Bilateral acute macular neuroretinopathy associated with COVID-19 infection presenting with central scotoma.

Purpose: To report a case of bilateral acute macular neuroretinopathy (AMN) associated with COVID-19 infection presenting with central scotoma. Observation: A 26-year-old female presented with a chief complaint of bilateral central scotomas for the last seven days. She had a history of fever over the past ten days, and RT-PCR test for COVID-19 was positive on the second day of fever. She had been vaccinated against COVID-19 eight months prior. Her best corrected visual acuity was 6/6 in both eyes on the Snellen chart. Dilated fundus evaluation revealed subtle bilateral perifoveal grey macular lesions. Optical coherence tomography (OCT) demonstrated focal hyperreflectivity at the level of the outer nuclear and plexiform layer consistent with bilateral AMN. Near-infrared reflectance (NIR) and red-free (RF) imaging showed large, confluent hyporeflective lesions in the right eye and discrete petaloid lesions with apices pointing toward the fovea in the left eye. OCT angiography (OCTA) revealed decreased flow signal at the level of the deep capillary plexus (DCP) and choriocapillaris (CC) in both eyes. Automated visual field testing (Humprey Field Analyzer (HFA) 24-2) revealed bilateral central scotoma with depression of adjacent points. After two weeks, the patient had depressed visual fields on HFA 10-2. At two months of final follow-up, OCT macula, NIR and RF images revealed resolving AMN lesions in both eyes. OCTA showed an increase in perfusion at the level of the DCP. There was a decrease in scotoma density on HFA 10-2, suggestive of resolving AMN. Conclusion and importance: AMN with central scotoma as presenting feature of COVID-19 is rare. Fundus findings may be very subtle in AMN, but NIR and RF imaging delineate the lesions well. OCT, NIR imaging, OCTA and HFA 10-2 can be used to assess the clinical course of AMN.

Unveiling the metabolic and coagulation disruptions in SARS-CoV-2-associated acute macular neuroretinopathy: A case-control study.

SARS-CoV-2 infection has been associated with the increased incidence of acute macular neuroretinopathy (AMN), an infrequent ocular disorder. However, the precise mechanisms underpinning AMN in the context of SARS-CoV-2 infection (AMN-SARS-CoV-2) remain elusive. In this case-control study, 14 patients diagnosed with AMN-SARS-CoV-2 between 2022/12 and 2023/3 were enrolled and compared with 14 SARS-CoV-2-infected individuals without AMN, who served as controls (SARS-CoV-2-no AMN). Metabolomic profiling using ultrahigh-performance liquid chromatography-online electrospray mass spectrometry revealed significant alterations in serum metabolites in AMN-SARS-CoV-2 patients. Coagulation abnormalities were observed in AMN-SARS-CoV-2 patients, and their relationship with metabolic disorders was studied. Finally, a predictive model for AMN-SARS-CoV-2 was established. Seventy-six upregulated and 42 downregulated metabolites were identified in AMN-SARS-CoV-2 cases. Notably, arginine metabolism within the urea cycle was significantly altered, evidenced by variations in ornithine, citrulline,  l-proline, and ADAM levels, correlating with abnormal coagulation markers like platelet crit, fibrinogen degradation product, and fibrinogen. Additionally, increased arginase 1 (AGR1) activity within the urea cycle and reduced nitric oxide synthase activity were observed in AMN-SARS-CoV-2. The integration of urea cycle metabolite levels with coagulation parameters yielded a robust discriminatory model for AMN-SARS-CoV-2, as evidenced by an area under the curve of 0.96. The findings of the present study enhance our comprehension of the underlying metabolic mechanisms associated with AMN-SARS-CoV-2 and offer potential diagnostic markers for this uncommon ocular disorder within the context of SARS-CoV-2 infection.

Multicenter and multimodal imaging study reveals rare fundus lesions in patients after SARS-CoV-2 infection.

