The aim of the present study was to determine the optimal dose and optimal target volume for marginal zone lymphoma of the ocular adnexa. Between January, 2008 and December, 2013, 40 patients with histologically proven primary marginal zone lymphoma of the ocular adnexa who underwent radiotherapy at the Tokyo Medical University were evaluated. The prescribed dose was 30 Gy in 15 fractions to th...

PURPOSE To assess the relative impact of elevated T-helper 2 (T(H)2)- and reduced T-Helper 1 (T(H)1)-dependent immune responses on ocular herpes simplex virus type 1 (HSV-1) infection. METHODS Signal transducer and activator of transcription protein 4 knockout mice (BALB/c-STAT4(-/-)) and wild-type BALB/c control mice were immunized with avirulent HSV-1 strain KOS or were mock-immunized. Thre...

PURPOSE To determine sonic hedgehog (Shh) expression and whether it exerts neuroprotective effects on retinal ganglion cells (RGCs) in a rat chronic ocular hypertension model. METHODS Intraocular pressure (IOP) elevation in adult rat was induced by episcleral vein cautery. Retinal expression of Shh protein and mRNA was determined by immunohistochemistry, Western blot analysis, and real-time P...

BACKGROUND This study was conducted to determine the treatment outcome of incompletely removed, histopathologically documented ocular surface squamous neoplasia with mitomycin-C. METHODS Through an interventional case series, 17 eyes of 17 patients presented with incompletely removed ocular surface squamous neoplasia were treated according to a protocol using two to three alternate seven-day ...

BACKGROUND Primary oculocerebral large cell malignant non-Hodgkin's lymphoma, formerly called ocular reticulum cell sarcoma, runs a uniformly fatal course. Once the central nervous system (CNS) is involved, survival without treatment is very limited. Although treatment does not substantially improve the long term survival, it provides short term improvement in these patients. METHODS The char...

purpose: to report the clinical findings and compare the outcomes of different surgical techniques evolved over time in a large series of patients with delayed-onset mustard gas keratitis (mgk). methods: this interventional retrospective case series includes patients with complications of delayed mgk. medical and surgical interventions to address dry eye, limbal ischemia and limbal stem cell de...

Background: Tolmetin (Tol) is a pyrrole acetic acid derivative that acts as a highly effective topical anti-inflammatory agent. Topical administration of Tol is effective for the management of ocular inflammations.The aim of this study was to formulate and improve a topical ophthalmic delivery system of Tol. Materials and methods: In the present study, ocular inserts of Tol were prepared using ...

Background: Behcet syndrome is a recurrent inflammatory disorder that frequently involves the ocular system. The purpose of this study was to determine the frequency of ocular involvement in cases of Behcet's disease in Babol, north of Iran. Methods: From April 2003 to December 2009, 100 cases of behcet's disease who were admitted at the Department of Ophthalmology and Internal Medicine of Babo...

PURPOSE To examine the effect of immunosuppression with intramuscularly injected cyclosporine and topical corticosteroid on limbal allograft survival in a new model in the inbred rat. METHODS Orthotopic limbal tissue harvested from male Fischer 344 (isografts) or male Wistar-Firth donors (allografts) was sutured into superior and inferior lamellar excision sites in female recipient Fischer 34...
