Cyclodialysis cleft repair: A multi-centred, retrospective case series.

IMPORTANCE

There is a paucity of evidence analysing the treatment of cyclodialysis clefts.

BACKGROUND

We describe outcomes following the treatment of this rare condition at six centres internationally.

DESIGN

Retrospective case series.

PARTICIPANTS

Thirty-six patients with a cyclodialysis cleft from 2003 to 2017 were recruited.

METHODS

Clefts were treated with cycloplegic agents, laser therapy and/or surgery.

MAIN OUTCOME MEASURES: Postoperative best recorded visual acuity (BRVA), intraocular pressure (IOP) and the rate of cleft closure.

RESULTS

The mean age was 45 ± 17 years and 29 (80.6%) patients were male. One eye (2.8%) received only medical therapy, 5 (13.9%) received laser, 14 (38.9%) underwent surgery after laser failure and 16 (44.4%) eyes received exclusively surgery. Over 80% of eyes had a BRVA improvement of more than two lines. Closure was attained in 30 eyes (93.8%; n = 32), with postoperative stabilized IOP ≥ 12 mmHg in 29 eyes (80.6%; n = 36) and postoperative BRVA ≤20/50 in 20 eyes (58.8%; n = 34). Improved postoperative BRVA was related to better preoperative BRVA (P = 0.006) and preoperative IOP ≥ 4 mmHg (P = 0.03). There was no significant difference between treatment approach for IOP ≥ 12 mmHg (P = 0.85) or postoperative BRVA ≤20/50 (P = 0.80). Only two eyes at last follow-up required IOP lowering medication.

CONCLUSIONS AND RELEVANCE: There was a high closure rate with most eyes eventually requiring surgery. Clinically significant improvements in BRVA were found in most eyes. Improved postoperative BRVA was significantly related to better preoperative BRVA and IOP.
