E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Pseudophakic macular edema is a pathology that results from cataract surgery, usually occurring 4-6 weeks after surgery, which directly affects the retina (specifically the macula, the region that provides maximum visual acuity). In this condition, for different reasons, an inflammatory exudate accumulates in the different layers of the retina and can lead to affect the visual acuity, to severe retinal alterations both acute or chronic. |
El edema macular pseudofáquico es una patología derivada de la cirugía de cataratas que ocurre generalmente entre las 4-6 semana posterior al acto quirúrgico, que afecta directamente a la retina (específicamente la mácula, región que brinda la máxima agudeza visual). En esta condición, por diversos mecanismos se acumula un exudado inflamatorio en las distintas capas de la retina que puede llevar a afectar la agudeza visual, hasta alteraciones retinianas mas severas tanto agudas como crónicas. |

E.1.1.1 | Medical condition in easily understood language |
Pseudophakic macular edema is a condition that can occur postoperatively in cataract surgery consisting on fluid accumulation in the retina. |
El edema macular pseudofáquico es una condición que puede ocurrir en el postoperatorio de la cirugía de cataratas que consiste en la acumulación de líquido en la retina. |
