... Abstract Drug delivery into the posterior segment of the eye is complicated by the existence of the blood-ocular barrier. Strategies for delivering drugs to the posterior segment include systemic administration, modification of the barrier, and local drug delivery (including transcorneal...

... Abstract Posterior uveitis is a major cause of ocular morbidity worldwide. Systemic corticosteroids (CS) remain the primary method of treatment for noninfectious posterior uveitis; however, CS are associated with many side effects. Immunomodulatory therapy (IMT) is recommended when inflammatory...

... Abstract Posterior pharyngeal wall augmentation is a useful technique in selected patients with velopharyngeal insufficiency who have a small central velopharyngeal gap. Options for augmenting this region include using posterior pharyngeal wall flaps to create bulk and implanting various...

... Abstract Therapeutic radiation to the posterior segment of the eye is a common option for posterior segment tumors. Such tumors are often malignant, but sometimes, benign neoplasms are treated with ionizing radiation. Also, non-neoplastic intraocular lesions like wet age-related macular...

... Abstract Embryology of the posterior segment of the eye is significant in terms of understanding many pediatric retinal diseases, in particular coloboma formation and persistent fetal vasculature syndrome. Embryology of the eye has been described over several decades. Using some newer...

... an endoscopic posterior cricoid split with rib grafting after the age of 1. Abstract Bilateral vocal fold immobility(BVFI) can be divided into bilateral vocal fold paralysis and cricoarytenoid joint fixation, which can be accompanied with laryngeal stenosis. In children with BVFI, requiring...

... Abstract Infarctions in the territory of the posterior cerebral artery (PCA) occur in about 5-10% of all ischemic strokes. The PCA can be divided into ‘deep' (P1 and P2 segments) and ‘superficial' (P3 and P4) segments. Occlusion of paramedian perforating arteries arising from P1 causes rostral...

... Abstract Drug delivery into the posterior segment of the eye is complicated by the existence of the blood-ocular barrier. Strategies for delivering drugs to the posterior segment include systemic administration, modification of the barrier, and local drug delivery (including transcorneal...

... Abstract While the molecular mechanisms of anterior pituitary development are now better understood than in the past, both in animals and in humans, little is known about the mechanisms regulating posterior pituitary development. The posterior pituitary gland is formed by the evagination...

... Abstract Sight-threatening intraocular inflammation affecting the posterior segment of the eyemay be predominantly located in the peripheral retina and vitreous (intermediate uveitis) orpostequatorially where it manifests as inflammation of the retina, retinal vessels and/or opticnerve...
