Abstract
OBJECTIVE To assess the long-term efficacy and safety of oral saffron, a natural antioxidant, in treating mild/moderate age-related macular degeneration (AMD). METHODS AND ANALYSIS Open-label, extension trial of 93 adults (>50 years) with mild/moderate AMD and vision >20/70 Snellen equivalent in at least 1 eye. Exclusion criteria included confounding visual lesions or significant gastrointestinal disease impairing absorption.Participants were given oral saffron supplementation (20 mg/day) for 12 months. Those already consuming Age-Related Eye Diseases Study (AREDS) supplements or equivalent maintained these.Primary outcomes included changes in multifocal electroretinogram (mfERG) response density and latency, and changes in best-corrected visual acuity (BCVA). Secondary outcomes included safety outcomes, changes in mfERG and BCVA among participants on AREDS supplements and changes in microperimetry. RESULTS At 12 months, mean mfERG response density was significantly higher in rings 1, 2 and overall (p<0.001 for all) but not in rings 3-6, and there was no difference in response between those taking AREDS supplements and those not (p>0.05). Mean mfERG latency was not significantly different in any of rings 1-6 or overall (p>0.05 for all), again with no difference between those taking AREDS supplements or not (p>0.05). Mean BCVA was 1.6 letters worse (p<0.05) with no difference between those on AREDS supplements or not, and this may have been related to cataract progression. No saffron-related serious adverse events were detected. CONCLUSION Saffron supplementation modestly improved mfERG responses in participants with AMD, including those using AREDS supplements. Given the chronic nature of AMD, longer-term supplementation may produce greater benefits.

Abstract
BACKGROUND Ophthalmology education in medical school has historically neglected the impact of autonomous motivation on student learning and wellbeing. This study aimed to understand ophthalmology educators' consideration and application of student motivation in ophthalmology medical education. MATERIAL AND METHODS Lead ophthalmology educators from Australian and New Zealand medical schools participated in an online semi-structured in-depth interview. Interview transcripts were analysed using thematic analysis. Codes were generated and aligned into overarching themes. FINDINGS Six educators participated in the study. Five main themes arose from the transcripts: the lack of explicit consideration of student motivation, implicit consideration of motivation in curriculum design and in teaching practices, the impact of innovation on motivation and the relationship between teacher and student motivation. Participants also commented on trends in ophthalmology education including generalists' confidence in managing ophthalmic disease, the role of fundoscopy in medical education and time pressure on ophthalmology in medical schools. CONCLUSION There has only been an implicit instead of explicit consideration of motivation in ophthalmology education in medical school, which leaves an unfulfilled potential for teaching practices to impact the affective along with cognitive and metacognitive aspects of learning. This study highlights the need for motivation to be explicitly incorporated into the development of teaching practices and curriculum reform.

Abstract
Knowledge of aquifer dynamics, including groundwater storage changes, is key to effective groundwater resource and reservoir management. Resolving and accurate modeling of these processes requires knowledge of subsurface poroelastic properties and lateral heterogeneity within units of interest. Computationally demanding methods for determining lateral heterogeneity in poroelastic properties exist but remain difficult to practically employ. The InSAR-based detection of uplift over a New Mexico well with a casing breach provides an opportunity to determine poroelastic properties using a tractable 2D analytical plane strain solution for surface uplift created by a pressurized reservoir with overburden. Using a Bayesian inversion framework, we calculate poroelastic properties under deep (depth of well-screen) and shallow (depth of well-breach) conditions. We find that shallow injection is necessary to produce the observed deformation. However, pressure-varying forward solutions for uplift are required to reproduce the temporal evolution of deformation. For this we use realistic shallow poroelastic properties and well dynamics, which reflect the evolving injection conditions at the well breach as the casing further erodes. Analysis of individual interferograms or InSAR time series may provide insights into shallow subsurface heterogeneity or anomalous injection conditions at operating wells more rapidly than scheduled field inspections.

