Abstract
PURPOSE To determine the incidence, characteristics, disposition, and economic burden of emergency department (ED) visits for ophthalmic trauma in the United States (US). DESIGN Retrospective study. METHODS The Nationwide Emergency Department Sample was used to calculate and characterize ED visits for ophthalmic trauma in the US from 2009 to 2018. Linear regression was used to estimate trends in annual incidence and mean inflation-adjusted ED charges. Logistic regression was used to assess variables associated with inpatient admission. RESULTS There were over 7.3 million ED visits for ophthalmic trauma in the US over the 10 years, with an annual incidence of 233 per 100,000 population. Patients were predominantly male (65 %), 21-44 years old (39 %), and from low-income households (56 %). Only 1 % of patients were hospitalized. Older age, male sex, metropolitan teaching hospitals, and trauma centers were associated with significantly higher odds of inpatient admission. The mean inflation-adjusted ED charge per visit more than doubled over the decade ($1,333 to $3,187) with total charges exceeding $14 billion. Superficial injuries (44 %) and eyelid/orbit wounds (20 %) accounted for the majority of visits. Orbital floor fractures (4 %) and open globe injuries (2 %) accounted for a minority of visits but were responsible for most admissions (49 % and 29 %, respectively) and the highest mean ED charge ($7,157 and $6,808, respectively). CONCLUSIONS Ophthalmic trauma represents an increasingly significant burden to EDs in the US. Preventive efforts should target young males from low socioeconomic backgrounds. Strategies to improve outpatient access and redirect non-urgent injuries may help alleviate costs.

Abstract
PURPOSE To determine the incidence, risk factors, and visual outcomes of cystoid macular edema (CME) after cataract surgery in the United States. DESIGN Retrospective, longitudinal, case-control study. PARTICIPANTS Patients aged ≥ 18 years who underwent phacoemulsification cataract surgery. METHODS The American Academy of Ophthalmology IRIS® Registry (Intelligent Research in Sight) was used to analyze patients who underwent cataract surgery between 2016 and 2019. Patients who received a diagnosis of CME within 90 days after cataract surgery were classified as cases, and the rest were classified as controls. Multivariable logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals (CIs) for risk factors associated with the development of CME as well as poor visual outcome (defined as a best-recorded visual acuity worse than 20/40 Snellen equivalent at postoperative month 12). MAIN OUTCOME MEASURES Incidence, demographics, baseline characteristics, and visual outcomes. RESULTS Of 3.1 million cataract surgeries performed during the study period, CME was diagnosed in 25 595 eyes (0.8%), with an average onset of 6 weeks. Patients with CME were more likely to be male, to be aged < 65 years, to be Black, and to have preexisting diabetic retinopathy. Patients with CME were more likely to have a poor visual outcome (OR, 1.75; 95% CI, 1.66-1.84; P < 0.001), with a mean best-recorded visual acuity of 20/30 at postoperative month 12 (compared with 20/25 for those without CME; P < 0.001). Other factors associated with a poor visual outcome included smoking, Medicaid insurance, non-White race, and baseline ocular comorbidities such as macular degeneration and retinal vein occlusion. CONCLUSIONS Although the incidence of CME after cataract surgery is low and most eyes achieve a visual acuity of 20/40 or better, there are significant outcome disparities that warrant further exploration.

Abstract
PURPOSE To investigate factors associated with prolonged length of stay and high cost among pediatric hospitalizations with a primary ophthalmic diagnosis. METHODS This retrospective, cross-sectional study utilized data on pediatric admissions with a primary ophthalmic diagnosis from the multicenter 2016 Kids' Inpatient Database. Multivariable logistic regression models adjusted for demographic, hospital, and admission characteristics were used to evaluate factors associated with prolonged stay and high cost, defined as exceeding the 75th percentile (>4 days and $12,642, respectively). RESULTS An estimated 6,811 pediatric hospitalizations with a primary ophthalmic diagnosis in the United States in 2016 were included. On adjusted analysis, a prolonged length of stay was more likely with Medicaid (vs. private insurance, OR = 1.19, 95% CI: [1.02, 1.40], p = .03), non-trauma (vs. trauma, OR = 2.77, 95% CI: [2.12, 3.63], p < .001) and urban teaching hospitals (vs. rural, OR = 3.48, 95% CI: [1.04, 11.69], p = .04). A high cost of stay was more likely with higher income levels (Quartile 3 vs. 1, OR = 1.30, 95% CI: [1.02, 1.67], p = .04; Quartile 4 vs. 1, OR = 1.49, 95% CI: [1.08, 2.05], p = .02), private insurance (vs. Medicaid, OR = 1.26, 95% CI: [1.04, 1.53], p = .02), Western hospitals (vs. South, OR = 2.74, 95% CI: [1.83, 4.12], p < .001), and trauma (vs. non-trauma, OR = 3.29, 95% CI: [2.57, 4.21], p < .001). Children and young adults had higher odds of prolonged stay, while adolescents and young adults had higher odds of high cost compared to toddlers (p < .05 for all). CONCLUSIONS Additional work addressing the factors associated with higher resource utilization may help promote the delivery of quality inpatient pediatric eye care.

