ABSTRACT
PURPOSE:
The aim of this study was to evaluate the role of cutaneous application of 0.1% tacrolimus eye ointment over the skin of the upper eyelid in chronic vernal keratoconjunctivitis (VKC).METHODS:
A prospective, longitudinal, noncomparative, open-label clinical study of moderate-to-severe grade steroid-dependent VKC was performed. Study participants were initiated on adjunct therapy of cutaneous application of 0.1% tacrolimus ointment twice daily on the upper eyelid skin. Ocular surface evaluation parameters, meibomian gland imaging, intraocular pressure, visual acuity, and clinical disease severity scoring were performed to assess clinical response at baseline and month 3 of therapy. Tear levels of tacrolimus were measured at month 3 using high-performance liquid chromatography tandem mass spectrometry and correlated with the clinical score.RESULTS:
Palpebral form of VKC was observed in 85% of the cases, with positive family history in 5%, atopy in 7.5%, and keratoconus in 11.25%. Clinical assessment revealed improvement in 97.5% patients with discontinuation of concomitant topical steroids in 64% of patients. There were no changes in visual acuity, intraocular pressure, or ocular surface evaluation after therapy. Tacrolimus was detected in the tears of all our study patients after cutaneous application over the upper eyelid skin, proving its bioavailability with mean tear tacrolimus levels of 6.55 ± 21.43 ng/mL. Correlation analysis revealed a moderate negative correlation between the clinical score and tacrolimus concentration (Spearman correlation coefficient -0.34, P = 0.002).CONCLUSIONS:
Cutaneous tacrolimus 0.1% ointment over the upper eyelid skin is an efficacious alternative method of application in treatment of VKC, with no resultant ocular irritation.