Abstract
The full-field electroretinogram (ERG) is a mass electrophysiological response to diffuse flashes of light and is used widely to assess generalized retinal function. This document, from the International Society for Clinical Electrophysiology of Vision (ISCEV), presents an updated and revised ISCEV Standard for clinical ERG testing. Minimum protocols for basic ERG stimuli, recording methods and reporting are specified, to promote consistency of methods for diagnosis, monitoring and inter-laboratory comparisons, while also responding to evolving clinical practices and technology. The main changes in this updated ISCEV Standard for clinical ERGs include specifying that ERGs may meet the Standard without mydriasis, providing stimuli adequately compensate for non-dilated pupils. There is more detail about analysis of dark-adapted oscillatory potentials (OPs) and the document format has been updated and supplementary content reduced. There is a more detailed review of the origins of the major ERG components. Several tests previously tabulated as additional ERG protocols are now cited as published ISCEV extended protocols. A non-standard abbreviated ERG protocol is described, for use when patient age, compliance or other circumstances preclude ISCEV Standard ERG testing.

Abstract
Glaucoma remains a frequent serious complication following cataract surgery in children. The optimal approach to management for 'glaucoma following cataract surgery' (GFCS), one of the paediatric glaucoma subtypes, is an ongoing debate. This review evaluates the various management options available and aims to propose a clinical management strategy for GFCS cases. A literature search was conducted in four large databases (Cochrane, PubMed, Embase, and Web of Science), from 1995 up to December 2021. Thirty-nine studies-presenting (1) eyes with GFCS; a disease entity as defined by the Childhood Glaucoma Research Network Classification, (2) data on treatment outcomes, and (3) follow-up data of at least 6 months-were included. Included papers report on GFCS treated with angle surgery, trabeculectomy, glaucoma drainage device implantation (GDD), and cyclodestructive procedures. Medical therapy is the first-line treatment in GFCS, possibly to bridge time to surgery. Multiple surgical procedures are often required to adequately control GFCS. Angle surgery (360 degree) may be considered before proceeding to GDD implantation, since this technique offers good results and is less invasive. Literature suggests that GDD implantation gives the best chance for long-term IOP control in childhood GFCS and some studies put this technique forward as a good choice for primary surgery. Cyclodestruction seems to be effective in some cases with uncontrolled IOP. Trabeculectomy should be avoided, especially in children under the age of one year and children that are left aphakic. The authors provide a flowchart to guide the management of individual GFCS cases.

Abstract
Purpose To assess the measurement properties of the Attitudes to Gene Therapy for the Eye (AGT-Eye) instrument among Australian adults with inherited retinal diseases (IRDs) and parents/caregivers of people with IRDs. Constructs of interest included sources of information, knowledge of treatment methods, awareness of treatment outcomes, and perceived value of gene therapy for IRDs. Methods A cross-sectional, self-reported, 30-item questionnaire was administered in English from January to June 2021. It was predominantly conducted online with phone and paper alternatives available. Rating scale models were generated separately for each of the four subscales to assess fit, discrimination, and differential item functioning of the items, as well as targeting, reliability, and precision of the subscales. Principal components analysis was used to assess dimensionality. Results Responses from 681 participants (87.1% online, 12.9% phone/mail) were included (ages 18-93 years; 51.7% female). Removal of two poorly performing items slightly improved subscale properties. Item reliability was high for each of the subscales; however, person reliability was suboptimal, with limited ability to stratify participants according to traits (person separation coefficient < 1.8 for each subscale). There was no evidence of differential item functioning by gender, online completion, or patient/caregiver status. Evidence of multidimensionality was detected for two subscales. Conclusions Four subscales of the AGT-Eye will be used to analyze operational knowledge and perceived value of ocular gene therapy in Australia. Measurement properties may be improved with the generation of additional items. Translational Relevance Physicians can use the AGT-Eye to assess knowledge and expectations of potential recipients of ocular gene therapy for IRDs.

