A Case of Branch Retinal Arteriole Occlusion and Paracentral Acute Middle Maculopathy after COVID-19 Infection.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The aim of this study was to report a case of segmental deep capillary plexus ischemic injury after COVID-19 infection in a vaccinated otherwise healthy male. Case Presentation: A healthy 38-year-old male presented with a complaint of not being able to see above his fixation point in the left eye. He had developed a positive scotoma 2 weeks after a COVID-19 infection. Examination showed a branch retinal arteriole occlusion in the inferotemporal quadrant with an area of subtle arcuate retinal whitening inferior to the fovea. Systemic workup was unremarkable. His vision remained 20/20, with a persistent scotoma over 2 months. Severe thinning of the inner nuclear layer and marked attenuation of the outer plexiform layer in an arcuate segment inferior to the fovea were detected with optical coherence tomography (OCT). OCTA revealed a flow void in the deep capillary plexus inferior to the fovea and cessation of the blood flow distal to the occluded retinal arteriole. Conclusion: This case highlights the deep capillary plexus's unique vulnerability to COVID-19-related occlusion, likely due to its high autoregulatory demand and dense vascular architecture. It emphasizes the need for further investigation into retinal microvascular complications of the disease.
