Ocular surface squamous neoplasia (OSSN)

Surgical treatment

The traditional treatment of OSSN is surgery.
 

Indications for surgery

Some patients are best treated by surgical excision. This includes those with:

  • Large tumours
  • An uncertain diagnosis

 

Surgery for OSSN

Removal of OSSN is usually performed under local anaesthesia. Traditionally at the time of surgery the surrounding area was frozen or painted with alcohol to eradicate any residual tumour cells. Now the tumour is simply excised and followup treatment with Mitomycin C is arranged if the diagnosis is confirmed by a pathologist.