To define the characteristics of fundus manifestations in patients after SARS-CoV-2 infection with multimodal imaging techniques. This is a retrospective multicenter and multimodal imaging study including 90 patients. All patients with a visual complaint occurring immediately after SARS-CoV-2 infection were referred to six clinics between December 2022 and February 2023. Demographic information and the temporal relationship between SARS-CoV-2 infection and visual symptoms were documented. The characteristics of the fundus lesions were evaluated using multimodal imaging. Ninety patients from six hospitals were included in this study, including 24 males (26.67%) and 66 (73.33%) females. Seventy-eight patients (86.66%) (146 eyes) were diagnosed with Acute Macular Neuroretinopathy (AMN). The AMN patients were primarily young women (67.95%). Sixty-eight patients (87.18%) had AMN in both eyes. Thirty-eight eyes (24.36%) included Purtscher or Purtscher-like lesions. optical coherence tomography and infrared retinal photographs can show AMN lesions well. Eleven cases were diagnosed with simple Purtscher or Purtscher-like retinopathy (2 cases, 2.22%), Vogt‒Koyanagi‒Harada (VKH) syndrome or VKH-like uveitis (3 cases, 3.33%), multiple evanescent white-dot syndrome (MEWDS) (2 cases, 2.22%), and rhino-orbital-cerebral mucormycosis (ROCM) (5 cases, 5.56%). After SARS-CoV-2 infection, diversified fundus lesions were evident in patients with visual complaints. In this report, AMN was the dominant manifestation, followed by Purtscher or Purtscher-like retinopathy, MEWDS, VKH-like uveitis, and ROCM.

Case report: dengue fever associated acute macular neuroretinopathy.

Dengue fever (DF), which is caused by the dengue virus (DENV) and transmitted through Aedes mosquitoes, is well recognized for its systemic manifestations, with its ocular involvement gaining recent attention. We present a case of a 41-year-old Taiwanese female who developed acute macular neuroretinopathy (AMN) following a DF diagnosis related to DENV-1, emphasizing the need for awareness of this complication. The patient, with a history of completely resolved optic neuritis (ON) and comorbidities, experienced blurred vision on day 10 after the onset of DF. The ophthalmic examination revealed macular edema, ellipsoid zone (EZ) infiltration, and choriocapillaris involvement. Despite pulse therapy with corticosteroids, visual disturbances persisted, highlighting the challenge of managing ocular complications. Ocular manifestations in DF include hemorrhages, inflammation, and vascular complications. DF-associated AMN, a rare presentation, poses challenges in diagnosis and treatment response evaluation. While most patients recover spontaneously, some face persistent visual impairment, especially with AMN. Our case emphasizes the importance of recognizing ocular complications in DF, necessitating a multidisciplinary approach for optimal management and further research to delineate treatment strategies and outcomes.

Optical coherence tomography angiography suggests choriocapillaris perfusion deficit as etiology of acute macular neuroretinopathy.

PURPOSE: Acute macular neuroretinopathy (AMN) can cause sudden-onset and permanent scotoma in healthy young patients. Analysis of optical coherence tomography (OCT) and OCT angiography (OCTA) of AMN patients may provide insights into disease mechanism. METHODS: We conducted a retrospective study of consecutive SARS-Cov-2-related AMN patients that presented in our clinic between Jan 1st, 2022, and April 30th, 2023, within 30 days of symptom onset. Retinal vessel area density (VAD) of AMN lesions in OCTA was quantified and compared to an adjacent tissue control (ATC). This quantification was performed for the superficial vascular plexus (SVP), the intermediate capillary plexus (ICP), the deep capillary plexus (DCP), the choriocapillaris (CC), and choroid. Furthermore, en face OCT images were analyzed. RESULTS: Nine AMN patients were identified, 6 of these (4 female, 2 male, average age 25 years) fulfilled the inclusion criteria and were included into this study. Average time from symptom onset to OCTA was 14.3 days. No VAD differences between AMN and adjacent tissue were found in either retinal layer (SVP, ICP, DCP). In contrast, VAD in CC was reduced by 27% against the ATC (p = 0.007) and choroidal VAD was reduced by 41% (p = 0.017). Further analysis of en face OCT could show that the pathognomonic infrared hyporeflectivity in AMN is caused by photoreceptor alterations rather than changes in the inner retinal layers. CONCLUSIONS: Our data suggests that a perfusion deficit in the choroidal layers is responsible for AMN rather than in the DCP, which is the predominant hypothesis in current literature.

Clinical Spectrum of Ophthalmic Manifestations in Myelin Oligodendrocyte Glycoprotein-Associated Disease (MOGAD): A Comprehensive Case Report.

