Laser perimetry: diagnostic application in six cases of pituitary Chromophobe Adenoma.
Acta ophthalmologica, 2009Co-Authors: F. Bartoli, L. LiuzziAbstract:An apparatus consisting of a Goldmann perimeter fitted with a laser generator is described. Sharper definition and earlier detection of defects with this technique in six cases of Chromophobe Adenoma are reported.

Image and pathological study of the Chromophobe Adenoma
Journal of Modern Oncology, 2008Co-Authors: Li Jing-yiAbstract:Objective:To discuss the pathological basis to image on CT and MRI of the Chromophobe Adenoma.Methods:To review CT and MRI images and pathology results obtained from 26 Chromophobe Adenoma patients,especially analyze cavernous sinus invasion,base of skull invasion,sphenoidal sinus invasion,internal carotid artery adhesion invasion.Results:Twenty two correct diagnosis before operation,including all cavernous sinus invasion and internal carotid artery adhesion invasion cases,false positive rates were 27.3 percent and 36.4 percent.CT and MRI images can display hemorrhage,putrescence,denaturalization and base of skull invasion.But had 5.5 percent of false positive rate.During the operations,17 cases were normal bloody supplied;and 3cases had abundance supplication of blood,without any relationships to the images.3 cases'pathology showed nuclear atypia and caryocinesia.Conclusion:CT and MRI images can more definitely display nidi of hemorrhage,putrescence,denaturalization and base of skull invasion;further more,images can sensitively display nidi of cavernous sinus invasion and internal carotid artery adhesion invasion,with some false positive cases.But the images can not offer the correct estimation of the bloody supply,and can not present Adenomas' ecology.

atrophy of optic nerve fibres in compression of the chiasm prognostic implications
Acta Ophthalmologica, 2009Co-Authors: Mats Lundstrom, Lars FrisenAbstract:A relationship between the degree of atrophy of retinal nerve fibres and visual field defect has been described in postoperative steady-state patients (LundstrOm & FrisEn 1976). The same factors were studied prior to surgery in six patients with compression of the chiasm due to Chromophobe Adenoma. In five eyes the field defect was excessive in relation to the degree of atrophy. After surgery the visual field defects improved to a level corresponding to the degree of atrophy in these eyes. In the remaining seven eyes there was a close correspondence between the atrophy and the visual field defect already before surgery. The visual field defects remained unchanged in these eyes. Provided that atrophy does not increase after surgery, simultaneous preoperative evaluation of retinal nerve fibre atrophy and visual field defect allows an accurate prediction of prognosis for improvement.
