BACKGROUND The retina is an uncommon site for metastases, in particular from solid tumors. Some authors have reported a recent increase in the incidence of metastases in infrequent sites, such as brain or bone, probably due to the expanded treatment options and the resulting improved survival. Choroidal metastasis is the most common type of intraocular malignancy. The most common primary sites ...

Background and purpose: Retinal detachment is an ophthalmic problem in which subsequent complications could be avoided if diagnosed on time. This research aims at studying the prevalence of the causes of retinal detachment in the patients admitted to Tabriz Nikokari a hospital. Materials and methods: Ïn a descriptive study, 300 patients with retinal detachment admitted to Tabriz Nikokari H...

Retinal detachment surgery has been considered an inpatient hospital procedure requiring preoperative and postoperative hospitalization. In this pilot study, outpatient retinal detachment surgery was performed on sixteen patients and the results (100% success rate after an average follow-up of 8.3 months) were comparable or better than reported overall success rates for retinal detachment ...

Introduction: Degenerative retinal diseases are main cause of irreversible blindness. Stem cells therapy is a promising way in these diseases. Therefore, mesenchymal stem cells because of its safety can produce degenerated cells and can play important role in treatment. The aim of this study was to examine morphological changes in injured retinal pigment epithelium (RPE) and photoreceptor cells...

Circumscribed choroidal hemangioma is an uncommon, benign vascular tumor manifesting as an orange-red mass in the posterior pole of the eye. Serous retinal detachment accounts for decreased vision in most patients. Diagnosis of this tumor is challenging with many patients initially misdiagnosed with choroidal melanoma or metastasis. Several ancillary tests such as ultrasonography, fluorescein a...

Several signaling pathways and transcription factors control the cell fate in its in vitro development and differentiation. The orchestrated use of these factors results in cell specification. In coculture methods, many of these factors secrete from host cells but control the process. Today, transcription factors required for retinal progenitor cells are well known, but the generation of these ...

The choroid is the most common site for intraocular metastatic disease. Photodynamic therapy (PDT) can effectively destroy malignant tissue and induce anti-tumor activity. Recent publications support its use as an effective therapy for the treatment of choroidal metastases, especially in the subfoveal region, resulting in subsequent vision preservation or improvement. Here, we introduce a case ...
