Аннотация
BACKGROUND: The course after severe eye burns is characterized by many complications which require a longlasting and intensive therapy. The success of treatment is menaced especially by superficial problems like persistent erosiones which occur also after keratoplasty.
PATIENT: As a cause of persistent erosions, pathological changes of Bowmans' membrane are discussed. Therefore, it was removed by PTK (phototherapeutic keratectomy) in our patient, in order to allow better adhesion of the epithelium to the deeper, less changed layers.
THERAPY AND OUTCOME: The patient suffered from a severe burn accident of his right eye with liquid cement. After proliferations were excised twice, we had to glue on a hard contact lens as an artificial epithelium due to a persistent erosion. Later, the development of a bacterial keratitis required keratoplasty. The epithelium remained intact for eleven months, but then an erosion arose and persisted for nine months. Therefore we performed a PTK and the epithelium closed subsequently within four days.
CONCLUSION: The treatment of persistent erosions has been very difficult so far, and often procedures like artificial epithelium or even keratoplasty have been necessary. The astonishing course of our patient indicates, that PTK is a promising and less invasive therapy in these cases.
