Ocular Surface Squamous Neoplasia (OSSN) is a spectrum of pre-cancerous and cancerous lesions of the conjunctival epithelium (transparent coat covering the surface of the eye).
This condition can be diagnosed clinically and if promptly treated can achieve complete cure-as in this case. The before and after photo of the patient shows that the lesion is completely removed and looks like there’s no surgery at all. If not operated on time, the cancer will invade into the eye can cause vision loss and can even become fatal.
Below is the picture of the lesion at presentation and with lissamine green staining. The keratin deposits and lissamine green staining on the lesion with feeder vessels leading up the lesion is pathognomic of OSSN.
Below is the before after picture in static mode so that you can appreciate the difference.

Surgery:
A no touch technique is used to excise the lesion with 4mm margins, alcohol keratectomy to excise involved corneal epithelium-followed by double freeze-thaw cryotherapy of conjunctival edges. The ocular surface reconstruction is done using Conjunctivo-Limbal Auto-Graft (CLAG) and Amniotic Membrane Grafting (AMG) gives best outcomes without complications.
