Purpose:
To report on the beneficial results of an intense regimen of 0.05% cyclosporine eye drops, eight times a day in patients with therapy resistant vernal shield ulcers.
Methods:
Case cohort of four eyes of three male children with vernal keratoconjunctivitis complicated by shield ulcers, who were treated with frequent cyclosporine 0.05% eye drops and observed for up to 5 years.
Results:
Quick resolution of the shield ulcers and complete re-epithelialization within 14-25 days was observed after adding intensive treatment with cyclosporine 0.05% to regular anti-inflammatory, histamine blocking, and surgical therapy. In one patient, additional scraping of the bottom of the ulcer was needed.
Conclusions:
In patients with vernal shield ulcers, frequent installation of low-concentration cyclosporine eye drops seems to have a promising therapeutical value.
