摘要

年龄相关性黄斑变性(AMD)是65岁以上人群不可逆视力丧失的最常见原因。它的起源是多因素的,涉及衰老以及吸烟、肥胖和饮食等各种遗传和环境因素。它主要影响黄斑区的外视网膜(视网膜色素上皮和感光细胞)。它分为“非新生血管”和“新生血管”。“非新血管”形式的特征是存在软核膜,可演变为进行性黄斑萎缩和视力逐渐丧失。在“新生血管”形式中,异常血管发展,通常从脉络膜生长到视网膜下或上皮下色素间隙,伴随着液体和血液的渗出,突然失明。这会导致外视网膜纤维化和不可逆转的损伤。本文分析了年龄相关性黄斑变性的分类和治疗现状。

Tratamiento actual de la degeneración macular relacionada con la edad

Age related macular degeneration (AMD) is the most common cause of irreversible vision loss in people over 65 years of age. Its origin is multifactorial, involving aging as well as various genetic and environmental factors such as smoking, obesity and diet. It mainly affects the outer retina (retinal pigment epithelium and photoreceptors) in the macular area. It is classified into “non-neovascular” and “neovascular”.

The “non-neovascular” form is characterized by the presence of soft drusen, which can evolve towards progressive macular atrophy and a gradual loss of visual acuity. In the “neovascular” form, abnormal blood vessels develop, usually growing from the choroid, into the subretinal or subepithelial pigment space with exudation of fluid and blood with sudden loss of vision. This leads to fibrosis and irreversible damage to the outer retina.

This article analyzes the classification and current state of treatment of age-related macular degeneration.