Abstract
INTRODUCTION Voretigene neparvovec-rzyl (Luxturna) was approved by the Australian Therapeutic Goods Administration on 4 August 2020 for the treatment of biallelic mutations in the RPE65 gene, a rare cause of congenital and adult-onset retinal dystrophy (predominantly Leber congenital amaurosis). Previous studies have shown that individuals who might participate in gene therapy trials overestimate clinical effect and underestimate risks. However, little is known about the perspectives of patients who may be offered approved gene therapy treatment for ocular conditions (as distinct from participating in clinical trials of gene therapy). The main objective of this study is to develop a tool to assess knowledge, attitudes and perceptions of approved and future genetic therapies among potential recipients of ocular gene therapy. In addition, we aim to assess the quality of life, attitudes towards clinical trials and vision-related quality of life among this cohort. METHODS AND ANALYSIS A new 'Attitudes to Gene Therapy for the Eye' tool will be developed following consultation with people with inherited retinal disease (IRD) and content matter experts. Australians with IRD or their guardians will be asked to complete an internet-based survey comprising existing quality of life and visual function instruments and items for the newly proposed tool. We expect to recruit 500 survey participants from patient support groups, the practices of Australian ophthalmologists who are specialists in IRD and Australian ophthalmic research institutions. Launch is anticipated early 2021. Responses will be analysed using item response theory methodology. ETHICS AND DISSEMINATION This study has received ethics approval from the University of Melbourne (#2057534). The results of the study will be published in a peer-reviewed journal and will be presented at relevant conferences. Organisations involved in recruitment, and the Patient Engagement Advisory committee will assist the research team with dissemination of the study outcomes.

Abstract
A 66-years-old Vietnamese healthy female patient presented with prolonged severe right ocular pain and complete vision loss in that eye. Anterior segment assessment including gonioscopy identified angle-closure configuration. A suspected ciliary body melanoma was seen through the pupil. Posterior segment examination revealed a large tumor mass and 360° retinal detachment (kissing configuration). An ultrasound examination was consistent with a uveal tumor. The painful, blind right eye with a tumor mass was enucleated. Histopathology confirmed a type A uveal spindle cell melanoma associated with total serous retinal detachment without evidence of tumor necrosis, epithelioid cells, scleral, or optic nerve infiltration. There was no evidence of metastasis after 1-year of follow-up. It is critically important to differentiate primary and secondary angle closure, especially in cases with life-threatening ocular malignancy as uveal melanoma.

Abstract
Objective An ongoing third epidemic of retinopathy of prematurity (ROP) is contributed largely by developing nations. We describe a cohort of infants in a single neonatal unit where two limits of oxygen saturation were administered, to show real-world outcomes from trend in neonatology for higher oxygen to improve survival. Methods and analysis This retrospective, comparative study of prospectively collected data in an ROP screening programme included infants indicated by gestational age ≤32 weeks, birth weight <1501 g, ventilation for 7 days or requiring oxygen >1 month, who underwent dilated fundoscopic examination from age 4 weeks, every 2 weeks until full retinal vascularisation. Infants with ROP were examined weekly and treated where indicated. Data were divided into two epochs. Epoch 1 oxygen saturation targets were [88–92%], epoch 2 targets [90–95% (99%)] with allowance of increase to 20% for several hours after procedures. Outcome measures included development of ROP, treatment, mortality, sepsis and intraventricular haemorrhage. Results A total of 651 infants underwent examination between 2003 and 2016. The incidence of ROP in epoch 1 was 29.1% and epoch 2 was 29.3% (p=0.24). ROP progression doubled in epoch 2 (5 vs 11%, p=0.006), proportion of cases treated halved (14% vs 6%, p=0.0005), sepsis was halved (78.5% vs 41.2%, p<0.0001) and intraventricular haemorrhage doubled (20.2% vs 43.8%, p=0.0001) in epoch 2. Mortality was 4% and 0% in epochs 1 and 2, respectively. Conclusion Incidence of ROP did not differ, although ROP cases that worsened doubled with higher oxygen targets. ROP cases requiring treatment decreased, as did sepsis and mortality. Intraventricular haemorrhage cases doubled.

Abstract
Background Over 1 billion people suffer from chronic respiratory diseases such as asthma, COPD, rhinitis and rhinosinusitis. They cause an enormous burden and are considered as major non-communicable diseases. Many patients are still uncontrolled and the cost of inaction is unacceptable. A meeting was held in Vilnius, Lithuania (March 23, 2018) under the patronage of the Ministry of Health and several scientific societies to propose multisectoral care pathways embedding guided self-management, mHealth and air pollution in selected chronic respiratory diseases (rhinitis, chronic rhinosinusitis, asthma and COPD). The meeting resulted in the Vilnius Declaration that was developed by the participants of the EU Summit on chronic respiratory diseases under the leadership of Euforea. Conclusion The Vilnius Declaration represents an important step for the fight against air pollution in chronic respiratory diseases globally and has a clear strategic relevance with regard to the EU Health Strategy as it will bring added value to the existing public health knowledge.

