[PMID: 38827998 PMCID: PMC11141142 DOI: 10.1016/j.ajoc.2024.102001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Revised: 10/23/2023] [Accepted: 01/22/2024] [Indexed: 06/05/2024] Open
Abstract
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.

Abstract
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.

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. In Vivo 2023; 37:2869-2876. [PMID: 37905626 PMCID: PMC10621410 DOI: 10.21873/invivo.13405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 08/21/2023] [Accepted: 08/25/2023] [Indexed: 11/02/2023]
Abstract
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.

Clinical and Diagnostic Findings of Acute Macular Neuroretinopathy and Paracentral Acute Middle Maculopathy in the COVID-19 Era. Ophthalmologica 2023; 246:181-191.

Abstract
BACKGROUND Growing evidence suggests an association between the infection from the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) and eye disorders. The aim of this review was to analyze the clinical presentation and diagnostic features of acute macular neuroretinopathy (AMN) and paracentral acute middle maculopathy (PAMM) associated with COVID-19 infection. The features are then compared with previous reports regarding these retinal disorders, to recognize possible specific characteristics and to assess the role of multimodal ophthalmic imaging. SUMMARY A literature search was performed by consulting PubMed, Scopus, and Embase. The following terms were searched: "(COVID-19 OR SARS-CoV-2 OR coronavirus) AND ([acute macular neuroretinopathy] OR [paracentral acute middle maculopathy])." Inclusion criteria were as follows: (1) publication date from January 31, 2020 to January 31, 2022; (2) English language; (3) original research or case report; (4) free full-text availability.Optical coherence tomography (OCT) findings in AMN patients were hyper-reflectivity (HR) of the outer plexiform layer, of the outer nuclear layer, and ellipsoid or interdigitation zones (EZ and IZ, respectively) disruption. In most cases, the presence of HR and EZ/IZ abnormalities resulted combined. When performed, OCT angiography (OCTA) identified attenuation of signal of the deep capillary plexus (DCP). The most common OCT finding in PAMM was an alteration of the inner nuclear layer, associated with other areas of HR, while no signs of EZ/IZ disruption were detected. When performed, OCTA showed the attenuation of signal of both the DCP and the superficial capillary plexus. KEY MESSAGES In this review, we reported a case series of AMN and PAMM in patients with a previous or concomitant infection from SARS-CoV-2. The microvascular changes in these cases are highlighted by the OCTA scans. Even if we are far from the determination of a direct link between COVID-19 and these retinal disorders, we could hypothesize that the vascular alterations associated with SARS-CoV-2 infection could be a possible risk factor for both AMN and PAMM.

Abstract
Purpose: To review the demographic and clinical profile of patients developing acute macular neuroretinopathy (AMN) or paracentral acute middle maculopathy (PAMM) after receiving coronavirus disease-2019 (COVID-19) vaccination or infection. Methods: In this review article, the published literature was searched to determine cases developing either AMN or PAMM after COVID-19 vaccinations or infections. Data, including demographic profile, presenting features, symptoms, diagnosis, and clinical outcomes, were extracted from the selected publications. These parameters were compared between the two groups, i.e., patients developing AMN/PAMM either after vaccination or infection. Results: After the literature review, 57 patients developing either AMN (n = 40), PAMM (n = 14), or both (n = 3) after COVID-19 infection (n = 29) or vaccination (n = 28) were included (mean age: 34.9 ± 14.4 years; n = 38; 66.7% females). In 24.6% patients, the diagnosis of COVID-19 infection was preceded by the development of ocular disease. There were no significant differences in the age or gender between the patients developing AMN or PAMM after vaccination or infection (p > 0.13). Among the vaccination group, the highest number of patients developing AMN/PAMM were after the Oxford-AstraZeneca (n = 12; 42.9%). Patients with vaccination had a significantly early onset of AMN/PAMM compared to those with infection (11.5 ± 17.6 days versus 37.8 ± 43.6 days; p = 0.001). Conclusions: Both AMN and PAMM are reported to be associated with COVID-19 infections and in persons receiving vaccination against COVID-19. While COVID-19 infections and vaccinations may have a contributory role, other risk factors such as oral contraceptive pills may also play a role in the development of the disease.

Non-invasive brain microcurrent stimulation therapy of long-COVID-19 reduces vascular dysregulation and improves visual and cognitive impairment. Restor Neurol Neurosci 2021; 39:393-408.

Abstract
BACKGROUND An effective treatment is needed for long-COVID patients which suffer from symptoms of vision and/or cognition impairment such as impaired attention, memory, language comprehension, or fatigue. OBJECTIVE Because COVID-19infection causes reduced blood flow which may cause neuronal inactivation, we explored if neuromodulation with non-invasive brain stimulation using microcurrent (NIBS), known to enhance blood flow and neuronal synchronization, can reduce these symptoms. METHODS Two female long-COVID patients were treated for 10-13 days with alternating current stimulation of the eyes and brain. While one patient (age 40) was infected with the SARS CoV-2 virus, the other (age 72) developed symptoms following AstraZeneca vaccination. Before and after therapy, cognition was assessed subjectively by interview and visual fields quantified using perimetry. One patient was also tested with a cognitive test battery and with a retinal dynamic vascular analyser (DVA), a surrogate marker of vascular dysregulation in the brain. RESULTS In both patients NIBS markedly improved cognition and partially reversed visual field loss within 3-4 days. Cognitive tests in one patient confirmed recovery of up to 40-60% in cognitive subfunctions with perimetry results showing stable and visual field recovery even during follow-up. DVA showed that NIBS reduced vascular dysregulation by normalizing vessel dynamics (dilation/constriction), with particularly noticeable changes in the peripheral veins and arteries. CONCLUSIONS NIBS was effective in improving visual and cognitive deficits in two confirmed SARS-COV-2 patients. Because recovery of function was associated with restoration of vascular autoregulation, we propose that (i) hypometabolic, "silent" neurons are the likely biological cause of long-COVID associated visual and cognitive deficits, and (ii) reoxygenation of these "silent" neurons provides the basis for neural reactivation and neurological recovery. Controlled trials are now needed to confirm these observations.
