Active clinical trials for "Myopia"

In 2020, the overall myopia rate among children and adolescents was 52.7% in China. The COVID-19 pandemic has increased students' time of indoor eye-using, and it showed that the light exposure intensity of myopic students is lower than that of non-myopia students. Studies have found that in addition to exposure to light intensity, the occurrence and development of myopia is also related to the color temperature and wavelength band of light. The sun-like spectrum refers to the spectrum with continuous wavelength bands. Animal experiments suggest that sun-like artificial lighting can prevent myopia, but the relationship between sun-like artificial lighting with different color temperatures and myopia is unknown. Clinical trials suggest that artificial lighting with a sun-like spectrum can delay fundus blood flow decline. One hypothesis is that reduced choroidal blood flow leads to scleral hypoxia and promotes the development of myopia. This study aims at comparing the effects of sun-like spectrum artificial lighting with different dominant wavelengths on the human eye, and providing clues for the prevention and control of myopia.

Myopia (nearsightedness) is increasing in prevalence throughout the world. It is associated with a risk of potentially blinding complications such as retinal detachment and myopic maculopathy. There is a direct association between the degree of myopia and the risk of complications. Myopia develops in childhood and during adolescence. To prevent higher degrees of myopia, we need to halt disease progression in children and teenagers. Low-dose atropine eye drops have been shown to reduce myopia progression by 50% in Asian populations but its effect in non-Asian populations is unknown. The aim of this study is to investigate if low-dose atropine can reduce myopia progression in Danish children and teenagers. The study is an investigator initiated randomized clinical trial conducted as a collaboration between three Danish Eye Departments covering all of Denmark.

Short-sightedness, also called myopia, makes objects in the distance, such as the television, look blurred. This is caused by the eye growing too long, something that usually happens while children are also getting taller. People with myopia can see better with glasses or contact lenses, but this doesn't stop their eyes continuing to become more short-sighted. The CHAMP UK study is investigating a type of eye drop called atropine that might help to stop myopia getting worse as children get older.

This project intends to provide important, previously unmet answers regarding biological associations with myopia (nearsightedness) progression in order to improve the ability to predict patients who are most likely to benefit from myopia control, as well as questions frequently posed by patients and practitioners about the side effects, mechanism, and discontinuation of soft bifocal contact lens myopia control. The first three aims examine the association between biological variables that can be measured non-invasively and myopia progression, and they will be conducted regardless of the outcome of the currently in progress BLINK Study. The last three specific aims will be conducted if soft bifocal contact lenses slowed myopia progression by 30% or more in the BLINK Study, and they can be investigated with very few additional measurements.

Randomized, controlled, multisite, subject-and observer-masked, 3-arm parallel group clinical trial of 36-month duration to evaluate the safety and efficacy of a novel spectacle lens design in reducing the progression of juvenile myopia.

The two-year prospective study aims at investigating frequently replacement effect on myopia control in young children, and the use of weekly protein removal system in monthly replacement modality orthokeratology lenses on surface deposit.

Myopia prevalence has dramatically increased worldwide in recent years in the general population and among children. Progressive myopia increases gradually with growth until the age of 20-25 years. At the same time, there is a remarkable increase in the prevalence of severe myopia (more than -6 diopters). Severe myopia is associated with many complications, which can lead to blindness. There is thus an increase in the number of myopic patients in general, and severe myopic patients in particular. The management of myopia and its complications is therefore a major public health issue. All the means likely to slow the evolution of myopia (thus to limit the prevalence of strong myopia) must be developed to limit the consequences. 0.01% Atropine seems to be a drug with a great interest to slow down the progression of myopia. The aim of the present study is to evaluate the efficacy at 1 year of 0.01% atropine (1 drop per day administered for 1 year) on the reduction of fast progressing myopia in children aged 4 to 12, compared to a control group (instillation of a placebo).

The purpose of this trial is evaluating the clinical effect of a myopia control spectacle lens compared to a single vision spectacle lens in slowing down the progression of myopia in children living in Israel.

The two-year prospective study aims at investigating the benefits of frequent replacement (monthly) orthokeratology lenses in myopia control in terms of effectiveness in control and prevention of ocular complications. The secondary objective will be investigating the use of weekly protein removal system in monthly replacement modality orthokeratology lenses on surface deposit.

This is an open-label, controlled, multisite, two-arm parallel group clinical trial of 36-month duration to evaluate the continued safety and efficacy of SightGlass Vision Diffusion Optics Technology (DOT) Spectacles in reducing the progression of juvenile myopia.
