Ossn (OCULAR SURFACE SQUAMOUS NEOPLASIA )
Ocular Surface Squamous Neoplasia is comprised of a vast array of conjunctival and corneal lesions which runs from dysplastic lesions and extends towards invasive squamous cell carcinoma.
~Exposure to ultraviolet (UV) radiation
~genetic disorders such as xeroderma pigmentosa have a greater propensity of developing OSSN
~Human Papilloma Virus (HPV)
Treatment for OSSN can be administered surgically or by non surgical means, or in some cases, a combination of both; depending on the individual patient. Medical non-surgical treatments come in form of eyedrops, topical Mitomycin-C, 5-fluorouracil and Interferon Alpha 2b.
The process of surgical excision entails the resection of the OSSN from the eye surface, leaving behind a healthy margin of tissue, and the lesion is sent out for pathology testing