PURPOSE: To describe diverse ocular manifestations in a patient with Myelin oligodendrocyte glycoprotein-associated disease (MOGAD). METHODS: A 15-year-old Indian male had severe loss of vision in one eye, followed by a recurrent attack of optic neuritis in the fellow eye a few weeks later. He had a history of vision loss, speech disturbances, altered sensorium and was a confirmed case of Myelin oligodendrocyte glycoprotein-associated disease (MOGAD). Apart from optic neuritis, other rare ophthalmic associations, namely, macular neuroretinopathy, retinal haemorrhages, severe optic nerve head edema, peri neuritis, and orbital enhancement on magnetic resonance imaging (MRI) were noted. RESULTS: He responded dramatically to treatment with intravenous pulse steroids and relapses were controlled with long-term immunomodulation therapy. CONCLUSION: This case report reiterates the need for early treatment with pulse steroids in MOGAD and depicts the heterogeneous involvement of various ocular structures in the disease.

Acute macular neuroretinopathy and COVID-19 or SARS-CoV-2 infection: case report and literature review.

Purpose: To describe a case of acute macular neuroretinopathy (AMN) associated with COVID-19 infection and a related literature review. Methods: A case from the First Affiliated Hospital of Chongqing Medical University was reported that could be linked to COVID-19 or SARS-CoV-2 infection. We performed a comprehensive search on PubMed, retrieving articles containing information on AMN after COVID-19 or SARS-CoV-2 infection. The key words used were 'COVID-19', 'SARS-CoV-2', 'ophthalmic manifestations', 'acute macular neuroretinopathy', and 'paracentral scotomas'. The relevant data were extracted, charted, consolidated, and evaluated. Moreover, manual exploration of the reference lists of pertinent articles was carried out. Results: We describe the case of a 30-year-old young woman who developed bilateral AMN one day after being infected with COVID-19 or SARS-CoV-2. She had severe visual impairment (20/2000 OD and 20/32 OS), and her vision recovered after taking oral corticosteroids. After reviewing the literature, we summarized 16 relevant reports and found that symptoms of AMN tend to arise 1 day to 1 month after COVID-19 or SARS-CoV-2 infection. Contraceptive pills and other risk factors should be avoided to reduce the risk of adverse outcomes. Oral prednisone may be an effective treatment for those experiencing important vision loss. Conclusion: Symptoms of AMN can arise 1 day to 1 month after COVID-19 or SARS-CoV-2 infection. Ophthalmologists should remain vigilant about this disease, notably because patient characteristics may deviate from the norm.

The characteristics of acute macular neuroretinopathy following COVID-19 infection.

BACKGROUND: In this study, we report a case series of acute macular neuroretinopathy (AMN) associated with COVID-19 infection. METHODS: This retrospective observational study was conducted at Beijing Tongren Hospital. We reviewed patients who were diagnosed with AMN within one month of testing positive for COVID-19 using real-time reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: A total of 11 AMN patients (20 eyes) were included in the study. The mean age was 33.8 ± 12.6 years. The average interval between a positive COVID-19 PCR test and the onset of ocular symptoms was 2.8 ± 2.5 days. The mean follow-up period for the patients was 12.5 ± 3.8 weeks. Imaging characteristics of AMN patients following COVID-19 infection included areas of low reflectivity on near-infrared reflectance (NIR) imaging, hyperreflective lesions at the level of the outer plexiform layer (OPL) and outer nuclear layer (ONL) and disruption of the ellipsoid zone (EZ) on spectral domain optical coherence tomography (SD-OCT) B-scans. Visual field examinations revealed parafoveal scotomas that closely corresponded to the clinical lesions. Optical coherence tomography angiography (OCT-A) demonstrated impaired perfusion in the deep retinal vascular plexus. Fluorescein angiography (FA), indocyanine green angiography (ICGA), and spontaneous fundus autofluorescence showed no significant abnormalities. During follow-up, partial improvement in retinal lesions was observed in NIR imaging and SD-OCT in some patients, but a proportion of patients still exhibited persistent retinal damage and no improvement in visual field scotomas. CONCLUSION: COVID-19-related AMN share similar clinical and imaging features with AMN due to other causes, as evidenced by the persistent presence of visual field scotomas over a longer duration.

Case Report: Acute Macular Neuroretinopathy Which Led to COVID-19 Infection Diagnosis.

We present a case of Acute Macular Neuroretinopathy (AMN), which led to the coronavirus disease of 2019 (COVID-19) infection diagnosis. A 27-year-old female patient with flu-like symptoms later proven to be COVID-19 infection presented with acute-onset bilateral gray-like paracentral scotomas. Fundus examination showed a hypopigmented, wedge-like lesion on the superior temporal juxtafoveal area in the right eye, while no significant finding was found in the left eye. Infrared reflectance images demonstrated bilateral hyporeflective lesions in the parafoveal regions of the macula. Spectral-domain optical coherence tomography scans over the corresponding areas detected focal hyperreflectivity in the outer nuclear layer with disruption in the ellipsoid zone and retinal pigment epithelium layers. Based on these findings, the AMN diagnosis was considered. The COVID-19 infection diagnosis was confirmed by a polymerase chain reaction test. COVID-19 disease may cause retinal vascular complications such as AMN. AMN, which shares common viral prodromal symptoms with COVID-19 infection, may be a presenting sign of COVID-19 infection.

