Ocular Surface Squamous Neoplasia

Ocular Surface Squamous Neoplasia (OSSN) is a type of cancer that affects the surface of the eye, specifically the conjunctiva and cornea. It arises from the epithelial cells and can range from precancerous changes to invasive cancer. OSSN is often linked to exposure to ultraviolet light, chronic inflammation, or human papillomavirus (HPV). Symptoms may include redness, irritation, blurry vision, or visible growths on the eye. Early detection and treatment are important to prevent progression and ensure the best outcomes. Treatment may involve surgery, chemotherapy, or other therapies, depending on the severity of the condition.
