Abstract：
BACKGROUND:To evaluate the changes of choroidal vascular structures in patients after phacoemulsification surgery. METHODS:A self-control study was conducted on 36 eyes of 36 patients who had uneventful phacoemulsification. Choroidal images were acquired preoperatively, 7 days (D7), 1 month (M1), and 3 months (M3) after surgery from enhanced depth imaging (EDI) optical coherence tomography (OCT) scans. Choroidal vascularity index (CVI) was used to assess vascular status of the choroid using image binarization by the Niblack method. The postoperative values of mean CVI were compared with baseline by paired t-test. Univariate and multiple linear regression analyses were performed to determine the associations between CVI and other factors. RESULTS:The mean age of the recruited patients was 63.1 ± 6.9 years. The mean CVI at baseline was 60.1 ± 5.5%. After surgery, the CVI significantly increased to 61.7 ± 5.3% at D7, 63.6 ± 4.4% at M1 and 64.8 ± 4.0% at M3 (p = 0.035, 0.0006, < 0.0001, respectively). Univariate and multiple regression analysis revealed a positive association between CVI and subfoveal choroidal thickness (SFCT) at pre-operation and no significant association with age, axial length (AL), intraocular pressure (IOP) and gender at all timepoints. CONCLUSIONS:Phacoemulsification induced increased CVI in patients diagnosed with cataract. Evaluation of the long-term change of CVI following surgery may provide valuable information for studying the relationship between phacoemulsification and disorders of the choroid.
