Prevalence and impact of ocular allergy in the population attending UK optometric practice

To determine the prevalence of ocular allergy in patients attending optometric practices in the UK West Midlands and the impact this has on patients' daily lives.

Patients attending 9 optometric practices in the West Midlands, UK, were surveyed about the occurrence of ocular allergy, the severity of the symptoms and their treatment. Patients self-reporting ocular allergy were invited to complete a more detailed questionnaire.

Of the 1904 consecutive patients assessed (mean age 47.7±23.2 years, 55% female), 13% reported an allergy, 8% an ocular allergy, rated as at least mild in 85% of cases. Medication was used by 77% of patients reporting ocular symptomology. Patients with ocular allergy (n=126) completed the detailed questionnaire. Seasonal symptoms occurred for 3.4±1.9 months of the year with a peak in June to July. The most common 'hayfever' type symptoms were itchy eyes and a runny nose, and ocular symptoms were itchiness and a desire to rub the eyes. Most had gained medication over the counter (73%) with advice from GPs (53%), pharmacists (41%) or a friend or relative (18%). Only 11% consulted an optometrist. Medication was mainly in the form of antihistamine tablets (71%), eye drops (40%) and nasal spray (40%). Those interested in a specialist ocular allergy service (83%) were willing to pay £15.50 on average.

Ocular allergy is relatively common, but treatment is often self-managed, does not appear to totally overcome the discomfort and rarely involves a detailed eye examination.
