Treatment of vernal keratoconjunctivitis a double-masked study

Area of Science:

• Ophthalmology
• Allergy and Immunology

Background:

• Vernal keratoconjunctivitis (VKC) is a severe allergic eye condition affecting children.
• Effective management of VKC is crucial to prevent vision-threatening complications.

Purpose of the Study:

• To compare the efficacy of fluorometholone 0.1% (FML), cromolyn sodium 2%, and artificial tears in treating severe pediatric VKC.
• To assess the safety and tolerability of these ophthalmic preparations.

Main Methods:

• A double-masked, randomized study involving 31 children (aged 5-14) with severe VKC.
• Objective assessment of disease activity using a standardized five-point scale under slit lamp examination.
• Statistical analysis using the chi-square test to compare treatment outcomes.

Main Results:

• Fluorometholone 0.1% (FML) demonstrated statistically significant efficacy in treating severe VKC compared to both cromolyn sodium and artificial tears (p=0.05 and p=0.005).
• Cromolyn sodium 2% showed no statistically significant difference in efficacy compared to artificial tears.
• All treatments were generally well-tolerated, though one patient developed allergic blepharitis with FML, and another developed posterior subcapsular cataract after long-term corticosteroid use.

Conclusions:

• Fluorometholone 0.1% is a highly effective treatment for severe vernal keratoconjunctivitis in children.
• Cromolyn sodium 2% and artificial tears showed comparable, less effective outcomes for severe VKC in this study.
• While effective, potential side effects of FML and long-term corticosteroid use warrant careful monitoring.
