The effect of topical tropicamide and phenylephrine on macular and peripapillary microvasculature: an optical coherence tomography angiography study.
Article in International ophthalmology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
purposeTo evaluate the effect of topical tropicamide 1% and phenylephrine 2.5% instillation on macular and peripapillary microvasculature measurements with optical coherence tomography angiography (OCTA).
methodsForty eyes of 40 consecutive healthy adults with no known systemic or ocular disease were recruited for this prospective consecutive case study. After complete ophthalmological examination, all patients underwent OCTA measurements (OptoVue Inc, Freemont, CA, USA) to assess foveal avascular zone (FAZ) area, FAZ perimeter, acircularity index of FAZ, foveal density, vessel density of superficial and deep capillary plexus and peripapillary capillary plexus. 6 × 6 mm macular and 4.5 × 4.5 mm peripapillary OCTA images were undertaken before and 30 min after instillation of tropicamide (20 eyes) or phenylephrine (20 eyes) instillation to the right eye, and these were compared to each other and to fellow control eye.
results15 male and 25 female patients with a mean age of 43.3 (18-60) years were recruited for the study. Superficial, deep and peripapillary capillary plexus measurements of tropicamide 1% and phenylephrine 2.5% instilled right eyes and left control eyes were similar before and 30 min after instillation (P > 0.05 for all). FAZ assessment tool variables were also similar before and after instillation (P > 0.05 for all) for both eyes.
conclusionTopical pupillary dilatation with tropicamide 1% and phenylephrine 2.5% did not affect macular and peripapillary OCTA measurements. Follow-up OCTA images in retina and glaucoma patients can be captured with a dilated or undilated pupil which seems not to be affected by tropicamide or phenylephrine.
