Choroidal neovascularization (CNV) is a common and severe complication in heterogeneous diseases affecting the posterior segment of the eye, the most frequent being represented by age-related macular degeneration. Although the term may suggest just a vascular pathological condition, CNV is more properly definable as an aberrant tissue invasion of endothelial and inflammatory cells, in which bot...

B-scan ultrasonography is now widely used in ophthalmology for investigation of orbital lesions and posterior segment lesions when direct visualisation is prevented by opacity in the ocular media. Most authors have concentrated on ultrasonic demonstration of posterior segment lesions, but the separation of diseases of anterior and posterior segments is largely artificial. The present study has ...

OBJECTIVE To describe the microsurgical anatomy, branches, and anatomic relationships of the posterior cerebral artery (PCA) represented in three-dimensional images. METHODS Seventy hemispheres of 35 brain specimens were studied. They were previously injected with red silicone and fixed in 10% formalin for at least 40 days. Four of the studied specimens were frozen at -10° to -15 °C for 14 da...

Innovative and new drug delivery systems (DDSs) have recently been developed to vehicle treatments drugs the ocular posterior segment retina. New formulations technological developments, such as nanotechnology, novel matrices, non-traditional treatment strategies, open perspectives in this field. The aim of mini-review is highlight promising strategies reported current literature based on innov...
