Quantitative assessment of subfoveal choroidal thickness, retinal thickness, and choroidal vascularity index after upper eyelid blepharoplasty.

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 quantitative changes in subfoveal choroidal thickness (CT), retinal thickness, and choroidal vascularity index (CVI) following upper eyelid blepharoplasty in patients with dermatochalasis, using spectral-domain optical coherence tomography (SD-OCT).
methodsThis retrospective study included 78 eyes of 78 patients (mean age: 57.9 ± 8.7 years) who underwent upper eyelid blepharoplasty between May 2024 and May 2025. Only right eyes with high-quality SD-OCT images obtained both preoperatively and at 3 months postoperatively were included. Retinal thickness was assessed in 9 ETDRS subfields. Subfoveal CT and CVI were measured using horizontal B-scan images. CVI was calculated based on the binarization method described by Agrawal et al., using ImageJ software. Pre- and postoperative values were compared using paired t-tests or Wilcoxon signed-rank tests depending on normality.
resultsSubfoveal CT significantly increased after surgery (287.22 ± 39.67 µm to 294.23 ± 39.74 µm; p = 0.030). A marked increase in CVI was also observed (61.48 ± 9.13% to 63.63 ± 9.13%; p < 0.001). No significant differences were detected in most retinal segments, except for the inferior inner (p = 0.016) and inferior outer (p = 0.002) regions, which showed statistically significant thickening postoperatively.
conclusionsUpper eyelid blepharoplasty is associated with measurable structural changes in the posterior segment, including increased subfoveal CT and CVI, as well as regional thickening of the inferior retina. These findings suggest that blepharoplasty may influence choroidal hemodynamics and retinal adaptation beyond its functional and cosmetic benefits.