Abstract
IMPORTANCE It is important to recognize presenting features and factors associated with mortality in abusive head trauma (AHT) owing to the severity of the diagnosis and the necessity for prompt action. OBJECTIVE To describe the prevalence and economic burden of AHT and identify factors associated with mortality. DESIGN, SETTING, AND PARTICIPANTS This retrospective, cross-sectional study used the Nationwide Emergency Department Sample database to identify all emergency department visits in the US for patients younger than 5 years with a primary diagnosis of abusive head trauma between January 1, 2006, and December 31, 2018. This study was conducted in 2021. MAIN OUTCOMES AND MEASURES Prevalence, demographic characteristics, clinical characteristics, mortality, and economic burden associated with AHT. Weighted national estimates were calculated using sampling weights provided in the Nationwide Emergency Department Sample database. RESULTS From 2006 to 2018, there were an estimated 12 287 cases of emergency department visits in the US for patients younger than 5 years with a primary diagnosis of AHT. The estimated number of AHT cases decreased by 672 (95% CI, 403-940; P < .001) from 2006 to 2018. The incidence decreased by 6.7% each year (incidence rate ratio, 0.93; 95% CI, 0.93-0.94; P < .001) between 2006 and 2018. During the course of a hospital visit, 646 patients (5.3%) died. The majority of patients with a diagnosis of AHT were younger than 1 year (n = 7046; 57.3%), were male (n = 7268; 59.2%) and had Medicaid insurance (n = 8585; 70.0%). After controlling for demographic characteristics, factors associated with increased mortality were age greater than 1 year (odds ratio [OR], 2.45; 95% CI, 1.50-3.99; P < .001), first or second income quartile (OR, 1.78; 95% CI, 1.08-2.91; P = .02), midwestern United States (OR, 2.04; 95% CI, 1.04-4.00; P = .04), level 1 trauma center (OR, 2.69; 95% CI, 1.07-6.75; P = .04), orbital fracture (OR, 15.38; 95% CI, 2.41-98.18; P = .004), cerebral edema (OR, 8.49; 95% CI, 5.57-12.93; P < .001), intracranial hemorrhage (OR, 4.27; 95% CI, 1.71-10.67; P = .002), hypoxic ischemic brain injury (OR, 4.16; 95% CI, 2.13-8.10; P < .001), skull fractures (OR, 3.20; 95% CI, 1.76-5.82; P < .001), subarachnoid hemorrhage (OR, 2.43; 95% CI, 1.22-4.83; P = .01), retinal hemorrhage (OR, 2.17; 95% CI, 1.40-3.38; P < .001), and subdural hemorrhage (OR, 2.05; 95% CI, 1.05-3.98; P = .04). CONCLUSIONS AND RELEVANCE This study's findings suggest that health care disparities may be present in the treatment of AHT. Recognizing factors suggested in this investigation to be associated with higher mortality, public health efforts should be targeted toward low-income areas and in the midwestern United States.

Abstract
PURPOSE To characterize demographics and trends in oculoplastics-related emergency department (ED) visits. METHODS The authors conducted a retrospective, multiyear study of the nationwide ED sample database. The nationwide ED sample was queried for oculoplastics-related International Classification of Disease-ninth revision codes identified from a comprehensive list and categorized based on anatomic location, urgency, and trauma status. Demographics, clinical characteristics, procedure requirement, and cost data were analyzed. Variables associated with inpatient admission were assessed using univariate and multivariate logistic regression. RESULTS The authors identified an estimated 4.2 million ED visits in the United States with oculoplastics-related primary diagnoses, of which pathology was 80.8% eyelid/adnexal, 17.4% orbital, and 1.74% lacrimal. Overall, 31.3% of the visits were deemed to be nonurgent. Orbital pathology was more likely to be caused by trauma (70.6%), to be urgent (98.0%), and to require a procedure (45.6%) (p < 0.001). While less than 5% of all patients required hospitalization, predictors for inpatient admission were urgent diagnoses (odds ratio, 14.9; CI, 13.7-16.1), presentation to a level 1 trauma center (odds ratio, 3.19; CI, 2.7-3.79), and presence of orbital pathology (odds ratio, 6.09; CI 5.73-6.47). Incidence of ED visits decreased in all categories; however, total inflation-adjusted charges increased. CONCLUSIONS Over half of oculoplastics-related ED visits are for trauma, with orbital pathology being less common but requiring a high level of care. Although trends show a potentially decreasing incidence of oculoplastics-related ED visits, increasing costs and high proportion of nonurgent visits pose an opportunity for mitigating periocular trauma and increasing outpatient access to care, respectively.

