Best that this is answered by an opthalmologist
Hi, welcome to the forum, your symptoms are suggestive of allergic conjunctivitis which can form a granulomatous lesion over conjunctiva. Usually seen due to airborne allergens contacting the eye. If you have a history of hay fever, allergic rhinitis or bronchial asthma then the probability of allergic conjunctivitis is strong. But usually symptoms are seen in both the eyes.
The steps for management is
- Firstly you need to undergo examination of the eye which includes External examination, Slit-lamp examination of Eyelids, Conjunctiva, Tear film and Cornea by an Ophthalmologist.
- Frequent use of artificial tears.
- Allergen exposure avoidance by limiting outdoor exposure, use of air conditioning, and keeping car and home windows closed during the peak seasons.
- Short-term administration of over-the-counter topical antihistamine/vasoconstictor agents will help.
The other possibilities are viral conjunctivitis esp. due to herpes simplex type I, usually manifests as blisters and involve eye too. It is usually painful. Other causes are Noninfectious, nonallergic conjunctivitis; Chlamydial infections can cause Trachoma and Adult inclusion conjunctivitis.
I suggest you to consult ophthalmologist for further evaluation and appropriate treatment. Take care and regards.
