Insights
Topical tacrolimus 0.03% ointment effectively treated severe phlyctenular keratoconjunctivitis in two children. This treatment resolved corneal infiltrates and neovascularization without side effects.
Area of Science:
- Ophthalmology
- Immunology
Background:
- Phlyctenular keratoconjunctivitis is an inflammatory eye condition often requiring intensive treatment.
- Refractory cases may not respond to conventional therapies like corticosteroids and antibiotics.
Observation:
- Two pediatric patients with severe, refractory phlyctenular keratoconjunctivitis presented with corneal infiltrates, neovascularization, and thinning.
- Previous treatment with topical corticosteroids and oral erythromycin provided no relief.
Findings:
- Addition of topical tacrolimus 0.03% ointment to existing therapy led to rapid symptom and sign improvement within one week.
- Complete resolution of corneal pathology was observed after three weeks of treatment.
- Tacrolimus was successfully tapered, and no adverse effects were reported.
Implications:
- Topical tacrolimus 0.03% ointment shows promise as a safe and effective treatment for severe, refractory phlyctenular keratoconjunctivitis.
- This immunomodulatory agent may offer an alternative for patients unresponsive to standard care.
- Further studies are warranted to confirm efficacy and safety in a larger cohort.
Purpose:
To report 2 cases of refractory phlyctenular keratoconjunctivitis treated with topical tacrolimus 0.03% ointment (Protopic).
Methods:
Two white children, aged 5 years and 6 years, respectively, presented with refractory phlyctenular keratoconjunctivitis in 1 eye (left). Both were using corticosteroids and oral erythromycin at presentation with no relief. Examination revealed the presence of catarrhal corneal infiltrates and neovascularization associated with corneal thinning. Topical tacrolimus was added to topical steroids and oral erythromycin twice daily.
Results:
Topical tacrolimus 0.03% ointment was applied into the lower fornix twice a day. In both the patients, improvement in symptoms and signs started within a week of therapy. After 3 weeks of treatment, both patients showed complete resolution of corneal infiltrates and neovascularization. Tacrolimus was successfully tapered in both the patients. There were no side effects.
Conclusions:
Topical tacrolimus 0.03% ointment may be considered in treating severe refractory phlyctenular conjunctivitis.
