Introduction:
Iris melanoma, even when a malignant tumor, has a slow progressive course. Surgical treatment is easy because of localization of the tumor but can be accompanied by a range of complications, from photophobia to cosmetic problems.
Materials And Methods:
We reviewed the records of 11 patients with iris melanoma treated by surgical excision with posterior limbus incision. Conventional iridectomy was performed in nine cases and iridocyclectomy in two cases.
Results:
There were seven females and four males ranging in age from 27 to 76 years. Histologically, 10 tumors were composed of B spindle cells and one was mixed. For all patients, followed up for 1-5 years, final visual acuity was more than 6/10. One patient complained of photophobia and cataract developed in one 76-year-old woman at the end of follow-up.
Conclusion:
Because of the good prognosis of iris melanoma, conservative treatment can be given in most of cases (without local complications). Surgical resection confirms diagnosis after histopathological examination, with good final functional result thanks to scleral tunnel incision, which induces less astigmatism than corneal incisions. In the future, these findings will have to be confirmed by a corneal topography study before and after surgery.
