Glossary and Index 155
VERITAS: A study just underway. The acronym stands for VERteporfin (Visudyne®) plus two different dose regimens of Intravitreal Triamcinolone Acetonide versus Visudyne® plus intravitreal pegaptanib (Macugen®) in patients with Subfoveal choroidal neovascu-larization secondary to age-related macular degeneration.
Verteporfin: The dye used in Visudyne® treatment. It absorbs light and gives off free radicals which damage new blood vessels in AMD; 65, 79.
Visual acuity: A measure of sharpness of vision as related to the ability to distinguish the details and shapes of objects at a designated distance. Normally used as a measurement of central (macular) vision; 84, 92, 102, 103, 106.
Vision impairment: Any amount of vision loss that affects an individual's ability to perform the task of daily life resulting from damage or disease to the visual system or the result of the visual system not being formed correctly; 102, 105, 113.
Visudyne®: A type of photodynamic treatment that uses verteporfin as the excitable dye and has been proven to reduce vision loss in neovascular AMD compared to no treatment; 64.
Vitamins for AMD; 39, 41, 48, 49, 50.
Weight Loss: And its effect on AMD; 37.
Wet AMD: New blood vessels have grown and are leaking fluid or blood beneath and within the macula; also called neovascular AMD; in distinction to dry AMD; 10.
Zeaxanthin: A carotenoid pigment found in the macula; 43.
