Abstract
Six posterior uveal melanomas were karyotyped after shortβterm culture. One had a normal chromosome complement; the remaining five had limited chromosome changes. Involvement of chromosomes 1 and 6 was noted in two and four cases, respectively, and three ciliary body tumours demonstrated both monosomy 3 and i(8q).
