Effect of interactive, multimedia-based home-initiated education on preoperative anxiety inchildren and their parents: a single-center randomized controlled trial.

Background: Anesthesiologists need to appreciate the impact of preoperative anxiety in children. The present study aimed to explore whether interactive multimedia-based home-initiated interventions could effectively relieve preoperative anxiety in pediatric patients.

Methods: In this prospective study, we compared preoperative anxiety between two groups of children aged 4-9 years.

OUTER RETINAL TUBULATION IN BIETTI CRYSTALLINE DYSTROPHY ASSOCIATED WITH THE RETINAL PIGMENT EPITHELIUM ATROPHY.

Purpose: To determine the prognostic value of outer retinal tubulation (ORT) in the eyes of a Chinese cohort with Bietti crystalline dystrophy (BCD).

Methods: This retrospective, multicenter cohort study enrolled 42 patients with clinically and genetically diagnosed BCD. Eighty eyes with good-quality images of spectral domain optical coherence tomography were included.

Permanent Visual Impairment due to Delayed Diagnosis of Shunt Malfunction in Case of Lack of Typical Features of Increased Intracranial Pressure and Unchanged Ventricular Size.

Objective: We present the clinical features, imaging, and management of 5 cases of visual impairment as the primary manifestation ventriculoperitoneal (V-P) shunt malfunction.

Methods: We retrospectively reviewed the medical records of 126 patients of V-P shunt malfunction in Shanghai Children's Medical Center between 2015 and 2020. Medical records including all hospital admissions were reviewed and follow-up data were collected.

Axial length/corneal radius of curvature ratio and refractive development evaluation in 3- to 4-year-old children: the Shanghai Pudong Eye Study.

Aim: To measure and analysis axial length (AL)/corneal radius of curvature (CRC) ratio and other refractive parameters, provide a medical reference range for refractive development evaluation and earlier visual impairment screening of 3 to 4y kindergarten students.

Methods: Between April and June 2017, a total of 4350 participants aged 3- to 4-year-old (8700 eyes) from 10 cluster random sampling kindergartens in Shanghai, Pudong District were involved. According to the measurement and analysis of the unaided visual acuity (VA), AL, CRC, AL/CRC ratio, astigmatism and other refractive parameters, the data distribution and reference range were obtained.
