Bilateral Simultaneous Central Retinal Vein Occlusion Secondary to COVID-19: A Case Report.
Article in Case reports in ophthalmology. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Herein, we report a case of bilateral simultaneous central retinal vein occlusion (CRVO) secondary to coronavirus disease 2019 (COVID-19). A 48-year-old man, with hypertension, type 2 diabetes mellitus, and stage 4 chronic kidney disease, diagnosed with COVID-19 1 month ago presented to the ophthalmology department with blurred vision in both eyes for 2 weeks. Ocular examination revealed a classic clinical presentation of CRVO in both eyes. Optical coherence tomography revealed increased central macular thickness with intraretinal and subretinal fluid in both eyes. Laboratory data revealed elevated D-dimer and C-reactive protein (CRP) levels. The levels of other hypercoagulability markers were normal. The patient received intravitreal anti-vascular endothelial growth factor therapy in both eyes, followed by regular follow-up every month until complete resolution of symptoms and gradual improvement of the retinal vascular appearance. COVID-19 can cause a variety of coagulation abnormalities and thromboembolic complications such as bilateral simultaneous CRVO. Clinicians and patients should be aware of ocular symptoms and presentations that are probably associated with COVID-19.
