Recent advances in OCT imaging of the lamina cribrosa [PDF]

British Journal of Ophthalmology, 2014
The lamina cribrosa (LC) is believed to be the site of injury to retinal ganglion cell axons in glaucoma. The ability to visualise this structure has the potential to help increase our understanding of the disease and be useful in the early detection of glaucoma.

Reproducibility of in-vivo OCT measured three-dimensional human lamina cribrosa microarchitecture. [PDF]

PLoS ONE, 2014
To determine the reproducibility of automated segmentation of the three-dimensional (3D) lamina cribrosa (LC) microarchitecture scanned in-vivo using optical coherence tomography (OCT).Thirty-nine eyes (8 healthy, 19 glaucoma suspects and 12 glaucoma ...

Perilymph Gusher in Cochlear Implantation Surgery: An Algorithm for Management

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective Perilymph leak is considered a major complication of cochlear implantation (CI) surgery and can lead to surgical difficulties and postoperative morbidities. This study is aimed to formulate an algorithm for better management of perilymph leak in cases of CI. Methods This is a retrospective study conducted in our tertiary institute on

Lamina Cribrosa Depth in Healthy Eyes

Investigative Opthalmology & Visual Science, 2014
To investigate the characteristics of the lamina cribrosa (LC) depth in healthy eyes using enhanced depth imaging (EDI) spectral-domain optical coherence tomography (SD-OCT).Serial horizontal B-scans of the optic nerve head were obtained using EDI SD-OCT for both eyes of 150 healthy subjects.

Interpreting the structure–function relationship in high myopia‐associated glaucoma: A review

Acta Ophthalmologica, EarlyView.
Abstract Visual field (VF) interpretation in high myopia‐associated glaucoma (HMG) is challenging due to frequent structure–function discordance and coexisting myopia‐related changes. These changes may reduce the reliability of conventional structure–function mapping and increase the risk of misclassifying non‐glaucomatous VF abnormalities as ...

Three dimensional analysis of the lamina cribrosa in glaucoma [PDF]

British Journal of Ophthalmology, 2004
Structural changes in the lamina cribrosa have been implicated in the pathogenesis of glaucomatous optic atrophy. The aim of this study was to determine a measure the surface variability of the cup floor in normal subjects and patients with glaucoma.A sample of age matched normal subjects (NN), patients with low tension glaucoma (LTG), and primary open

Australian and New Zealand Glaucoma Society (ANZGS) Consensus on Interventional Glaucoma

Clinical &Experimental Ophthalmology, EarlyView.
ABSTRACT Background Traditional reactive ‘wait and see’ approaches in glaucoma management often result in unacceptable rates of permanent vision loss. This consensus defines a proactive ‘interventional glaucoma’ framework tailored for the Australian and New Zealand healthcare context. Methods A modified Delphi consensus process was utilised, consisting

An eye on long‐duration spaceflight: Controversies, countermeasures and challenges

Experimental Physiology, EarlyView.
Abstract Space flight‐associated neuroocular syndrome (SANS) is a consequence of long‐duration space flight and is detected in two‐thirds of astronauts. In‐flight, this can cause a change in the refraction of the eyes, requiring graded hypermetropic ‘superfocus adjustable’ glasses, optic nerve head oedema and choroidal folds.
