Abstract

The optical coherence tomography (OCT), a non-invasive and noncontact diagnostic method, was introduced in 1995 for imaging macular diseases. In diabetic macular edema (DME), OCT scans show hypo reflectivity, due to intraretinal and/or sub retinal fluid accumulation, related to inner and/or outer blood–retinal barrier breakdown. OCT tomograms may also reveal the presence of hard exudates, as hyper reflective spots with a shadow, in the outer retinal layers, among others. In conclusion, OCT is a particularly valuable diagnostic tool in DME, helpful both in the diagnosis and follow-up procedure.
