The Effect of Ocular Hypotensive Medications on Posterior Segment Blood Flow in Healthy Subjects: A Prospective, Randomized, and Interventional Study.

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
Purpose: To evaluate the immediate impact of topical ocular hypotensive medications on peripapillary and macular blood flow in healthy adults from Northeast Iran. Methods: A prospective, randomized, and interventional study was conducted on 80 healthy volunteers, with each volunteer having one eye treated with either brimonidine, dorzolamide, latanoprost, or timolol, all of which are ocular hypotensive medications. The study included a placebo treatment for one eye of each participant to serve as a control. At the peak effect of the drugs, all participants underwent an optical coherence tomography angiography scan of their eyes. A total of 160 eyes were included in the study. Results: According to the findings, the use of ocular hypotensive drugs did not demonstrate any significant influence on the radial peripapillary capillary network. However, the results indicated that a single dose of dorzolamide could result in a significant increase in macular blood flow ( Conclusions: According to our findings, dorzolamide was the most effective in enhancing young adults' full macular thickness and macular blood flow. Conversely, timolol treatment was found to decrease the macular blood flow, which in turn may cause visual field defects due to optic nerve head and macular ischemia in patients with low-tension glaucoma.