Abstract
Open-angle glaucoma (OAG) is a major cause of blindness worldwide. To identify new risk loci for OAG, we performed a genome-wide association study in 3,071 OAG cases and 6,750 unscreened controls, and meta-analysed the results with GWAS data for intraocular pressure (IOP) and optic disc parameters (the overall meta-analysis sample size varying between 32,000 to 48,000 participants), which are glaucoma-related traits. We identified and independently validated four novel genome-wide significant associations within or near MYOF and CYP26A1, LINC02052 and CRYGS, LMX1B, and LMO7 using single variant tests, one additional locus (C9) using gene-based tests, and two genetic pathways - "response to fluid shear stress" and "abnormal retina morphology" - in pathway-based tests. Interestingly, some of the new risk loci contribute to risk of other genetically-correlated eye diseases including myopia and age-related macular degeneration. To our knowledge, this study is the first integrative study to combine genetic data from OAG and its correlated traits to identify new risk variants and genetic pathways, highlighting the future potential of combining genetic data from genetically-correlated eye traits for the purpose of gene discovery and mapping.

Abstract
Positron emission tomography (PET) and fluorescence labelling have been used to assess the pharmacokinetics, biodistribution and eventual fate of a hydrogel‐forming nonapeptide, FEFKFEFKK (F9), in healthy mice, using 18F‐labelled and fluorescein isothiocyanate (FITC)‐labelled F9 analogues. F9 was site‐specifically radiolabelled with 2‐[18F]fluoro‐3‐pyridinecarboxaldehyde ([18F]FPCA) via oxime bond formation. [18F]FPCA‐F9 in vivo fate was evaluated both as a solution, following intravenous administration, and as a hydrogel when subcutaneously injected. The behaviour of FITC‐F9 hydrogel was assessed following subcutaneous injection. [18F]FPCA‐F9 demonstrated high plasma stability and primarily renal excretion; [18F]FPCA‐F9 when in solution and injected into the bloodstream displayed prompt bladder uptake (53.4 ± 16.6 SUV at 20 minutes postinjection) and rapid renal excretion, whereas [18F]FPCA‐F9 hydrogel, formed by co‐assembly of [18F]FPCA‐F9 monomer with unfunctionalised F9 peptide and injected subcutaneously, showed gradual bladder accumulation of hydrogel fragments (3.8 ± 0.4 SUV at 20 minutes postinjection), resulting in slower renal excretion. Gradual disaggregation of the F9 hydrogel from the site of injection was monitored using FITC‐F9 hydrogel in healthy mice (60 ± 3 over 96 hours), indicating a biological half‐life between 1 and 4 days. The in vivo characterisation of F9, both as a gel and a solution, highlights its potential as a biomaterial.

Abstract
Saffron (Crocus savitus) is a Middle-Eastern herb with strong antioxidant properties. Its major constituents, safranal, crocin, and crocetin, are also antioxidants and bear structural similarities to other well-known natural antixodant substances, such as zeaxanthin. Given the role of oxidative stress in many diseases, considerable interest has been shown into the potential role of saffron supplementation as a treatment for a range of diseases. In vitro and animal studies have provided evidence that saffron and its constituents may be potent therapies for a range of pathologies, including Alzheimer's disease, age-related macular degeneration (AMD) and cardiac ischemia. Whether these findings translate into clinical efficacy, however, has as of yet been incompletely assessed. This makes assessing the role of saffron supplementation in these diseases difficult. Here, we review the current human clinical evidence supporting saffron supplementation as a treatment for a range of pathologies and the underlying science supporting its use.

Abstract
Aim The aim of this article is to evaluate the rate of patients developing sustained elevated intraocular pressure (IOP) after ranibizumab (Lucentis) intravitreal (IVT) injections. Design This is a retrospective study. Participants Charts of 192 consecutive patients receiving Lucentis for age-related macular degeneration (AMD) were retrospectively reviewed. Materials and methods We enrolled patients with at least two IOP measurements between injections. Elevated IOP was defined as >21 mm Hg with an increase of at least 20% from baseline. Noninjected contralateral eyes of the same patient cohort were used as control. Main outcome measures Primary outcome was defined as elevated IOP. Secondary outcomes were presence and type of glaucoma, number of injections, and time to IOP elevation. Results Elevated IOP occurred at a significantly higher rate in eyes receiving IVT ranibizumab (7.47%; n = 9) compared with control (0.93%; n = 1). Patients with preexisting glaucoma or ocular hypertension (OHT) were more likely to develop elevated IOP after IVT ranibizumab injection. Conclusion Intravitreal ranibizumab injections are associated with sustained IOP elevation in some eyes.

