Apr 1, 2019 · In AMN, however, the retinal vessels and optic nerve are unaffected, and AMN lesions typically resolve over several weeks to months with corresponding visual recovery [2]. Additionally, these macular lesions are often associated with recent viral-like illness, oral contraceptive use, or exposure to sympathomimetics [3].

Feb 8, 2008 · Acute macular neuroretinopathy (AMN) is a rare disease of unknown etiology that most commonly affects young to middle-aged females. The patient typically presents with the acute-onset of one or multiple paracentral scotomas that affect one or both eyes. This is typically the only symptom and visual acuity is unaffected.

Jun 10, 2020 · On OCT for example, hyperreflective abnormalities in AMN are deeper in the retina, located at the junction of the outer plexiform layer (OPL) and outer nerve layer (ONL) [2]. In contrast to PAMM lesions, which typically correspond to DCP flow loss, the primary insult in AMN is thought to involve the inner choroid [20,21].

Feb 28, 2022 · Transient hyperreflectivity of the outer retina may also be seen at the inner segment/outer segment junction on OCT [23-25]. Certain OCT findings, including foveal thickness at initial presentation and grade of outer retinal atrophy, have been identified as possible predictors of final visual outcome [20].

Apr 8, 2005 · Discussion. MEWDS (Multiple Evanescent White Dot Syndrome) is a rare, unilateral, self-limiting inflammatory disease that afflicts young women more than men in a 4:1 ratio.

Retinopathy associated with leukemia typically occurs in acute disease. Patients may develop dilation, tortuosity, and beading of the retinal veins; vascular sheathing; cotton-wool spots; flame-shaped hemorrhages; Roth spots; sub-hyaloid and sub-internal limiting membrane hemorrhages.

Jan 22, 2014 · A perfused retina is a happy retina. The outer one-third of the retina receives its blood supply from the choriocapillaris, a vascular network that lies between the retina and sclera. The inner two-thirds of the retina is supplied by branches of the central retinal artery, which comes from the ophthalmic artery (the first branch off of the ...

AMN is a rare posterior uveitis condition characterized by paracentral scotomas defined by red-brown petalloid or wedge-shaped lesions within the deeper vascular layers of the retina. This condition threatens acute vision loss most often in young adults with a flu-like prodrome but is often self-limited or improves after treatment of underlying ...
