Purpose: To compare corneal morphologic changes in vernal keratoconjunctivitis (VKC) patients before and after treatment with topical cyclosporin (CsA).Methods: 23 VKC patients and 40 healthy subjects as controls were considered. All patients were treated with 1%CsA during their active phase. The impact of treatment on quality of life was evaluated administering the QUICK questionnaire. Both eyes were evaluated using the in vivo confocal microscopy (IVCM) before treatment (T0), at the end of treatment in Autumn (T1) and at the recurrence of symptoms in the next season (T2).Results: All VKC patients improved their QUICK scores after CsA treatment. IVCM highlighted corneal microstructural changes at the level of epithelium, sub-basal nerve plexus and stroma in patients affected by VKC and allowed to follow their evolution after topical treatment with CsA.Conclusions: IVCM is a valuable tool to evaluate the dynamic corneal changes in VKC before and after treatment with CsA.
