Myopia describes a refractive condition of the eye in which light rays are focused in front of the retina and is typically associated with axial elongation. The prevalence of myopia ranges from 0.8% to 75% in various population surveys. It has the highest prevalence in Asian populations. Myopia is associated with an increased risk of cataracts, glaucoma, macular degeneration, choroidal neovascularization, peripheral retinal degeneration and retinal detachment. Myopia may also be associated with abnormal ocular mobility. Strabismus associated with myopia can present in a variety of ways. In this review article, we will discuss the issues related to ocular motility disorders in pathologic myopic patients known as myopic strabismus fixus.

High myopia: Reviews of myopia control strategies and myopia complications

January 2025 · Acta Ophthalmologica

Aims: Most participants in myopia control studies have low and moderate myopia, relatively little is known about myopia control in high myopia. This review aims to evaluate the efficacy of myopia control strategies in high myopia and report on the structural and pathological complications of the eye. Methods: Comprehensive literature searches were undertaken using keywords in MEDLINE and EMBASE ... [Show full abstract] to identify publications in English, evaluating (1) the efficacy of myopia control strategies (environmental, pharmacological and optical) in high myopia (≤‐6.00D) and (2) the complications of high myopia. Outcomes include change in spherical error (SE) and/or axial length (AL) to evaluate progression in high myopia. Results: Twelve studies evaluating the efficacy of optical and pharmacological (none on environmental) interventions on axial elongation and myopic refractive error for high myopia control were identified. A statistically significant reduction in progression of refractive error in high myopes was reported with 1% and 0.5% atropine. Defocus Incorporated Multiple Segment spectacle lenses had lower efficacy in slowing high myopia progression compared to moderate and low myopia. Ortho‐K lenses were equally effective in reducing myopia progression in low, moderate and high myopia. All myopic patients have an increased risk of myopic macular degeneration, retinal detachment, cataract and glaucoma; with the risk increasing with level of myopia. Conclusions: High myopia has significant effects on quality of life and risk of pathological complications and vision impairment. Young children, excluding those with some syndromic associations, who are fast progressing moderate and high myopes require early intervention and close monitoring. Further research investigating the efficacy of myopia control strategies in highly myopic patients, both monotherapies and combination treatments, are necessary.

PREVALENCE OF MYOPIA IN PRESCHOOL CHILDREN IN RADOVISH

September 2018 · Knowledge International Journal

Аbstract: Myopia or nearsightedness is a refractory anomaly where parallel light rays entering the eye after breaking through the cornea and lens congregate with a focus that is in front of the retina in the vitreous body rather than falling to the retina at a clear-sighted center where the light rays are diverging and making a sculpted image of the object that the eye is currently ... [Show full abstract] observing. Myopia is a refractory error with multifactorial aetiology, occurs in 50% of the population in the intestinal countries and this percentage is expected to increase in the future, complications associated with axial elongation from myopia are the sixth leading cause of blindness. Knowing its mechanism, etiology, epidemiology and the results of various therapeutic methods can modify current care and result in decreasing morbidity from progressive myopia. The exact etiology of myopia is still unclear is considered to have a genetic and environmental or social component that makes prevention and treatment challenging and individual. Axial lengthening of the eye can not be explained only by genetics. Current animal and human studies show that the development of myopia is the result of interactions between genetic and environmental factors. The occurrence of myopia is higher in persons whose two parents are myopic, which suggests that genetic factors are clearly involved in the development of myopia. At the same time, research in the population shows that the development of myopia is associated with education and the time they spend watching the proximity at work. Hence, increased proximity activities cause optical blurring and fatigue. Efforts to slow the progression of myopia are enormous due to its relationship to the development of serious pathological conditions such as macular degeneration, retinal detachment, glaucoma and cataracts. Considering the pathological complications of myopia and other serious pathological conditions associated with the disease, myopia not only negatively affects self-perception, the work or the choice of a working profession in proportion to the ocular health condition, it is also one of the leading causes of blindness in the world. It is estimated that by the year 2050 a sail of the light population will have a refractory anomaly-myopia. Keywords: myopia,axial elongation, refractory anomaly
