Effect of chronic high‐altitude hypoxia on retinal vascular phenotype, choroidal and retinal vasoreactivity in Peruvian highlanders

Experimental Physiology, Volume 111, Issue 10, Page 4814-4826, 1 October 2026.
Abstract High‐altitude chronic hypoxia can induce excessive erythrocytosis (EE, defined as a haemoglobin concentration of ≥21 g/dL in men), leading to hyperviscosity and promoting endothelial dysfunction. We aimed to assess whether EE affects the retinal vascular phenotype and the ophthalmological vascular response to CO2.

Miniaturized fundus camera

, 2003
We present a miniaturized version of a fundus camera. The camera is designed for the use in screening for retinopathy of prematurity (ROP). There, but also in other applications a small, light weight, digital camera system can be extremely useful.

Relationship between optic disc-foveal distance and choroidal and retinal nerve fibre thickness

Folia Morphologica
BACKGROUND: The optic disc-foveal distance is very important because it is an anatomical measure of the fundus. As this distance increases and the fundus tensions, there can be variability in retinal and choroidal thickness.
