case_images: Pre-vitrectomy imaging data showing the cornea and conjunctiva with no abnormal findings. Fundus examination reveals the presence of an epiretinal membrane, and optical coherence tomography angiography examination shows a nonperfusion area related to diabetes mellitus.

case_images: A 73-year-old woman had undergone a 27-gauge pars plana vitrectomy (PPV) for the epiretinal membrane in her right eye (Fig. 1).
case_images: Post-vitrectomy imaging data showing the cornea and conjunctiva with no abnormal findings. On the 14th day post-vitrectomy, bleb formation is observed in the conjunctiva. Subsequently, on the 18th day post-vitrectomy, dellen is observed at the limbus of the cornea, in addition to the bleb formation.

case_images: Fluorescein staining revealed no leakage from the conjunctival wound at the trocar puncture site (Fig. 2). Fluorescein staining revealed no epithelial defects or fluorescein pooling, leading to a diagnosis of dellen (Fig. 2).
case_images: Imaging data demonstrating the disappearance of the bleb and dellen, immediately following scleral and conjunctival suturing.

case_images: In addition, an 8-0 vicryl compression suture was placed on the conjunctiva in the fornix to prevent bleb recurrence (Fig. 3). Nineteen hours after the conjunctival-scleral suturing, the scleral wound was closed, and fluorescein staining revealed no leakage (Fig. 3). The IOP increased to 20 mm Hg, and the bleb and dellen disappeared (Fig. 3).
