How to Identify Macular Edema in OCT Examination

Editor’s Note Optical Coherence Tomography (OCT) is a rapidly developing ophthalmic examination technology in the past decade. It uses the principle of low-coherence light interferometry to scan and obtain two-dimensional or three-dimensional structural images of biological tissues, equivalent to a cross-sectional scan of the eye tissues.

Macular Edema (ME) Observed through OCT

☞ Different reflective signals of normal retinal tissue in OCT: 1. The nerve fiber layer and the retinal pigment epithelium exhibit high reflectivity. 2. The plexiform layer and nuclear layer show moderate reflectivity. 3. Photoreceptor cells have low reflectivity. ☞ Normal retinal thickness: 1. The distance from the vitreoretinal interface to the anterior surface of … Read more
