The therapeutic effect of IPL on children with refractory seasonal allergic conjunctivitis

To observe the effectiveness of intense pulsed light(IPL) treatment as an adjuvant treatment of refractory seasonal allergic conjunctivitis in children. A total of 31 patients with refractory seasonal allergic conjunctivitis who did not respond well to anti-allergic drug treatment were randomly selected to receive drug therapy combined with IPL treatment (17 patients) and drug treatment alone (14 patients) for 1 week, and the ocular surface symptom questionnaire and ocular surface sign score were performed before and after treatment, respectively. After treatment, the IPL group had significantly lower scores in eye rubbing, blinking, eye itching, discharge, tearing, and total scores than before treatment (P < 0.05), while there was no significant difference in foreign body sense scores before and after treatment (P > 0.05). There were no significant differences in eye rubbing, blinking, eye itching, discharge, foreign body sensation, tearing, and total score between the control group after treatment (P > 0.05). After treatment, the scores of ocular signs in the IPL group and the control group were lower than those before treatment, and the difference was statistically significant (P < 0.01). IPL therapy is effective in improving ocular surface symptoms in children with refractory seasonal allergic conjunctivitis, especially in suppressing eye itching, with good results.
