One year after initial presentation and additional PRP, virtually no hemorrhages remain near the arcades in this image. Both old laser photocoagulation (pigmented) and more recent laser photocoagulation (not pigmented as yet) are visible in the same fundus image above.

Although the hemorrhage was treated with PRP, it worsened over a 3 month period as revealed in the comparison fundus images above.

Case 1: Topcon OCT 3D Image OD The 3 dimensional OCT above left demonstrates the elevation of the posterior hyaloid. Note the difference in appearance of the dense hemorrhage (red arrow) from the scattered red blood cells.

Case 1: Topcon 3D OCT Raster Scan Images OD A horizontal section above the visible hemorrhage reveals the posterior hyaloid and scattered red blood cells (which appear as hyperreflective dots) that have not yet settled.

The patient presented 3 months later and the hemorrhage worsened. Note that the hemorrhage blocks the large retinal vessels and is hence in front of them. The flat top is due to sedimentation of the red blood cells. Large choroidal vessels are visible because of the retinal thinning associated with high myopia.
