A new treatment modality for the enlarged extraocular muscles.

ABSTRACT

PURPOSE: evaluation of the role of combined injection of triamcinolone acetonide with 5 Fluorouracil in treatment of the enlarged extraocular muscles secondary to chronic non-specific non-infectious inflammation. METHODS: injection of 0.1 ml of triamcinolone acetonide 40 mg/ml and 0.1 ml of 5 Fluorouracil 50 mg/ml in the enlarged extraocular muscles secondary to chronic non-specific non-infectious inflammation in 6 patients, after the confirmation of the histopathological diagnosis of these patients by revising their medical records. RESULTS: There was a significant improvement in the visual acuity, in addition to a significant improvement also in the clinical and the radiological features in the patients who were consented for the trial of the new injection protocol. However, there was failure of clinical and radiological improvement in one case presented with sever fibrosis. There was a significant absence of the side effects in all patients except for one patient that reported discomfort near the inner canthus. CONCLUSION: The new protocol of the treatment is a promising modality that can be used in the chronic non-infectious inflammation without extensive fibrosis.
