Aqueous flow was measured fluorophotometrically in New Zealand white rabbits after unilateral decentralization of the cervical ganglion or cervical ganglionectomy to determine the role of ocular adrenergic input in regulating the circadian rhythm of aqueous flow. Both surgical procedures decreased the rate of aqueous flow during the dark phase when flow is high. During the light phase when flow...

PURPOSE To study the neuroanatomic characteristics of patients with Duane's retraction syndrome with high-resolution magnetic resonance imaging. METHODS The study included 11 consecutive cases, including five patients with type I, one patient with type II, four patients with type III, and one patient with inverse Duane's retraction syndrome. The patients underwent magnetic resonance imaging o...

Neurolymphomatosis is a rare manifestation of non-Hodgkin lymphoma characterized by infiltration of peripheral nerves, nerve roots, plexus and cranial nerves by malignant lymphocytes. This report presents positron emission tomography/computed tomography (PET/CT)imaging with 2-deoxy-2-18F-fluoro-D-glucose (18F-FDG) in 3 cases of non-Hodgkin lymphoma with nerve infiltration, including one newly d...

there are extensive evidences that show axonal processes of the nervous system (peripheral and/or central) may be degenerated after nerve injuries. wallerian degeneration and chromatolysis are the most conspicuous phenomena that occur in response to injuries. in this research, the effects of post-operative time following sciatic nerve crush on the number of spinal motoneurons were investigated....

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 evaluate the ocular surface characteristics and corneal microstructure in patients with newly diagnosed Graves disease (GD) with no evidence of active thyroid eye disease (TED). METHODS Eighty eyes of 40 patients with newly diagnosed GD and 40 age-matched control subjects were recruited in this cross-sectional study. All participants underwent ocular surface tests in the order of t...

background: variations of the brachial plexus are common and a better awareness of the variations is of crucial importance to achieve successful results in its surgical procedures. the aim of the present study was to evaluate the anatomical variations of the brachial plexus in adult cadavers.   methods: bilateral upper limbs of 32 fresh cadavers (21 males and 11 females) consecutively referred ...
