Paracentral acute middle maculopathy following SARS-CoV-2 infection: the D-dimer hypothesis.
TLDR
In this paper, a case of bilateral acute-onset scotoma following SARS-CoV-2 infection in a 19-year-old girl attributed to the presence of paracentral acute middle maculopathy (PAMM).Abstract:
We herein report a case of bilateral acute-onset scotoma following SARS-CoV-2 infection in a 19-year-old girl attributed to the presence of paracentral acute middle maculopathy (PAMM). She was tested positive for SARS-CoV-2 infection 2 weeks prior by reverse transcription PCR testing andread more

COVID-19-Related Retinal Micro-vasculopathy – A Review of Current Evidence
TL;DR: In this article , a systematic review and meta-analysis was conducted to evaluate the occurrence of retinal microvasculopathy in patients infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and who developed CoV-19.

Retinal and choroidal manifestations of COVID-19.
TL;DR: The posterior segment involvement of COVID-19 has been discussed in this paper, showing that most of the retinal findings are a result of microvascular derangement leading to cotton wool spots, intra-retinal hemorrhages, paracentral acute middle maculopathy, acute macular neuroretinopathy, or retinal vein occlusions.

Acute macular neuroretinopathy as a manifestation of coronavirus disease 2019: A case report.
TL;DR: In this article, the authors raise clinicians' awareness of the possibility of coincident acute macular neuroretinopathy (AMN) and COVID-19 as a potential cause of retinal vascular damage and ischemia.

Sub-internal limiting membrane haemorrhage as a manifestation of transiently deranged coagulation profile following SARS-CoV-2 infection
TL;DR: A case of unilateral acuteonset transient selfresolving central visual loss following SARSCoV2 infection in a 41yearold man attributed to the presence of subinternal limiting membrane (ILM) haemorrhage, which is linked to the disease severity and high mortality in such patients.

TL;DR: Successful revascularization was lower than expected which the authors hypothesize is due to a virus-related hypercoagulable state and the use of prolonged systemic heparin may improve surgical treatment efficacy as well as improve limb salvage and overall mortality.

TL;DR: Paracentral acute middle maculopathy may represent a novel variant of AMN that affects the middle layers of the macula above the OPL as diagnosed with SD-OCT imaging and it is proposed that each of these lesions may be explained by occlusion of either the superficial capillary plexus or deep capillaryplexus located in the innermost and outermost portion of the INL.
