Diplopia in high myopia

Expert Review of Ophthalmology, 2016
ABSTRACTIntroduction: Myopes often have double vision (diplopia) which could be monocular (uniocular) or binocular in origin. The prevalence and magnitude of myopia is significantly increasing in many parts of the world, often termed as myopia explosion.Areas covered: Different etio-pathogeneis and mechanisms resulting in diplopia in myopes is ...

Visual performance in high myopia

Current Eye Research, 1990
The 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.

Myopia and high myopia ‐ genetics and environmental factors

Acta Ophthalmologica, 2014
AbstractPrevention of myopia is now urgent, since there is an epidemic of high myopia, as well as ordinary myopia, in East Asia. The prevalence of high myopia is now around 20%, compared to about 1% in older generations. This new, acquired, high myopia has an unusual developmental pattern, sitting at around 1% up to the age of 11‐13, and then ...

Posterior segment conditions associated with myopia and high myopia

Clinical and Experimental Optometry, 2020
Myopia, 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.

High myopia with cone dysfunction

Acta Ophthalmologica, 1991
Abstract. 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.

High Myopia

2017
The choroid plays an important role in the physiology and pathology of high myopic eyes. The choroid has been demonstrated to be thinner in high myopia comparing to control patients and also has a different profile, having thicker choroid in the temporal side of the macula.

Clinical Results in High Myopia

2015
Small 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 ...
