Arma is one among Shuklagataroga explained by Acharya Sushrutha and Acharya Vagbhata. It is defined as IYARTI GACCHATHI ITI ARMA. Which means gradually spreading of fleshy growth occurring in Shukla mandala. The Lakshanas of Arma can be correlated with signs and symptoms of Pterygium in modern ophthalmology. Pterygium is a wing shaped fold of conjunctiva encroaching upon cornea from either side within interpalpebral fissure. Pathologically Pterygium is an elastotic degeneration of subconjunctival tissue. In a population-based study from rural central India, prevalence of pterygium increased from 6.7±0.8% in the age group from 30–39 years to 25.3±2.1% in the age group of 70–79 years. The epidemiological studies around worldwide have shown that prevalence rates ranges from 0.3% to 37.46%^.

Pterygium is more common in people living in hot climate, and in those who work outdoors. Thus it is considered as a response to prolonged effect of environmental factors such as exposure to sunlight (UV rays), dry heat, high wind and abundance of dust. Asymptomatic nature of the disease and non-availability of medical treatment are the main hurdles in management. Meanwhile it fails to decrease the complication such as development of cyst, ongoing diplopia, Dry eye, scleral or corneal melting. it not only affects the outlook of the patient, but also affects refractive astigmatism which can have significant impact on vision in advanced stage due to the invasion of cornea.

In modern science surgical treatment is only satisfactory approach. Recurrence after surgical excision is common and recurred lesions grow more aggressively than primary lesions. Cost of Surgery is too expensive. Hence to overcome the lacuna in modern therapeutics the present clinical study has been taken up. Therefore an alternative treatment which is safe, devoid of complication, easy to administer and cost effective is need for hour.

In Classics different treatment modalities are explained for the management of Arma mainly Lekhana, Chedhana, Anjana. Arma is a type of Mamsavriddhi (muscle like growth) hence Acharyas have indicated as Chedana sadya and Lekhana sadya vyadhi. Marichanjanaand Darvadyanjana both are mentioned in Basavarajeeyam, Netraroghadhikara. Hence an attempt is made to compare the efficacy of Marichanjana and Darvadyanjana in management of ARMA

 NULL HYPOTHESIS

 H₀ - Marichanjana is not effective in management of Arma with special reference to   pterygium.

 ALTERNATE HYPOTHESIS

H₁ - Marichanjana Is more effective than Darvadyanjana i in management Arma with special reference to pterygium

H₂ - Marichanjana is less effective than Darvadyanjana in management of Arma with special reference to pterygium.
