Background: Thygeson's superficial punctate keratitis (TSPK) is reportedly a rare disease with an insidious onset, numerous remissions and exacerbations, and a long duration. The corneal lesions are elevated, whitish-grey in colour, and granular in the intraepithelium. A few reported cases of TSPK exist, and paediatric experience is limited.

Methods: From January 2009 to February 2011, premature babies receiving fundus photographic screening (FPS) were recruited and divided into non-ROP group and ROP group. Full-term babies matched in age were recruited as controls.
Diabetic retinopathy (DR) is the serious complication of type 2 diabetes mellitus, which could lead to visual impairment. Growing evidence have revealed the involvement of long non-coding RNAs (lncRNAs) in the pathogenesis of DR. Thus, this study was performed to investigate the role of lncRNA SNHG7 (small nucleolar RNA host gene 7) in high glucose (HG)-induced proliferation, migration, and angiogenesis of human retinal endothelial cells (hRECs).

Methods: Ninety-six C57BL/6J mice were selected and divided into the normal control group (n = 12) and the oxygen-induced retinopathy (OIR) group (n = 84). All the mice in the OIR group were assigned to the following seven groups (12 mice in each group): the blank, miR-29a mimics, miR-29a inhibitors, empty plasmid, miR-29a mimics + si-AGT, miR-29a inhibitors + si-AGT and si-AGT groups.
Purpose: To investigate the refractive status and optical components of premature babies with or without retinopathy of prematurity (ROP) at 3-4 years old, and to explore the influence of prematurity and ROP on the refractive status and optical components.
Methods: Premature babies receiving fundus examination were recruited into ROP group and non-ROP group, with age-matched full-term babies as controls.
Results: The incidence of myopia was the highest in ROP (3/59, 5.
Background: The aim of this study was to screen for retinopathy of prematurity (ROP) in southwestern China and understand the prevalence and risk factors of ROP, which may provide evidence useful in the prevention and treatment of ROP.
Material/methods: 1864 preterm infants (gestational age of <37 weeks and birth weight of ≤2500 g) underwent ROP screening from January 2009 to November 2012 in Southwest China. The medical information of infants during perinatal period was reviewed, and risk factors of ROP were determined.
Background: The present study investigated the prevalence of refractive error, visual impairment, and eye diseases in school-aged children in western China.
Methods: The survey was done in a representative county (Yongchuan District, Chongqing Municipality) of western China. Cluster random sampling was used to select children aged 6 to 15 years.
Objective: This study investigated the distribution pattern of refractive status and prevalence of refractive errors in school-age children in Western China to determine the possible environmental factors.
Methods: A random sampling strategy in geographically defined clusters was used to identify children aged 6-15 years in Yongchuan, a socio-economically representative area in Western China. We carried out a door-to-door survey and actual eye examinations, including visual acuity measurements, stereopsis examination, anterior segment and eyeball movements, fundus examinations, and cycloplegic retinoscopy with 1% cyclopentolate.
