Double-encircling continuous suture technique for complete cyclodialysis: a consecutive case series

Area of Science:

• Ophthalmology
• Surgical Techniques
• Retinal Diseases

Background:

• Complete cyclodialysis, a condition involving a 360° tear in the ciliary body, often leads to hypotony and vision loss.
• Current surgical options for complete cyclodialysis have varying success rates and potential complications.

Purpose of the Study:

• To evaluate the safety and efficacy of a novel double-encircling continuous suture technique for surgical repair of complete (360°) cyclodialysis.
• To assess anatomical and functional outcomes following this new surgical approach.

Main Methods:

• A retrospective interventional case series of seven patients with complete cyclodialysis.
• Surgical repair involved a double-encircling continuous 10-0 polypropylene suture technique.
• Anterior segment optical coherence tomography (OCT), intraocular pressure (IOP), and best-corrected visual acuity (BCVA) were used for assessment.

Main Results:

• The double-encircling suture technique achieved anatomical reattachment of the ciliary body and resolved hypotony in 85.7% of cases.
• All patients experienced improved BCVA, with outcomes influenced by co-existing ocular conditions.
• Transient IOP elevation occurred postoperatively, necessitating additional glaucoma surgery in two patients.

Conclusions:

• The double-encircling continuous suture technique demonstrates reproducible safety and efficacy for complete cyclodialysis repair.
• This technique offers anatomical success and functional improvement for patients with this condition.
