Ocular Tumors In Iran: A 10-Year Histopathological Study On 384 Cases Of Enucleation

  Background and Objective: The frequency and pattern of eye neoplasms differ in various geographic areas. Our aim was to determine the distribution of patient age, gender, ocular tumor origin, location and histological type in our region. Materials and Methods: In this cross-sectional study, all of the 384 eye globe enucleation cases carried out during a 10-year period in Farabi Medical Cent...

Ocular and Periocular Tumors in Cats

Proton irradiation of simulated ocular tumors.

Silicone sponges were sutured to the sclera of owl monkeys to create an indentation which would simulate a tumor of the posterior segment of the eye. A tantalum clip inserted in the silicone sponge served as a marker for radiographic localization of the simulated tumors. The acute lesions obtained on the retina and choroid after moderately high doses of proton irradiation suggest that this meth...

Vascular basophilia in ocular and orbital tumors.

The occurrence of vascular basophilia in ocular tumors has been a selective histologic feature of retinoblastomas. We recently observed a metastatic oat-cell carcinoma to the choroid which also demonstrated such a vascular hematoxyphilia. Histologic review of a variety of ocular and orbital metastatic carcinomas failed to yield a similar basophilic pattern. Examination of 100 consecutive retino...

Dosimetric investigation of beta-emitting ophthalmic plaques for treatment of ocular tumors

Understanding the dose distribution of beta-emitting eye plaques respect to the location of tumor is of importance. In this study, the geometry of CCB, COB and CIB plaques (BEBIG manufacturer) for specific eye tumors were simulated and the effects of different coated radionuclides and plaque materials were investigated, by Geant4 simulation toolkit. For validation, a dosimetric investigation wa...
