Changes in pupillographic and ocular surface parameters following upper eyelid blepharoplasty.
Observational study in International 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
purposeTo evaluate changes in pupillary responses, meibomian gland morphology, and tear film stability following upper eyelid blepharoplasty and to characterize the postoperative patterns of these parameters at the third postoperative month.
methodsThis retrospective longitudinal observational study included 90 eyes of 45 patients (mean age, 57.6 ± 9.18 years) who underwent orbicularis-preserving upper eyelid blepharoplasty. Preoperative and third-month postoperative assessments comprised pupillography (scotopic, mesopic, and photopic pupil diameters; 10-s redilation velocity), non-contact infrared meibography, and noninvasive tear film breakup time (NI-FBUT and NI-AvgBUT). Preoperative and postoperative outcomes were analyzed using linear mixed-effects models to account for within-patient inter-eye correlation.
resultsPhotopic and mesopic pupil diameters showed significant postoperative reductions (p = 0.011 and p = 0.002, respectively), accompanied by a decrease in redilation velocity (p = 0.018), while scotopic pupil diameter remained unchanged. Meibomian gland loss area showed a mild, nonsignificant increase, while NI-FBUT and NI-AvgBUT showed nonsignificant postoperative increases.
conclusionsUpper eyelid blepharoplasty was associated with small reductions in mesopic and photopic pupil diameters and redilation velocity at the third postoperative month. No statistically significant changes were detected in the evaluated tear-film or meibography parameters. The physiological mechanisms underlying the observed pupillometric changes cannot be determined from the present study.