Abstract
PURPOSE To evaluate innovative educational strategies that help optimize ophthalmology teaching in a crowded medical curriculum. The knowledge acquisition and perceptions of medical students undertaking the revised competency-based curriculum were compared with the prior content-based curriculum within the Sydney Medical Program. DESIGN A mixed-methods research design was employed to include both quantitative and qualitative dimensions in evaluating the revised curriculum with medical students (n = 328) undergoing their ophthalmology rotation. METHODS Quantitative evaluation was performed with a 20-item multiple choice pre- and post-test of ophthalmic knowledge. A 12-month follow-up test was readministered to compare the long-term retention rate of graduates. Qualitative evaluation was measured with student satisfaction questionnaires. RESULTS In the original curriculum there was an improvement of 19.9% from pre- to post-test scores [2.15; 95% confidence interval (CI), 1.35-2.94; P < 0.001] and a greater improvement of 31.6% from pre- to post-test (3.50; 95% CI, 3.03-3.97; P < 0.001) in the revised curriculum. When assessing retained knowledge at 12 months, students from the revised curriculum scored 11.5% higher than students from the original curriculum (1.56; 95% CI, 0.42-2.71; P = 0.008). In addition, qualitative feedback also improved, with the rotation being highly valued. CONCLUSIONS The revised ophthalmic curriculum resulted in an increase in academic performance and a higher degree of student satisfaction. Given the gradual decline of ophthalmic education in the standard medical school curriculum, our results are timely in providing guidance for minimum ophthalmic curriculum exposure and strategies to improve ophthalmic education in medical schools.

Abstract
BACKGROUND Sly syndrome (Mucopolysaccharidosis Type VII) is an autosomal recessive metabolic storage disorder due to mutations in the GUSB gene encoding the enzyme beta-glucuronidase. Deficiency of this lysosomal enzyme impairs the body's ability to break down the glycosaminoglycans - dermatan, heparan and chondroitin sulphate. Coarse facial features and macrocephaly are typically seen along with bony and skeletal abnormalities, including joint contractures and short stature. Widespread involvement occurs in many other tissues including cardiopulmonary, gastrointestinal, and neurological systems. In view of the rarity of Sly syndrome the ophthalmic features have not been well described. MATERIALS AND METHODS Case report of a 16-year-old boy with Sly syndrome with serial OCT, ocular ultrasound, and electroretinogram (ERG). RESULTS Corneal clouding was present but there was no evidence of glaucoma or optic neuropathy. Despite no clinical evidence of retinopathy, electrophysiology showed reduced photopic and scotopic responses, particularly involving the b-wave which appears progressive. OCT showed normal foveal architecture and normal retinal nerve fiber thickness. CONCLUSION Corneal clouding was noted in this patient and there is no evidence of glaucoma or optic neuropathy. Although retinopathy has not been previously described in Sly syndrome, the ERG changes in this patient suggest that retinopathy may be a feature of MPS VII.

Abstract
2-[(18)F]-Fluoro-3-pyridinecarboxaldehyde ([(18)F]FPCA) is a novel, water-soluble prosthetic group. It's radiochemistry has been developed and fully-automated for application in chemoselective radiolabelling of amino(oxy)-derivatised RI-OR2-TAT peptide, (Aoa-k)-RI-OR2-TAT, using a GE TRACERlab FX-FN. RI-OR2-TAT is a brain-penetrant, retro-inverso peptide that binds to amyloid species associated with Alzheimer's Disease. Radiolabelled (Aoa-k)-RI-OR2-TAT was reproducibly synthesised and the product of the reaction with FPCA has been fully characterised. In-vivo biodistribution of [(18)F]RI-OR2-TAT has been measured in Wistar rats.

