Impact of Free Glasses and a Teacher Incentive on Children's Use of Eyeglasses: A Cluster-Randomized Controlled Trial.

Purpose: To study the effect of free glasses combined with teacher incentives on in-school glasses wear among Chinese urban migrant children.

Design: Cluster-randomized controlled trial.

Methods: Children with visual acuity (VA) ≤6/12 in either eye owing to refractive error in 94 randomly chosen primary schools underwent randomization by school to receive free glasses, education on their use, and a teacher incentive (Intervention), or glasses prescriptions only (Control).

Vision-related Quality of Life Outcomes of Cataract Surgery in Advanced Glaucoma Patients.

Purpose: To demonstrate longitudinal postoperative vision-related quality of life and visual acuity changes after cataract surgery in advanced glaucoma patients.

Materials And Methods: In total, 93 patients who underwent cataract surgeries were collected from June 2010 through June 2013 in Shanghai First People's Hospital, Shanghai Jiao Tong University, and were followed up for at least 3 months. Patients with advanced glaucoma, here defined as near total cupping of the optic nerve with severe visual field loss within 10 degrees of fixation, were enrolled.

A five-year prospective study of diabetic retinopathy progression in chinese type 2 diabetes patients with "well-controlled" blood glucose.

Purpose: To determine the progression rate and risk factors for diabetic retinopathy (DR) in Chinese type 2 diabetic patients who have reached the target hemoglobin A1c (HbA1c) level recommended by the American Diabetes Association.

Methods: This was a 5-year community-based prospective study. The study population consisted of patients with type 2 diabetes with HbA1c less than 7.

Screening for significant refractive error using a combination of distance visual acuity and near visual acuity.

Purpose: To explore the effectiveness of using a series of tests combining near visual acuity (NVA) and distance visual acuity (DVA) for large-scale screenings for significant refractive error (SRE) in primary school children.

Method: Each participant underwent DVA, NVA and cycloplegic autorefraction measurements. SREs, including high myopia, high hyperopia and high astigmatism were analyzed.

Prevalence and causes of visual impairment and rate of wearing spectacles in schools for children of migrant workers in Shanghai, China.

Background: To assess the prevalence of visual impairment and rate of wearing spectacles in schools for children of migrant workers in Shanghai, China.

Methods: Children from grade 1 to 5 in schools for children of migrant workers were randomly chosen for ocular examinations. All children were screened for uncorrected visual acuity and presenting visual acuity.

The 5-year onset and regression of diabetic retinopathy in Chinese type 2 diabetes patients.

Purpose: To determine the rate and risk factors of diabetic retinopathy (DR) onset and regression in Chinese type 2 diabetes mellitus patients.

Methods: This is a 5-year community-based prospective study. The demographic information, systemic examination results and ophthalmological test results of each participant were collected.

[Prevalence of primary glaucoma among adults aged 50 years or above population in Huamu community: a cross-sectional survey in Shanghai, 2011].

Objective: To investigate the prevalence and characteristics of primary glaucoma in the population of Huamu community, Shanghai.

Methods: It was a population-based cross-section study.Using random cluster sampling method, 3 neighborhood committees were randomly selected from Huamu community.

[The impact of amplitude of accommodation on controlling the development of myopia in orthokeratology].

Objective: To evaluate the impact of amplitude of accommodation on controlling the development of myopia in orthokeratology.

Methods: Forty-nine children aged 7 to 14 years were enrolled in this prospective clinical study.Orthokeratology was performed to correct the refractive errors of these children after measurement of refraction, corneal topography, amplitude of accommodation and axial length.

Myopia screening: combining visual acuity and noncycloplegic autorefraction.

Purpose: To explore the effectiveness of combining uncorrected visual acuity (UCVA) and noncycloplegic autorefraction (NCAR) for large-scale myopia screening in schoolchildren with a high prevalence of myopia.

Methods: A total of 1687 children aged between 6 and 12 years, from five primary schools in the Baoshan district of Shanghai participated in the study. We measured UCVA and autorefraction before and after cycloplegia by a Topcon KR-8800.

Visual impairment and spectacle coverage rate in Baoshan district, China: population-based study.

Background: To investigate the prevalence and risk factors of visual impairment associated with refractive error and the unmet need for spectacles in a special suburban senior population in Baoshan District of Shanghai, one of several rural areas undergoing a transition from rural to urban area, where data of visual impairment are limited.

Methods: The study was a population based survey of 4545 Chinese aged (age: >60 years or older ) at Baoshan, Shanghai, in 2009. One copy of questionnaire was completed for each subject.
