AIM:To observe the clinical effect of different concentration of fluorometholone eye drops on severe mixed vernal keratoconjunctivitis in children.METHODS: A total of 50 cases(100 eyes)of children with severe mixed vernal keratoconjunctivitis treated in the outpatient department of our hospital from March to September, 2022 were selected and randomly divided into two groups. Group A consisted of 25 cases(50 eyes)who were treated with 0.1% fluorometholone eye drops combined with 0.05% cyclosporine eye drops(Ⅱ), while 25 patients(50 eyes)in group B were treated with 0.02% fluorometholone eye drops combined with 0.05% cyclosporine eye drops(Ⅱ). After 1mo of treatment, SPEED questionnaire score, corneal fluorescein staining(FL)score, tear break-up time(TBUT), Schirmer I test(SⅠt), R-scan, non-invasive tear meniscus height(NIKTMH), corneal optical density and other ocular parameters of the two groups were observed, and the occurrence of adverse reactions were recorded.RESULTS: After 1mo of treatment, there were significant differences in SPEED score, FL score and R-scan results between the two groups(all P<0.05), and no differences in TBUT, SⅠt and NIKTMH results(all P>0.05). However, there were statistical significance in corneal optical density in different corneal depth and diameter ranges(all P<0.05). After 1mo of treatment, there was no significant difference in intraocular pressure between the two groups(16.21±2.90mmHg vs. 16.05±2.75mmHg, P>0.05), and no obvious adverse reactions occurred during treatment.CONCLUSION: The 0.1% fluorometholone eye drops can effectively treat severe mixed vernal keratoconjunctivitis in children, and its effect is better than 0.02% fluorometholone eye drops.