Abstract
Abstract
Retinoic acid inducible gene I (RIG-I) is essential for directing and priming the host immune response against many RNA viruses. A diverse small molecule library was used in a cell-based screening approach to identify drug-like compounds that could target the RIG-I signaling pathway and induce downstream IRF3 to drive innate antiviral immunity. We identified small molecule compounds that activate IRF3 to induce discrete subsets of innate immune and antiviral genes. We identified a class of hydroxyquinoline compounds that induce IRF3 activation and innate immunity of cultured cells to decrease viral RNA load and infectious virus production, thereby controlling infection by viruses of the families Flaviviridae, Filoviridae, Orthomyxoviridae, Arenaviridae and Paramyxoviridae. In addition, we identified a second class of benzo-bisthiazole compounds that directly engage and activate RIG-I to promote downstream IRF3 signaling and the expression of innate immune genes, cytokines and chemokines. Importantly, these compounds serve potent immune adjuvant functions to promote the maturation of dendritic cells to enhance antigen presentation and T cell activation. When administered to mice in combination with influenza A virus or West Nile virus vaccine, this compound conferred adjuvant activity to facilitate vaccine-mediated protection of mice from lethal virus challenge under conditions of otherwise suboptimal vaccine dose. Thus, we have identified novel small molecule RIG-I agonists that activate the innate immune response. Our studies reveal the strong potential of developing small molecule RIG-I agonists as broad-spectrum antiviral agents to control RNA virus infection and as adjuvants to potentiate vaccine immunity.

Abstract
Purpose We evaluated the performance of low contrast achromatic (LLA) multifocal visual evoked potentials (mfVEP) in preperimetric glaucoma and compared its diagnostic performance to other early diagnostic tests. We identified the clinically most useful tests and combinations in preperimetric glaucoma. Methods We studied 59 patients with at least one glaucomatous disc, with normal, reliable visual fields in that eye, and 17 normal controls. All participants underwent complete ophthalmic examination including Humphrey visual fields (HVF), short wavelength automated perimetry (SWAP), frequency doubling perimetry (FDT Matrix), Spectralis optical coherence tomography (OCT), Heidelberg retinal tomography (HRT 3), and color stereoscopic optic disc photographs. We recorded mfVEPs using LLA stimulation. Results We studied 85 eyes of 59 patients (64.89 ± 8.15 years) and 34 eyes of 17 controls (64.28 ± 13.06 years; P = 0.64). Heidelberg retinal tomography and LLA mfVEP demonstrated the best sensitivities (50.6% and 51.8%, respectively) in identifying preperimetric glaucoma, and were not significantly different from each other. Both tests had significantly better sensitivity than all other tests (P < 0.0001). Of the eyes, 76.5% were identified by the combination of (any one of) LLA mfVEP and HRT. Sensitivity of the combination was significantly better than any of the individual tests (P < 0.05 for all pairs), or any other combinations of tests, with better negative than positive predictive value. Conclusions The LLA mfVEP test identified approximately 50.6% eyes with preperimetric glaucoma, which was significantly higher than other perimetric methods, and similar to HRT. The combination of LLA mfVEP and HRT had exceptionally high sensitivity of 76.5% for preperimetric glaucoma.

Abstract
BACKGROUND Airway dendritic cells (DC) are critical mediators of lung inflammation in asthma, but the characteristics of DC in the airways of healthy children, and children with asthma, are currently unknown. OBJECTIVE We sought to identify changes in DC subset distribution and activation profile in paediatric asthma using flow cytometry to analyse induced sputum samples obtained from healthy and asthmatic children. METHODS Lung function and atopic status were determined by spirometry and skin prick testing. Induced sputum samples were analysed using 7-colour flow cytometry to identify airway DC populations (lineage(-) HLA-DR(+) sputum cells expressing either CD11c as conventional DC or CD123 as plasmacytoid DC). RESULTS Sputum samples containing lower airway plugs were obtained from 10 healthy children and 8 children with asthma. Lineage(-) HLA-DR(+) DC were successfully identified in all samples, and DC comprised a significantly higher proportion of sputum cells in children with asthma compared with age-matched healthy controls (1.29% vs. 0.67%, P = 0.02). DC expression of the costimulatory marker CD86 was significantly reduced in asthmatic children (73.4% vs. 59.7%, P = 0.04). Sputum DC also included numerous CD1c(+) cells (mean 57% of the total DC population) and low frequencies of cells expressing the subset markers CD141 or CD123, although the proportions of these did not differ between groups. CONCLUSIONS Airway DC can be identified and characterized non-invasively using flow cytometry to analyse paediatric sputum samples. Our data reveal that children with steroid-treated asthma exhibit increased frequency of airway DC with reduced expression of the costimulatory marker CD86, suggesting altered trafficking and/or maturation of these cells either due to asthma or steroid therapies.

