Surgical treatment for 42 patients with traumatic annular ciliochoroidal detachment

To analyze the clinical features of traumatic annular ciliochoroidal detachment (CCD) with ultrasound biomicroscopy (UBM) images, to investigate the surgical outcomes of ciliary body suturing and the prognostic factors.

Forty-two patients with traumatic annular CCD who had undergone ciliary body suturing were enrolled for complete ocular examinations, including visual acuity (VA), slitlamp microscopy, tonometer, indirect ophthalscopy and UBM. Comparisons of clinical features were performed among baseline and follow-ups, and the morphologic alterations on UBM images were analyzed between pre- and post-surgery.

The mean intraocular pressure (IOP) was 5.54mmHg, and the median VA was 0.1 in traumatic eyes at baseline. The pre-surgical morphological features on UBM images consisted of supraciliochoroidal effusion (33.33%), multilayer splits (40.48%) and CCD with cyclodialysis cleft (26.19%). After surgery, the median VA was 0.4 at the final follow-up. IOPs were significantly increased, which the mean final IOP was to 10.36mmHg (P<0.01). UBM images displayed complete reattachment in 40.48% of patients, partial reattachment in 50.00% of patients and 360-degree detachment in 9.52% of patients. Analyzing the prognostic factors, the significant factors were duration, VA at baseline, ocular laterality (P<0.01), gender, age and the presence of hypotonous maculopathy (P<0.05).

Ciliary body suturing is the optimized procedure for traumatic annular CCD. UBM is a useful equipment for diagnosis and monitoring post-surgical morphological changes. The periodical detection of IOP and UBM is necessary for the observation of surgical outcomes.
