Comparative analysis of optical coherence tomography angiography findings before and after flow-diverting stent treatment covering the ophthalmic artery origin in the management of paraclinoid aneurysms.

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
purposeFlow-diverter stents (FDSs) are being increasingly used for endovascular treatment of paraclinoid aneurysms. However, their impact on ophthalmic artery (OA) flow and retinal microvasculature remains unclear. Using optical coherence tomography angiography (OCTA), we evaluated the microvascular changes after FDS placement on the OA.
methodsThis retrospective study included 38 patients with paraclinoid aneurysms who had an FDS placed on the OA origin. OCTA imaging was performed preoperatively, on postoperative day 1, and at the 6th month. The superficial and deep capillary plexus (SCP, DCP) densities in the treated and untreated fellow eyes were determined and compared with a control group of 31 healthy individuals who underwent single-session OCTA. OA status and stent-related changes were assessed at the 6th month follow-up with digital subtraction angiography (DSA).
resultsA significant reduction in SCP and DCP densities was observed in the stent-treated eyes over time, particularly in the central, superior, temporal, and inferior regions (p < 0.05), while untreated fellow eyes and controls showed no significant changes.
conclusionFDS placement covering the OA orifice leads to measurable retinal microvascular changes that are detectable by OCTA, demonstrating the value of the latter as a useful non-invasive tool for this purpose.
