ABSTRACT
Paracentral acute middle maculopathy (PAMM) is an optical coherence tomography (OCT) finding seen in patients with retinal capillary ischemia. In this case report, we present a case of PAMM after a transient central retinal artery occlusion and the multifocal electroretinogram (mfERG) and other multimodal imaging findings. Clinical examination, OCT angiography, OCT en face, fluorescein angiography, and visual fields were performed at the baseline and follow-up examinations. As a result, we identified in this PAMM case evidence of hypoperfusion in both the choriocapillaris as well as the deep capillary plexus. To the best of our knowledge, the involvement of choriocapillaris has not been reported previously in the literature. Moreover, we concluded that mfERG constitutes a useful investigation in PAMM and this is the first mfERG findings to be presented for a PAMM case specifically.

PURPOSE: To report a case of acute bilateral central serous retinopathy associated with deferoxamine therapy in the context of paroxysmal nocturnal hemoglobinuria. METHODS: Spectral-domain optical coherence tomography and fundus autofluorescence were used to investigate posterior segment changes. RESULTS: A 76-year-old man with paroxysmal nocturnal hemoglobinuria and hereditary spherocytosis was started on deferoxamine for iron overload secondary to previous blood transfusions. Four days after initiation of treatment, he developed bilateral reduced vision and metamorphopsia. He was noted to have bilateral central serous retinopathy. Symptoms and serous retinal detachment resolved rapidly following discontinuation of treatment. CONCLUSIONS: This case represents the first report of acute bilateral central serous retinopathy associated with deferoxamine therapy. Cessation of deferoxamine resulted in rapid visual recovery.