Abstract
Mining is vital for human sustenance and a crucial sector in the state economy. However, its impacts on the environment and biodiversity cannot be underestimated. Which are potent to the attract government's attention. Environment and wildlife are subject to the harmful impacts of mining and its related activities. In this study, districts, namely Mardan and Mohmand have been targeted with respect to mining impacts. The assessment was carried out on wildlife adversely affected by the mining sector. The fauna has been keenly observed to bring the calculated risks and threat perception of the regional wildlife. Total 9 species of mammals, 21 species of birds, were recorded in District Mardan. While in District Mohmand 2 species of mammals, 9 species of birds, and 4 species of reptiles were studied. The Study explored that mining primarily responsible for land degradation. Which lead to food and agriculture losses. Several other factors like blasting, pollution, hunting, deforestation, habitat loss was also observed. Deforestation surfaced one of the major causes for extinction of fauna in the said region. preemptive measures are needed to seize the man-made catastrophe.

Abstract
Abstract
Background
Certain factors such as left ventricular (LV) geometry and loading conditions affect the validity and reliability of LV ejection fraction (LVEF) as a true measure of LV contractility. LV global longitudinal strain (LVGLS) is less sensitive to these factors, and it has superior prognostic performance in patients with acquired heart disease. The purpose of this study was to determine the clinical implications of using LVGLS (instead of LVEF) as the measure of LV systolic function in adults with Ebstein anomaly given the inherent abnormalities of LV geometry and preload in this population.
Methods
Retrospective cohort study of 673 adults with Ebstein anomaly (2003–2018). We hypothesized that LVGLS had a stronger correlation with heart failure indices and transplant-free survival compared to LVEF.
Results
Compared to LVEF, LVGLS had stronger correlations with cardiac index (r=0.46 vs r=0.21, p=0.007), glomerular filtration rate (r=0.57 vs r=0.19, p<0.001), and NT-proBNP (r=−0.64 vs r=−0.41, p=0.01). Of 673 patients, 514 (76%) had normal LV systolic function (LVGLSNormal-LVEFNormal), 87 (13%) had subclinical LV dysfunction (LVGLSLow-LVEFNormal) and 66 (10%) had overt LV dysfunction (LVGLSLow-LVEFLow). Compared to the overt LV dysfunction group, the subclinical LV dysfunction group had similar 10-year transplant-free survival (64% vs 63%, p=0.6), but were less likely to be on heart failure therapy (12% vs 82%, p<0.001). LVGLS (but not LVEF) was the independent predictor of transplant-free survival
Conclusions
LVGLS provided more robust risk stratification and prognostication than LVEF in patients with Ebstein anomaly, and patients with low LVGLS had reduced transplant-free survival regardless of LVEF. The use of LVGLS (rather than LVEF) as the measure of LV systolic function has important clinical implications with regards to initiation of medical and surgical therapies.

Abstract
Abstract
Background
Left atrial dysfunction (LAD) and left ventricular diastolic dysfunction (LVDD) has been described in patients with coarctation of aorta (COA). However, it is unknown whether LA function and LV diastolic function indices can be used for prognostication in this population. The purpose of this study was to determine whether LAD and LVDD were associated with mortality in adults with COA. We hypothesized that LA and LV diastolic function indices will predict transplant-free survival in COA patients.
Methods
Retrospective study of COA patients (age ≥18) at Mayo Clinic (2000–2018). LVDD was determined using the 2016 guidelines for LVDD assessment, and LAD was assessed using LA reservoir strain.
Results
Of 721 patients, LV diastolic function could be determined in 635 (88%), while 86 (12%) were classified as indeterminate diastolic function. Of 635 patients, 414 (65%) had no LVDD, while 146 (23%), 53 (8%), and 22 (4%) had grade I/II/III LVDD respectively. The mean LA reservoir strain was −39±11%, and patients were divided into quartiles: top quartile (reference group), mild LAD, moderate LAD, and severe LAD.
Of 635 patients, 49 died and 4 underwent heart transplant. On multivariate analysis, Grade III diastolic dysfunction (but not Grade I and II) was associated with mortality as compared to normal diastolic function. On the other hand, there was an incremental risk of mortality across LA strain quartiles: mild LAD (HR 1.16, 1.04–2.06), moderate LAD (HR 1.75, 1.27–3.58), and severe LAD (HR 3.49, 1.88–7.16). Of the 86 patients with indeterminate diastolic function, LAD was associated with a lower 5-year transplant-free survival as compared to normal LA function (83% vs 91%, p=0.06).
Conclusions
LAD (but not LVDD) was associated with incremental risk of mortality, and thus can be used for prognostication in all patients including those with indeterminate diastolic function. Although the current study did not identify a consistent relationship between LVDD severity classifications and mortality among COA patients, it does not imply that LVDD is benign. Rather it suggests that the conventional criteria for LVDD severity classifications may not be generalizable to every disease subgroup

