“…Previous researches reported common signs of FA findings in PURs including areas of non-perfusion, retinal ischemia and slower filling of vessels[2]. OCT-A may reveal extensive nonperfusion in the macular area in both inner and deep capillary plexus[5,6]. This patient also presented a hypoperfusion condition in retina layer.…”

Background To report a case of Purtscher-like retinopathy (PUR) and his optical coherence tomography (OCT) and OCT-angiography (OCT-A) findings before and after treatment. Case presentation A 65-year-old male presented with acute onset of vision loss for 2 weeks. Fundus examination revealed cotton-wool spots, retinal hemorrhage, and purtscher flecken spreading around the optic disc in the right eye. He was diagnosed with Purtscher-like retinopathy because of the absent reports of any traumatic medical history. OCT presented some band-like hyperreflective lesions at the layer of inner nuclear layer known as paracentral acute middle maculopathy (PAMM). OCT-A revealed apparent reduction of blood flow signal at the layers of deep retina and choriocapillaris with a pattern of honeycomb-like hypointense signal. After 3-month follow-up, OCT scan showed a resolution of retinal edema, but the PAMM lesions were still visible. OCT-A presented the honeycomb-like pattern turned into a homogeneous reduction of blood flow with small patches of hypointense signal areas in choriocapillaris. Conclusion This case presented a new OCT-A sign in Purtscher-like retinopathy with a honeycomb-like hypointense signal at the layer of choriocapillaris indicates the involvement and the ischemia condition of the choroid in its pathological process.

Background: To report a case of Purtscher-like retinopathy (PUR) and the optical coherence tomography (OCT) and OCT angiography (OCT-A) findings before and after treatment. Case presentation: A 65-year-old male presented with acute onset of vision loss for 2 weeks. Fundus examination revealed cotton-wool spots, retinal haemorrhage, and Purtscher flecken spread around the optic disc in the right eye. He was diagnosed with Purtscher-like retinopathy because he lacked any traumatic medical history. OCT presented some band-like hyperreflective lesions at the inner nuclear layer, which are indicative of paracentral acute middle maculopathy (PAMM). OCT-A revealed apparent reduction in blood flow signal at the deep retina and choriocapillaris layers with a honeycomb-like hypointense signal pattern. After 3 months of follow-up, OCT revealed resolution of retinal oedema, but PAMM lesions remained visible. Based on OCT-A, the honeycomb-like pattern turned into a homogeneous reduction in blood flow with small patches of hypointense signal areas in the choriocapillaris. Conclusion: This case presented a new OCT-A sign in PUR with a honeycomb-like hypointense signal at the choriocapillaris layer, indicating the involvement and ischaemia of the choroid during the pathological process.

The most common ocular manifestation following electric shock injury is the development of cataract. Retinal manifestations can vary from development of macular holes to retinal detachments. Purtscher-like retinopathy following electrical injury has not been reported till date. We hereby present a case of a 19-year-old electrician who presented with grossly reduced vision in the right eye of 2 months following an electric shock. The fundus of the right eye showed macular ischemic degeneration, occluded vessels, cotton-wool spots, and hemorrhages. Optical coherence tomography angiography revealed presence of capillary drop-out in the para-foveal region, which was more pronounced in the deep capillary plexus. Electric shock injury can lead to a clinical picture simulating Purtscher's retinopathy. The electrical injury leads to a more extensive damage to the deep capillary plexus as compared with the superficial plexus.
