Introduction:

Conjunctival keloids are rare abnormal growths of scar tissue that develop on the eye's surface, specifically within the conjunctiva. Unlike typical keloids that commonly occur on the skin after injury or surgery, conjunctival keloids are exceptionally uncommon. In this comprehensive article, we explore the characteristics, causes, clinical features, diagnosis, and potential management of conjunctival keloids.

Understanding Conjunctival Keloids:

Keloids are abnormal growths of scar tissue that form at the site of a wound, injury, or surgical incision. Conjunctival keloids specifically arise from the conjunctiva, the thin, transparent tissue that covers the white part of the eye and lines the inner surface of the eyelids. Conjunctival keloids are extremely rare and can cause concern due to their atypical location.

Causes and Risk Factors:

The exact cause of conjunctival keloids is not well understood. However, they are believed to occur due to an exaggerated healing response to ocular trauma, surgery, or inflammation. Some potential risk factors for conjunctival keloids may include:

• Previous Ocular Surgery: Trauma or surgical interventions involving the conjunctiva can trigger the formation of keloids.
• Chronic Inflammation: Prolonged inflammation or recurrent eye irritation may contribute to the development of conjunctival keloids.

Clinical Features:

Conjunctival keloids present unique clinical features, which distinguish them from other conjunctival growths. The following characteristics may be observed:

• Elevated and Firm Mass: Conjunctival keloids appear as raised, firm masses on the eye's surface. They can vary in size and may be pink, reddish, or flesh-colored.
• Overlying Conjunctival Abnormalities: Conjunctival keloids may be associated with changes in the surrounding conjunctiva, such as thickening, redness, or inflammation.
• Limited Mobility: Due to their location and firm consistency, conjunctival keloids may restrict eye movement in the affected area.

Diagnosis and Management:

Diagnosing conjunctival keloids typically involves a comprehensive eye examination and evaluation of the patient's medical history. An ophthalmologist may perform the following to confirm the diagnosis:

• Slit-Lamp Examination: The ophthalmologist will use a specialized microscope with a bright light to closely examine the conjunctiva and identify the keloid.
• Biopsy (Rare Cases): In certain situations, a biopsy may be performed to analyze the tissue and rule out other potential conjunctival growths.

Treatment and Management:

The management of conjunctival keloids is challenging due to their rarity and potential complications associated with treatment. Currently, no standard treatment guidelines exist. The approach to management may include:

• Observation: In some cases, conjunctival keloids may be monitored if they are not causing significant symptoms or impairing vision.
• Surgical Excision: Surgical removal of conjunctival keloids is technically difficult due to the risk of recurrence and potential complications. It may be considered in cases of severe symptoms or impaired vision.
• Adjunctive Therapies: In some instances, adjuvant therapies such as corticosteroid injections, cryotherapy, or radiation therapy may be considered to reduce keloid recurrence.

Conclusion:

Conjunctival keloids are rare abnormal growths of scar tissue that form on the eye's surface. Due to their atypical location and potential complications, management requires careful consideration and individualized treatment approaches. Early detection and timely evaluation by an ophthalmologist are crucial for appropriate management and to ensure optimal eye health.
