Question

A patient with contact lens since 2 years presented with the below features.
What is the most probable cause.

• A. Giant Papillary conjunctivitis
• B. Trachoma
• C. Vernal Keratoconjunctivitis
• D. OSSN

Answer 1

The Correct Option is A

The patient described has been using contact lenses for two years and presents with specific ocular features. To determine the most probable cause of these symptoms, we need to consider common eye conditions associated with prolonged contact lens use. The options provided are:

• Giant Papillary Conjunctivitis (GPC)
• Trachoma
• Vernal Keratoconjunctivitis
• Ocular Surface Squamous Neoplasia (OSSN)

Let's evaluate these conditions:

1. Giant Papillary Conjunctivitis (GPC): This condition is commonly associated with contact lens wear, especially in individuals using soft lenses. It is characterized by the development of large papillae on the conjunctiva, caused by mechanical irritation from the lenses.
2. Trachoma: Although it is an infectious disease caused by Chlamydia trachomatis, it is not typically associated with contact lens use. It is more common in areas with poor sanitation.
3. Vernal Keratoconjunctivitis: This is a seasonal allergic condition, typically affecting children and young adults, with a history of allergies. It is less likely related to contact lens use.
4. Ocular Surface Squamous Neoplasia (OSSN): This includes a spectrum of eye surface tumors; however, it is rare and not directly related to contact lens use.

Given the patient's history of contact lens use, the most likely cause of the symptoms is Giant Papillary Conjunctivitis (GPC). The characteristic feature of GPC, such as the development of large papillae, aligns with what is typically observed in contact lens wearers experiencing irritation.
