The Maddox rod is a staple in the assessment of strabismus. However, its optics mechanism is puzzling. How is it that an orthogonal line focus is formed? Surprisingly, few texts offer an explanation and those that do either provide insufficient detail, contain misleading information or are difficult to follow.

Purpose: To characterize intraocular pressure (IOP) reduction, effect duration, and side effect profile of repeat selective laser trabeculoplasty (SLT) used as primary stand-alone treatment for open-angle glaucoma (OAG). The secondary aim was to investigate covariates associated with treatment response to SLT.

Design: Retrospective chart review.

Purpose: To investigate the association between cardiovascular disease and baseline structural defects and disease progression in glaucoma.

Design: Prospective, longitudinal study of preperimetric and perimetric glaucoma.

Participants: Two thousand six hundred twenty-eight eyes from 1314 participants recruited to the Progression Risk of Glaucoma: Relevant SNPs with Significant Association (PROGRESSA) study were evaluated for baseline and longitudinal structural thinning using spectral-domain OCT and for visual field progression on Humphrey visual field (HVF) assessment.

Purpose: Tube perforations are a common method of achieving early intraocular pressure control with ligated glaucoma drainage devices (GDDs). Our purpose was to investigate how bending GDD tubes affects the performance of needle perforations.

Design: Experimental report.

Glaucoma drainage tubes have become increasingly popular in the surgical management of uncontrolled glaucoma. Flow restriction is essential to prevent early postoperative hypotony with non-flow restrictive glaucoma drainage devices. Herein, we describe a new way of using a 3-0 Supramid suture as an intraluminal stent.

Glaucoma, a disease characterized by progressive optic nerve degeneration, can be prevented through timely diagnosis and treatment. We characterize optic nerve photographs of 67,040 UK Biobank participants and use a multitrait genetic model to identify risk loci for glaucoma. A glaucoma polygenic risk score (PRS) enables effective risk stratification in unselected glaucoma cases and modifies penetrance of the MYOC variant encoding p.

Primary open-angle glaucoma is the leading cause of irreversible blindness worldwide, and intraocular pressure reduction remains the only proven treatment strategy. Elevated intraocular pressure occurs as the result of impaired aqueous humor outflow. Both a passive model and a dynamic model have been used to explain trabecular outflow resistance.

Purpose: To investigate which clinical measures influence whether an individual demonstrates earliest glaucomatous structural progression on peripapillary retinal nerve fiber layer (pRNFL) or macular ganglion cell-inner plexiform layer (mGCIPL).

Design: Prospective, longitudinal cohort study.

Participants: Two hundred seventy-one eyes from 207 individuals with statistically significant evidence of glaucomatous progression on OCT Guided Progression Analysis (GPA) software were drawn from a total of 1271 eyes from 686 individuals categorized as glaucoma suspect or having early manifest glaucoma undergoing glaucoma surveillance.

Importance: The demand for glaucoma care is projected to increase significantly with the ageing population.

Background: To characterize trends in Australian practice patterns for glaucoma management over the 15-y period between 2003 and 2017.

Design: Retrospective audit.

Purpose: The ganglion cell analysis (GCA) of the CIRRUSTM HD-OCT (Carl Zeiss, Meditec; Dublin, CA) provides measurement of the macular ganglion cell-inner plexiform layer (GCIPL) thickness. This study determined the frequency of scan artefacts and errors in GCIPL imaging in individuals undergoing HD-OCT surveillance for glaucoma.

Method: A total of 1439 eyes from 721 subjects enrolled in a prospective study assessing predictors of glaucoma progression underwent macular GCIPL imaging with the CIRRUS HD-OCT at recruitment.

Purpose: To compare "total keratometry" measurements with Goggin nomogram adjusted anterior keratometry (GNAK) for toric intraocular lens calculation.

Methods: Routine biometry provided measured total keratometry values from which astigmatism was derived. The Goggin nomogram was applied to anterior keratometry values on the same eyes to provide nomogram-adjusted anterior keratometry values (GNAK) that estimate total corneal astigmatism.

Importance: It is well established from different population-based studies that visual impairment is associated with increased mortality rate. However, to our knowledge, the association of visual impairment with increased mortality rate has not been reported among indigenous Australian individuals.

Objective: To assess the association between visual impairment and 10-year mortality risk among the remote indigenous Australian population.

Cataract surgery is the most commonly performed surgical procedure in many developed countries. Postoperative endophthalmitis is a rare complication with potentially devastating visual outcomes. Currently, there is no global consensus regarding antibiotic prophylaxis in cataract surgery despite growing evidence of the benefits of prophylactic intracameral cefuroxime at the conclusion of surgery.

Article Synopsis
  • - The study examined the 10-year all-cause mortality rate among Indigenous Australians over 40 years old in Central Australia, finding a mortality rate of 29.3%, which is significantly higher than the general Australian population.
  • - Mortality rates increased with age: 14.2% for ages 40-49, 22.6% for 50-59, and 50.3% for those 60 and older, while gender differences in mortality were negligible except for adjustments related to visual acuity.
  • - A reduction in visual acuity was linked to a higher mortality rate, with a 5% increase in the chance of death for each line decreased on a vision test, highlighting the need for

Lymphoid hyperplasia (LH) is a benign lymphoproliferative disorder that, in a minority of cases, may be associated with concurrent or metachronous non-Hodgkin lymphoma. LH cases are further subdivided into "reactive" and "atypical" categories based on the presence or absence of unequivocal malignant features. With improving molecular diagnostic technologies, "reactive" LH is by far the most common category of LH, with atypical LH accounting for only a small minority of specimens.

Purpose: To present the radiological and clinical features of primary lacrimal gland pleomorphic adenoma (PLGPA).

Methods: Thirty-seven consecutive PLGPAs presenting to two hospitals in Japan were reviewed.

Results: PLGPA cases had 15 men and 22 women with a mean age of 51.

Recent studies have supported the hypothesis that exposure to established cardiovascular risk factors in early life predisposes to the development of adult cardiovascular disease. Retinal imaging is an emerging technique which facilitates non-invasive, accurate and reproducible assessment of the retinal microvasculature. The assessment may be in the form of static vascular calibre measurements and assessment of the vascular geometry or dynamic structural and functional assessments.

Taxanes are a class of microtubule stabilising agents used to treat a wide range of malignancies. Taxane drug-induced cystoid macula oedema (TDICMO) is a known but rare complication of therapy. First reported with Docetaxel in 2003 and Paclitaxel in 2007, there are currently less than 20 cases of TDICMO in the literature.

IgG4-related ophthalmic disease is increasingly widely recognized. Moreover, IgG4 staining can occur in other inflammatory diseases. The authors report a case of IgG4 staining of an enlarged, inflamed levator palpebrae superioris in a patient with a past history of thyroid eye disease.

Aim: To review the efficacy of intraorbital corticosteroid injection for the treatment of IgG4-related ophthalmic disease (IgG4-ROD).

Methods: This study was a retrospective twin-centre histopathology review and observational case series. A chart review was undertaken for 10 cases of biopsy-confirmed IgG4-ROD treated with intraorbital corticosteroid injection.

In recent years, IgG4-related ophthalmic disease (IgG4-ROD) has emerged as a common cause of orbital inflammation, accounting for a substantial proportion of idiopathic orbital inflammation and lymphoid hyperplasia. The last pooled analysis of published cases was conducted in 2012, but a large number of new cases have been added to the literature since then. In this review, we present the demographic, clinical, histological, and treatment data for 172 published cases of biopsy-confirmed IgG4-ROD.
