Abstract Purpose:Herein, we report a case of hypotony maculopathy resulting from a 360° traumatic cyclodialysis cleft, successfully treated with vitrectomy, gas tamponade, and cyclocryopexy.

Case:A 48-year-old woman sustained blunt trauma to the left eye from a badminton shuttlecock, initially presenting with an intraocular pressure(IOP) of 29 mmHg and hyphema. Although the IOP was initially lowered with glaucoma medication, she suffered a similar trauma to the same eye 4 days after the initial injury. Her best-corrected visual acuity(BCVA) decreased to 0.15, and the IOP was low(5 mmHg). Anterior segment optical coherence tomography(AS-OCT) confirmed a 360° cyclodialysis cleft, complicated by macular folds owing to hypotony maculopathy. Conservative treatment, including 12 months of anti-inflammatory treatment with a sub-Tenon's injection of triamcinolone acetonide and atropine eye drops, failed to resolve the clefts;the IOP remained between 4 and 7 mmHg, hypotony maculopathy persisted, and BCVA was 0.2. Pars plana vitrectomy, SF6 gas tamponade, and circumferential transscleral cyclocryopexy were performed to repair the cyclodialysis cleft and normalize the IOP.

Results:Immediately postoperatively, the IOP elevated to 78 mmHg, thereby necessitating gas drainage. One week postoperatively, AS-OCT confirmed the closure of the cyclodialysis cleft, and the BCVA improved to 1.0. The IOP stabilized at 7-10 mmHg, and the hypotony maculopathy resolved completely.

Conclusion:Reattachment of the ciliary body over a wide area is required for traumatic cyclodialysis clefts extending 360°, particularly if direct suturing is excessively invasive. For such cases, the combination of vitrectomy, SF6 gas tamponade, and cyclocryopexy is an effective surgical alternative.
