To compare the effect of centrally aligned image acquisitions with that of roughly centered image acquisitions on the reproducibility of topographic parameters obtained with the Heidelberg Retina Tomograph. three optic nerve head images were acquired sequentially by the rough centration of live image on the monitor, after then another three images sequentially by the central alignment in five healthy eyes of five subjects. For the centrally aligned image acquisitions, the contour of the frozen live optic nerve head image of each eye was copied into the transparent film. The images were acquired when the margin of live image fitted the contour line on the film. The reliability coefficients of the parameters ranged from 59.4% to 98.2% by the rough centration and 89.7% to 98.7% by the the central alignment. The results indicate that centrally aligned image acquisition provide highly reproducible topographic data of optic nerve head.

Traumatic optic neuropathy (TON) refers to optic nerve injury resulting from direct and indirect head and facial trauma. The pathogenesis of indirect TON has not been fully elucidated, and the management of TON remains controversial. In this review article, I review the recent literature regarding TON and discuss how to manage indirect TON.

We experienced one case of lateral orbitotomy(Berke's operation) in intraorbital tumor. We performed diagnostic studies for tumor location and vasculature in relation to eyeball and optic nerve, ie, orbital CT and orbital venogram. Tumor mass located in superior lateral region of orbit. Tumor mass was removed completely and successfully through 35 mm lateral skin incision.

Orbital meningioma is relatively rare. A case of intraorbital meningioma arising from optic nerve sheath is presented, which extended intracranially through the optic canal. Transfrontal intradural and extradural approach under the operating microscope is the best successful exposure for the orbital meningioma when there is suspected intracranial extension of the tumor.