Abstract
Abstract
Background
There are limited data about outcomes after repair of native coarctation of aorta (COA) in adulthood. The purpose of this study was to describe the procedural outcomes, hemodynamic improvement, regression of LV hypertrophy and cardiovascular events in adults undergoing repair of native COA.
Methods
The primary outcomes were procedural complications, re-interventions, and hemodynamic improvement (residual COA gradient <20 mmHg) after COA repair. The secondary outcomes were improvement in the severity of hypertension, regression of left ventricular mass index (LVMI), and incidence of cardiovascular events (atrial fibrillation, heart failure hospitalization, and cardiovascular death) after COA repair. Clinical and imaging indices were assessed pre-intervention, and at 1-year (Y1) and 3-years (Y3) post-intervention.
Results
A total of 172 patients (age 38 [27–48]) underwent COA repair (surgical 161; transcatheter 11). There were no procedural deaths, and all patients had residual COA gradient <20 mmHg. One patients that received transcatheter stent therapy required re-dilation of stent at 12 months post-intervention. There as a reduction in the prevalence of patients requiring anti-hypertensive therapy from 73% (pre-intervention) to 59% and 64% at Y1 and Y3 respectively. However, 72% and 69% of the patients still had systolic blood pressure >130 mmHg (stage 1 and 2 hypertension) at Y1 and Y3 respectively. As compared to patients without hypertension at Y1, patients with stage 1 and stage 2 hypertension had less robust LVMI regression (% change in LVMI 12±5% vs 9±6% vs 5±3%, p<0.001). Hypertension (HR 1.16, 1.05–1.27) and LVMI regression (HR 0.86, 0.81–0.90) were independently associated with cardiovascular events.
Conclusions
Persistent hypertension was common after repair of native COA in adults. Hypertension (including stage 1 hypertension) was associated with suboptimal regression of LVMI and cardiovascular events. These results are concerning, and highlight the importance of early COA diagnosis and repair, and optimal medical therapy for hypertension after COA repair.

Abstract
Abstract
Background
The relationship between office vs ambulatory blood pressure (BP) indices is well-studied in patients with idiopathic hypertension, and based on these data, it is known that average 24-hour ambulatory BP is typically lower than office BP. However, emerging data show that office systolic BP (SBP) underestimates arterial afterload in patients with coarctation of aorta (COA), and minimal increase in stroke volume during low intensity exercise results in exaggerated rise in SBP as compared to those with idiopathic hypertension. We hypothesized that COA patients will have higher ambulatory SBP and a higher prevalence of masked hypertension compared to patients with idiopathic hypertension.
Methods
Case-control study of 118 COA patients and 118 patients with idiopathic hypertension matched by age, sex, body mass index and office SBP.
Results
Although both groups had similar office SBP (132±17 mmHg) by design, the COA group had paradoxical increases in 24-hour ambulatory SBP (135±14 vs 126±13, p<0.001) and daytime ambulatory SBP (142±16 vs 130±13, p<0.001), and less nocturnal dipping (−3±5 vs −9±4, p<0.001). The COA group also had a higher prevalence of masked hypertension (36 [31%] vs 14 [12%], p<0.001), and worse arterial function indices.
Conclusion
These findings underscore the potential limitations of relying on office SBP for screening/monitoring of hypertension in COA and potential pitfalls in extrapolating idiopathic hypertension guidelines recommendations to the treatment of COA. It also provides rationale for further studies to determine if pharmacologic BP interventions guided by ambulatory BP data will improve clinical outcomes in the COA population.

