Melanoma Konjungtiva

Abstract

Conjunctival melanoma is a very rare tumor of the eye which can be fatal. We reported a 42-year-old female having had a black tumor in her right eye for 6 months before she was admitted to the hospital. This tumor was neither painful, itchy, nor bleeding. The tumor was derived from a nevus. Vision of the right eye was 6/15, corrected with C=100X1050 (6/9) and vision of the left eye was 6/6. The field of vision of the right eye was limited to the lateral part; color vision test was normal; Amsler grid test was normal; pupils were isocor; and Relative Afferent Papillary Defect (RAPD) was negative. Movements of the right eye ball were normal, except for the right temporal part due to the tumor. The anterior segment of the right eye was normal. A funduscopy examination of the right eye showed that the optic papilla, retina, and macula were within normal limits. Routine blood examination, liver function, kidney function, lipid profile, clotting time, and bleeding time were within normal limits. ECG was within normal limits, and a chest X-ray showed no metastase. Based on all examinations, this patient was diagnosed as having conjunctival melanoma, associated with simple hypermetropic astigmatisme, and presbyopia. Key words: melanoma, tumor.
