Central Serous Chorioretinopathy
Fig. 18.1 Acute central serous chorioretinopathy. SD-OCT showing high height of subretinal fluid relative to the basal diameter of the fluid 18.2.2 Fibrin in Central Serous Chorioretinopathy As early as…
Myopic Macular Pathologies
Fig. 22.1 Myopic staphyloma. SD-OCT showing deep posterior staphyloma. Both edges of the structure are inverted and delineated as an inverted image Because of relatively small pathology and unstable fixation,…
Neovascular Age-Related Macular Degeneration
OCT feature Description PED (pigment epithelial detachment) Areas of detached pigment epithelium. The lesion is filled with serous fluid and/or fibrovascular tissue SHRM (subretinal hyperreflective material) Thickening of the outer…