Maculopatía paracentral aguda media y neurorretinopatía macular aguda / Paracentral Acute Middle Maculopathy and Acute Macular Neuroretinopathy

La neurorretinopatía macular aguda es una condición rara con patogenia microvascular. Se presenta con un inicio agudo con escotomas paracentrales correspondientes a lesiones paramaculares evidentes. Los avances en las imágenes multimodales permitieron caracterizar este trastorno de retina y crear nuevos conceptos. Serraf, en el 2013, identificó dos formas por medio de la tomografía de coherencia óptica dominio espectral: el tipo 1 conocido como maculopatía paracentral aguda media en la cual se observa una banda hiperreflectiva en la capa nuclear interna, y el tipo 2 en el cual la banda hiperreflectiva se ubica en la capa nuclear externa, que involucra la zona elipsoide y la zona de interdigitación con el epitelio pigmentario de la retina. Hasta el momento no existe cura; pero se puede actuar sobre los factores de riesgo. Por ser una condición rara y por no existir reportes hasta el momento en Cuba es que se presentan a continuación dos pacientes con cuadros clínicos similares de estas dos variantes; concluyendo la importancia que presentan las imágenes multimodales como medio auxiliar diagnóstico(AU)

Acute macular neuroretinopathy is a rare condition with complex pathogenesis and microvascular cause. It appears with acute onset, with paracentral scotomas corresponding to obvious paramacular lesions. Advances in multimodal imaging made it possible to characterize this retinal disorder and to create new concepts. Serraf, in 2013, identified two forms by spectral domain optical coherence tomography: type 1, known as paracentral acute middle maculopathy, in which a hyperreflective band is observed in the inner nuclear layer; and type 2, in which the hyperreflective band is located in the outer nuclear layer, involving the ellipsoid zone and the zone of interdigitation with the retinal pigment epithelium. Up to this moment, there is no cure; but it is possible to act on the risk factors. Because it is a rare condition and because there are no reports so far in Cuba, two patients with similar clinical pictures of these two variants are presented; concluding the importance of multimodal images as an auxiliary diagnostic tool(AU)

Acute Macular Neuroretinopathy after SARS-CoV-2 Infection: An Analysis of Clinical and Multimodal Imaging Characteristics.

BACKGROUND: This study aimed to analyze clinical and multimodal imaging characteristics of acute macular neuroretinopathy (AMN) post-recent severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: Retrospective observational study. Medical records and multimodal imaging of 12 AMN eyes of eight patients (six female and two male) with recent SARS-CoV-2 infection were retrospectively analyzed. RESULTS: Four patients (50%) presented with bilateral AMN. Fundus ophthalmoscopy revealed a reddish-brown lesion around the macula, and two eyes had cotton-wool spots at the posterior pole. Three eyes showed mild hypo-autofluorescence. All FFA images (7 eyes) showed no abnormal signs. On OCT scans, all eyes showed outer nuclear layer (ONL) thinning, 8 eyes (66.7%) showed ONL hyperreflectivity, 5 eyes (41.7%) showed outer plexiform layer (OPL) hyperreflectivity, 8 eyes (66.7%) showed interdigitation zone (IZ) disruption, 11 eyes (91.6%) showed ellipsoid zone (EZ) disruption, 2 eyes (16.7%) showed cotton-wool spots and inner plexiform layer (IPL) hyperreflectivity, 1 eye (8.3%) had intraretinal cyst and 1 eye (8.3%) had inner nuclear layer (INL) thinning. Persistent scotoma, ONL hyperreflectivity and IZ/EZ disruption as well as recovery of OPL hyperreflectivity were reported after follow-up in three cases. CONCLUSIONS: AMN post-SARS-CoV-2 mostly affected young females and could present unilaterally or bilaterally. Dark lesions on IR reflectance and outer retinal hyperreflectivity on OCT are useful in diagnosing AMN. OPL/ONL hyperreflectivity on OCT could disappear after follow-up, but ONL thinning and IZ/EZ could persist.

