Acute macular neuroretinopathy

Cheryl Haskes, Shannon Santapaola, Jordan Zinn
PURPOSE: This is a case presentation of paracentral acute middle maculopathy in a 33-year-old white man with borderline hyperlipidemia. Paracentral acute middle maculopathy was originally thought to be a variant of acute macular neuroretinopathy; however, it is now generally accepted that these two conditions are separate disease entities. The etiology, evolution, and pathophysiology of acute macular neuroretinopathy and paracentral acute middle maculopathy are discussed, as well as current diagnostic techniques...

PURPOSE: Paraneoplastic retinopathy can be the first manifestation of systemic malignancy. A subset of paraneoplastic retinopathy is characterized by negative-type electroretinography (ERG) without fundus abnormality. Here we describe the multimodal imaging and clinico-pathological correlation of a unique case of acute progressive paravascular placoid neuroretinopathy with suspected retinal depolarizing bipolar cell dysfunction preceding the diagnosis of metastatic small cell carcinoma of the prostate...

A 32-year-old woman presented with the acute onset of a small scotoma in the right visual field. She was initially thought to have optic neuritis, but brain magnetic resonance imaging was normal. A review of her symptoms and medications disclosed recent use of oral contraceptives. Near-infrared imaging was the only objective abnormality, consistent with her Amsler grid changes, leading to the diagnosis of acute macular neuroretinopathy.

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...

PURPOSE: To report a case of acute macular neuroretinopathy occurring after intravitreal ranibizumab injection for diabetic macular edema. METHODS: Observational clinical case report. RESULTS: The patient received an intravitreal ranibizumab (0.3 mg) injection for diabetic macular edema. Three days later, he had a decline in vision associated with a central and paracentral scotoma. Optical coherence tomography (OCT) demonstrated bandlike hyperreflectivity of the outer nuclear and plexiform layers corresponding to the patient's scotoma, consistent with the diagnosis of acute macular neuroretinopathy...

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)...

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...
