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.

Objective To analyze the clinical features of retinal detachment in macular spontaneous hemorrhage to improve the level of diagnosis and treatment of this disease. Methods The serial clinical data of 23 patients (23 eyes) with subretinal hemorrhage in macular region with the area over 4DDtimes;5DD who were diagnosed in our hospital from Sep, 1998 to Mar, 2003 were analyzed retrospectively. The patients included 12 males (12 eyes) and 11 females (11 eyes) with the average age of 64.1 (47-75). Fundus fluorescein angiography (FFA), indocyanine green angiography (ICGA) and B-scan examination were performed on the patients to analyze the pathogenic factors, and the visual acuity and manifestation of ocular fundus were observed during the 8-24 months followed-up period. Results The visual acuity decreased to less than 0.2 or light perception suddenly in all affected eyes. In 23 eyes, choroidal neovascularization (CNV) of age-related macular degeneration (AMD) was found in 7, polypoidal choroidal vasculopathy (PCV) was in 5, retinal macroaneurysm was in 2, and unknow pathogenic factor in 9. Among the 23 eyes, hemorrhage was absorbed and no cicatritial formation at the fovea in 3 eyes with the visual acuity of 0.4-0.8; scar and pigment proliferation in the hemorrhage area were seen in 12 eyes with the visual acuity of finger counting (FC) to 0.2; combined vitreous hemorrhage was found in 8 eyes, including massive scar in the macular area in 3 who had undergone vitrectomy with the visual acuity of FC/66cm to 0.2 and blindness in the other 5 eyes. Conclusion Spontaneous hemorrhagic retinal detachment always arises in old people whose symptoms were sudden decrease or loss of the visual acuity. The configuration of the hemorrhage is local and diffuse. The prognosis of the visual acuity of most of the patients is poor due to the serious tissue injury in macula area.

Objective To explore the clinicopathological features and misdiagnosed causes of choroidal hemangioma. Methods Seven misdiagnosed cases(7eyes) of choroidal hemangioma,which were enucleated,were analysed retrospectively. Results One of the 7 cases was misdiagnosed as absolute phase of the secondary glaucoma,and 6 of them as choroidal melanoma before the enucleation.The majority of cases in this series manifested themselves clinically and pathologically in progressive loss of visual acuity and a flat elevated tumor located at the posterior ocular fundus near the optic disc and associated with exudative retinal detachment.And also there were occasionally small focal or linear pigmentary deposites obser ved on the surface of the neoplasm. Conclusion A flat elevated discoid tumor in the posterior fundus with extensive exudative retinal detachment might be a clinicopathological feature of the choroidal hema ngioma.
