Central Retinal Vein Occlusion and Paracentral Acute Middle Maculopathy Diagnosed With En Face Optical Coherence...

A 21-year-old healthy female presented with acute-onset vision loss in the left eye. Multimodal imaging, including fundus photography and fluorescein angiography, was unremarkable. En face optical coherence tomography (OCT) demonstrated paracentral acute middle maculopathy (PAMM) lesions in a perivenular fern-like pattern leading to the diagnosis of central retinal vein occlusion (CRVO). En face OCT can be an important modality to identify the distribution of abnormalities of the middle retina such as PAMM. The distribution of PAMM lesions in the posterior pole will be a critical element in the determination of the etiologic disorder. [Ophthalmic Surg Lasers Imaging Retina. 2016;47:862-864.].
