At any point 1–5 days following ascent to altitudes≥ 2500 m, individuals are at risk of
developing one of three forms of acute altitude illness: acute mountain sickness, a syndrome …

With rising altitude the partial pressure of oxygen falls. This phenomenon leads to hypobaric
hypoxia at high altitude. Since more than 140 million people permanently live at heights …

People living in a high-altitude environment have distinct lifelong challenges. Adaptive
mechanisms have allowed high-altitude residents to survive in a low-oxygen environment …

Individuals ascending rapidly to altitudes> 2500 m may develop symptoms of acute
mountain sickness (AMS) within a few hours of arrival and/or high-altitude pulmonary edema …

Purpose: This study aimed to quantify the impact of high altitude on choroidal thickness and
relate changes of altered choroidal blood flow to clinical parameters and acute mountain …
