= A b s t rac t =Two Cases of ruptured cerebral aneurysms associated with polycystic kidney diseases (PKD) are presented. Case 1 is a 60-year-old woman diagnosed as PKD after rupture of an anterior communicating artery aneurysm. Eleven days after successful aneurysmal clipping, she died of sudden massive intra-abdominal bleeding from kidney rupture. Case 2 is a 60-year-old man diagnosed as aneu...

Ultrasound evaluation for hip joint effusion is made using an anterior approach parallel to the longitudinal axis of the femoral neck. At the junction of the femoral neck and head the normal capsular margin should follow this bony contour with evaluation looking to assess outward capsular displacement by fluid or other pathology. If fluid is seen its echotexture should be determined as purely h...

OBJECTIVE To show how an extending capsulorrhexis can be rescued by a midway tangential capsular flap in order to achieve an uneventful phacoemulsification. DESIGN Consecutive case series. PARTICIPANTS Twenty-two eyes of 22 patients with extending capsulorrhexis treated at the Farabi Eye Hospital, Tehran. METHODS First, a tangential capsular opening was created on the border of the presum...

anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. it is also known as x-linked megalocornea. it is accompanied by the early development of cataracts, zonular anomalies, and rarely vitreoretinal disorders. cataract surgery involves the risk of subluxation of the cataract because zonular weakness. in addition, in m...

The ultrastructure of the human lens capsule and zonular attachments was studied using scanning electron microscopy. The capsule was found to have two components; an organized mass of undulating, roughly parallel fibrils and a granular component. The undulation of the capsular surface and filament organization was much less evident near the anterior pole. The zonules were also found to be fibri...

BACKGROUND The authors evaluated the impact of morphological and hemodynamic factors on the rupture of matched-pairs of ruptured-unruptured intracranial aneurysms on one patient's ipsilateral anterior circulation with 3D reconstruction model and computational fluid dynamic method simulation. METHODS 20 patients with intracranial aneurysms pairs on the same-side of anterior circulation but wit...

BACKGROUND AND PURPOSE The anterior communicating artery (AcomA) is a predilect location of aneurysms which typically carry higher rupture risks than other locations in the anterior circulation. The purpose of this study was to characterize the different flow types present in AcomA aneurysms and to investigate possible associations with rupture. MATERIALS AND METHODS Patient-specific computat...

Late capsular block syndrome (CBS) is a postoperative complication of cataract surgery. It occurs in cases in which there is a 360° adhesion between the continuous curvilinear capsulorrhexis and the anterior surface of the optic of a posterior chamber (PC) intraocular lens (IOL). This adhesion creates the potential for the formation of a sequestered space between the IOL and the posterior lens ...
