Astigmatism is a refractive condition encountered commonly in clinical practice. This review presents an overview of research that has been carried out examining various aspects of this refractive error. We examine the components of astigmatism and the research into the prevalence and natural course of astigmatic refractive errors throughout life. The prevalence of astigmatism in various ethnic groups and diseases and syndromes is also discussed. We highlight the extensive investigations that… 
Physiology of Astigmatism
TLDR
Factors that determine baseline, diurnal, functional, and dynamic aspects of ‘physiological astigmatism’ are focused on.
Ocular residual and corneal astigmatism in a clinical population of high school students
TLDR
ORA is common in high school students and usually demonstrates a compensation relationship with CA, which should be taken into consideration when determining the design of contact lenses to correct refractive error.
An Ayurveda Approach to the Management of Astigmatism: A Case Report
TLDR
A female subject aged 10 years, diagnosed with myopic astigmatism, was treated with Nasya, Aschothana, Seka, Pindi and Tarpana and there was significant improvement in both parameters which highlights the benefits of Kriyakalpas in myopic Astigmatism.
A collection of studies on the biometry of myopic and non-myopic eyes
TLDR
It is recommended that normative refractive, astigmatism and axial length data should be tailored to individual characteristics, and pilot work suggests that Retinitis Pigmentosa and Congenital Stationary Night Blindness are appropriate models for the investigation of the retinal periphery’s role in myopia development.
Investigation of the Similarity and Symmetry Patterns of Astigmatism Axes in Refractive Surgery Candidates
TLDR
Isorule astigmatism is a very common pattern in refractive surgery candidates and anisorule asthma is a rare condition and there was a higher tendency towards mirror symmetry compared to direct symmetry in this study.
Characteristics of Astigmatism as a Function of Age in a Hong Kong Clinical Population
TLDR
In this Hong Kong Chinese clinical population, the prevalence rates of both myopia and astigmatism increased during the first three decades and shared a similar trend before the age of 50 years, indicating that the shift toward more ATRAstigmatism was related to corneal change.
Correlation between the pattern of myopic fundal changes and the axis of astigmatism of the eye
TLDR
Astigmatism is likely to have an aetiopathogenic association with myopic fundal changes, and this study found a statistically significant correlation between this axis and the long axis of myopic retinal degeneration.
Corneal and Refractive Astigmatism in Adults: A Power Vectors Analysis
TLDR
This vector-based approach is equivalent to the traditional Javal rule, but it has the ability to make predictions about oblique astigmatism, rendering it more general and more accurate.
The prevalence and progression of astimatism and myopia in children
TLDR
Progression of astigmatism and myopia were not linked, suggesting that whilst they may share some risk factors, they appear to be independent of one another.

TLDR
One objective of the study was to discover if a statistically significant difference existed between right and left eyes when comparing the mean correcting minus cylinder axes for WTR, ATR, and oblique types of astigmatism.

Astigmatic axis and amblyopia in childhood.
TLDR
The results accord with earlier findings that oblique astigmatism increases the risk of developing amblyopia and the angle of the astigmatic axis strongly relates to therisk of developing Amblyopia.

TLDR
Astigmatism was common in early infancy but decreased in prevalence with age, particularly when with-the-rule in orientation, and the corneal and anterior lens surface became more spherical withAge, contributing to the shift away from with- the-rule refractive astigmatism.
The Association of Astigmatism and Spherical Refractive Error in a High Myopia Cohort
TLDR
In severely myopic patients, there is a high prevalence of astigmatism that is predominantly with-the-rule, and the degree of myopic spherical refractive error is correlated withAstigmatism severity but is not a risk factor for the presence of astigmaticism.
Natural and imposed astigmatism and their relation to emmetropization in the chick.
TLDR
The lack of significant astigmatic changes with accommodation-stimulating and inhibiting drugs (nicotine and vercuronium resp.), for normal chicks, implies that accommodation, while the most likely mechanism for astigmatism, has little capacity to compensate for imposed astigmatic focussing errors.
Astigmatism and its components in 6-year-old children.
TLDR
The data suggest that emmetropization for RA occurs by a compensatory process between CA and IA, and East Asian and South Asian children had significantly greater prevalence and mean RA and CA than European Caucasian children.

TLDR
The astigmatic frequency distribution was quantified statistically and mild correlations were found between total and corneal astigmatism and may be of interest to those investigating refractive-error development.

TLDR
Findings contradict commonly held clinical impressions regarding the symmetry of astigmatic axes, and should be considered when performing statistical analysis of astigmatism data.
Correlation Between Pterygium Size and Induced Corneal Astigmatism
TLDR
Once pterygia reach a critical size, they induce visually significant central with-the-rule astigmatic changes that may not be apparent by subjective refraction, which helps to identify those patients who may benefit from surgical intervention.
