Background: Retinoblastoma (RB) is the most common intraocular malignancy in childhood. The aim of this study was to investigate the epidemiological features and survival rates of patients with RB in southwestern Iran. Materials and Methods: This retrospective study was conducted on patients with RB referred to the only referral center of southwestern Iran from 2010 to 2018. Demographic charac...

BACKGROUND/AIMS Limbal allotransplantation is increasingly being used for ocular surface repair in patients with limbal stem cell dysfunction. However, it is uncertain whether donor cells survive long term on the ocular surface and whether patients maintain the early benefits of the procedure. The aims of this study were to investigate the long term outcome of clinical limbal allografts and to ...

BACKGROUND AND PURPOSE To report outcomes and toxicity after proton beam radiotherapy for non-peripapillary choroidal and ciliary body melanoma considered unsuitable for other eye-sparing therapies. MATERIALS AND METHODS An existing database of 77 patients with non-peripapillary tumors treated at TRIUMF, Canada, including patient, tumor, and treatment characteristics, was updated with ocular ...

Strabismus induces an abnormal pattern of alternating light and dark columns of cytochrome oxidase (CO) activity in macaque striate cortex. This pattern may arise because visual perception is suppressed in one eye to avoid diplopia. To test whether CO activity is reduced in the ocular dominance columns of the suppressed eye, we performed monocular enucleation to co-label the ocular dominance co...

The treatment of primary vitreoretinal lymphoma (PVRL) remains controversial regarding the use local, systemic, or combined treatments. aim this study was to analyze efficacy and toxicity intravenous high-dose methotrexate (IV HD-MTX) based systemic therapy in a uniformly treated population PVRL patients. From nationwide French database, we retrospectively selected 59 patients (median age: 70 y...

PURPOSE OF REVIEW The management of cancer metastatic to the orbit and ocular adnexa (eyelid and periocular structures) has changed in recent decades. The purpose of this article is to review the incidence, presentation, and clinical features of metastatic tumors of the orbit and ocular adnexa and discuss their multidisciplinary care. RECENT FINDINGS The improved survival of patients with com...

Genetic factors determining the pathogenesis and course of ocular toxoplasmosis are poorly understood. In this study, we explored the development of experimental ocular pathogenesis in genetically dissimilar mice infected with either the RH strain, the PLK strain, or the immunodominant surface antigen 1 (SAG1 [P30])-deficient mutant of the RH strain of Toxoplasma gondii. At 11 days postinfectio...

PURPOSE LINGO-1 is a functional member of the Nogo66 receptor (NgR1)/p75 and NgR1/TROY signaling complexes that prevent axonal regeneration through RhoA in the central nervous system. LINGO-1 also promotes cell death after neuronal injury and spinal cord injury. The authors sought to examine whether blocking LINGO-1 function with LINGO-1 antagonists promotes retinal ganglion cell (RGC) survival...

purpose: controversy has recently risen about the presence of compensatory ocular countertorsion (coct) after head tilt. this study was performed to define the functional range of this phenomenon. methods: cycloplegic autorefraction was performed on 80 eyes with regular astigmatism 2d. objective autorefraction was performed in normal position, right and left head tilt positions of 5º, 10º, 15º,...

PURPOSE An important phase in the development of an ocular herpes simplex virus type 1 (HSV-1) subunit vaccine is the identification of an efficient, safe, and adjuvant-free antigen delivery system capable of inducing and sustaining long-term memory T-cell protective immunity. This study was conducted to test the hypothesis that immunization with self-adjuvanting lipopeptide bearing HSV-1 glyco...
