A new analysis of recent eye health studies shows that more time spent outdoors is related to reduced rates of nearsightedness in children and adolescents. Exposure to natural light and looking at distant objects may be key factors.
Researchers at Ben-Gurion University have identified the LEPREL1 gene as causing myopia by affecting collagen modification in the eyes. This discovery may lead to better understanding and prevention of nearsightedness.
Earl Smith, University of Houston's Dean of Optometry, has developed a treatment strategy to slow the progression of myopia in children. His team is partnering with researchers in Australia to develop new contact lenses that can be used to implement these strategies.
Smith's breakthrough discovery involves new technologies to control myopia progression through peripheral optics manipulation, which can slow disease progression and mitigate vision loss. His work aims to provide practical implications for clinical management of myopia and offers a fundamental shift in optical interventions.
Scientists at Duke University Medical Center have identified a gene associated with myopia in Caucasian people, providing new hope for gene therapies. The RASGRF1 gene plays a crucial role in retinal function and visual memory consolidation, making it a promising target for treatment.
A new study found that higher body weight is significantly linked to reduced risk of normal tension glaucoma (NTG) in postmenopausal women, but not in men. Severe myopia may be predicted by a specific map that identifies patients at risk of vision loss.
A new Cochrane Systematic Review suggests phakic intraocular lenses (IOLs) may be a safer alternative to excimer laser surgery for moderate to high levels of short-sightedness. Patients who underwent IOL treatment reported better spectacle-corrected vision and contrast sensitivity, as well as higher patient satisfaction.
A new study published in the American Journal of Ophthalmology found that 90% of children with intermittent exotropia will become nearsighted by age 20. Researchers followed 135 patients over a 20-year period and discovered a significantly higher rate of myopia development in this population compared to previously reported rates.
A new study found that bifocal glasses can slow the progression of nearsightedness in children. The treatment was more effective than single-vision lenses and had a significant role in preventing the development of very high pathologic myopia.
Researchers found a statistically significant increase in myopia prevalence among US participants from 1971 to 2004, with higher rates observed in younger individuals. The study suggests that modifiable risk factors for myopia development could lead to the creation of cost-effective intervention strategies.
A study published in Archives of Ophthalmology found that collagen copolymer lens implantation is effective in correcting moderate to high myopia over four years. The procedure has been shown to provide stable correction with minimal complications, but longer-term follow-up is necessary to assess potential late-onset issues.
A study published in the Journal of AAPOS found that pirenzepine gel can slow the rate of progressive myopia in children, with an average increase of 0.58 diopters over two years compared to 0.99 diopters in the placebo group. The treatment was generally safe and effective, with only mild side effects reported.
A new study published in Ophthalmology reveals that Asian men are at a higher risk of developing age-related macular degeneration (AMD) due to smoking. In contrast, high levels of outdoor activity in childhood may prevent or control myopia in children, according to researchers. These findings suggest that environmental factors play a s...
Studies among Ophthalmology's April 2008 issue highlight the potential link between natural light exposure before birth and the development of myopia. Researchers also examine the suitability of older donor corneas for transplant surgery, finding that those from donors aged 66-75 have comparable quality to younger donors.
Myopia research reveals no link between glasses-wearing and introversion, but a small association with Agreeableness; good eye care is key, dispelling preconceived notions about wearing glasses
A study of 196 high myopic eyes found LASIK to be a safe and effective procedure in the long term. The results showed that 40% of patients avoided wearing glasses after surgery, while only 5% lost more than 2 lines of vision.
A new study found that children with two myopic parents wearing progressive-addition lenses showed slower myopia progression compared to those wearing single-vision lenses. The five-year study identified parental refractive error as a key factor in myopia progression, suggesting that special lenses may be beneficial for certain children.
Researchers found that the feedback system regulating eye growth doesn't consider all spatial frequencies and only focuses on the finest detail present. This discovery has implications for the development of myopia and suggests that images of low contrast can be just as effective at initiating growth as blurred images.
A three-year study found that rigid gas permeable contact lenses slowed the progression of myopia by nearly 30 percent in nearsighted children. The study, which included over 100 children aged 8-11, showed that RGP lenses altered the shape of the cornea and reduced 'corneal steepening', a condition associated with nearsightedness.
The study found that nearly 60% of patients achieved 20/20 or better visual acuity after three years, while reports of symptoms decreased. The ICL was more effective than LASIK for patients with higher degrees of myopia.
The study found that approximately one-third of people older than 40 experience vision disturbances, with myopia being the most prevalent eye disorder. The estimated prevalence rates for myopia vary by region, affecting about one in four people in the US and Western Europe, and one in six Australians.
OXiGENE has expanded its research and development program in ophthalmology following a significant improvement in a patient with myopic macular degeneration. The patient's vision was restored to 20/20 after treatment with CA4P, a vascular targeting agent.
Research suggests that children who spend more time studying and reading are more likely to develop myopia. However, the study found no link between screen time and the development of myopia. The study of 366 eighth-grade children highlights the importance of hereditary factors in the development of myopia.
A new study published in Nature found no association between nighttime lighting and the development of nearsightedness in children. The study surveyed over 1,200 children and found that parents' eye sight and genetics played a more significant role in causing myopia.
Children who slept with a night light on before age 2 are at significantly higher risk of developing myopia, with 34% affected compared to 10% who slept in darkness. Eliminating nighttime lighting exposure during early childhood may affect the development of this common form of refractive error.
Researchers at Emory University Health Sciences Center discovered that the visual experience of one eye influences the growth and quality of vision in the fellow eye. The study found that environmental factors play a significant role in eye development, suggesting a potential cure for myopia and related eye problems.
