Objective To observe the clinical and multimodal imaging characteristics of eyes with acute macular neuroretinopathy (AMN) associated with COVID-19. Methods A retrospective clinical study. From December 18 to 26, 2022, 16 eyes of 8 patients with AMN associated with COVID-19 were included in the study. There were 4 males and 4 females; all cases were bilateral. The age was (31.5±9.6) years old. The time from fever to decreased vision was (3.75±1.04) days. The best corrected visual acuity (BCVA), intraocular pressure, slit lamp microscopy, indirect fundus microscopy, fundus color photography, and optical coherence tomography (OCT) were performed in all patients. Infrared fundus photography (IR), OCT angiography (OCTA) and fluorescein fundus angiography (FFA) were performed in 14, 6 and 4 eyes respectively. The BCVA examination was performed using the international standard visual acuity chart, which was converted into logarithm of the minimum angle of resolution (logMAR) BCVA for statistics. The clinical data, IR, OCT and OCTA imaging features of the patients were retrospectively analyzed. Results The logMAR BCVA of AMN eyes was 4.21±0.74, intraocular pressure was (14.87±1.50) mm Hg (1 mm Hg=0.133 kPa). Fundus color photography showed that multiple gray-white petal-shaped lesions were arranged around the macular fovea in 2 eyes; no obvious abnormality was found in the macular area in 14 eyes. Of the 14 eyes examined by IR, 6 eyes had irregular weak reflective lesions around the macular fovea. OCT showed strong reflex in the outer nuclear layer and outer plexiform layer of all eyes, including 15 eyes with elliptical zone injury. In 6 eyes examined by OCTA, the blood flow density of the superficial and deep capillary plexus (DCP) of retina decreased, and the blood flow density of DCP decreased significantly. The en-face image of DCP showed the wedge-shaped strong reflective lesion area with the tip pointing to the central fovea in 2 eyes. No abnormal fluorescence was observed in FFA. Conclusions The characteristic manifestation of AMN associated with COVID-19 is weak reflex focus in IR; OCT shows strong reflection in outer core layer and outer plexiform layer; OCTA showed that retinal DCP blood flow density decreased.
