Abstract
ObJective To determine characteristic of adult intraocular tumor on ultrasonography,computer tomography and magnetic resonance imaging and to analyze the difference of surgical.Methods A total of 136 patients (during the period from 2000 to 2010) suffering from intraocular tumor were retrospectively analyzed.Clinical manifestations,medical imagelogical features and operation methods were measured.All data were collected with Microsoft Access and analyzed by SPSS software.Results Among 136 cases uveal melanoma accounted for 101 cases,choroidal hemangioma 11 cases,uveal metastasis 16 cases,adult RB 3 cases and the others 5 cases.One hundreds and twenty five eyes were examined with ultrasonography,25 eyes with CT,58 eyes with MRI and 18 eyes with FFA.Tumors of 117 eyes were extirpated.US,CT and MRI had distinguished differences in diagnosis of uveal melanoma,and MRI had the highest detective rate.If combined with US and FFA,misdiagnosis rate may be significantly decreased.FFA had the highest detective rate in diagnosis of hemangioma.In order to acquire higher diagnosis rate,US and MRI should be considered.Metastasis three methods had a low diagnosis rate; in order to acquire higher diagnosis rate,pathological and clinical examinations should be considered.Conclusions Ultrasonography as the most convenient method in diagnosis intraocular tumor is considered as regular tool.If melanoma is suspected,MRI should be highly considered.On MRI,the typical choroidal melanoma appeared high signal intensity in T1WI and low signal intensity in T2WI.MRI has the advantage on differentially diagnosis than CT.FFA should be further considered when hemangioma is suspected.The FFA picture of hemangioma is particular value of diagnosis.MRI has the superior sensitivity in diagnosis and differentially diagnosing choroidal hemangioma than CT.Further investigation shows that there is a distinguish difference at different examining ways. Key words: Intraocular tumor; Medical imageology
