A new treatment for photophobia in posttraumatic aniridia: a case report.
PURPOSE: Using staining pigments with which we had gained experience in dermatography (medical tattooing) treatments of leucoma corneae, a new approach was developed to create an artificial iris-like staining at the mid-stromal level of the cornea to treat photophobia in a patient with posttraumatic aniridia. METHODS: After a central 4-mm half-depth trephination, a lamellar dissection of the corneal stroma toward the limbus was performed. A combination of colored pigments was introduced into this midstromal space, until a light blue artificial iris (to match the contralateral eye) with adequate blocking of light was created. RESULTS: A stable artificial iris was created in the mid-stromal level of the cornea. CONCLUSION: Dermatography pigments are stable in the corneal stroma and are useful to treat photophobia in aniridia following trauma.
Dermatography as a modern treatment for coloring leucoma corneae.
Since antiquity many attempts were made and hence many methods were devised to minimize the disfiguration and stigmatization caused by leucoma corneae. Dermatography, a refined, modified tattooing technique, was used successfully in three cases of leucoma corneae. The materials and method are safe and simple. Over a 3-year follow-up period, no negative reactions were found. The cosmetic results were very satisfactory.
Tattooing in maxillo-facial surgery.
A patient is described who had a discoloration of the skin caused by too deep tattooing of the oral mucosa. To avoid this complication a safe tattoo technique is described.
