Introduction:  Pterygium is defined as a degenerative and hyperplastic process, which occurrs in the palpebral aperture, medially and laterally, in which the bulbar conjunctiva encroaches onto the cornea. Prevalence rate of pterygium in the world is 2 to 29%. The available surgeries for pterygium excision include bare sclera excision, conjunctival and conjunctival limbal autograft and use of amniotic membrane. The aim of this study is to compare the results and complications in pterygium surgery by bare sclera technique and autologolus blood graft fixation technique.

Methodology: The study group consisted of 50 patients divided into Group A (25) and Group B (25) who underwent pterygium excision by bare sclera technique and autologous blood autograft fixation technique, respectively, after complete systemic and ophthalmic examination.

Observations: On Day1 Post-Op, Group A showed 4(16%) and Group B showed 5(20%) cases of subconjunctival hemorrhage; Group B showed 4(16%) with conjunctival graft loss and 1(4%) with conjunctival graft edema. At 1st week, Group B had 2(8%) cases of conjunctival graft hemorrhage, 1(4%) case each of graft necrosis and epithelial inclusion cyst formation; Group A showed a single case of scleritis. At 1^st month, Group A had 4(16%) and Group B showed 3(12%) cases of corneal astigmatism; Group A also showed 2(8%) with scleral thinning. Recurrence of pterygium was found in 2(8%) cases of Group B and 8(32%) in Group A.

Conclusion: The pterygium surgery with auto grafting from the conjunctiva has lower recurrence compared to bare sclera technique with complications that are comparable for both the pterygium surgeries.
