Objective To explore the clinical effect of cyclocryotherapy for traumatic cyclodialysis.
Methods Four patients (4 eyes) with traumatic cyclodialysis determined by ultrasound biomicroscopy (UBM) and gonioscopy were enrolled. 3 eyes were part of the ciliary body detachment and 1 was annular detachment under UBM. All patients accepted cyclocryotherapy in the case of IOP less than 6mmHg by conservative medical therapy. It is 1.5-2.0mm away from limbus that underwent the operation. The time is 10-15 sounds and the scope of more than a hour out of the cyclodialysis clefts. Eye drops of glucocorticoids were applied after treatment. IOP and the morphologic changes of ciliary were observed by non-contact tonometer(NCT) and UBM.
Results On the second day of postoperatively, IOP increased and visual acuity accordingly improved. The mean IOP was 17.8mmHg at 1 week after surgery. The mean visual acuity improved for more than 4 line. UBM showed all patients had good ciliary body reattachment 1 month after treatment. No ocular or systemic adverse events were found after treatment during the follow-up duration.
Conclusion cyclocryotherapy is a safe and effective method for traumatic cyclodialysis,
which is admitted by a large sample and long-term clinical observation.
