Conclusion: Choroideremia is a disease in which the choriocapillaris maintains a normal structure until the loss of the overlying retinal pigment epithelium. The inner retina also appears not to be affected at the vascular level. Although this study is limited by the small number of patients eligible for inclusion in the study, the observations support the concept of targeting gene therapy to the retinal pigment epithelium and outer retina because there is no evidence of independent degeneration of the choriocapillaris.

Purpose: To report optical coherence tomography angiography (OCTA) values in healthy pediatric eyes and to identify factors that may modify these values. Methods: In this prospective observational cross-sectional study, macular OCTA images were acquired from healthy pediatric patients. Main outcome measures were 1) foveal avascular zone (FAZ) area at the level of the superficial retinal capillary plexus (SCP); 2) SCP and deep retinal capillary plexus (DCP) perfusion density (based on the area of vessels); 3) SCP and DCP vessel density (based on a map with vessels of 1-pixel width); and 4) CC perfusion density. Multipl...

Purpose: To understand the relationship between baseline ischemic index (IsI) values on ultra-widefield fluorescein angiography and classification as ischemic central retinal vein occlusion (CRVO). Methods: Single-center retrospective cohort study of CRVO patients imaged using ultra-widefield fluorescein angiography from which IsI values were calculated. An ischemic CRVO was defined as those eyes with an afferent pupillary defect and counting fingers acuity or worse or neovascularization during the first year of follow-up. Logistic regression was performed to characterize the relation between the IsI and clinical outc...

Conclusion: In this study, statistically significant regression in the NVD size and flow area was observed as early as 24 hours after a single intravitreal bevacizumab injection, with a continued decreasing trend for at least a 1-month period.

The objective of this study was to investigate the effects of using the dTRA on RAO and postprocedural hemorrhage. From April 2018 to July 2018, 228 consecutive patients who underwent coronary angiography or intervention through the dTRA at two hospitals were analyzed. The RAO rate, change in the forearm and distal radial artery diameter and cross-section area after the dTRA (at 1  day and 1 month) on vascular ultrasonography, and incidence of hemorrhagic complications were investigated. Forearm and distal RAO occurred in 1 (0.4%) and 8 (3.1%) patients at 1 month, respectively. No forearm hematomas occurred....

BACKGROUND There are limited data examining the impact of screening for blunt cerebrovascular injury (BCVI) in the geriatric population sustaining falls. We hypothesize that BCVI screening in this cohort would rarely identify injuries that would change management. METHODS A retrospective study (2012–2016) identified patients 65 years or older with Abbreviated Injury Scores for the head and neck region or face region of 1 or greater after falls of 5 ft or less. Patients who met the expanded Denver criteria for BCVI screening were included for analysis. Outcomes were change in management (defined as the initiation...

We report the outer retinal findings on en face optical coherence tomography (OCT) and the alteration of choriocapillaris flow findings on OCT angiography in a patient with ASPPC at the time of presentation, after penicillin treatment completion and during follow-up.Case Rep Ophthalmol 2019;10:165 –171
