Acute subperiosteal orbital haematoma following general anaesthesia in the setting of recent trauma.

Subperiosteal orbital haematoma (SOH) is an uncommon condition that involves bleeding within the potential space between the periosteum and orbital bone. This typically occurs within the superior orbit. If the SOH is large enough it can compress orbital structures and be sight threatening.

Periocular intralymphatic histiocytosis or localized Melkersson-Rosenthal syndrome?

We describe three cases of periocular edema with histopathologic features of intralymphatic histiocytosis without extravascular granulomas. All were elderly males with no other significant medical problems. Previous reports of periocular Melkersson-Rosenthal syndrome are identical clinically, and some reports show illustrations of intralymphatic histiocytosis histopathologically, in addition to other features typical of the syndrome.

An unusual complication of crawford tube insertion.

The authors describe an unusual and challenging complication of bicanalicular (Crawford) stent insertion that has previously never been reported. A 27-year-old man sustained multiple lacerations to the left (L) periocular and facial areas with a glass bottle. He was admitted under the care of the Plastic Surgical team at another institution and underwent repair of the facial, eyelid, and canalicular lacerations in the operating room.

Rating papilloedema: an evaluation of the Frisén classification in idiopathic intracranial hypertension.

The appearance of the optic disc is a key measure of disease status in idiopathic intracranial hypertension (IIH). The Frisén classification describes stages of optic disc swelling (grades 0-5). It is the only classification of papilloedema, and is used internationally in clinical and research practice.

The significance of DNA mismatch repair genes in the diagnosis and management of periocular sebaceous cell carcinoma and Muir-Torre syndrome.

Objective: The aims of this study were to determine the significance of expression of DNA mismatch repair proteins in detecting systemic malignancies in a series of patients with periocular sebaceous cell carcinoma and to determine the clinical characteristics and frequency of Muir-Torre syndrome in this cohort.

Design: The study was a retrospective non-comparative interventional case series.

Participants: 31 patients with histologically proven sebaceous cell carcinoma of the eyelid participated in the study.

Correlation of retinal nerve fiber layer measured by scanning laser polarimeter to visual field in ischemic optic neuropathy.

Objective: To evaluate the relationship between retinal nerve fiber layer (RNFL) measurement with scanning laser polarimetry (SLP) and standard automated perimetry (SAP) in nonarteritic anterior ischemic optic neuropathy (NAION).

Methods: In this prospective observational case series, all subjects (28 eyes with NAION) underwent SAP and SLP. The RNFL retardation measurements and visual field test points were grouped into 6 corresponding sectors.

Glaucoma prescribing trends in Australia and New Zealand.

Purpose: To summarize current practice styles and patterns associated with glaucoma management in ophthalmologists of Australia and New Zealand as derived from a survey.

Method: A questionnaire was sent to all Australian and New Zealand ophthalmologists, which anonymously assessed demographic characteristics and prescribing patterns for each major class of glaucoma medication.

Results: A total of 761 questionnaires were sent with a response rate of 51%.

Glaucoma management trends in Australia and New Zealand.

Background: To describe self-reported patterns of care for glaucoma of ophthalmologists in Australia and New Zealand and summarize current practice styles and patterns associated with glaucoma management.

Methods: A questionnaire of glaucoma management practices was mailed to all ophthalmologists registered with the Royal Australian and New Zealand College of Ophthalmologists in June 2003. The questionnaire assessed practice preferences for medical management, examination techniques and indications for surgery.

Pseudophakic retinal detachment after phacoemulsification cataract surgery: Ten-year retrospective review.

Purpose: To determine the risk for rhegmatogenous retinal detachment (RRD) after phacoemulsification.

Setting: Private and public facility, Auckland, New Zealand.

Methods: A retrospective study of 1793 consecutive patients having cataract surgery by phacoemulsification was performed.

Giant cell arteritis.

Giant cell arteritis (GCA) is an immune-mediated vasculitis, affecting medium- to large-sized arteries, in individuals over the age of 50 years. Visual loss is a frequent complication of GCA, and once it occurs it tends to be both permanent and profound. Although major advances have been made in recent years in genetics, molecular biology and the description of the vessel wall morphology, the aetiology and pathogenesis of GCA are still incompletely understood.

Correlation of the multifocal visual evoked potential and standard automated perimetry in compressive optic neuropathies.

Purpose: To evaluate the relationship between abnormalities detected by the multifocal visual-evoked potential (mfVEP) compared with those detected by static achromatic automated perimetry in patients with compressive optic neuropathy.

Methods: Fifteen patients of mean age 50.8 years, with known compressive optic neuropathy from chiasmal lesions, underwent monocular mfVEP and 24-2 SITA-standard Humphrey visual field (HVF; Carl Zeiss Meditec, Dublin CA) testing in each eye.

Comparison of the Proview pressure phosphene tonometer performed by the patient and examiner with the Goldmann applanation tonometer.

Objective: To compare the results of Proview pressure phosphene tonometry (PPPT) performed by the patient and an examiner with Goldmann applanation tonometry (GAT).

Methods: A comparative case series of 96 (192 eyes) consecutive patients from a glaucoma clinic was conducted. Intraocular pressure (IOP) was measured with GAT by one examiner, PPPT by another examiner, and PPPT by the patient.
