The aim of this study was to determine the prevalence and type of ophthalmic diseases among horse populations in the suburbian riding clubs of Tehran. Ophthalmologic examinations were performed in 901 horses and ocular lesions were diagnosed in 40 (4.4%) animals. In the 54 eyes of these horses that had ocular defects, 103 ocular abnormalities were detected. Of those horses affected, 65% showed ...

PURPOSE Ocular immune privilege promotes tumor growth by hindering the development of innate and adaptive immunity. A prior study showed that ocular tumors expressing the membrane-only form of Fas ligand (FasL) terminate immune privilege, induce vigorous inflammation, undergo rejection, and induce systemic protective immunity. In these previous experiments the tumor cells used were genetically ...

ObjectivesEye involvement is a main presentation of Behcet's disease. This study was performed to evaluate possible determinants affecting the occurrence eye involvement, especially role early systemic treatment with immunomodulatory drugs on incidence ocular involvement.MethodsThis retrospective cohort 1166 patients in Clinic Rheumatology Research Center. All were followed up for at least 10 y...

OBJECTIVE Report on the 7-year experience with bilateral ophthalmic artery chemosurgery (OAC-Tandem therapy) for bilateral retinoblastoma. DESIGN Retrospective, single institution study. SUBJECTS 120 eyes of 60 children with bilateral retinoblastoma treated since March 2008. METHODS Retrospective review of all children treated at Memorial Sloan Kettering with bilateral ophthalmic artery c...

Allografts are afforded a level of protection from rejection within immune-privileged tissues. Immune-privileged tissues involve mechanisms that suppress inflammation and promote immune tolerance. There are anatomical features, soluble factors, membrane-associated proteins, and alternative antigen-presenting cells (APC) that contribute to allograft survival in the immune-privileged tissue. This...

We describe a case of 52-year-old man who presented with an episode of tonic-clonic seizures. He had right ocular melanoma 23 years ago with subsequent enucleation which was the standard treatment at that time. CT scans of the brain and of the thorax-abdomen-pelvis revealed widespread metastatic lesions in the brain, lung and liver. Further investigations including bronchoscopy with cytopatholo...

Background and objective:Many biochemical features of sulfur mustard (SM) intoxication remained unknown. So far, the direct association between biochemical parameter changes and ocular problems in patients exposed to SM is not evaluated.The current study aimed at evaluating the associations between the ocular findings in patients with SM intoxication and the changes of...

the histopathologic diagnosis of orbital and ocular adnexal lymphoproliferative lesions is difficult, resulting controversy in classification, determining benignity or malignancy of them and treatment modality selection. we designed the following study to evaluate clinical, histopathologic and if necessary immunochemical features of them in decreasing indeterminate cases. the study includes 51 ...

BACKGROUND AND AIM: Ocular disorder like, diplopia, mydriasis, blurred vision, ptosis, exophthalmos, and blindness (permanent or temporary) are infrequent complications of an injection of local anesthetics in mouth.The main purpose of this study was to survey the dentist’s knowledge and attitude about ocular disorders due to intra-oral anesthetics injection.<br...
