ROCKET AF demonstrated the efficacy and safety of rivaroxaban compared with warfarin for the prevention of stroke and systemic embolism (SE) in patients with atrial fibrillation (AF). We examined baseline characteristics and outcomes in patients enrolled in Latin America compared with the rest of the world (ROW).

ROCKET AF enrolled 14,264 patients from 45 countries. Of these, 1,878 (13.2%) were from 7 Latin American countries. The clinical characteristics and outcomes (adjusted by baseline characteristics) of these patients were compared with 12,293 patients from the ROW. Treatment outcomes of rivaroxaban compared with warfarin were also stratified by region.

The annual rate of stroke/SE was similar in those from Latin American and ROW (P= .63), but all-cause and vascular death were significantly higher than in ROW (HR 1.40, 95% CI 1.20-1.64; HR 1.38, 95% CI 1.14-1.68; P< .001). Rates of major or nonmajor clinically relevant bleeding tended to be lower in Latin America (HR 0.89, 95% CI 0.80-1.0; P= .05). Rates of stroke and/or SE were similar with rivaroxaban and warfarin in patients from Latin America and ROW (HR 0.83, 95% CI 0.54-1.29 vs HR 0.89, 95% CI 0.75-1.07; interaction P= .77).

Patients with AF in Latin America had similar rates of stroke and/or SE, higher rates of vascular death, and lower rates of bleeding compared with patients in the ROW. The effect of rivaroxaban compared with warfarin in Latin America was similar to the ROW. Further studies analyzing patient- and country-specific determinants of these regional differences in Latin America are warranted.

To determine the rate of moderate and severe vision loss following herpes zoster ophthalmicus (HZO) and to identify associated factors.

Retrospective cohort study.

All subjects with acute HZO seen at a single center from 2006 to 2016 were included in the study. The primary outcome measure was the proportion of individuals with moderate and/or severe loss of vision following an acute episode of HZO. Secondary outcome measures included causes and factors associated with permanent loss of vision owing to HZO.

A total of 869 patients with acute HZO were identified with a median follow-up time of 6.3 years (interquartile range 3.7-8.9 years). Ocular involvement of HZO was diagnosed at or within the first month of presentation in 737 individuals (84.8%). The most common sites of ocular involvement were conjunctivitis (76.1%), followed by keratitis (51.2%) and uveitis (47.6%). Moderate vision loss (≤20/50) secondary to HZO occurred in 83 eyes (9.6%) while severe vision loss (≤20/200) occurred in 31 eyes (3.6%). Causes of loss of vision included corneal scarring (94.0%), corneal perforation (4.8%), and secondary glaucoma (1.2%). Severe vision loss was associated with older age (hazard ratio [HR] 1.059, P=.001), immunosuppression (HR 3.125, P=.028), poor presenting visual acuity (HR 2.821, P=.002), and uveitis (HR 4.777, P=.004) on multivariate analysis.

Among individuals with HZO, approximately 1 in 10 individuals may develop moderate or severe vision loss, primarily owing to corneal scarring. Older age, immunosuppression, and uveitis are associated with severe permanent loss of vision secondary to HZO.

To elucidate how visual field loss (VFL) impacts self-reported vision-specific quality of life (VSQOL) in African Americans, who experience a disproportionate burden of visual impairment.

Cross-sectional, population-based cohort.

Eligible participants (n=7,957) were recruited who self-identified as African American, were aged 40 years or older, and resided in Inglewood, California, USA. A total of 6,347 participants (80.0%) completed clinical eye examinations. Total mean deviation (MD) of VFL was measured bilaterally as decibels (dB) using the Humphrey SITA Standard 24-2 test. VSQOL was measured using the National Eye Institute Visual Function Questionnaire (NEI-VFQ 25) and scored using item response theory (IRT).

Participants with reliable data (n=5,121) had a mean age of 60.7 years (standard deviation 11.0); those with worse VFL were older; had more comorbidities, lower income, less education, and worse visual acuity; and were more likely to be unemployed and depressed. Using IRT analysis, a change in VF of 6.2 (95% confidence interval [CI] 5.3, 7.7) dB and 9.2 (95% CI 7.5, 11.9) dB was necessary to observe a meaningful (5-point) difference in vision-related task and emotional well-being scores, respectively. VFL had the greatest impact on self-reported driving ability (6.0 dB [95% CI 5.2, 7.1]), followed by satisfaction with general vision, near vision, vision-related mental health, and peripheral vision.

The strongest impact of VFL reported by African Americans was on their ability to complete visual tasks, especially for driving. An effect of VFL on emotional well-being also was observed, but the magnitude of association was about 50% lower for well-being compared to that of task.

To quantify in vitro straylight induced by intraocular lens (IOL) localized opacification using an anterior segment optical coherence tomography (OCT) device.

Laboratory investigation.

We obtained high-resolution OCT cross-section images of 44 explanted IOLs using a new in vitro application for an anterior segment OCT device, the Anterion (Heidelberg Engineering, Heidelberg, Germany). In 24 cases, the reason for IOL explantation was a centrally localized opacification, the sequela of a secondary ocular surgery. As a control, we used 20 IOLs removed after an IOL (sub-)luxation. Using image analysis, we found a threshold area value representing a metric for the amount of opacification in a region of interest in the IOL's central optic. ACY1215 We used a modified C-Quant straylight meter (Oculus, Wetzlar, Germany) to quantify light scattering. We derived a linear regression from calculating the correlation between the amount of opacification and straylight.

We visualized different amounts of IOL opacification using the OCT device.