Abstract
PURPOSE Phosphoglycerate kinase (PGK) deficiency is an X-linked neurometabolic genetic disorder with variable systemic manifestations. So far, only one patient with retinal anomalies has been reported, but no visual electrophysiology findings were described. We report the first description of visual electrophysiology in a child with PGK deficiency. This provides further information for the site of involvement in the eye. METHOD A case history of a nine-year-old boy with PGK deficiency is reported. RESULTS This patient was diagnosed with PGK deficiency by screening soon after birth, as his mother was a known carrier of a PGK gene mutation. A bone marrow transplant was performed at the age of 9 months. He had two episodes of encephalopathy following the transplant but no acute episode of haemolysis. From the age of 6 years, his vision has been deteriorating. Visual electrophysiology results identified retinal involvement involving both rod and cone dysfunction. The visual evoked potential was normal. CONCLUSIONS Retinal dystrophy may be one of the clinical manifestations of phosphoglycerate kinase deficiency.

Abstract
Ophthalmic medical student education is a cornerstone to improving eye health care globally. We review the current state of the literature, listing barriers to potential best practices for undergraduate ophthalmology teaching and learning within medical curricula. We describe recent advances and pedagogical approaches in ophthalmic education and propose specific recommendations for further improvements and research. Future research should concentrate on developing teaching and learning innovations that may result in a more time- and resource-effective models for interactive and integrated learning. As well as demonstrating that a competency-based approach results not just in better eye health, but also improvements in patient care, education, and medical care in general. By optimizing teaching available through improved evidence-based education, the ultimate goal is to increase medical students' knowledge and produce graduates who are highly trained in eye examination skills, resulting in improved patient eye care through timely diagnosis, referrals, and treatment.

Abstract
IMPORTANCE Infantile cataract surgery bears a significant risk for postoperative glaucoma, and no consensus exists on factors that may reduce this risk. OBJECTIVE To assess the effect of primary intraocular lens implantation and timing of surgery on the incidence of postoperative glaucoma. DATA SOURCES We searched multiple databases to July 14, 2013, to identify studies with eligible patients, including PubMed, MEDLINE, EMBASE, ISI Web of Science, Scopus, Central, Google Scholar, Intute, and Tripdata. We also searched abstracts of ophthalmology society meetings. STUDY SELECTION We included studies reporting on postoperative glaucoma in infants undergoing cataract surgery with regular follow-up for at least 1 year. Infants with concurrent ocular anomalies were excluded. DATA EXTRACTION AND SYNTHESIS Authors of eligible studies were invited to contribute individual patient data on infants who met the inclusion criteria. We also performed an aggregate data meta-analysis of published studies that did not contribute to the individual patient data. Data were pooled using a random-effects model. MAIN OUTCOMES AND MEASURES Time to glaucoma with the effect of primary implantation, additional postoperative intraocular procedures, and age at surgery. RESULTS Seven centers contributed individual patient data on 470 infants with a median age at surgery of 3.0 months and median follow-up of 6.0 years. Eighty patients (17.0%) developed glaucoma at a median follow-up of 4.3 years. Only 2 of these patients had a pseudophakic eye. The risk for postoperative glaucoma appeared to be lower after primary implantation (hazard ratio [HR], 0.10 [95% CI, 0.01-0.70]; P = .02; I(2) = 34%), higher after surgery at 4 weeks or younger (HR, 2.10 [95% CI, 1.14-3.84]; P = .02; I(2) = 0%), and higher after additional procedures (HR, 2.52 [95% CI, 1.11-5.72]; P = .03; I(2) = 32%). In multivariable analysis, additional procedures independently increased the risk for glaucoma (HR, 2.25 [95% CI, 1.20-4.21]; P = .01), and primary implantation independently reduced it (HR, 0.10 [95% CI, 0.01-0.76]; P = .03). Results were similar in the aggregate data meta-analysis that included data from 10 published articles. CONCLUSIONS AND RELEVANCE Although confounding factors such as size of the eye and surgeon experience are not accounted for in this meta-analysis, the risk for postoperative glaucoma after infantile cataract surgery appears to be influenced by the timing of surgery, primary implantation, and additional intraocular surgery.