Abstract
BACKGROUND Cataract surgery is one of the most common surgical procedures performed worldwide. Achieving appropriate intraoperative mydriasis is one of the critical factors associated with the safety and performance of the surgery. Inadequate pupillary dilation or constriction of the pupil during cataract surgery can impair the surgeon's field of view and make it difficult to maneuver instruments. OBJECTIVES To evaluate the relative effectiveness of achieving pupillary dilation during phacoemulsification for cataract extraction using three methods of pupillary dilation: topical mydriatics, intracameral mydriatics, or depot delivery systems. We also planned to document and compare the risk of intraoperative and postoperative complications following phacoemulsification for cataract extraction, as well as the cost-effectiveness of these methods for pupillary dilation. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL), which contains the Cochrane Eyes and Vision Trials Register) (2021, Issue 1); Ovid MEDLINE; Embase.com; PubMed; Latin American and Caribbean Health Sciences Literature Database (LILACS); ClinicalTrials.gov; and the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP). We did not use any date or language restrictions in the electronic search for trials. We last searched the electronic databases on 22 January 2021. SELECTION CRITERIA We included only randomized controlled trial (RCTs) in which participants underwent phacoemulsification for cataract extraction. DATA COLLECTION AND ANALYSIS We followed standard Cochrane methodology. MAIN RESULTS We included a total of 14 RCTs (1670 eyes of 1652 participants) in this review. Of the 14 trials, 7 compared topical versus intracameral mydriatics, 6 compared topical mydriatics versus depot delivery systems, and 1 compared all three methods. We were unable to calculate overall estimates of comparative effectiveness for most outcomes due to statistical heterogeneity among the estimates from individual studies or because outcome data were available from only a single study. Furthermore, the certainty of evidence for most outcomes was low or very low, due primarily to imprecision and risk of bias. Comparison 1: topical mydriatics versus intracameral mydriatics Four RCTs (739 participants, 757 eyes) of the 8 RCTs that had compared these two methods reported mean pupillary diameters at the time surgeons had performed capsulorhexis; all favored topical mydriatics, but heterogeneity was high (I2 = 95%). After omitting 1 RCT that used a paired-eyes design, evidence from three RCTs (721 participants and eyes) suggests that mean pupil diameter at the time of capsulorhexis may be greater with topical mydriatics than with intracameral mydriatics, but the evidence is of low certainty (mean difference 1.06 mm, 95% confidence interval (CI) 0.81 mm to 1.31 mm; I2 = 49%). Four RCTs (224 participants, 242 eyes) reported mean pupillary diameter at the beginning of cataract surgery; the effect estimates from all trials favored topical mydriatics, with very low-certainty evidence. Five RCTs (799 participants, 817 eyes) reported mean pupillary diameter at the end of cataract surgery. Data for this outcome from the largest RCT (549 participants and eyes) provided evidence of a small difference in favor of intracameral mydriasis. On the other hand, 2 small RCTs (78 participants, 96 eyes) favored topical mydriatics, and the remaining 2 RCTs (172 participants) found no meaningful difference between the two methods, with very low-certainty evidence. Five RCTs (799 participants, 817 eyes) reported total intraoperative surgical time. The largest RCT (549 participants and eyes) reported decreased total intraoperative time with intracameral mydriatics, whereas 1 RCT (18 participants, 36 eyes) favored topical mydriatics, and the remaining 3 RCTs (232 participants) found no difference between the two methods, with very low-certainty evidence. Comparison 2: topical mydriatics versus depot delivery systems Of the 7 RCTs that compared these two methods, none reported mean pupillary diameter at the time surgeons performed capsulorhexis. Six RCTs (434 participants) reported mean pupillary diameter at the beginning of cataract surgery. After omitting 1 RCT suspected to be responsible for high heterogeneity (I2 = 80%), meta-analysis of the other 5 RCTs (324 participants and eyes) found no evidence of a meaningful difference between the two methods, with very low-certainty evidence. Three RCTs (210 participants) reported mean pupillary diameter at the end of cataract surgery, with high heterogeneity among effect estimates for this outcome. Estimates of mean differences and confidence intervals from these three RCTs were consistent with no difference between the two methods. A fourth RCT reported only means for this outcome, with low-certainty evidence. Two small RCTs (118 participants) reported total intraoperative time. Surgical times were lower when depot delivery was used, but the confidence interval estimated from one trial was consistent with no difference, and only mean times were reported from the other trial, with very low-certainty evidence. Comparison 3: Intracameral mydriatics versus depot delivery systems Only one RCT (60 participants) compared intracameral mydriatics versus depot delivery system. Mean pupillary diameter at the time the surgeon performed capsulorhexis, phacoemulsification time, and cost outcomes were not reported. Mean pupil diameter at the beginning and end of cataract surgery favored the depot delivery system, with very low-certainty evidence. Adverse events Evidence from one RCT (555 participants and eyes) comparing topical mydriatics versus intracameral mydriatics suggests that ocular discomfort may be greater with topical mydriatics than with intracameral mydriatics at one week (risk ratio (RR) 10.57, 95% CI 1.37 to 81.34) and one month (RR 2.51, 95% CI 1.36 to 4.65) after cataract surgery, with moderate-certainty evidence at both time points. Another RCT (30 participants) reported iris-related complications in 11 participants in the intracameral mydriatics group versus no complications in the depot delivery system group, with very low-certainty evidence. Cardiovascular related adverse events were rarely mentioned. AUTHORS' CONCLUSIONS Data from 14 completed RCTs were inadequate to establish the superiority of any of three methods to achieve mydriasis for cataract surgery, based on pupillary dilation at different times during the surgery or on time required for surgery. Only one trial had a sample size adequate to yield a robust effect estimate. Larger, well-designed trials are needed to provide robust estimates for the comparison of mydriasis approaches for beneficial and adverse effects.

Abstract
PURPOSE To characterize the epidemiology and outcomes of hyphema. METHODS Retrospective case series. Medical records from patients with traumatic and spontaneous hyphema seen at the Wilmer Eye Institute, Johns Hopkins, from 2011 through 2017 were evaluated. Aetiology, demographics, clinical characteristics, complications, management and outcomes were ascertained. Multivariable logistic regression was used to identify factors associated with elevated intraocular pressure (IOP), rebleeding and poor outcome (final visual acuity ≤ 20/40) in traumatic hyphema. A safe frequency of follow-up was retrospectively determined. RESULTS Traumatic hyphema (n = 152) was more common in males (78%) and adults (55%), with sports/recreational activities being the most frequent cause (40%). Elevated IOP was the most common complication (39%). Rebleeding occurred in seven patients (5%) and was more likely with a higher IOP on presentation (OR:1.1; p = 0.004). Thirty-seven patients (24%) had a poor outcome, mostly due to traumatic sequelae such as cataract (32%) or posterior segment involvement (30%). A poor outcome was more likely with worse presenting visual acuity (OR: 9.1; p = 0.001), rebleeding (OR: 37.5; p = 0.035) and age > 60 years (OR: 16.0; p = 0.041). Spontaneous hyphema (n = 28) did not have a gender predominance and was more common in adults > 60 years (71%). The most common cause was iris neovascularization (61%). Complications and visual outcomes were worse compared with traumatic hyphema. CONCLUSIONS Traumatic hyphema continues to be common in young males engaging in sports, necessitating increased awareness for preventive eyewear. Older age and rebleeding can lead to poor outcomes. Elevated IOP at presentation predisposes to rebleeding and warrants frequent follow-up. Otherwise, routine follow-up at days 1, 3, 5, 7 and 14 is sufficient for uncomplicated cases.

