we present a very rare case of partially unroofed coronary sinus without persistent left superior vena cava in a 74 years old female with a history of hypertension, severe myxomatous bileaflet mitral valve prolapse with severe eccentric mitral regurgitation which was diagnosed during cardiac surgery.

this case study reports a rare variation of the superior laryngeal artery (sla), which is the principal arterial supply of the larynx. the knowledge of the arterial variations is essential for the surgeons to prevent blood loss and postoperative complications. during routine dissection of an adult male cadaver, a rare arterial variation in the sla was seen. in this case, the sla passed through ...

purpose : to report a new familial presentation of hypoplasia and absence of superior rectus in the form of unilateral monocular elevation deficiency case report : a 7-year-old boy was referred to our center (poostchi eye clinic) with a chief complaint of ocular misalignment in his right eye since birth. one of his siblings was a known case of unilateral monocular elevation deficiency and was o...

purpose: to compare the efficacy and safety of ahmed glaucoma valve (agv) implantation in the superior versus inferior quadrants. methods: this prospective parallel cohort study was performed on 106 eyes of 106 patients with refractory glaucoma. main outcome measures included intraocular pressure (iop) and rate of complications. other outcome measures included best-corrected visual acuity (bcva...

Background: In 1991, Wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. Originally, this procedure has been performed with silicone band expander. The aim of this study was to report the results of treatment of a series of patients with A-pattern strabismus associated with overacting superior oblique muscle using the fascia lata...

Visceral artery aneurysms are rarely reported. They can occur in the context of a variety of underlying diseases. These aneurysms may coexist with non-visceral arterial aneurysms.Here we describe an 80-year-old man with concomitant superior mesenteric, celiac, renal, and aorto-bi-iliac aneurysms. The patient was a hypertensive and hyperlipidemic old man with history of transient ischemic attack...

Dynamic visual acuity (DVA) is defined as the ability to discriminate the fine parts of a moving object. DVA is generally better in athletes than in non-athletes, and the better DVA of athletes has been attributed to a better ability to track moving objects. In the present study, we hypothesized that the better DVA of athletes is partly derived from better perception of moving images on the ret...

this article presents a new technique for weakening the superior oblique muscle by lengthening it's tendon. lengthening is accomplished by a nasal superior oblique tenotomy, and by inserting a segment of silicone band 240 between the cut ends of the tendon. this technique is useful for the treatment of brown syndrome and cases with superior oblique overaction.

conclusions in addition to an appropriate clinical history, ct findings indicating decreased aortomesenteric angle and a shortened aortomesenteric distance can suggest the diagnosis for both the superior mesenteric artery syndrome and accompanying nutcracker syndrome. case presentation in this report, a patient is described presenting with epigastric pain and weight loss due to superior mesente...
