Comparitive clinical study on the effect of Mahatriphaladi
Ghrita Tarpana and Jeevantyadi Ghrita Tarpana in
Parathama Patalagata Timira w.r.t. Keratoconus

Keratonus is one of the important causes of progressive myopia and its incidence is 1 in 500 worldwide. Keratoconus is a degenerative disorder of the eye in which structural changes within the cornea cause it to thin and change to a more conical shape than the more normal gradual curve. Keratoconus typically starts at puberty as a progressive myopia causing substantial distortion of vision and marked astigmatism rapidly. This results in significant visual impairment leading to problems in doing routine works like driving and reading. Only temporary measures like Contact lenses and Surgery are available. In Ayurvedic terms, it can be correlated with Prathama Patalagata Timira. As Tarpana is considered to be supreme among all the Kriyakalpas in treating timira, it has been selected for the study. Giving due importance to the doshas and the site of pathology involved, Jeevantyadi Ghrita and Mahatriphaladi Ghrita are selected. Hence a clinical study has been done to compare the efficacies of Mahatriphaladi ghrita tarpana and Jeevantyadi Ghrita tarpana in Keratoconus.

Functional Changes

Aniridia affects many visual aspects of one’s life. This chapter will highlight many of these effects. Functional changes that occur due to aniridia will be discussed. Once the patient’s vision is assessed and goals are established with a thorough eye examination, numerous avenues can be taken to ensure the support of all the patient’s health care providers. Referrals can be made to appropriate professionals to ensure full understanding and management of the ocular condition. Visual acuity is the measurement used to determine vision levels. Normal vision is 20/20, which means that what a normal person sees at 20 feet, the patient sees at 20 feet. If their vision is 20/40, they would need to be at a distance of 20 feet to see what someone with normal vision can see at 40 feet. The decrease in visual acuity in those with aniridia usually ranges from under 20/60 to as low as approximately 20/400. This is due to the lack of development of the macular area, or fovea. The fovea is responsible for our clearest, most precise vision. Those with visual acuity of 20/200 or worse that is best corrected while wearing spectacles or contact lenses in the better-seeing eye are considered legally blind. While most people who suffer from aniridia are not legally blind, they are visual impaired. Visual impairment is defined as visual acuity of 20/70 in the better-seeing eye when optimally corrected with glasses or contact lenses. The designation of “visual impairment” also has a functionality factor. If a person has a reduction in the ability of the eye or the visual system to perform to a normal ability, he/she is considered visually impaired. Visual field is the measurement of peripheral vision. Those with aniridia may have decreased peripheral vision. This is not directly due to aniridia, but rather to glaucoma, which may develop due to structural changes in the eye. Glaucoma is explained in detail in the glaucoma chapter of this book.
