A Case of Dellen Formation following 27-Gauge Vitrectomy with Rapid Improvement by Scleral and Conjunctival Sutures
INTRODUCTION: Dellen is a corneal disease characterized by shallow, saucer-like excavations at the corneal margin. Herein, we presented a case of dellen formation that developed following a 27-gauge pars plana vitrectomy (PPV) and was rapidly resolved using scleral and conjunctival sutures. CASE PRE...

Sumario: | INTRODUCTION: Dellen is a corneal disease characterized by shallow, saucer-like excavations at the corneal margin. Herein, we presented a case of dellen formation that developed following a 27-gauge pars plana vitrectomy (PPV) and was rapidly resolved using scleral and conjunctival sutures. CASE PRESENTATION: A 73-year-old woman underwent a 27-gauge PPV for the epiretinal membrane of the right eye. Intraoperatively, owing to coexisting diabetic retinopathy, the peripheral vitreous was shaved, and retinal photocoagulation was performed on the peripheral retina. The intraocular pressure (IOP) was 15 mm Hg on 1 day after the PPV and on postoperative day 4; however, on day 14, the IOP decreased to 10 mm Hg, and conjunctival bleb formation was observed. By day 18, the bleb height remained unchanged, and dellen formation was noted at the corneal periphery. Because of marked corneal thinning, conjunctival and scleral sutures were placed 20 days following the PPV. Intraoperative findings revealed leakage from the scleral wound at the trocar puncture site. The IOP increased to 20 mm Hg at 19 h following the suture, resulting in the disappearance of the bleb and dellen. Since then, the bleb or dellen did not recur. CONCLUSION: We encountered a case of late-onset scleral wound cleavage 2 weeks following microincision vitreous surgery, resulting in bleb and dellen formation, which was immediately managed by the scleral and conjunctiva suturing. |
