    The study analyzed postoperative changes in retinal vessel diameter and optic disc morphology in pediatric glaucoma patients.

  • 2

    Glaucomatous eyes showed significantly narrower peripapillary vessel diameters preoperatively compared to age-matched controls.

  • 3

    Post-surgery, despite reduced intraocular pressure, major retinal vessels remained abnormally narrow in glaucomatous eyes.

  • 4

    A subset of patients exhibited cup reversal correlated with inferior rim widening, indicating limited optic cup remodeling.

  • 5

    Preoperative disc hemorrhage and higher β-zone PPA Regularity Index were identified as independent predictors of cup reversal.
