A 12 years old boy presents with recurrent attacks of conjunctivitis for the last 2 years with intense itching and ropy discharge. The diagnosis is –
**Core Concept**
The patient's symptoms of recurrent conjunctivitis with intense itching and ropy discharge suggest a chronic allergic condition. This is likely related to an abnormal immune response to antigens in the environment.
**Why the Correct Answer is Right**
The patient's symptoms are consistent with vernal keratoconjunctivitis (VKC), a chronic allergic condition that occurs in children and young adults. VKC is characterized by intense itching, ropy discharge, and conjunctival inflammation. The condition is thought to be caused by an abnormal immune response to antigens such as pollen, dust, and other environmental allergens. The ropy discharge is a hallmark of VKC and is due to the presence of mucous and inflammatory cells in the tears.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not describe a condition that is associated with intense itching and ropy discharge. Conjunctivitis caused by bacteria or viruses typically presents with redness, swelling, and a watery discharge.
**Option B:** This option is incorrect because it does not accurately describe the symptoms of VKC. Spring catarrh is a milder form of allergic conjunctivitis that typically presents with a watery discharge and mild itching.
**Option C:** This option is incorrect because it does not accurately describe the symptoms of VKC. Giant papillary conjunctivitis (GPC) is a condition that occurs in response to foreign bodies in the eye, such as contact lenses, and typically presents with a watery discharge and mild itching.
**Clinical Pearl / High-Yield Fact**
VKC is a chronic condition that requires long-term management with medications such as corticosteroids and immunomodulators. It is essential to identify and avoid allergens that trigger the condition, such as pollen and dust.
**Correct Answer:** D. Vernal keratoconjunctivitis
