(Summary description)Retinal Macroaneurysm revealed by 3D full range SS-OCTA! An 82-year-old female who had a history of arteriosclerosis complained vision loss in her right eye. The visual acuity was 20/50 in her right eye while 20/30 in her left eye. Intraocular pressure in both eyes was normal. Color fundus images discovered bilateral refractive media opacity and a spindle-shaped lesion nearby a small branch retinal artery inferotemporal to optic disc in her right eye (fig. 1 blue circle). High-resolution B-scan image revealed thickened retina with subretinal fluid (fig. 1 thickness map). An oval hyperreflective entirety was found located in the internal retina with relatively low internal reflection, corresponding to the spindle-shaped lesion on color fundus and SLO image (fig.1 blue arrow). 12mm x 12mm OCTA image clearly showed a retinal macroaneurysm with internal blood signals detected on the flow-overlaid B-scan image (fig. 2). It was more obvious with higher flow density on the vessel density map (fig. 2 white circle). With 3D reconstruction of the angiography, the morphology of the macroaneurysm and the spatial relationship with the retinal vessels could be vividly observed (gif. red arrow). A TowardPi full range SS-OCTA #YAlkaid was used in this case to acquire comprehensive structural and flow information of the retinal macroaneurysm. Thickness map and flow density can be quantified on the device. Structure and flow can both be reconstructed in three-dimension for further exploration of diseases.
