In this OCT image you will note an epiretinal membrane (arrows). There is also intraretinal fluid best described as diffuse outer retinal thickening (circle). There is some overlying inner retinal opacification (stars). In combination this set of features is consistent with macular edema after a retinal vein occlusion. Remember, it is the constellation of findings that allows accurate OCT interpretation. Epiretinal membranes can cause retinal thickening, but not in this pattern. While you will certainly supplement OCT testing with clinical evaluation, learning pattern groupings remains critical to improving your diagnostic skills. EyeCarePD will be releasing a short video explaining this particular pattern seen on OCT scans in patients with retinal vein occlusions so be sure to sign-up for the newsletter to get a notification directly to your inbox.Want to be able to interpret OCTs like an expert?