Long-term follow-up of a young male who developed acute macular neuroretinopathy following COVID-19 vaccination.

This report presents the clinical findings and prognosis of a healthy male patient who developed acute macular neuroretinopathy after COVID-19 vaccination. Abnormal findings improved about 1 month after the onset and disappeared 3 months later. The subjective symptoms disappeared in 3 months, and no recurrence was observed for 1 year.

Choroidal Circulatory and Vascular Morphological Changes in Acute Macular Neuroretinopathy After Infection With Severe Acute Respiratory Syndrome Coronavirus 2: A Case Report With Literature Review.

BACKGROUND/AIM: The aim of this study was to analyze choroidal circulatory and structural changes using laser speckle flowgraphy (LSFG) and optical coherence tomography (OCT) in acute macular neuroretinopathy (AMN) after infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), respectively. CASE REPORT: A 24-year-old woman complained of distorted vision after SARS-CoV-2 infection oculi uterque (OU) and referred to our hospital because of ellipsoid zones (EZ) disruption on OCT. Her best-corrected visual acuity (BCVA) was 1.2 OU. Color fundus photographs revealed dark red lesions in the macula, and scanning laser ophthalmoscopy infrared images showed hypointensity consistent with dark red lesions OU. We diagnosed the patient with AMN after SARS-CoV-2 infection, and posterior sub-Tenon injections of triamcinolone acetonide were performed OU. Five months after the initial visit, her BCVA was 1.2 OU, and EZ disruption improved. The rate of change in macular blood flow assessed by the mean blur rate on LSFG was 20.4% and 29.6% increase oculus dexter (OD) and oculus sinister (OS) 5 months after the initial visit, respectively. The central choroidal thickness showed 13.5% increase OD and 16.1% increase OS. The binarization technique demonstrated that the ratio of luminal areas in choroidal area increased by 12.6% OD and 14.2% OS, and stromal areas increased by 7.3% OD and 16.9% OS. CONCLUSION: Before and after treatment for AMN, the luminal component may have increased with improvement of acute choroidal circulatory disturbance caused by SARS-CoV-2, and increased stromal components may be due to chronic inflammation and tissue remodeling of the stroma.

Concomitant paracentral acute middle maculopathy and acute macular neuroretinopathy in eyes post-blunt trauma.

Purpose: To analyze the imaging characteristics and the clinical course of patients showing concomitant paracentral acute middle maculopathy (PAMM) and acute macular neuroretinopathy (AMN) post-blunt trauma. Methods: PAMM and AMN lesions post-blunt trauma diagnosed on enhanced depth imaging optical coherence tomography (EDI-OCT) were recruited for the study. Results: : Thirteen eyes of 13 individuals with a history of blunt trauma were included in the study, of whom 11 (85%) were males. Mean age of the patients was 33.62 (range 16-67) years. Mean visual acuity at presentation and the last visit was 1.67 log of minimum angle of resolution (logMAR) and 0.82 logMAR, respectively. Mean interval between trauma and imaging was 5.08 (range 1-15) days. All patients had unilateral involvement, with the right eye being involved in 10 patients (77%). All patients had concomitant PAMM and AMN lesions. Conclusion: : Presence of coincident PAMM and AMN suggests a common pathophysiologic etiology, but the description of concomitant PAMM and AMN in the setting of blunt trauma to eye is hitherto unreported. Identifying AMN in a setting of PAMM requires meticulous examination of the OCT and OCTA images. It can be a cause of suboptimal visual recovery in such eyes.

Acute macular neuroretinopathy following Moderna COVID-19 vaccination.

PURPOSE: To describe the occurrence of an acute macular neuroretinopathy (AMN) after administration of a Moderna COVID-19 Vaccine. METHODS: Case report. RESULTS: A 23-year-old female presented bilateral visual loss one week after the first dose of COVID-19 vaccine. Fundus examination revealed the classic wedge-shaped lesions with petaloid configuration around both foveas. Hypo-reflective macular lesions are evident in the near-infrared reflectance image. The spectral-domain optical coherence tomography reveled hyperreflectivity of the outer nuclear and plexiform layers, attenuation of the ellipsoid zone and disruption of interdigitation zone corresponding to the lesions. CONCLUSIONS: Despite the large number of doses of COVID-19 vaccines administered worldwide, there are not many reported cases of AMN. Most of them occurred after viral vector vaccines. Described here is one of the few cases that observed a time period of several days after receiving the Moderna messenger RNA vaccine. It is not possible to establish causality although this suggests an inflammatory or autoimmune response to the vaccine.

