Acute macular neuroretinopathy

Michael S Vaphiades, Brendan Grondines
A 19-year-old Caucasian woman developed an upper respiratory infection, took a cold formulation containing 5 mg of phenylephrine, and developed a very rare and unusual form of acute macular neuroretinopathy (AMN) that could not be detected on fundoscopic examination, visual fields, nor electrophysiological testing. Spectral-domain optical coherence tomography (SD-OCT) revealed a lesion limited to the fovea. This case illustrates the value of SD-OCT, in light of otherwise normal testing, in a variant of AMN the authors call "occult AMN"...

PURPOSE: To report the clinical findings of the youngest confirmed case of acute macular neuroretinopathy to the best of our knowledge. METHODS: A 9-year-old patient describing a paracentral scotoma with a normal clinical examination and normal fluorescein angiography. RESULTS: Initial fundus examination was unremarkable. Fluorescein angiography findings showed no abnormalities but scotoma was confirmed using Amsler grid. Optical coherence tomography showed a parafoveal hyperreflective band in the outer layers...

A 39-year-old female with dengue fever presented with decreased vision in both eyes. Visual acuity was 20/200 and 20/80 in the right eye (OD) and left eye (OS), respectively. Fundus showed granular, grayish-white lesions in the parafoveal region in OD. Multimodal imaging including optical coherence tomography angiography (OCTA), optical coherence tomography (OCT), and fluorescein angiography (FA) was performed. FA showed late hyperfluorescence with few microaneurysms in OS. OCT showed hyperreflectivity in various layers, suggestive of acute macular neuroretinopathy (AMN)...

PURPOSE: To classify and characterize AMN lesions with SD-OCT during a follow-up as long as 5 years. METHODS: Retrospective study of 14 patients (18 eyes) with special focus on SD-OCT. We measured thickness of inner nuclear layer (INL), outer retinal layer (ONL), and hyperreflective band at baseline and during follow-up. AMN lesions were classified as type 1 and type 2. RESULTS: Of 14 patients (six males, eight females, mean age 29.7 years), three patients (four eyes) had type 1 and nine (12 eyes) had type 2...

PURPOSE: To describe the case of a born HIV seropositive woman who developed outer retinal alterations secondary to vascular abnormalities in the perimacular region and in the periphery of both eyes. METHODS: Case report. RESULTS: A 21-year-old woman born HIV seropositive was referred for a routinary visit. Her best-corrected visual acuity was 20/20 in both eyes, and during the visit, only mild superotemporal metamorphopsia in the left eye was reported...

Importance: Acute macular neuroretinopathy (AMN) is a rare, idiopathic condition resembling other acute maculopathies such as paracentral acute middle maculopathy. The pathophysiology of AMN is not well understood, and the role of the choroid in the pathogenesis of AMN remains controversial. Objective: To describe initial and serial multimodal imaging findings in AMN, with attention to choroidal vascular changes. Design, Setting, and Participants: Retrospective case series at a single institution, tertiary referral center...

Terson syndrome is defined as the incidence of intraocular hemorrhage in patients following a subarachnoid or intracranial bleed. A 38-year-old female with both intraretinal and subretinal hemorrhages secondary to Terson syndrome underwent repair of a ruptured cerebral aneurysm. One month following resolution of the macular hemorrhages, a paracentral scotoma persisted. Multimodal imaging (morphological and functional) confirmed the presence of acute macular neuroretinopathy Type 2 associated with deep retinal capillary ischemia...

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...

BACKGROUND The aim of this study was to assess the clinical course and distinctive features of different white dot syndromes (WDS) in patients attending the Ophthalmology Department, Medical University of Warsaw in the years 1995-2015. MATERIAL AND METHODS Sixty-two (62) patients (43 females and 19 males), aged 18 to 77 years, referred with a WDS were included in this prospective study, with observation period ranging from 5 months to 16 years. All patients underwent a complete ophthalmological examination and multimodal imaging studies...

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.

PURPOSE: To present en face optical coherence tomography (OCT) images generated by graph-search theory algorithm-based custom software and examine correlation with other imaging modalities. METHODS: En face OCT images derived from high density OCT volumetric scans of 3 healthy subjects and 4 patients using a custom algorithm (graph-search theory) and commercial software (Heidelberg Eye Explorer software (Heidelberg Engineering)) were compared and correlated with near infrared reflectance, fundus autofluorescence, adaptive optics flood-illumination ophthalmoscopy (AO-FIO) and microperimetry...

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 an unusual case of ciliochoroidal effusion and presumed acute macular neuroretinopathy associated with cervical traction therapy for the treatment of cervical spinal stenosis. METHODS: Case report. RESULTS: A 75-year-old man reported sudden onset of a wedge-shaped paracentral scotoma in the right eye. Fundus examination showed a ciliochoroidal effusion in the right eye. Optical coherence tomography revealed intraretinal fluid in both eyes without leakage on fluorescein angiography...

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...
