Primary intraocular lymphoma (PIOL) is a relatively rare form of Non-Hodgkin’s Lymphoma arising in the lymphoid tissues of the eye. It is highly correlated with primary CNS lymphoma (PCNSL) and it is estimated that up to 80% of patients presenting with PIOL will eventually manifest intracranial malignancy, which is the largest contributor to mortality. Most patients present with nonspecific vis...

We report a case of intraocular lymphoma in a 65-year-old man, 15 months after cardiac transplantation. On Magnetic Resonance (MR) images, the iris and the anterior chamber of the right eye were found to be involved with an enhancing soft-tissue lesion. To our knowledge, this is the first case of post-transplantation intraocular lymphoma evaluated with MR imaging.

Background: Fine-Needle Aspiration Cytology (FNAC) is used for diagnosis of intraocular, orbital and eyelid lesions. In this study we evaluated the outcome and the accuracy of using this technique in diagnosis of benign or malignant behavior of lesions. Methods: FNAC was performed on 26 specimens obtained from 25 patients with intraocular, orbital and eyelid tumors and the results were compared...

Malignant glaucoma, which is characterized by a shallow or flat anterior chamber with high intraocular pressure, can usually be resolved by pars plana vitrectomy with anterior hyaloidectomy. We describe two cases in which malignant glaucoma was refractory to conventional treatment and complete vitrectomy. Case one an 88-year-old woman with pseudoexfoliation glaucoma underwent trabeculotomy and ...