A Case of Concurrent Acute Macular Neuroretinopathy and Paracentral Acute Middle Maculopathy Following Pfizer-BioNTech COVID-19 Vaccination.

We present a 65-year-old woman who developed sudden and severe vision loss in her left eye one day after the administration of the second dose of COVID vaccine. The best corrected visual acuity in this eye was 1/10. Diffuse paracentral acute middle maculopathy was detected on spectral domain optical coherence tomography (OCT). OCT angiography images revealed concurrent vascular flow defects consistent with acute macular neuroretinopathy in the deep retinal capillary plexus and choriocapillaris layers. At the end of the six-month follow-up, there was no improvement in visual acuity, and atrophy and thinning developed in all layers of the retina.

BILATERAL ACUTE MACULAR NEURORETINOPATHY IN ACUTE COVID-19 INFECTION: A CASE STUDY.

AIM: The aim of the present paper is to describe the case study of a female patient with bilateral AMN, suffering from active acute infection with COVID-19. METHODS: A 32-year-old female patient with impaired vision bilaterally persisting for 2 days reported to the emergency Department of Ophthalmology at the Central Military Hospital in Ruzomberok, Slovakia. The patient manifested symptoms of COVID-19 infection persisting for 3 days before the onset of visual complaints. RESULTS: At the primary examination, initial best corrected central visual acuity was 20/40 bilaterally, paracentral scotomas were present more in the right eye. Upon examination of the ocular fundus, the edges of the optic nerve disc were out of focus more in the left eye; brownish red petaloid lesions were present around the fovea, the periphery was without pathological findings. OCT and OCTA were performed, with a conclusion of bilateral AMN upon a background of COVID-19 infection. Low molecular weight heparin (LMWH) was administered in a preventive dose. CONCLUSION: The number of documented ocular complications of COVID-19 infection, including microvascular events, is currently increasing.

Clinical and multimodal imaging features of acute macular neuroretinopathy lesions following recent SARS-CoV-2 infection.

AIM: To describe the clinical characteristics of eyes using multimodal imaging features with acute macular neuroretinopathy (AMN) lesions following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. METHODS: Retrospective case series study. From December 18, 2022 to February 14, 2023, previously healthy cases within 1-week infection with SARS-CoV-2 and examined at Tianjin Eye Hospital to confirm the diagnosis of AMN were included in the study. Totally 5 males and 9 females [mean age: 29.93±10.32 (16-49)y] were presented for reduced vision, with or without blurred vision. All patients underwent best corrected visual acuity (BCVA), intraocular pressure, slit lamp microscopy, indirect fundoscopy. Simultaneously, multimodal imagings fundus photography (45° or 200° field of view) was performed in 7 cases (14 eyes). Near infrared (NIR) fundus photography was performed in 9 cases (18 eyes), optical coherence tomography (OCT) in 5 cases (10 eyes), optical coherence tomography angiography (OCTA) in 9 cases (18 eyes), and fundus fluorescence angiography (FFA) in 3 cases (6 eyes). Visual field was performed in 1 case (2 eyes). RESULTS: Multimodal imaging findings data from 14 patients with AMN were reviewed. All eyes demonstrated different extent hyperreflective lesions at the level of the inner nuclear layer and/or outer plexus layer on OCT or OCTA. Fundus photography (45° or 200° field of view) showed irregular hypo-reflective lesion around the fovea in 7 cases (14 eyes). OCTA demonstrated that the superficial retinal capillary plexus (SCP) vascular density, deep capillary plexus (DCP) vascular density and choriocapillaris (CC) vascular density was reduced in 9 case (18 eyes). Among the follow-up cases (2 cases), vascular density increased in 1 case with elevated BCVA; another case has vascular density decrease in one eye and basically unchanged in other eye. En face images of the ellipsoidal zone and interdigitation zone injury showed a low wedge-shaped reflection contour appearance. NIR image mainly show the absence of the outer retinal interdigitation zone in AMN. No abnormal fluorescence was observed in FFA. Corresponding partial defect of the visual field were visualized via perimeter in one case. CONCLUSION: The morbidity of SARS-CoV-2 infection with AMN is increased. Ophthalmologists should be aware of the possible, albeit rare, AMN after SARS-CoV-2 infection and focus on multimodal imaging features. OCT, OCTA, and infrared fundus phase are proved to be valuable tools for detection of AMN in patients with SARS-CoV-2.
