Clinical features of three-layer’s impairment of capillary plexuses’ perfusion at follow-up in patients with Purcher retinopathy and Purcher-like retinopathy

Abstract

In Purcher retinopathy and Purcher-like retinopathy, ischemic lesions occur at the level of all three retina capillary plexuses. Recognition of characteristic ischemic patterns by optical coherence tomography helps to predict the degree of visual functions’ recovery. The aim of this study is to present clinical cases of patients with Purcher retinopathy and Purcher-like retinopathy and to observe the dynamics of visual rehabilitation of patients with retinal vascular conditions. Two patients with complaints of central vision loss and skotomata in the visual field were examined. The complex of multimodal visualization included fundus photoregistration with fundus camera, optical coherence tomography and optical coherence tomography-angiography, and microperimetry. Paracentral acute middle maculopathy and acute macular neuroretinopathy are the manifestations of the same ischemic process on different levels of retinal vascular plexuses. The “diffuse” pattern damages in paracentral acute middle maculopathy lead to more permanent structural and functional impairments opposed to the “skip” pattern. The optical coherence tomography allows to predict the possibilities of visual and functional rehabilitation in patients with ischemic damage of retinal vessels.
