Orbital arteriovenous fistula presenting with choroidal pulsations on optical coherence tomography.

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
purposeTo describe a case of orbital arteriovenous fistula diagnosed based on choroidal pulsations on optical coherence tomography (OCT). OBSERVATIONS: A 69-year-old female originally referred for evaluation of macular degeneration. During acquisition of OCT images, choroidal pulsations of the right eye were noted on the B-scan on the instrument display. The pulsations were not noted on gross or funduscopic examination. Fluorescein angiography was unremarkable. Indocyanine green angiography revealed engorged choroidal vasculature in the right eye. OCT angiography revealed relative tortuosity and dilation of the superficial and deep vascular complexes respectively. B-scan ultrasonography revealed orbital pulsations on the right. MRI imaging of the brain and orbits was unremarkable. Findings were attributed to a low-flow orbital arteriovenous fistula. The patient subsequently developed mild stasis retinopathy for which anti-VEGF therapy was initiated. CONCLUSIONS AND IMPORTANCE: Arteriovenous fistulas of the brain and orbit classically present with gross pulsatile proptosis among other clinical features. Low flow orbital fistulas may present with subtle choroidal pulsations only detectable on OCT.
