Background: Astigmatism is an abnormality within the curvature of the attention. It occurs when light rays strike a spherical lens obliquely, or the line of vision to its principal axis is not parallel. Refraction away from the axis occurs when light strikes a lens obliquely and distorts the image formed.
Aim: This study aimed to look at the prevalence of against-the-rule, with the-rule, and oblique-axis astigmatism in children. The change in cylinder index of refraction power and alignment of astigmatism in babies and young children is studied.
Methodology: To conduct the study and thoroughly search the literature separately, references and abstracts were reviewed. Books like Parson’s diseases of the Eye by Dr. Radhika Tandon and several articles, WHO website, etc., were referred.
Results: The study relied upon many studies on refractions procured by the near-retinoscopy methodology that knowledgeable Refractionist accomplished.
Conclusion: It can be concluded that young children have a high incidence of against (???) type of astigmatism and that after this age (which age?), most children are with the rule.
