From: Human amniotic membrane plug to promote failed macular hole closure
Adaptive optics and microperimetry results. (a) A 6-month postoperative structural OCT shows macular hole closure and the subretinal hAM plug (red arrow). (b) Images from the Rtx1 adaptive optics (AO) fundus camera: the red square represents the area investigated using the Rtx1 AO fundus camera. The red arrows indicate the edge of the patch. The magnified image of the area indicates some bright dots corresponding to photoreceptors. (c) The automatically-processed zone (red square in fig. b) of the AO image shows the photoreceptors (blue cross) detected by the Rtx1 software. (d) Retinal sensitivity map obtained using microperimetry: a central small area of absolute scotoma (red circles) corresponds to a lack of sensitivity, while a surrounding wider area of the relative scotoma (orange and yellow circles) indicates a preservation of retinal sensitivity over the hAM plug.