Abstract
Purpose: Falls is a leading cause of injuries nationally and can lead to serious ophthalmic injuries. The purpose of this study is to examine the incidence and characteristics of ophthalmic trauma in patients with fall-related hospitalizations in the United States.Methods: Retrospective, cross-sectional study. National Inpatient Sample (NIS) was queried to identify all ophthalmic trauma associated with fall-related hospitalizations from 2000 to 2017. Patients were identified using relevant International Classification of Diseases (ICD) codes. National estimates, annual incidences and characteristics were produced from trend weights provided by the NIS sampling frame and population data from the US Census Bureau.Results: There were 21,415,120 fall-related hospitalizations of which 425,725 (2.0%) had ophthalmic trauma. Ophthalmic injury incidence increased from 4.26 to 14.31 per 100,000 population (P < .01) from 2000 to 2017. Mean (±SEM) age was 69.2 ± 20.1 years and 56.9% were females. Of the patients with specified fall mechanism, the most common mechanisms were tripping or stumbling (48.0%), falls related to furniture (18.3%), and falls related to stairs (16.3%). The most common ophthalmic injuries were contusions of the eye and adnexa including hyphema and commotio retinae (50.1%), orbital fractures (20.7%), and eyelid lacerations (14.9%).Conclusions: Incidence of ophthalmic trauma in patients with fall-related hospitalizations has increased and our study provides valuable information for targeting preventive measures particularly for the elderly and falls due to tripping, stairs, and furniture related accidents. The most common associated ophthalmic injuries are contusions, orbital fractures and eyelid lacerations.

Abstract
Purpose: We report a unique case of blunt ocular trauma with subretinal fluid (SRF), presumed to be traumatic choroidopathy as evidenced by multimodal imaging. Methods: A case report is presented. Results: A 22-year-old woman involved in a motor vehicle accident presented 1 day later to our emergency department with blurred vision in the left eye. Visual acuity was 20/40, significant SRF was present throughout the macula, and fluorescein angiography showed diffuse pooling and leakage. There were no retinal tears or intraocular inflammation. Indocyanine green angiography performed a week later showed patchy hypofluorescence in the affected area. One month later, visual acuity had improved to 20/20 and the SRF and the hypofluorescence on indocyanine green angiography had resolved. Conclusions: Subfoveal collection of SRF may be a cause of decreased vision following blunt ocular trauma. We hypothesize that in our case choroidal hypoperfusion and retinal pigment epithelial dysfunction contributed to the SRF collection.

Abstract
Purpose To report the clinical characteristics, complications, and outcomes of hyphema in patients with sickle cell trait (SCT). Design Retrospective case series. Methods Medical records of SCT patients (confirmed by hemoglobin electrophoresis) presenting with hyphema at the Wilmer Eye Institute over 10 years (January 2008 through December 2017) were reviewed in detail. Data were collected regarding etiology, demographics, clinical course and management. Main outcome measures included intraocular pressure (IOP) and visual acuity (VA). Results A total of 14 black patients (males: 57%; median age: 20 years) were included in the study with a median follow-up of 4 months (range: 1 week to 6 years). Ten patients had traumatic hyphema with a mean presenting VA of approximately 1.10 logMAR (Snellen equivalent=20/250) and a mean presenting IOP of 40 mmHg. Nine of them required medical intervention to lower IOP, and six of them ultimately required surgical intervention, primarily in the form of anterior chamber paracentesis and/or washout. The mean time to achieve IOP control was 3 days, and the mean final VA was approximately 0.10 logMAR (Snellen Equivalent=20/25). Four patients had non-traumatic hyphema with a mean presenting VA of approximately 1.8 logMAR (Snellen equivalent=20/1260) and a mean presenting IOP of 31 mmHg. Three of them required medical intervention to lower IOP, and two of them ultimately required surgical intervention. Overall, seven patients underwent anterior chamber washout, six needed an anterior chamber paracentesis to lower the IOP, two required tube shunt placement procedures and one patient underwent a trabeculectomy. The mean time to achieve IOP control was 5 days, and the mean final VA was approximately 0.80 logMAR (Snellen equivalent=20/125). Conclusion Patients with SCT are likely to develop elevated IOP in the setting of hyphema, with a majority requiring one or more surgical interventions to achieve IOP control.

