The Global Prevalence of Amblyopia in Children: A Systematic Review and Meta-Analysis.

Epidemiological data about the prevalence of amblyopia around the world vary widely among regions and periods. This meta-analysis aimed to determine the global prevalence of amblyopia in children. PubMed, Embase, and the Cochrane Library were searched for prevalence studies published up to 5 November 2021.

Consecutive contralateral comparison of toric and non-toric implantable collamer lenses V4c in vault after implantation for myopia and astigmatism.

Aims: To compare the vault performance between implantable collamer lens (ICL) V4c and Toric ICL (TICL) V4c after implantation and to investigate the affecting factors.

Methods: Sixty-eight eyes from 34 patients with myopia or myopia astigmatism who underwent implantation of TICL in one eye (group A) and identically sized ICL (group B) in the contralateral eye were included. Mean follow-up time were 7.

A huge lacrimal gland ductule dacryolith with a hairy nucleus: a case report.

Background: Dacryoliths in lacrimal gland ductule are a rare condition and an unusual cause of conjunctivitis. Here we report a case with a large lacrimal gland ductule stone with an unique hairy nucleus.

Case Presentation: A 38-year-old female presented with a red left eye for one month.

Effect of Limbal relaxing incisions during implantable collamer lens surgery.

Background: The limbal relaxing incisions (LRIs) technique is a safe and an inexpensive procedure, which is simple for experts to perform. It can effectively reduce astigmatism and result in a rapid visual rehabilitation. But there are few reports about reducing pre-existing corneal astigmatism by LRI in ICL surgery.

[Agreement and repeatability of central corneal thickness measurement using the Pentacam and ultrasound pachymetry].

Objective: To compare the agreement and repeatability of the OCULUS Pentacam (a new Scheimpflug-based imaging system) with ultrasound pachymetry in the measurement of central corneal thickness (CCT).

Methods: Central corneal thickness was measured in 112 subjects (112 eyes) separately by two examiners, first using the Pentacam instrument, then using an ultrasonic pachymetry. Measurements were repeated 3 times for each pachymetry.
