Objective To observe the classification,clinical and pathological features of ciliary body tumors. Methods The clinical and pathological data of 11 cases of primary ciliary body tumors were analysed retrospectively. Results By pathological examination,the tumors of these cases were devided into malignant melanoma (2 cases), benign melanocytoma (3 cases),leiomyoma (2 cases), and angio- leiomyoma, neurilemoma, non-special granuloma and medulloepithelioma (1 case respectively). Both of the benign and malignant tumors of ciliary body tended to grow and enlarge progressively. The cardinal clinical manifestations of this series of 11 cases were as follows: elevation of intraocular pressure in 7, local scleral vascular dilatation in 5, secondary exudative retinal detachment in 5,and the signs of anterior uveitis in the early stage of tumor growth in 4. Conclusion The histopathological types of cilliary tumors are manifold,and the tumors are prone to enlarge progressively in developement either in benign or malignant ones, so that the rates of clinical misdiagnosis are relatively high.