Abstract
BACKGROUNDIn retinitis pigmentosa (RP), rod photoreceptors degenerate from 1 of many mutations, after which cones are compromised by oxidative stress. N-acetylcysteine (NAC) reduces oxidative damage and increases cone function/survival in RP models. We tested the safety, tolerability, and visual function effects of oral NAC in RP patients.METHODSSubjects (n = 10 per cohort) received 600 mg (cohort 1), 1200 mg (cohort 2), or 1800 mg (cohort 3) NAC bid for 12 weeks and then tid for 12 weeks. Best-corrected visual acuity (BCVA), macular sensitivity, ellipsoid zone (EZ) width, and aqueous NAC were measured. Linear mixed-effects models were used to estimate the rates of changes during the treatment period.RESULTSThere were 9 drug-related gastrointestinal adverse events that resolved spontaneously or with dose reduction (maximum tolerated dose 1800 mg bid). During the 24-week treatment period, mean BCVA significantly improved at 0.4 (95% CI: 0.2-0.6, P < 0.001), 0.5 (95% CI: 0.3-0.7, P < 0.001), and 0.2 (95% CI: 0.02-0.4, P = 0.03) letters/month in cohorts 1, 2, and 3, respectively. There was no significant improvement in mean sensitivity over time in cohorts 1 and 2, but there was in cohort 3 (0.15 dB/month, 95% CI: 0.04-0.26). There was no significant change in mean EZ width in any cohort.CONCLUSIONOral NAC is safe and well tolerated in patients with moderately advanced RP and may improve suboptimally functioning macular cones. A randomized, placebo-controlled trial is needed to determine if oral NAC can provide long-term stabilization and/or improvement in visual function in patients with RP.TRIAL REGISTRATIONNCT03063021.FUNDINGMr. and Mrs. Robert Wallace, Mr. and Mrs. Jonathan Wallace, Rami and Eitan Armon, Marc Sumerlin, Cassandra Hanley, and Nacuity Pharmaceuticals, Inc.

Abstract
PURPOSE To examine the incidence, characteristics, and economic burden of orbital floor fractures in the United States. DESIGN Retrospective, longitudinal study of the Nationwide Emergency Department Sample (NEDS). PARTICIPANTS Patients in the Emergency Department (ED). METHODS The NEDS, a representative sample of all hospital-based EDs in the US, was used to identify and describe ED visits with a primary diagnosis of orbital floor fracture from 2006 to 2017. Linear regression was used to estimate the trends in annual incidence and inflation-adjusted ED charges. Logistic regression was used to assess variables associated with inpatient admission. MAIN OUTCOME MEASURES Incidence, injury mechanisms, demographics, clinical characteristics, disposition, and economic burden. RESULTS From 2006 to 2017, there were an estimated 350 379 ED visits in the US with a primary diagnosis of orbital floor fracture. The incidence increased by 47% over the study period (P < 0.001): from 7.7 (95% confidence interval [CI], 6.9-8.5) to 11.3 (95% CI, 10.0-12.6) per 100 000 population. The majority were male (67%), aged 21 to 44 years (46%), and from low-income households (32%). The most common cause was assault (43%), which was most frequent in young adults (65%) and increased modestly over time (3.5 to 4.5 per 100 000 population; P = 0.02). The second most common cause was falls (26%), most frequent in patients aged ≥65 years (86%) and more than doubled over time (1.6 to 3.5 per 100 000 population; P < 0.001). The rate of inpatient admission was 14%, with a higher likelihood for patients aged ≥65 years (odds ratio [OR], 2.21; 95% CI, 1.99-2.46; P < 0.001) and falls (OR, 1.54; 95% CI, 1.27-1.86; P < 0.001). The total inflation-adjusted ED charges over the study period exceeded $2 billion, with the mean charge per visit increasing 48% (P < 0.001): from $5881 (95% CI, 5499-6263) to $8728 (95% CI, 8074-9382). CONCLUSIONS Orbital floor fractures are becoming an increasingly common and costly injury in the United States. Preventive strategies aimed at reducing assault and falls will be crucial to mitigate the burden of orbital floor fractures on the healthcare system.

Abstract
BACKGROUND The retinal vasculature may be altered in multiple sclerosis (MS), potentially acting as a biomarker of disease processes. OBJECTIVE To compare retinal vascular plexus densities in people with MS (PwMS) and healthy controls (HCs), and examine correlations with visual function and global disability. METHODS In this cross-sectional study, 111 PwMS (201 eyes) and 50 HCs (97 eyes) underwent optical coherence tomography angiography (OCTA). Macular superficial vascular plexus (SVP) and deep vascular plexus (DVP) densities were quantified, and poor quality images were excluded according to an artifact-rating protocol. RESULTS Mean SVP density was 24.1% (SD = 5.5) in MS eyes (26.0% (SD = 4.7) in non-optic neuritis (ON) eyes vs. 21.7% (SD = 5.5) in ON eyes, p < 0.001), as compared to 29.2% (SD = 3.3) in HC eyes (p < 0.001 for all MS eyes and multiple sclerosis optic neuritis (MSON) eyes vs. HC eyes, p = 0.03 for MS non-ON eyes vs. HC eyes). DVP density did not differ between groups. In PwMS, lower SVP density was associated with higher levels of disability (expanded disability status scale (EDSS): R2 = 0.26, p = 0.004; multiple sclerosis functional composite (MSFC): R2 = 0.27, p = 0.03) and lower letter acuity scores (100% contrast: R2 = 0.29; 2.5% contrast: R2 = 0.40; 1.25% contrast: R2 = 0.31; p < 0.001 for all). CONCLUSIONS Retinal SVP density measured by OCTA is reduced across MS eyes, and correlates with visual function, EDSS, and MSFC scores.

