SIGNIFICANCE: Cyclodialysis clefts can potentially develop secondary to open globe injury. The swept-source anterior segment optical coherence tomography (SS-AS-OCT) may be a valuable diagnostic tool for the identification and estimation of the circumferential extent of cyclodialysis clefts. It could be considered an alternative when ultrasound biomicroscopy cannot be performed successfully.
PURPOSE: The purpose of this study was to report a case of open-globe injury associated with cyclodialysis cleft and the utility of SS-AS-OCT in its diagnosis.
CASE REPORT: A 12-year-old boy presented to the clinic because of penetrating ocular trauma to his left eye with a projectile stone. He was diagnosed with limbal perforation with uveal tissue prolapse and cataract. He underwent limbal repair with cataract extraction and posterior chamber intraocular lens implantation. However, even at the 6 weeks' post-operative period, he did not gain vision and had persistent hypotony with hypotonic maculopathy. Gonioscopy showed a 2-clock-hour superonasal cyclodialysis cleft. However, on SS-AS-OCT, it was discovered that the cleft extended along 5 clock hours, involving both superonasal and inferonasal quadrants. Recognizing the large extent of the cleft, endocyclopexy by modified sewing-machine technique was planned and performed. An IOP spike and improvement in vision were noted on the next post-operative day. The SS-AS-OCT confirmed cleft closure.
CONCLUSIONS: Although rare, cyclodialysis can occur in cases of open globe injury. The SS-AS-OCT is a useful diagnostic tool to study the circumferential extent of cyclodialysis and may unravel detachments hidden behind intact anterior ciliary body face.
