve visual function in a patient with a genetic disorder of the retina, Leber's congenital amaurosis (LCA), as reported in a study published online ahead of print by the New England Journal of Medicine.

VEGF Trap (Regeneron) maintains a significant improvement in the visual acuity of neovascular age-related macular degeneration (wet AMD) patients up to 32 weeks, according to a study presented at this year's Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO).

Xibrom (bromfenac 0.09 mg ophthalmic solution; ISTA Pharmaceuticals) significantly improves visual acuity outcomes and lowers retreatment rates when administered as an adjuvant to Lucentis (ranibizumab; Novartis) therapy in neovascular age-related macular degeneration (AMD) patients, when compared with Lucentis monotherapy, according to a poster presented at this year's Annual Meeting of the Association for Research in Vision and Ophthalmology (ARVO).

The Collaborative Initial Glaucoma Treatment Study (CIGTS) showed that substantially lowering IOP, whether through medication or surgery, can prevent vision loss. One of the major trials of recent years, CIGTS also showed that surgery was an effective first-line treatment and had important findings on quality of life.

The iCare tonometer (Tiolat) has been approved for use in China by the country's State Food and Drug Administration (SFDA); the tonometer is now approved in every major global market.

Paediatric cataract surgery, particularly when performed in patients under the age of nine months, entails a substantial risk of post-surgical glaucoma, according to a study published in the January 2008 issue of Investigative Ophthalmology and Visual Science.

The American Society of Cataract and Refractive Surgery (ASCRS) survey results for 2008 pointed out some changing trends in infectious keratitis after LASIK and PRK compared with previous surveys conducted in 2002 and 2005, said Terry Kim, MD.

With the increasing number of multifocal and accommodative intraocular lens (IOL) implantations being carried out, cataract surgery is fast becoming another form of refractive surgery.

Outcomes in a cohort including more than 5000 eyes support the conclusion that an implantable collamer lens (Visian ICL; STAAR Surgical) is a safe, predictable, and very effective method for correcting high-to-moderate myopia, said John R. Moran, MD, PhD.

Hypoesthesia is not the origin of post-LASIK punctuate epithelial keratopathy or the so-called dry eye syndrome. Rather, these sequelae may represent a phototoxic effect of treatment with the ultraviolet excimer laser, said Carmen Barraquer-Coll, MD.

Early experience from a pilot study shows that spherocylindrical error after cataract surgery can be corrected with a proprietary light-adjustable lens (LAL; Calhoun Vision) to improve uncorrected visual acuity (UCVA), said Arturo S. Chayet, MD.

The first World Glaucoma Day was held March 6. The World Glaucoma Association (WGA) and the World Glaucoma Patient Organization (WGPA) sponsored the observance. The Ophthalmology Times Group was the official news source of the event, providing e-newsletter coverage of the awareness and educational activities organized by glaucoma institutions and local patient support groups worldwide.
