BACKGROUND: Mechanisms of peri-operative ischaemic optic neuropathy remain poorly understood. Both specific pre-operative and intra-operative factors have been examined by retrospective studies, but no animal model currently exists. OBJECTIVES: To develop a rodent model of peri-operative ischaemic optic neuropathy. In rats, we performed head-down tilt and/or haemodilution, theorising that the combination damages the optic nerve. DESIGN: Animal study...

Glaucoma is an optic neuropathy that affects the ganglion cell complex in all its components: cell bodies, dendrites, and axons, the dendritic arbor being the first one damaged. This is the reason why the thickness of the ganglion cell and internal plexiform layers can be taken into account as an early predictor of the glaucomatous changes, along with the retinal nerve fiber layer (RNFL) thickness. However, due to disc tilting and peripapillary atrophy, the RNFL evaluation may be prone to errors in myopic patients...

For over a century, tilted disc syndrome (TDS) has been defined vaguely. The lack of consensus of the terminology arises from the lack of understanding of the pathogenesis of this condition. Also, myopic discs with temporal crescents or peripapillary atrophy (PPA) are histologically indistinguishable from TDS. Therefore, we examined the morphological background of the extreme ONH appearances such as the myopic tilted disc and the TDS by analyzing the posterior segment of the eye from a three-dimensional (3D) perspective...

SIGNIFICANCE: Differentiating papilledema from pseudopapilledema reflecting tilted/crowded optic discs or disc drusen is critical but can be challenging. Our study suggests that spectral-domain optical coherence tomography (OCT) peripapillary retinal nerve fiber layer thickness and retrobulbar optic nerve sheath diameter (ONSD) measured by A-scan ultrasound provide useful information when differentiating the two conditions. PURPOSE: To evaluate the use of A-scan ultrasound and spectral-domain OCT retinal nerve fiber layer thickness (RNFLT) in differentiating papilledema associated with idiopathic intracranial hypertension from pseudopapilledema...

Optical coherence tomography (OCT) has made it possible for clinicians to measure the peripapillary choroidal thickness (ppCT) noninvasively in various ocular diseases. However, the ocular factors associated with the ppCT have not been conclusively determined. The purpose of this study was to determine the relationship between the local ppCT and the axial length, optic disc tilt, and the angle of the papillo-macular position (PMP) in healthy eyes. This was a prospective, observational cross-sectional study of 119 right eyes of 119 healthy Japanese volunteers...

A 70-year-old woman presented with 20/200 visual acuity in the right eye. Multimodal imaging revealed tilted disc syndrome (TDS) with macular serous detachment (MSD) and pigmentary changes at the temporal margin of the optic disc. Subretinal fluid persisted after three monthly intravitreal bevacizumab (Avastin; Genentech, South San Francisco, CA) injections and threshold focal laser photocoagulation. Subsequently, confluent subthreshold argon laser was applied over the entire area of retinal pigment epithelium (RPE) abnormalities, resulting in the resolution of subretinal fluid without recurrence through 3 years of follow-up...

Tilted and rotated appearances are hallmarks of the myopic optic disc. As the eyeball grows axially, the posterior pole elongates not only globally but in a localized manner as well. In this process, the optic disc is pulled towards the deepest point of the elongated eyeball, which might result in a change in optic disc configuration. Thus, we hypothesized that analyzing the variation of posterior pole contour can play a major role in understanding optic disc configuration in myopic subjects. By analyzing consecutive images of swept source OCT coronal sections at the posterior pole, the deepest interface between Bruch's membrane and the choroid could be identified as the deepest point of the eyeball (DPE)...
