Résumé

Purpose@#To analyze the repeatability of vessel density (VD) measurements and manual foveal avascular zone (FAZ) measurements using optical coherence tomography angiography (OCTA) in patients with retinal vein occlusion (RVO) without macular edema. @*Methods@#The study population consisted of patients with RVO and central macular thickness @*Results@#A total of 48 eyes were included in the study. The ICCs of the VDs in superficial capillary plexus (SCP) and the deep capillary plexus (DCP) were 0.748 and 0.665, respectively, and the CVs of the VDs in SCP and DCP were 9.1% and 12.6%, respectively. The ICCs associated with the FAZ of the superficial layer (SFAZ) and that of the deep layer (DFAZ) were 0.965 and 0.956, respectively, and the CV of the SFAZ and DFAZ were 8.8% and 9.7%, respectively. From Pearson correlation analyses, OCTA quality was significantly correlated with the CV of the VDs of SCP and DCP. However, there were no variables that were significantly correlated with the CV of SFAZ and DFAZ, including OCTA quality. @*Conclusions@#VD measurements in the SCP layer using OCTA exhibited good repeatability, and VD measurements in the DCP layer exhibited relatively low repeatability compared to that of SCP layer measurements in patients with RVO without macular edema after treatment with bevacizumab. Manual measurement of the FAZ area in both SCP and DCP layers resulted in good repeatability. In addition, the repeatability of VD measurements in SCP and DCP layers was correlated with OCTA image quality.

Résumé

PURPOSE@#This study aimed to investigate the incidence of increased intraocular pressure (IOP) and the clinical course of traumatic hyphema.@*METHODS@#We retrospectively reviewed the medical records of traumatic hyphema patients from March 2016 to January 2019. Based on whether the IOP exceeded 21 mmHg, the patients were divided into two groups: increased IOP (IIOP) hyphema grade, and intraocular damage. We compared the two groups based on sex, age, cause of trauma, IOP, visual acuity, follow-up period, and hyphema grade. The IIOP group was also divided into two groups: treatment continuation and treatment termination. We compared the two groups on the same aforementioned basis.@*RESULTS@#Of the 181 eyes, 53 (29.3%) were in the IIOP group. The initial IOP (p < 0.001), hyphema grade (p < 0.001), rebleeding incidence (p = 0.011), and intraocular damage (p = 0.027) were statistically significant between the two groups. The treatment continuation group for IIOP had 11 (20.8%) eyes, and the age (p = 0.029) and intraocular damage (p = 0.010) were statistically different from the treatment termination group.@*CONCLUSIONS@#The incidence of increased IOP was 29.3%. Continuous treatment was needed in 20.8% of the increased IOP cases, and the age and intraocular damage were related.
