Efficacy of the Euclid orthokeratology lens in slowing axial elongation

Contact Lens and Anterior Eye, 2023
The Euclid Emerald lens designs for orthokeratology have been available in global markets for over 20 years and is used extensively by clinicians for slowing myopia progression in children. This paper comprehensively reviews data from published studies of the efficacy of this lens.A comprehensive systematic search was performed in March 2023 using ...

Influence of Intraocular Pressure on Axial Elongation

Journal of Ocular Pharmacology and Therapeutics, 1990
The role of intraocular pressure (IOP) on axial elongation was studied by the following three experiments. 1) Thickness of the sclera in the lid-sutured-myopia of three monkeys was examined by light microscopy. The sclera of the experimental eye in the posterior pole was thinner than that of the control eye, but no differences were found in the ...

Factors associated with axial length elongation in high myopia in adults

International Journal of Ophthalmology, 2021
AIM: To investigate the association of axial length (AL) and ocular factors on AL elongation. METHODS: A retrospective chart review of patients who underwent two or more AL examinations for more than two years. Totally 4 groups were divided according to initial AL (<24 mm, 24-26 mm, 26-28 mm, ≥28 mm).

Elongation of Axial Blood Vessels with a Tissue Expander

Clinics in Plastic Surgery, 1987
The authors present a rat model and a surgical technique for the study of elongation of axial blood vessels using a tissue expander. The successful demonstration of elongation of axial vessels while maintaining patency further encourages use of the concept in other organ systems such as bowel, ureter, and so on.

Prevention of Axial Elongation in Myopia by the Trace Element Zinc

Biological Trace Element Research, 2001
The effect of the trace element zinc on the change in the axial length and diopters and the variations of activities of superoxide dismutase (SOD) and nitric oxide synthase (NOS), and the content of NO in the retino pigmental epithelium choroid homogenate of the myopic eyes in form-sense-deprived chicks were studied.

Effect of Orthokeratology on Axial Length Elongation in Anisomyopic Children

Optometry and Vision Science, 2019
SIGNIFICANCE Anisomyopia is a natural experimental paradigm that compares dose response between fellow eyes. This study is the first to explore whether orthokeratology (ortho‐k) has a dose‐response effect on axial length growth and reduces the interocular difference in axial length in anisomyopic children.

Persistent fetal vasculature presenting with axial elongation and platyphakia

Journal of American Association for Pediatric Ophthalmology and Strabismus, 2019
Leukocoria in children should always raise the concern for retinoblastoma. However, a variety of non-neoplastic conditions can also present with leukocoria, including persistent fetal vasculature (PFV), a nonhereditary, congenital anomaly caused by a failure of the fetal intraocular vasculature to regress during development.
