Abstract
Purpose: :
To illustrate the value of spectral-domain optical coherence tomography ( SD -OCT) concerning the diagnosis and pathogenesis of acute macular neuroretinopathy (AMNR).
Methods: :
We report three cases of young women suffering from acute macular neuroretinopathy. We performed detailed clinical examination with additional imaging using infrared light (IR), Fluorescein angiography (FA), Indocyanine green angiography (ICG) and SD- OCT .
Results: :
In the three patients, fundoscopy revealed very discrete macular lesions. The fundus lesions were best seen with IR light as reddish petaloid lesions.Fluorescein angiography and indocyanine green angiography were normal.In the three cases, OCT showed focal disruption of the inner /outer photoreceptor segment (IS/OS) junction.In the two cases seen in the first day of the onest of the symptoms, OCT revealed an hyper-reflectivity of the photoreceptor layer, corresponding probably to an inflammatory reaction.
Conclusions: :
Our findings show involvement of the outer retina, and confirm OCT as an important tool for diagnosis in AMNR, as other diagnostic tests often remain normal
