Importance: Acute macular neuroretinopathy (AMN) is a rare, yet increasingly recognized, entity identified predominantly in young healthy females with acute onset of paracentral scotomas. The exact pathophysiology is unknown but an underlying vascular process is suspected. This study used optical coherence tomographic angiography (OCTA) to assess for any evidence of vascular flow abnormality in the retina or choroid in this elusive disease. Observations: Three eyes from 2 young female patients with classic features of AMN are presented...

BACKGROUND: Acute macular neuroretinopathy is a rare disease that with the help of multimodal imaging is being diagnosed more frequently. METHODS: An atypical case is presented and followed by multimodal imaging. RESULTS: A typical acute macular neuroretinopathy lesion was seen on biomicroscopic examination and spectral domain optical coherence tomography examination. However, near-infrared imaging revealed a lack of the characteristic finding along with a relative afferent pupillary defect and a widespread depressed multifocal electroretinogram which has not been reported previously...

A 47-year-old man with recent travel to the Caribbean was admitted with acute febrileillness associated with arthralgia and skin rash followed by sudden onset of bilateral visual field defects. Funduscopy revealed subtle bilateral paracentral dark lesions nasal to the fovea best seen on near infrared imaging as hyporeflective, wedge-shaped, paracentral macular lesions. Spectral-domain optical coherence tomography (SD-OCT) through the lesions revealed hyperreflective bands at the level of the outer plexiform layer and outer nuclear layer (ONL), with concomitant attenuation of the underlying external limiting membrane (ELM), ellipsoid zone (EZ), and interdigitation zone (IZ)...

PURPOSE: To quantitatively evaluate retinal layer thickness changes in acute macular neuroretinopathy (AMN). METHODS: AMN areas were identified using near-infrared reflectance (NIR) images. Intraretinal layer segmentation using Heidelberg software was performed. The inbuilt ETDRS -grid was moved onto the AMN lesion and the mean retinal layer thicknesses of the central grid were recorded and compared with the corresponding area of the fellow eye at initial presentation and during follow-up...

Acute macular neuroretinopathy is a relatively rare condition originally defined by the presence of intraretinal, reddish-brown, wedge-shaped lesions, the apices of which tend to point toward the fovea. Acute onset of paracentral scotomas corresponding to the clinically evident lesions is both common and characteristic. Although the pathogenesis of acute macular neuroretinopathy is complex, recent research suggests a microvascular etiology. Advances in multimodal imaging have enabled better characterization of this retinal disorder and have led to newly proposed diagnostic criteria...

Acute macular neuroretinopathy (AMN) is a rare disorder that presents with abrupt visual change with wedge-shaped or flower-like lesions pointing towards the fovea. Ischemic insults to the retinal capillary plexus may be important for development of this disease. While many case reports have been published on AMN, none have described AMN in association with systemic lupus erythematosus (SLE). Here, we report a case of AMN associated with newly-diagnosed SLE. We speculate that in patients with lupus flares, immune complex-mediated vascular injury and microvascular thrombosis may disrupt the deep retinal capillary network, causing ischemic damages to the outer retina and leading to the development of AMN...

BACKGROUND AND OBJECTIVE: To describe the imaging characteristics and clinical course of acute macular neuroretinopathy (AMN) following non-ocular trauma, and to hypothesize a pathophysiologic mechanism for this syndrome. PATIENTS AND METHODS: The records of five patients who developed symptoms and findings suggestive of AMN following trauma to the face or chest were retrospectively reviewed. Optical coherence tomography (OCT), infrared reflectance, fundus autofluorescence, fluorescein and indocyanine green angiography, and multifocal electroretinography were evaluated...

IMPORTANCE: The incidence of dengue fever (DF) increases every year. Macular complications of patients with DF may be more common than many ophthalmologists realize. During a DF outbreak in South China in 2014, we observed acute macular neuroretinopathy associated with DF. OBSERVATIONS: Among 9 patients (17 eyes) with maculopathy post-DF, 5 patients (55.6%) (9 eyes) manifesting acute macular neuroretinopathy were recruited from August 1, 2014, to September 30, 2014, with a 6-month ophthalmic follow-up...
