Inner Retinal Layer and Outer Retinal Layer Findings after Macular Hole Surgery Assessed by means of Optical Coherence Tomography

Figure 4

Optical coherence tomography (OCT) angiography in a case of degenerative lamellar macular hole. Superficial vascular plexus (top left panel) and deep vascular plexus (top middle panel) illustrate alterations of the foveal avascular zone, corresponding to the lamellar loss of inner retinal tissue. Segmentation at the level of the choriocapillaris (top right panel) demonstrates normal perfusion. The exact segmentation of the superficial vascular plexus, deep vascular plexus, and choriocapillaris (bottom panel) is illustrated on B-scan OCT with blood flow superimposed (red flow for retinal circulation and pink flow for choroidal circulation).
