METHODS:A retrospective study was performed for 6 eyes(6 cases)diagnosed as CCH. Before treatment, OCT examination showed macular cystoid edema and retinal neurepithelium layer detachment in all patients. All patients underwent photodynamic therapy, then intravitreal injection of ranibizumab 0.5mg(0.05mL)were administered at 48h after PDT. The best corrected visual acuity(BCVA), examination of the ocular fundus, fundus photography, fluorescence fundus angiography(FFA), indocyanine green angiography(ICGA), eye B ultrasonic and optical coherence tomography(OCT)were performed respectively at 1, 3 and 6mo after treatment.

RESULTS:The patients were followed up for 4 to 10mo, the final vision of follow-up increased than before, it was raised 7 lines. The images of ICGA revealed hypofluorescence or no leakage in focal area. Eye B ultrasonic showed that hemangioma shrunk or faded. The images of ICGA revealed macular region retinal reattached well and edema disappeared completely. Mean flow-up was 6mo postoperative. There had no evidence of recurrence.

CONCLUSION:For CCH patients, hemangioma got smaller obviously by PDT. Intravitreal ranibizumab injection promote effusion absorption under the retina. Combining use of the two therapies could improve visual acuity in a short-term.
