OBJECT Recently, extended transsphenoidal surgery (ETSS) has become an alternative to transcranial surgery (TCS) for suprasellar meningiomas, although the relative benefits of ETSS have yet to be established. To evaluate the effectiveness of ETSS, the authors analyzed surgical outcomes of TCS and ETSS. METHODS During a 12-year period, 28 patients with(More)
OBJECTIVES The authors devised an extended transsphenoidal approach involving a submucosal posterior ethmoidectomy that allows for adequate exposure of the cavernous sinus. To evaluate the adequacy of this approach for removal of adenomas invading the cavernous sinus, the authors retrospectively analyzed the surgical outcomes obtained in treated patients.(More)
To assess the results of perimetry recorded under dark- and light-adapted (DA and LA) conditions in patients with acute zonal occult outer retinopathy (AZOOR) and to compare the results of electroretinography (ERG) and spectral-domain optical coherence tomography (SD-OCT) in two groups of AZOOR patients. Twelve patients with AZOOR were studied. The(More)
BACKGROUND Wolfram syndrome (WFS) is a recessive neurologic and endocrinologic degenerative disorder, and is also known as DIDMOAD (Diabetes Insipidus, early-onset Diabetes Mellitus, progressive Optic Atrophy and Deafness) syndrome. Most affected individuals carry recessive mutations in the Wolfram syndrome 1 gene (WFS1). However, the phenotypic(More)
Surgical intervention consisting of lateral orbitotomy, the indication of which is extremely wide for orbital tumor surgery, has been applied in cases of large, retrobulbar cavernous hemangioma. However, no method exists involving displacement of the tumor from the crowded orbital contents, with the exception of tumor traction toward the outer side. The(More)
In current commercial ophthalmic ultrasound diagnostic systems, image display methods and sizes of probes vary. In clinical practice, B-mode scanning is performed to detect both static and dynamic information. The former is primarily used to obtain the positional relationship between lesions and structures in the eye and the orbit, and the latter to detect(More)
