What is the diagnosis for a 10-year-old male with itchy eyes, severe photophobia, and cobblestone papillae?

The presence of itchy eyes, severe photophobia, and cobblestone papillae in a 10-year-old male suggests a diagnosis of vernal keratoconjunctivitis (VKC). VKC is a type of allergic conjunctivitis commonly seen in children and young adults, especially in warmer climates and during the spring season. The characteristic cobblestone papillae are typically found on the upper tarsal conjunctiva and indicate a chronic allergic response, which aligns with the symptoms of itchiness and photosensitivity.

The severe photophobia often associated with VKC can be attributed to the inflammation of the conjunctiva and cornea, leading to sensitivity to light. This condition is known for its recurrent episodes and may have triggers such as exposure to pollen or dust.

Conditions like iritis, bacterial conjunctivitis, and epidemic keratoconjunctivitis present with different symptom profiles that do not fully align with the symptoms of VKC. Iritis tends to cause pain and decreased vision along with photophobia, but it doesn't typically involve itching or cobblestone papillae. Bacterial conjunctivitis usually presents with purulent discharge and less itching compared to allergic conditions. Epidemic keratoconjunctivitis, caused by viral infection, can lead
