Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What retinal structures were observed and assessed both qualitatively and quantitatively with OCT in the research in this Journal?
A
Internal Limiting membrane, Ellipsoid Zone, Retinal Pigment Epithelium
B
External Limiting membrane, Retinal Pigment Epithelium, Bruch’s membrane
C
Inner Nuclear Layer, Retinal Pigment Epithelium, Membrane Bruch
D
External Limiting membrane, Ellipsoid Zone, Retinal Pigment Epithelium
Explanation: 

Detailed explanation-1: -With OCT, the analysis of single retinal layers thickness showed a slight progressive thinning of the inner retina layers, specifically RNFL, GCL, IPL, and INL and a mild thickening of ORL in diabetic eyes compared to controls, even if a statistically significant difference was not reached.

Detailed explanation-2: -The ellipsoid zone (EZ), formerly known as the inner/outer segment of photoreceptors (IS/OS), refers to the second hyper-reflective band on an optical coherence tomography (OCT) image (Fig.
