Application of OCT for choroid thickness examination

Y. Zdravkov, I. Tanev

Abstract

The choroid represents thin, pigmented and vascular lamina. In healthy eye, it supplies the nutrition either of retinal pigment epithelium or outer retina, and secures the colour of ocular fundus, and also plays an important role in the thermoregulation. There is a great variability in the choroidal thickness according to various factors as age, gender, refraction and others. First measurements of choroidal thickness could be traced to the beginning of 20th century, implementing and developing number of methods and techniques, which now are considered as outdated, just to reach nowadays` dominant-the optical coherence tomography (OCT). The choroidal thickness examination by OCT discovers new horizons for better understanding and treating of various retinal and chorioretinal disorders.
