Objective: To investigate the impact of using orthokeratology lenses (OK lenses) for one year on the axial length (AL) and choroidal thickness (ChT) in the 6 mm concentric central retinal region.
Methods: 36 myopic children (36 eyes) aged 8 to 16 years were enrolled. For the duration of one year, the OK group (18 subjects) utilized OK lenses, while the spectacles group (18 subjects) utilized single-vision spectacles as a control.
Purpose: The goal of this study was to compare the difference in binocular visual function for high and low-moderate myopes before and after femtosecond laser-assisted in situ keratomileusis (FS-LASIK).
Methods: Thirty-three subjects (17 males and 16 females) were divided into two groups according to their preoperative refractive errors in spherical equivalent (SE): low-moderate myopia group (SE ≥-6.00 D) and high myopia group (SE <-6.
Article Synopsis
- The Shantou Myopia Study aimed to assess the prevalence and risk factors for myopia in schoolchildren in southern China, involving over 724,000 students.
- It found that 51.8% of participants had myopia, with the rates increasing significantly with age and in urban environments, along with notable differences between education levels.
- Additionally, around 60% of those with myopia were uncorrected, highlighting a critical need for eye care education in schools.
Background: Booster doses could play a major role in no responders or low responders to primary hepatitis B (HB) vaccine. Planed time point for hepatitis A vaccination in China provides a good opportunity to carry out HB booster dose by using combined hepatitis A and B vaccine.
Methods: A randomized, double-blinded clinical trial was conducted to compare the immunogenicity and safety of toddlers 18-24 months of age receiving 3 different vaccination regimens: 2 doses of inactivated hepatitis A vaccine (group 1), 1 dose of inactivated hepatitis A vaccine plus 1 dose of combined hepatitis A and B vaccine (group 2) or 2 doses of combined hepatitis A and B vaccine (group 3).
