Background
• Colchicine is a systemic anti-inflammatory drug
used for the long term treatment of Familial
Mediterranean Fever (FMF), Behcet’s disease,
Rheumatoid Arthritis, Gout and other diseases.
• Colchicine is known to prevent activation of
neutrophils and inhibit mitotic spindle formation.
It modulates chemokines, prostanoids
production and inhibits endothelial cell adhesion
molecules.1,2
Background
• Only recently the FDA approved colchicine
for the systemic treatment of FMF and
gout.
Background
• Delay in corneal wound healing in patients
treated with colchicine was previously
reported by Biedner et. al. who described
two cases of healing suppression in
corneal dellen after strabismus surgery.3
Methods & Patients
• We present a series of four patients, all
under systemic colchicine who presented
with corneal ulcers unresponsive to
treatment with topical antibiotics.
• Cessation of colchicine treatment resulted
in resolution of the corneal ulcer in all
cases.

Discussion
• We described four similar cases of patients on
colchicine Rx, unresponsive to conventional
antibiotic treatment.
• Colchicine may adversely affect wound healing
through its inhibitory effect on tubulin dependent
cell functions and through collagenase
activation. In some animal models and in vitro
studies, colchicine was shown to inhibit
epithelium and fibroblast mitosis, fibroblast
migration, endothelial cell migration and
collagen deposition. 4,5
Discussion
• Colchicine was demonstrated to be
excreted in the tear fluid in patients on
systemic Rx.6 This may provide a possible
route by which the drug may affect and
inhibit healing of corneal ulcers.
Discussion
• We cannot establish a definite cause-effect
relationship between colchicine and these
corneal complications. However, in light of
previous reports, the experimental data and the
fact that all of our patients were unresponsive to
conventional therapy while showing a dramatic
resolution once colchicine was withdrawn,
makes it reasonable to assume that the drug
interfered with corneal healing
Discussion
• We suggest that in patients with corneal
ulcers refractory to conventional treatment
who are being treated with colchicine,
cessation of colchicine treatment should
be considered whenever possible.
