Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be asked about their indirect symptoms of AC (squinting, blinking, frontal headaches or eyelid dermatitis) to assess whether they suffer. Then total Ocular Symptom Score (TOSS) (tearing, itching and eye redness) will be assessed.
Then, one drop of olopatadine hydrochloride to each eye, ONCE ONLY.
Then 5 minutes will pass before assessing TOSS again.

Allocation to intervention
Non-randomised trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Patients attending an allergist's outpatients clinic are asked if they would like to participate in this study. if they consent, then they are assessed for symptoms and signs of allergic conjunctivitis. If they do not have any history or symptoms, then they are administered olopatadine hydrochloride to determine if they improved total ocular symptoms scores in patients without allergic conjunctivitis.

Summary
Brief summary
Aim:
To determine the most effective way of detecting the incidence of allergic conjunctivitis (AC).
Method:
The first step includes asking patients in an allergy specialist's outpatient clinic about their Total
Ocular Symptom Score (tearing, itching and eye redness), then asking them about indirect
symptoms of AC (squinting, blinking, frontal headaches or eyelid dermatitis), and finally using
an olopatadine challenge to determine if any chronic, undetected symptoms of AC are relieved
and thus suffered.
A control group will be used to determine if the lubricating effects of the olopatadine eye drops
is acting as the relieving factor in the intervention group.
