Glossary and Index 151
Metamorphopsia: Distortion in vision caused by fluid beneath or in the retina typically seen as a straight line looking bent. It is a common first symptom of neovascular AMD; 61.
Microscopic spectacles: High-powered convex lenses that magnify objects that are held close to the eye. The lenses are usually mounted into eyeglasses and prescribed for one eye only.
MIRA-1: The acronym for the Multicenter Investigation of Rheophoresis for AMD. Patients with AMD are randomized so that two-thirds of them receive rheophoresis and one-third receive a sham treatment. Results are expected in early 2006; 84.
Neovacular AMD: See wet AMD.
Novartis: The drug company that makes and sells verteporfin for Visudyne® treatment.
Occult choroidal neovascularization: This type of abnormal blood vessels fills more slowly with fluorescein than classic neovascularization and leaks less. Occult neovascularization often doesn’t have a sharp boundary like classic neovascularization and tends to progress slower.
Obesity: Twenty to thirty percent above ideal body weight; 30, 37.
Omega-3 poly-unsaturated fatty acids: A group of fatty acids that include linolenic acid, DHA, and EPA which are helpful to reduce the risk of heart disease and AMD; 45, 49.
Omega-6 fatty acids: A group of fatty acids including linoleic acid. Although essential for body functions, they promote inflammation, heart disease, and AMD if taken in too high quantities compared to omega-3 fatty acids; 46, 47, 48
Optic Coherence Tomography (OCT): An imaging test using low-intensity laser to create a cross-section view of the retina. The test helps the eye doctor determine whether there is fluid beneath or within the retina; 77.
Optical device: Any system of lenses that enhances vision function.
