[Traumatic cyclodialysis treated with cryopexy]

Area of Science:

• Ophthalmology
• Ocular Trauma
• Diagnostic Imaging

Background:

• Cyclodialysis involves ciliary muscle separation from scleral insertion, leading to ocular hypotony.
• Traumatisms are the primary cause of cyclodialysis.
• Traditional diagnosis via gonioscopy is increasingly supplemented by advanced imaging.

Observation:

• A 57-year-old male experienced severe left eye trauma from a radial saw, resulting in corneal perforation and vitreous hemorrhage.
• Despite persistent ocular hypotony, gonioscopy revealed normal findings.
• Ultrasound biomicroscopy (UBM) identified a small cyclodialysis measuring less than ten degrees.

Findings:

• UBM proved superior to gonioscopy in diagnosing subtle cyclodialysis post-trauma.
• Early diagnosis of cyclodialysis is crucial for managing ocular hypotony.

Implications:

• This case highlights UBM's value in diagnosing traumatic cyclodialysis when gonioscopy is inconclusive.
• Prompt surgical intervention for cyclodialysis can restore normal intraocular pressure and visual function.
