Answer: A. Posterior Subcapsular Cataract
Explanation: Vernal keratoconjunctivitis (VKC) is a, chronic form of ocular allergy that can potentially cause severe visual complications.
Affecting mainly children and young adults, it is an IgE- and T cell-mediated disease, leading to a chronic inflammation in which eosinophil, lymphocyte and structural cell activation are involved.
Moderate to severe VKC needs repeated topical steroid treatment to downregulate conjunctival inflammation.
Persistent severe symptoms, thick mucous discharge with moderate to severe corneal involvement, numerous and inflamed limbal infiltrates and/or giant papillae, indicate a need for corticosteroids.
