Ocular Surface Squamous Neoplasia(OSSN)


What is OSSN?

Ocular Surface Squamous Neoplasia refers to an elevated, grey-white growth 

on the surface of the eye. This growth can be visually identified and may exhibit 

congestion, redness, ocular irritation, itching, and a foreign body sensation. 

If left untreated, OSSN poses a significant risk to vision and may even lead to total 

eye removal in extreme cases.

What are the causes and risk factors of OSSN?

1. Age and Gender: 

OSSN primarily affects the elderly population, typically occurring in the 6th to 7th decade of life. Males are more commonly affected than females.

2. Environmental Factors: 

Excessive exposure to ultraviolet (UV) radiation is a known risk factor. UV radiation from sunlight can contribute to the development of OSSN.

3. Lifestyle Habits: 

Heavy cigarette smoking has also been identified as a risk factor for OSSN, emphasizing the importance of lifestyle choices in eye health.

What are the symptoms of OSSN?

1. Elevated Growth: 

OSSN typically manifests as an elevated, grey-white growth on the eye’s surface, making it visually identifiable.

2. Conjunctival Congestion: 

The affected area may appear congested and red, indicating inflammation and potential irritation.

3. Ocular Irritation: 

Individuals with OSSN may experience discomfort, ocular irritation, itching, and a persistent foreign body sensation.

4. Vision Impairment: 

As the condition progresses, OSSN can lead to a gradual loss of vision, underscoring the importance of timely diagnosis and intervention.

What is the diagnosis and treatment of OSSN?

1. Medical Evaluation: 

If you experience symptoms indicative of OSSN, it is crucial to seek prompt medical evaluation. An eye care professional will conduct a thorough 

examination to confirm the diagnosis.

2. Biopsy: 

A biopsy may be performed to analyze the tissue and determine the nature of the growth, guiding the treatment plan.

3. Treatment Options: 

The treatment approach for OSSN may vary and can include surgical excision, cryotherapy (freezing), or topical chemotherapy. The choice of treatment 

depends on the size and extent of the lesion.

4. Follow-Up Care: Regular follow-up appointments are essential to monitor the progression of OSSN and adjust the treatment plan if necessary.

Ocular Surface Squamous Neoplasia demands vigilance, especially in the elderly male population. Timely diagnosis and appropriate treatment can 

prevent vision loss and more severe consequences. If you suspect OSSN or experience any related symptoms, consult with an eye care professional 

promptly toensure the best possible outcome for your eye health.
