Aim-A case-control study was initiated to determine the risk factors for the development of age related macular degeneration (AMD).
Methods-Study
19).Conclusions-This large case-control study confirms some of the risk factors previously identified and may contribute to the determination of methods for prevention of AMD. (Br J Ophthalmol 1998;82:996-1002) Age related macular degeneration (AMD) is the most common cause of blindness in people over 55 years of age in developed countries. The pathogenesis of this condition is still putative 1 and, in absence of therapy, there is a need to identify risk factors associated with AMD in an eVort to preclude its development.Following the Framingham Eye Study, 2 a number of epidemiological studies have attempted to identify risk factors for AMD.
2-23These studies, which were case-control and population based, have provided informative but controversial data. The goals of the present study were to further explore the possible link between environmental factors and systemic and ocular conditions that may be risk factors for AMD in a European population.Based upon previously published reports, we studied the following risk factors in a casecontrol study: present and past smoking habits, coronary artery disease, systemic hypertension, ametropia, iris colour, and lens status.
Admixtures stored at 4 degrees C (pH 7.90 +/- 0.004; mean +/- SD) are stable for 48 hours. The CYP and mesna combination can be infused at room temperature over 6 hours without significant degradation of the drugs. Stabilities are dependent on pH, temperature, and/or concentration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
