Choroidal melanoma: a review and case report.

BACKGROUND

Choroidal melanoma is the most common primary intraocular malignancy in adults. The ongoing Collaborative Ocular Melanoma Study (COMS) was designed to provide specific answers for the management of medium and large choroidal melanomas. The present consensus among authorities is that small (< 3 mm thick) suspected choroidal melanomas can be conservatively managed with periodic observation for evidence of growth.

CASE REPORT: Dilated fundus examination of a 68-year-old man revealed a pigmented uveal lesion straddling the ora serrata inferiorly at 5:30 in the right eye. It measured 5 mm in diameter with transillumination and 2.89 mm in thickness with B-scan ultrasonography. Questioning a small choroidal melanoma the patient was referred to an ocular oncologist, who confirmed the lesion was suspicious for choroidal melanoma.

CONCLUSION

Although there are clinical signs that suggest lesion growth, true growth must be recorded with serial photographs, ultrasound, and transillumination. Active therapy should usually begin once lesion growth is documented.
