Artificial intelligence-assisted quantitative evaluation of upper eyelid blepharoplasty outcomes in dermatochalasis: methodological validation and clinical correlation.
Article in BMC ophthalmology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
BACKGROUND AND
aimsThis prospective study aimed to assess the functional and aesthetic outcomes of upper eyelid blepharoplasty in patients with dermatochalasis using a validated artificial intelligence (AI)–assisted morphometric analysis system and to determine its accuracy, reproducibility, and clinical applicability.
methodsTwenty‑five patients (50 eyelids) with age‑related dermatochalasis underwent standardized upper eyelid blepharoplasty between April and November 2024. High‑resolution periocular photographs were obtained preoperatively and at 2 weeks postoperatively. Morphometric parameters—including MRD‑1, PFH, TPS, and BFS—were quantified automatically using a hybrid MediaPipe–OpenCV pipeline. Bilateral symmetry was quantified using an Asymmetry Index. Changes between pre- and postoperative asymmetry indices were analyzed using the Wilcoxon signed-rank test. Synthetic images were used solely for calibration, while all outcome measurements were derived from real patient photos. Accuracy was validated through manual measurements by two ophthalmologists, yielding an intraclass correlation coefficient (ICC) of 0.93 (p < 0.001).
resultsAll patients completed follow‑up. The AI system demonstrated 97.5% accuracy and significant postoperative improvements across all parameters (p < 0.001) such as 86.7% precision, and a 92.9% F1-score in landmark detection, with a mean IoU of 0.82 and mAP > 0.80. Measurement variability decreased 68% versus manual methods. Area under the ROC curve (AUC) was 0.85 (95% CI 0.78–0.91), confirming strong discriminative power.
conclusionAI‑assisted morphometric analysis allows objective, reproducible, and quantitative evaluation of blepharoplasty outcomes, minimizing observer bias and establishing standardized benchmarks for future surgical audits.
