Arma is one among Shuklagatha Roga which is characterized by gradually spreading fleshy growth occurring in the Shukla mandala. Based on the bheda, varna, and dosha involved, Arma is classified into 5 types i.e., Prastari Arma, Shukla Arma, Kshataja/Lohita Arma, Adhimamsa Arma, and Snayu Arma. The anatomical understanding of the Shukla mandala and the symptoms of Arma suggest a comparison to Pterygium. In contemporary, Pterygium is a wing-shaped fold of conjunctiva encroaching upon the cornea from either side within the interpalpebral fissure. The main treatment for pterygium is surgical removal, which has to be taken into consideration in case of reduced visual acuity due to visual axis involvement, induced astigmatism, or frequent inflammation and discomfort. The prevalence rate of pterygium in the total population of India was 10%.

The treatment principles explained in the classics for Arma, Chedana followed by Lekhana Anjana is considered to be more effective. In Chedana procedure the excessive growth in the Shukla mandala is excised. “Nayanasukha varti” a medicine mentioned in the management of Arma in Bhaishajyaratnavali, Contains the Drugs having Lekhana, Chakshushya, Vranaropaka, Rasayana and Tridoshahara Properties.

Pterygium surgery is concerned by postoperative recurrence whose rate can be 24% to 89% and its severity may vary according to the adopted approach and preoperative conditions because fibrovascular growth may occur also with greater extension than its primary presentation. To reduce the recurrence rate advanced techniques have been adopted such as Conjunctival Autografting, Mitomycin C application, and Amniotic membrane graft. Conjunctival limbal autograft (hereafter referred to as "conjunctival autograft") involves removing limbal tissue and adjacent conjunctiva in one piece from another part of the person’s eye and using the tissue to cover the area from which the pterygium was excised. Recurrence of pterygium at three months after surgery ranged up to 16.7% in the conjunctival autograft. The postoperative complications observed included conjunctival encroachment over the graft, small graft, graft dislodging, thick graft, improper position, graft edema, ocular surface exposure, progressive horizontal conjunctivalization, and pyogenic granuloma.

Hence, to overcome the above complications, cost efficiency and effectiveness this study is undertaken to evaluate the effect of Nayanasukha varti Anjana in the prevention of the recurrence of Arma following the arma chedana karma. In this study the control group is conjunctival autografting following Arma Chedana in the prevention of recurrence of Arma.
