Article Abstract
Purpose: The purpose of this study is to assess the diagnostic accuracy of paracentral acute middle maculopathy (PAMM) in the setting of anterior ischemic optic neuropathy (AION) to distinguish arteritic (A-AION) from nonarteritic (NA-AION) type.
Design: Retrospective cross-sectional diagnostic evaluation.
Methods: PAMM was evaluated by 3 physicians blinded to diagnosis using macular spectral-domain optical coherence tomography. We studied 45 patients with AION. Of those, 28 had NA-AION and 17 had A-AION. The study was conducted in the Department of Ophthalmology at the Hospital of Marseille-Assistance Publique, France, from January 1, 2018, to March 31, 2022.
Results: PAMM were only found in the A-AION group (N = 4) (P = .0143). As a distinctive sign of A-AION, we found a specificity of 100% (95% IC, 88.06%-100%) and a positive predictive value of 100%. In contrast, sensitivity and negative predictive value were lower, 19.1% (95% IC, 5.5-42.0) and 63.0% (95% CI, 58.1-67.7), respectively.
Conclusions: The PAMM finding is highly specific for A-AION in the setting of AION. According to our results, macular spectral-domain optical coherence tomography looking for PAMM should be performed with any patient presenting with AION.

The occlusion of the short posterior ciliary arteries (SPCAs), a severe yet infrequent ocular vascular pathology, becomes particularly uncommon when it coexists with paracentral acute middle maculopathy (PAMM). We report a rare instance involving a middle-aged male who experienced an occlusion of the posterior ciliary short artery alongside paracentral acute middle maculopathy (PAMM). A 48-year-old male patient presented with a sudden loss of vision in the upper left visual field and a slight decrease in visual acuity.

Background: Structural alterations and functional reorganizations related to motor dysfunction after stroke remain unclear. This study aims to investigate alterations in structural connectivity (SC) and functional connectivity (FC) in non-acute post-stroke patients, and their associations with motor performance.
Methods: Thirty-six non-acute post-stroke patients and thirty-eight well-matched healthy controls (HCs) were included.

Background: Adenosine deaminase-2 (ADA2) deficiency is a rare autosomal recessive autoinflammatory syndrome, typically presenting in young patients with a broad spectrum of phenotypes. These phenotypes usually include primary immune deficiencies, livedo reticularis, and hematological abnormalities. Visual loss associated with ADA2 deficiency is uncommon and, when it does occur, is often linked to major vascular involvement, such as occlusion of the ophthalmic arteries.
