**Question:** Treatment of vernal keratoconjunctivitis includes all except-

A. Corticosteroids
B. Antibiotics
C. Cyclosporine
D. Anti-histamines

**Core Concept:** Vernal keratoconjunctivitis (VKC) is a type of allergic eye disease affecting children and young adults. It is characterized by chronic, recurrent, and bilateral ocular inflammation, with symptoms like redness, itching, tearing, and foreign body sensation. Treatment options aim to manage symptoms, reduce inflammation, and prevent complications.

**Why the Correct Answer is Right:**
Corticosteroids are generally not used as a first-line treatment for VKC due to their potential side effects like cataract formation, glaucoma, and increased risk of infections. Antibiotics are incorrect because VKC is an allergic, not infectious, condition. Cyclosporine, an immunosuppressive agent, may be used in cases where topical corticosteroids are ineffective or not tolerated, but it is not universally applicable.

**Why Each Wrong Option is Incorrect:**
Anti-histamines are used to alleviate allergy symptoms but are not effective in treating the underlying inflammation in VKC. They are not indicated in VKC treatment due to their limited efficacy and potential side effects.

**Clinical Pearl:** In cases of VKC, a multimodal approach involving topical corticosteroids, cyclosporine, and anti-inflammatory agents like topical mast cell stabilizers or leukotriene inhibitors is often used to manage symptoms and inflammation effectively.

**Correct Answer:** D. Anti-histamines
