Optical coherence tomography in patients with somatotropin-producing pituitary adenoma

Optical coherence tomography (OCT) is widely used in ophthalmological practice. The review presents the results of OCT in patients with somatotropin-producing pituitary adenoma, or somatotropinoma, which is a hormone-active tumor of the adenohypophysis, characterized by excessive production of somatotropic hormone (STH). It stimulates the secretion of type I insulin-like growth factor (IGF-I). The mechanisms of STH action (pro-angiogenic action, stimulation endothelial cell proliferation and migration, development of endothelial dysfunction and retinal edema) requires much attention to the results of examination of patients with somatotropinomas using modern diagnostic methods, such as OCT.
