Spherical Refractive Error

National Cancer Institute · Definitions · 2020

A measurement of the extent of defect in vision caused by a mismatch of optimal power between the cornea and/or lens and the length of the eyeball, resulting in sub-optimal reflection of light onto the retina.

Refractive error blindness

Dandona Rakhi, Dandona Lalit · SHILAP Revista de lepidopterología · 2001

Recent data suggest that a large number of people are blind in different parts of the world due to high refractive error because they are not using appropriate refractive correction. Refractive error as a cause of blindness has been recognized only recently with the increasing use of presenting visual acuity for defining blindness. In addition to blindness due to naturally occurring high refractive error, inadequate refractive correction of aphakia after cataract surgery is also a significant cause of blindness in developing countries. Blindness due to refractive error in any population suggests that eye care services in general in that population are inadequate since treatment of refractive error is perhaps the simplest and most effective form of eye care. Strategies such as vision screening programmes need to be implemented on a large scale to detect individuals suffering from refractive error blindness. Sufficient numbers of personnel to perform reasonable quality refraction need to be trained in developing countries. Also adequate infrastructure has to be developed in underserved areas of the world to facilitate the logistics of providing affordable reasonable-quality spectacles to individuals suffering from refractive error blindness. Long-term success in reducing refractive error blindness worldwide will require attention to these issues within the context of comprehensive approaches to reduce all causes of avoidable blindness.

Cylindrical Refractive Error

J. C. Bear, Avrum Richler · American journal of optometry and physiological optics · 1983

ABSTRACT The distribution of cylindrical refractive error (right eye only) is presented for 957 persons, comprising approximately 80% of the population (aged 5 years and over) of three western Newfoundland communities. In 72% of males and 60% of females no cylindrical error was found; 12% of males and 19% of females had errors greater than 0.5 D. Cylindrical errors of 2 D or greater were found in 2.5% of females but only 0.5% of males, affecting females of all ages but males aged less than 15 years only. Persons aged 45 years and up had fewer cylindrical errors, more against‐the‐rule and less with‐the‐rule astigmatism than persons below that age. Cylindrical error and spherical error, and in particular against‐the‐rule error and myopia, commonly occurred together. Among persons aged 5 to 14 years an association of with‐the‐rule error with nearwork is suggested.

Refractive error maps: A predictive tool for refractive error progression

Fabian Dębowy, Barbara Pierścionek · Ophthalmic and Physiological Optics · 2025

The concept of refractive error maps may provide more insight into the refractive state of individuals and groups with provision for a comparative analysis. With further experimental data added, such refractive error maps could be used as a predictive tool.

Refractive error and glaucoma

Kirsti Grødum, Anders Heijl, Bo Bengtsson · Acta Ophthalmologica Scandinavica · 2001

In this large population, the prevalence of glaucoma increased with increasing myopia. The association between myopia and glaucoma was strong at lower IOP levels, and weakened gradually with increasing IOP. Our findings indicate that myopia is an important risk factor for glaucoma and particularly for normal tension glaucoma.

Comparing Refractive Error with Axial Length in the Subjects Having Refractive Error

Jyoti Arora, Bhupinder Kaur Anand, Marwaha Manvinder Pal Singh et al. · International Journal of Contemporary Medical Research [IJCMR] · 2019

Refractive error has now become the second most common cause of blindness across the world. There is necessity to explore the various factors having impact on refractive errors as they will certainly assist in the various modes of treatment aspect of the refractive errors. This study was carried out with the aim of comparing refractive error with axial length in the subjects with refractive error.
