Answer

It seems as though Ali might be suffering from seasonal allergic conjunctivitis. The reason for this is that both eyes are affected, and he seems to be suffering from other allergy symptoms.

Allergic conjunctivitis is usually caused by sensitivity to tree and/or grass pollen, dust mites or animals and can be common for allergy sufferers. Ali shouldn’t require a referral to a GP unless his symptoms persist or worsen.

Although the symptoms of allergic conjunctivitis are very similar to viral conjunctivitis – including red, sore, itchy eyes – allergic conjunctivitis will always affect both eyes and may be accompanied by nasal congestion, sneezing, swelling around the eyes and light sensitivity. Unlike viral conjunctivitis it is not contagious.

There are a range of treatment options Vicky can recommend over-the-counter (OTC), including mast-cell stabiliser eye drops, antihistamine eye drops and antihistamine tablets. Mast-cell stabilisers help to block the release of inflammatory substances, such as histamine, and reduce symptoms like redness, swelling and itching.

Vicky should also advise that Ali avoids wearing contact lenses until 24 hours after using drops for the last time, prevents touching or rubbing his eyes or applying any eye makeup. Avoiding the cause of irritation may be difficult, especially if it’s pollen, however, wraparound sunglasses can be a good way to protect the eyes and are a more viable option than having to avoid leaving the house completely. Ali should also be aware that he should thoroughly wash his hands before touching his eyes, especially when using eye drops or contact lenses.
