Duration of the depressive episode is correlated with ganglion cell inner plexifrom layer and nasal retinal fiber layer thicknesses: Optical coherence tomography findings in major depression

Optical coherence tomography (OCT) is a relatively new, noninvasive imaging technique that has been used increasingly to diagnose and manage a variety of retinal diseases. Since the axons in retinal nerve fiber layer (RNFL) are nonmyelinated within the retina, OCT has been used in various neurodegenerative diseases to visualize the process of neurodegeneration. Decreases in RNFL and ganglion cell inner plexiform layer (GCIPL) thicknesses were...
