Abstract

L'invention porte sur un nouvel agent prophylactique ou thérapeutique pour des maladies choriorétiniennes. Le temsirolinus, l'évérolimus et similaires, qui sont des dérivés du sirolimus, présentent une excellente activité anti-angiogénique dans une rétinine et une choroïde, et sont par conséquent utiles comme agents thérapeutiques pour des maladies choriorétiniennes, telles que la dégénérescence maculaire liée à l'âge.
