ABSTRACT
PURPOSE: To compare retinal changes in young adults with previous SARS-CoV-2 infection with healthy young controls using optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA). METHODS: This prospective single-center study was conducted at the University Hospital of Zurich, Zurich, Switzerland. Participants were imaged from May to November 2021 using the SOLIX device (Visionix International SAS, Pont-de-l'Arche, France). We performed 12 mm × 12 mm, 6.4 mm × 6.4 mm, 6 mm × 6 mm and 3 mm × 3 mm OCT and OCTA scans, as well as fundus photography of each participant's eyes. RESULTS: In total, 466 participants were imaged. Of these, 233 were healthy controls with negative RT-PCR tests for SARS-CoV-2, 168 were young adults who had a SARS-CoV-2 infection at least 180 days previously, 19 were participants who had a SARS-CoV-2 infection < 180 days previously, and 46 were participants with asymptomatic SARS-CoV-2 infection (i.e., serologically positive but with no symptoms). Compared with healthy controls, statistically significant differences were found for OCTA recordings of the optic disc for the whole image (WI) and WI capillary vessel density, with both being higher in the SARS-CoV-2 group. CONCLUSION: Statistically significant results were only observed for selected variables, and in parts, only unilaterally, with relatively large p values (p = 0.02-0.03). Thus, we did not interpret these as clinically significant, leading to the conclusion that young and otherwise healthy individuals (mainly men) seem to recover from mild COVID-19 infections with no ophthalmological residues.
ABSTRACT
INTRODUCTION: To report two cases of Acute Macular Neuroretinopathy (AMN) presented as the first stage of SARS-CoV-2 infection in two European countries during the third wave of pandemic viral infection in the early months of 2021. OBSERVATIONS: A unilateral case of type 1 AMN in a man and a bilateral case of type 2 AMN in an otherwise heathy patients were reported. Sudden onset of paracentral scotoma characterized the cases with no systemic symptoms. Structural optical coherence tomography (OCT) shows multifocal middle and inner retinal hyperreflective infarctions. OCT-Angiography showed the presence of hypoperfusion of the deep capillary plexus (DCP) corresponding to the hyperreflective lesions visible on structural OCT, confirming the diagnosis. CONCLUSIONS AND IMPORTANCE: Type 1 and type 2 AMN may be the first stage of SARS-CoV-2 infection. We suggest testing all patients with AMN for SARS-CoV-2. In our cases, the natural history of AMN associated with SARS-CoV-2 infection was similar to already described cases of AMN.
ABSTRACT
PURPOSE: To assess patient satisfaction regarding the sudden reorganization of care during the COVID-19 pandemic in the outpatient intravitreal injection (IVI) clinic. METHODS: A survey of patients with ongoing IVIs for retinal diseases was carried out between April 23rd and May 12th, 2020. We designed a questionnaire to assess patient satisfaction concerning: personal protective equipment (PPE), social distancing, the perceived quality of care, and the total time spent in the department, using a Likert scale. We also collected the time spent per patients in the outpatient IVI clinic. RESULTS: A hundred and twenty-seven eyes of 108 patients were included. The mean time spent in the IVI outpatient clinic was 31.87 +/- 16.61 min. In our survey, 99.1% of the patients were satisfied (highly satisfied or satisfied) with the new type of care provided, 89.8% with the duration of care, and 93.5% with the PPE. Satisfaction was associated with total time spent in hospital (p = 0.005), with dissatisfied patients spending about 50% more time in the hospital than satisfied patients (43.91 min vs 30.50 min). CONCLUSION: Despite the crisis-related adjustment, our survey revealed high patient satisfaction with PPE, quality of care, and total time spent in outpatient IVI clinic.
