AIM: To evaluate the incidence of supraciliochoroidal fluid(SCF)within 1wk after phacoemulsification combined with goniosynechialysis by anterior segment optical coherence tomography(AS-OCT). <p>METHODS: AS-OCT was used to analyze the incidence of SCF in 40 eyes of 40 patients who received phacoemulsification combined with goniosynechialysis from January 2016 to June 2017. All the patients were diagnosed with primary acute angle-closure glaucoma(PACG)along with cataract. Patients with SCF occurring in 1wk after surgery were included in the SCF group(10 cases with 10 eyes), and patients without SCF were included in the non-occurrence SCF group(30 cases with 30 eyes). Data of intraocular pressure(IOP), central depth of anterior chamber, central macular thickness(CMT), and best corrected visual acuity(BCVA)were collected to further analysis. <p>RESULTS: All the 40 eyes displayed no SCF before surgery. SCF was detected in 10 eyes(25%), which first occurred on 1d(2 eyes), 3d(7 eyes), and 1wk(1 eye)within 1wk postoperatively. SCF was detected in four(7 eyes), two(2 eyes), and one quadrant(1 eye). The whole 10 eyes showed grade Ⅰ(8 eyes)or grade Ⅱ detachment(2 eyes), with no eyes showing grade Ⅲ detachment. Nine eyes had showed no SCF by 4wk, and all SCF disappeared on 8wk. The lowest IOP was significantly lower in eyes with SCF(8.9±0.9mmHg)than in those without(12.5±2.6mmHg)(<i>P</i><0.001). The IOP rose from 10.0±1.2mmHg at the detection of SCF to 14.3±1.5mmHg at the disappearance of SCF(<i>P</i><0.001). BCVA(LogMAR)showed significant positive correlation with central macula thickness(CMT)on postoperatively 8wk(<i>r</i>_s=0.838, <i>P</i><0.001). <p>CONCLUSION: SCF can be detected frequently with AS-OCT at the very early stages after phacoemulsification combined with goniosynechialysis(within 1wk postoperatively), which has fine clinical value.
