Significance of Astigmatism
Astigmatism, as described in the text, is a refractive error impacting vision. It occurs when light doesn't focus evenly on the retina, resulting in blurred or distorted vision. This condition is often caused by an irregular eye shape. It can affect children and is associated with conditions like Keratoconus and Pterygium. Various studies assess Astigmatism as an objective criteria, with treatments sometimes showing limited success in reducing its effects.

Hindu concept of 'Astigmatism'
In Hinduism, astigmatism, a refractive error, causes blurred vision due to irregular eye meridians. It was assessed in a study, linked to Keratoconus, and found in children, where treatment reduced it.

(1) This is a refractive error, which was reduced after treatment, and is an important parameter in the cornea, which was measured before and after treatment.[1] (2) Astigmatism is an objective criteria that was assessed in the study, and Guduchyadi Rasakriya Anjana was not significant in decreasing this condition.[2] (3) This is a condition, which is irregular, and it is associated with Keratoconus, and causes defective vision, as mentioned in the provided text.[3] (4) Astigmatism is a refractive error that leads to blurred vision due to varying refraction in different meridians of the eye.[4]

(1) Astigmatism, a type of refractive error, was the specific condition diagnosed in the 9-year-old child in the case report, and is often found in children.[5]
The concept of Astigmatism in scientific sources
Astigmatism is a prevalent vision issue marked by blurred or distorted sight. It arises from an irregularly shaped eye, preventing light from focusing properly on the retina. Often linked to refractive errors, it may be worsened by other conditions and can complicate vision correction.
From: The Malaysian Journal of Medical Sciences
(1) A refractive error where the eye does not focus light evenly, often caused by a pterygium, and it is a major visual problem.[6] (2) This is a refractive error where the eye does not focus light evenly on the retina. Children with this may not be reliably detected.[7] (3) A common pre-existing condition that can affect the accuracy of intraocular lens power calculations and can also cause a significant refractive error after cataract surgery if not adequately addressed.[8]