Abstract
To the authors' knowledge, this case report is the first to describe rod-cone dystrophy in a patient with linear sebaceous nevus syndrome. Because linear sebaceous nevus syndrome is a multisystem disorder, it is important that treatment include an interdisciplinary approach. The electroretinographic findings are characteristic and can be subtle. These findings should be differentiated from the findings in high myopia.

Abstract
OBJECTIVE To investigate the ideal correction of intraocular lens (IOL) power for sulcus implantation. DESIGN Retrospective, comparative case series. PARTICIPANTS The records of 679 patients undergoing cataract surgery from June 2007 to June 2008 were reviewed. INTERVENTION Eyes in this series underwent phacoemulsification and IOL implantation with local anesthesia. Patients in our study population had their IOL power reduced by 0.5 or 1 diopter (D) from that calculated by the SRK-T formula for in-the-bag implantation. The IOL implanted was the foldable 3-piece acrylic Acrysof MA60AC (Alcon Laboratories Inc., Fort Worth, TX). MAIN OUTCOME MEASURES In each case, the difference between actual spherical equivalent (SE) refraction and that predicted by biometry using the SRK-T formula was calculated. RESULTS Posterior capsule tears requiring implantation of IOL in the ciliary sulcus occurred in 36 eyes. When comparing eyes in which the power was reduced by 0.5 D with those in which the reduction was 1.0 D, those with a power reduction of 1.0 D had significantly less unexpected error (0.49 vs. 1.01 D SE). After stratifying eyes by axial length (AL), we found higher unexpected refractive error in short eyes (<22 mm AL). Likewise, eyes with a predicted IOL power >25 D had a greater postoperative refractive error. CONCLUSIONS This is the first comparative clinical review examining adjustment of power of the sulcus-implanted IOL. We found that the IOL power should be adjusted according to the measured AL and predicted IOL power. For patients with a predicted IOL power from 18 to 25 D, power should be reduced by at least 1 D; for lenses >25 D, power should be reduced by 1.5 to 2 D.

Abstract
BACKGROUND AND PURPOSE Central retinal artery occlusion is caused by a platelet-fibrin thrombus or embolic occlusion and is a stroke of the eye. Observational studies suggest that thrombolytics may restore ocular perfusion and visual function. We hypothesized that intravenous tissue-type plasminogen activator (tPA) administered within 24 hours of symptom onset might restore ocular perfusion and visual function. METHODS A placebo-controlled, randomized trial of intravenous tPA versus intravenous saline was performed in patients with clinically defined central retinal artery occlusion within 24 hours of symptom onset. tPA was administered at a total dose of 0.9 mg/kg, with 10% given as a 1-minute bolus and the remainder over 1 hour. An improvement of visual acuity of 3 lines or more was considered significant. RESULTS Twenty-five percent (2 of 8) of the tPA group experienced the primary outcome at 1 week after tPA versus none of the placebo group. One patient had an intracranial hemorrhage. The visual acuity improvement of these 2 patients was not sustained at 6 months. In both patients, tPA was administered within 6 hours of symptom onset. CONCLUSIONS Although essentially a negative study, it does add to the evidence base of reperfusion in central retinal artery occlusion by showing that the time window for intervention is likely to be <6 hours. Reocclusion is a potential problem and may require adjuvant anticoagulation. Future studies should concentrate on determining the efficacy of thrombolytics in the <6-hour time window.

Abstract
There is now convincing evidence that air pollution, especially the particulate matter (PM) fraction, adversely affects children's health. In general, the health effects of traffic-derived PM are well described in children living in high-income countries. Conversely, studies into the health effects of PM from biomass and solid fuels are limited to children in lower-income countries. As PM from different combustion sources have components in common (e.g. elemental black carbon) - are we able to extrapolate from the research performed in different countries under different exposure conditions? Using lung function growth and vulnerability to infection as examples of health effects of global significance to children, this review addresses the question whether high-income-country research into air pollution can inform effects of pollution in low-income countries and vice versa.
