background: autologous skin graft is frequently used in the field of plastic, and reconstructive surgery. the engraftment is dependent upon revascularization and angiogenesis, which can be regulated by different factors. in addition to its hematopoietic effects, erythropoietin is shown to positively affect the wound healing process. objectives: we studied effects of human erythropoietin on reva...

Retinal tumour is one of the less frequent manifestations of von Recklinghausen's neuro-fibromatosis, and the histology of the retinal lesions is rarely reported. It is the purpose of this paper to present a case of extensive glial hamartoma of the retina associated with glaucoma and advanced proliferative changes of the uvea in an adolescent girl with generalized neurofibromatosis. The case is...

PURPOSE To show the utility of optical coherence tomography (OCT) for studying the anterior segment and to explain its potential advantages as compared to ultrasonic biomicroscopy (UBM). MATERIALS AND METHODS We have described the findings in 5 patients with different pathologies of the anterior segment, all of whom were studied with UBM and OCT-3 adjusted for the anterior segment. There were...

tral retinal vein occlusion, and retinal detachment. Although data in the literature regarding the presence of VEGF in uveal melanoma are conflicting, our report shows the presence of VEGF in an iris melanoma. Kvanta and colleagues demonstrated the presence of VEGF protein in retinoblastoma but not in posterior uveal melanomas. Similarly, in a study of VEGF expression in central retinal vein oc...

Biometric recognition is an automatic identification method which is based on unique features or characteristics possessed by human beings and Iris recognition has proved itself as one of the most reliable biometric methods available owing to the accuracy provided by its unique epigenetic patterns. The main steps in any iris recognition system are image acquisition, iris segmentation, iris norm...

The evolution and characteristics of diabetic rubeosis were studied in 33 eyes, and the following vascular abnormalities were found: (1) Dilated leaking capillaries around the pupil; (2) irregular or slow filling of the radial arteries; (3) superficial arborising newly formed vessels, usually starting in the chamber angle; and (4) dilatation and leakage of the radial vessels either before or af...

PURPOSE To determine the most appropriate time for laser irradiation to produce selective occlusion of new corneal vessels by photodynamic therapy (PDT) with a new photosensitizer, ATX-S10(Na). METHODS The time course of the plasma levels of ATX-S10(Na) and the degree of dye accumulation in the corneal neovascularization after intravenous administration was determined in rabbit eyes. Plasma c...
