To identify predictive response optical coherence tomography (OCT) findings in uveitic macular edema (UME) treated with intravitreal dexamethasone implant (DEX).

Retrospective study of 66 eyes (53 patients) treated with DEX for UME. SD-OCT macular scans were collected prior to DEX treatment and 6weeks and 3months after the DEX implant. OCT images were evaluated for qualitative and quantitative characteristics (central retinal thickness, CRT and macular volume, MV). A multivariate analysis of covariance (ANCOVA) was carried out to study the predictive influence of OCT and clinical covariates on outcomes. The main outcome was a composite endpoint based on the simultaneous gain of 5 or more letters associated with a 20% or more reduction in CRT.

A significant improvement in BCVA at 6weeks (mean change from baseline -0.2, SD 0.3) and 3months (mean -0.2, SD 0.4) was observed after the DEX implant. A significant decrease in CRT (change from baseline -187.7μm at 3months) and MV (change from baseline -1.7 mm
at 3months) were also observed. An association of ≥ 5-letter improvement in BCVA and a ≥ 20% CRT reduction was observed in 44.6% of cases at 6weeks and 31.4% at 3months. ANCOVA multivariate analyses found CRT at 3months independent from baseline clinical variables but from CRT.

DEX implant is an effective treatment for UME independently of basal characteristics, producing both a gain of visual acuity and improvement of macular anatomy by OCT measures at 3months.

To evaluate the time trend of axial length (AL) and associated factors in 4- and 5-year-old children in Shanghai from 2013 to 2019.

This was a 7-year observational study of 985 four-year-old and 1059 five-year-old children in Shanghai. AL, horizontal and vertical corneal curvature, spherical equivalent (SE), and body height and weight were measured. Furthermore, a questionnaire was collected, including time outdoors and bad eyesight habits.

In 4-year-old children, no significant difference was found in AL (P = 0.526), but significant differences were observed in SE (P = 0.001), horizontal corneal curvature (P = 0.006), vertical corneal curvature (P = 0.004), height (P < 0.001), and weight (P = 0.022) from 2013 to 2019. In 5-year-old children, no significant differences were found in AL (P = 0.304), SE (P = 0.200), or weight (P = 0.292), but significant differences were observed in horizontal corneal curvature (P = 0.040), vertical corneal curvature (P = 0.015), and height (P < 0.001) from 2013 to 2019. Multivariate analyses revealed that AL was mainly significantly associated with boys and time outdoors in the 4- and 5-year-old children.

The AL of 4- and 5-year-old children remained relatively stable in Shanghai from 2013 to 2019. Longitudinal studies are needed to confirm the relationship between AL elongation and environmental risk factors.

Cather ablation is known to influence the autonomic nervous system. This study sought to investigate the association of sinus heart rate pre-/post-ablation and recurrences in patients with atrial fibrillation undergoing pulmonary vein isolation (PVI).

Between January 2012 and December 2017, data of 482 patients undergoing their first PVI were included. Sinus heart rate was recorded before (PRE), directly post-ablation (POST) and 3months post-ablation (3M). All patients were screened for atrial tachyarrhythmia recurrences during the one-year follow-up.

In the total study cohort, the mean resting sinus heart rate at PRE [mean 57.9bpm (95% CI 57.1-58.7bpm)] increased by over 10bpm to POST [mean 69.4bpm (95% CI 68.5-70.3bpm); p < 0.001] followed by a slight decrease at 3M [mean 67.3bpm (95% CI 66.4-68.2bpm)] but still remaining higher compared to PRE (p < 0.001). This pattern was observed in patients with and without recurrences at POST and 3M (both p < 0.001 compared to PRE). However, at 3M the mean sinus heart rate was significantly lower in patients with compared to patients without recurrences (p = 0.031). In this regard, patients with a heart rate change < 11bpm (PRE to 3M) or, as an alternative parameter, patients with a heart rate < 60bpm at 3M had a significantly higher risk of recurrences compared to the remaining patients (Hazard ratio (HR) 1.82 (95% CI 1.32-2.49), p < 0.001 and HR 1.64 (95% CI 1.20-2.25), p = 0.002, respectively).

Our study confirms the impact of PVI on cardiac autonomic function with a significant sinus heart rate increase post-ablation. Patients with a sinus heart rate change < 11bpm (PRE to 3M) are at higher risk for recurrences during one-year post-PVI.

To compare bony nasolacrimal duct anatomy between ethnic groups.

A retrospective observational study of patients of four ethnic groups who had high-resolution CTs between 2004 and 2019 covering the full length of their nasolacrimal ducts in two hospitals in Essex, England. Only normal ducts were included; patients with tearing or radiological abnormalities were excluded. Measurements were taken of the nasolacrimal duct and surrounding anatomy based on measurements found in the existing literature.

More females (n = 114) than males (n = 40) were included. South Asian (Indian subcontinent), Afro-Caribbean and European groups were equivocal demographically (n = 25-29, mean age 40-45); however, the Oriental group was fewer in number (n = 13) and slightly older (mean age 51). South Asian and European ducts had no significant differences. Afro-Caribbean ducts were wider and shorter than European. Avexitide manufacturer Afro-Caribbean faces are wider and their noses flatter and wider than European. Oriental ducts were wider and longer than European, but Europeans have taller noses.
