Ocular surface squamous neoplasia: Growth, diagnosis, and treatment.

Abstract

BackgroundOcular surface squamous neoplasia (OSSN) is the most common malignancy of the ocular surface, often presenting as a non-pigmented lesion with atypical squamous epithelialization. It is usually asymptomatic and can be confused with benign conditions such as pterygium or conjunctival cysts. If untreated, OSSN may progress to invasive squamous cell carcinoma, causing vision loss or metastasis. The gold standard for diagnosing OSSN is histopathological examination after tumor resection. However, there are still unresolved issues in the clinical management of treatment.Main textIn this review, we have discussed the clinical characteristics, diagnostic techniques, and treatment options for OSSN. OSSN occurs due to changes in the living environment and ocular surface state. It starts as a benign squamous epithelial tumor, which can progress to atypical intraepithelial neoplasia and eventually turn into invasive squamous cell carcinoma. The postoperative pathological histology also shows a corresponding degree of differentiation. Various diagnostic techniques, such as diagnostic imaging, cell biology, and molecular biology, are emerging as valuable tools for distinguishing OSSN. Although surgical resection is the primary treatment for OSSN, drug therapy can also be applied for better management of OSSN treatment.ConclusionAccurately diagnosing OSSN requires advanced examination techniques before and after operation. This is crucial for healthcare professionals to evaluate and treat the condition effectively. Based on our clinical expertise, administering drug treatment before or after surgical resection may serve as a comprehensive and effective management approach for OSSN. This research holds immense potential for the future of personalized and precise medical care.
