Epibulbar lesions are formed particularly in the conjunctiva and cornea. These lesions are classified into two distinct types that include pigmented and non-pigmented epibulbar lesions. The pigmented epibulbar lesions are those lesions that have pigments while the non-pigmented lesions are those that are translucent or transparent due to the absence of the pigments.         


Epibulbar pigmented lesions include conjunctival epithelial melanosis, conjunctival freckle, primary acquired melanosis (PAM), conjunctival nevus, congenital ocular melanocytosis, melanoma and orbital melanoma.
Non-pigmented epibulbar lesions include papilloma epibulbar choristoma, pyogenic granuloma, conjunctival intraepithelial neoplasia (carcinoma in situ, dysplasia), conjunctival squamous cell carcinoma, conjunctival Kaposi sarcoma, conjunctival lymphoma, mucoepidermoid carcinoma, and infiltration from lid tumors.
These lesions can be benign, malignant and premalignant which have high prevalence among the Caucasian population. However, the reason of the prevalence of these lesions in a particular population is not known.
Further studies are recommended to provide an in-depth analysis of the effectiveness of different treatments that can be used for the treatment of the epibulbar and non-pigmented pigmented lesions.

In attached file we give an overview of epibulbar lesions.
