Purpose: To assess the development and enlargement of the parapapillary gamma zone in school children. Methods: This school-based prospective longitudinal study included Chinese children attending grade 1 in 2011 and returning for yearly follow-up examinations until 2016. These examinations consisted of a comprehensive ocular examination with biometry and color fundus photographs. The parents underwent a standardized interview. The parapapillary gamma zone was defined as the area with visible sclera at the temporal optic disc margin, and the optic disc itself was measured on fundus photographs...

AIM: To investigate the relationship between insulin resistance (IR)/β-cell dysfunction and diabetic retinopathy (DR) in Chinese patients with type 2 diabetes mellitus (T2DM), and to explore further whether there were differences in the relationship among diabetic patients with higher and lower body mass index (BMI). METHODS: Cross-sectional study. A total of 1466 subjects with T2DM were recruited in a local Desheng Community of urban Beijing from November 2009 to June 2012 for the cohort of Beijing Desheng Diabetic Eye Study...

PURPOSE: To assess changes in the optic disc-fovea distance (DFD) with progressing myopia in school children. METHODS: The school-based, prospective, longitudinal study included grade-1 children in 2011 who were yearly re-examined until 2016. We measured DFD, optic disc diameters and width of parapapillary gamma zone (parapapillary region without Bruch's membrane (BM)) on fundus photographs. RESULTS: Of 382 grade-1 children examined in 2011, 294 (77...

To examine associations between cognitive function and ophthalmological parameters, the population-based Beijing Eye Study examined ophthalmologically and physically 3127 individuals (mean age: 64.2 ± 9.8 years). Using the mini-mental state examination, cognitive function was assessed as cognitive function score (CFS). Mean CFS was 26.3 ± 3.7 (median: 27; range: 2-30). Prevalence of mild (CFS: 23-19), moderate (CFS: 18-10) and severe cognitive dysfunction was 9.6% (95% confidence interval (CI): 8...

To study macular choroidal layer thickness, 3187 study participants from the population-based Beijing Eye Study underwent spectral-domain optical coherence tomography with enhanced depth imaging for thickness measurements of the macular small-vessel layer, including the choriocapillaris, medium-sized choroidal vessel layer (Sattler's layer) and large choroidal vessel layer (Haller's layer). In multivariate analysis, greater thickness of all three choroidal layers was associated (all P < 0.05) with higher prevalence of age-related macular degeneration (AMD) (except for geographic atrophy), while it was not significantly (all P > 0...

PURPOSE: To examine frequency and associations of retinal hemorrhages. METHODS: The population-based Beijing Eye Study included 3,468 individuals. Monoscopic fundus photographs were examined for hemorrhages. RESULTS: Retinal hemorrhages were detected in 515 eyes (429 individuals) (prevalence: 7.6%; 95% confidence interval [CI]: 7.0-8.0 per eye; 12.7%; 95% CI: 11.7-13.7 per person). Higher prevalence of retinal hemorrhages was correlated (multivariate analysis) with higher systolic blood pressure (P < 0...

Objective: To compare the significance of contrast-enhanced ultrasound (CEUS) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in the diagnosis of uveal melanoma. Methods: It was a retrospective case series study. Sixty-three cases (63 eyes) of uveal melanoma patients (confirmed by histopathology) who underwent CEUS and DCE-MRI examination at Beijing Tongren Hospital during January 2010 and May 2014 were collected, including 30 males and 33 females, with average age of 47 years (ranged from 27 to 69 years)...

OBJECTIVE: Although local specific immunoglobulin (sIgE) has been employed as a diagnostic criterion for allergic rhinitis (AR), the use of local sIgE has not been fully evaluated in the diagnosis of allergic rhinitis. The aim of this study was to evaluate the use of nasal secretion sIgE in the diagnosis of allergic rhinitis. METHODS: A total of 51 patients (27 males and 24 females, mean age = 33.3 years) with rhinitis symptoms were enrolled consecutively from the allergy-rhinology clinic of Beijing TongRen Hospital (Beijing, People's Republic of China)...

COMPARATIVE STUDY
Yang Liu, Yingnan Zhang, Jing Zhang, Jin Yu, Qingfeng Liang, Zhiqiang Pan
Compared with evident cornea donors (ECDs), deceased potential cornea donors (DPCDs) have no obvious donor identifications to reference, which causes many eligible cornea tissues to be wasted. The demographic characteristics of DPCDs might be different from those of ECDs owing to the following different features: donation consent provided by relatives and willingness to donate before death. Thus, the aim of this study is to reveal the demographic characteristics of DPCDs by comparing DPCDs and ECDs.The demographic factors of 138 donors (both DPCDs and ECDs) were collected from the Beijing Tongren Hospital Eye Bank database and analyzed...

Objective: To examine the features and values of ultrasonic diagnosis for retinal detachment in eyes with silicone oil tamponade (SOT). Methods: A prospective study. A total of 257 eyes (257 patients) were filled with silicone oil between December 1, 2015 and August 1, 2016 in the Department of Ophthalmology at a hospital in Beijing. All of the patients underwent a color Doppler ultrasound examination in the supine and sitting positions a week prior to surgery. The pre-surgery conditions were compared with the subsequent observations during the surgery to analyze the features and values of ultrasonic diagnosis for retinal detachment in eyes with SOT...

BACKGROUND: Lack of willingness to pledge eyes among the general population is the main cause for the shortage of cornea tissue in China. A few studies have implied that general-population adults with specific demographics showed more willingness to donate their eyes. METHODS: In this study, we analyzed the demographic characteristics of 918 voluntary donors registered in Beijing Tongren Hospital Eye Bank in the past 10 years for possible predictors that might help us to identify potential donors in Beijing and increase the donation rate...

Based on the Beijing Eye Study 2011, a detailed ophthalmic examination was performed including spectral-domain optical coherence tomography (SD-OCT) with enhanced depth imaging for measurement of subfoveal choroidal thickness (SFCT) and relative height of posterior scleral staphyloma. OCT images were obtained in 103 highly myopic eyes (≤-6.00 diopters) and 227 normal eyes. The mean SFCT in highly myopic eyes was 110.6 ± 85.2 μm (range, 3 to 395 μm). The SFCT of high myopia without posterior scleral staphyloma(55 eyes) was 157...
