Visual performance in high myopia
Current Eye Research, 1990The visual performances of eight low myopic subjects (-2 D to -7 D) and eight high myopic subjects (greater than -7 D) with normal visual acuities were analyzed by contrast sensitivity testing with both spectacle and contact lens corrections to determine if any differences in function exist between those groups.

Posterior segment conditions associated with myopia and high myopia
Clinical and Experimental Optometry, 2020Myopia, and especially high myopia, is associated with a number of posterior segment changes that are considered to be mostly a consequence of the increased axial elongation. This can result in mechanical strain, attendant vascular changes, stretching and thinning of tissues, and atrophy/deformation of tissues in later or more advanced stages.

SummaryUrbanisation and increasing of education of modern societies is influencing normal homeostasis of eye growth, which in turn is causing an important myopic shift. Myopia is associated with increased vitreous liquefaction and premature synchisis and syneresis of the vitreous body.

High myopia and cataract surgery
Current Opinion in Ophthalmology, 2016Cataract surgery in high myopes is challenging. Using third-generation intraocular lens (IOL) formulas, without adjustments, hyperopic refractive outcomes are common. We discuss these issues, focusing on the various lens formulas and transformations that have improved postoperative accuracy.Axial length measurement error has been largely overcome by ...

High myopia with cone dysfunction
Acta Ophthalmologica, 1991Abstract. All 3 children, 2 boys and 1 girl (the probands), in a family had high myopia and subnormal visual acuities. The boys had high myopia in both eyes, the girl had high myopia in 1 eye and low myopia in the other eye. Both of the boys had a protanomalous colour vision defect.

Esotropia associated with high myopia
Current Opinion in Ophthalmology, 2015The aim of the present article is to describe the pathophysiology of esotropia associated with high myopia, commonly known as heavy eye syndrome, and discuss the preoperative evaluation and surgical options in these complex patients.Numerous studies have looked to determine the cause of esotropia in patients with high myopia.

Clinical Results in High Myopia
2015Small incision lenticule extraction (SMILE) is an all-femtosecond laser treatment for refractive errors. In contrast to previous flap-based treatment, a thin layer of anterior stroma is preserved during SMILE surgery. This has led to the suggestion that SMILE has a higher biomechanical stability than excimer laser based photoablative procedures ...

Peripapillary Atrophy in High Myopia
Current Eye Research, 2017To evaluate peripapillary atrophy (PPA) in high myopia (HM) as a function of extent of myopia, axial length (AL), and age.Medical records from patients (n = 88) seen in the Ophthalmology Department of the Third Affiliated Hospital of Nanchang University, Nanchang, Jiangxi, China, and diagnosed with high myopia (HM)-defined as spherical equivalent (SE ...

Myopia-Related Fundus Changes in Singapore Adults With High Myopia
American Journal of Ophthalmology, 2013To examine the pattern of myopia-related macular and optic disc changes in Singapore adults with high myopia (spherical equivalent ≤-6.00 diopters).Asian adults with high myopia from 3 population-based surveys.Adults 40 years and older (n = 359) with high myopia were pooled from 3 population-based surveys in Singapore Asians: (1) the Singapore ...