Abstract
AimsTo characterise the epidemiology of eye trauma in the event of falls presenting to the emergency departments (ED) in the USA.MethodRetrospective cohort study. Nationwide Emergency Department Sample was used to analyse fall encounters presenting to the ED with eye trauma from 2006 to 2015. National estimates of the leading diagnoses were determined, and multivariable regression was used to determine the relationship between factors involved in fall encounters presenting with eye trauma.ResultsFrom 2006 to 2015, an estimated 87 991 036 fall encounters presented to the ED, of which 952 781 encounters had eye trauma as either a primary or secondary diagnosis. The overall incidence of fall encounters with eye trauma per 100 000 US population increased from 30.7 encounters in 2006 to 33.8 encounters per 100 000 population in 2014 with a decrease seen in 2015. Eye trauma, including vision-threatening type, was highest in females (n=500 520, 52.5%), elderly (n=400 209, 42%) and children (n=2 06 741, 21.7%). Elderly were more likely to have eye trauma in the setting of falls (adjusted OR (aOR) 2.06, 95% CI 2.02 to 2.11) and be admitted (aOR 1.89, 95% CI 1.86 to 1.91) than adults (reference). The leading types of eye trauma were contusion of orbital tissues (n=174 292, 18.3%), laceration of eyelid and periocular area (n=172 361, 18.1%) and orbital fractures (n=151 013, 15.8%).ConclusionsFalls are preventable, yet the incidence of falls and resulting eye trauma are increasing despite our best efforts. As ophthalmologists, we should not only develop guidelines to recognise and counsel at-risk groups under our care but also strategies for prevention of eye trauma secondary to falls.

Abstract
PURPOSE To describe the epidemiology of Emergency Department (ED) visits related to opioid abuse with primary ophthalmic diagnoses in the United States (US). METHODS This retrospective cross-sectional study used National ED Sample (NEDS) (2006-2015), a representative sample of all US EDs, to analyze and compare the epidemiology of primary ophthalmic diagnoses in opioid abusers and a control group of non-opioid users. National incidence and descriptive statistics were calculated for demographics and prevalent diagnoses. Multivariable logistic regression was used to compare outcomes between primary ophthalmic diagnoses in opioid and non-opioid abusers. RESULTS An estimated 10,617 visits had a primary ophthalmic diagnosis and an accompanying opioid abuse diagnosis, and the incidence increased from 0.2 in 2006 to 0.6 per 100,000 US population in 2015. Opioid abuse group had more adults (6,747:63.5%) and middle-aged (3,361:31.7%) patients, while in controls adults (7,905,003:40.4%) and children (4,068,534:20.8%) were affected more. Leading etiologies were similar: traumatic and infectious etiologies were most common; however, opioid abuse patients had more severe ophthalmic diagnoses such as orbital fractures (8.4%), orbital cellulitis (7.4%), globe injury (3.4%) and endophthalmitis (3.2%) compared to controls. Patients in the opioid abuse group were also more likely to be admitted (adjusted Odds Ratio [aOR], 28.38 [95% CI, 24.50-32.87]). CONCLUSIONS In the era of opioid crisis, an increase in ED visits with ophthalmic complaints is seen, with increasing direct and indirect costs on the healthcare system. More research is needed to establish causality and devise strategies to lower this burden.

Abstract
Importance Eye trauma is a common cause of vision loss and a substantial public health problem. Objective To determine the changes in the incidence of eye trauma hospitalizations in the United States and compare the demographics of affected patients and outcomes of eye trauma as a primary or secondary admitting diagnosis. Design, Setting, and Participants This retrospective longitudinal cohort study used the National Inpatient Sample, a representative sample of all US community hospitals, to determine the incidence, characteristics, and causes of primary and secondary inpatient eye trauma admissions from 2001 through 2014. All inpatients with relevant diagnoses were included. Linear regression was used to estimate changes in incidence. Logistic regression was used to compare demographics and outcomes between primary and secondary diagnoses, including age, sex, race, income, primary payer, region, year of admission, length of stay, cost, and disposition at discharge. Exposures Eye trauma. Main Outcomes and Measures Incidence and characteristics of inpatient primary and secondary eye trauma. Results From 2001 to 2014, there were an estimated 939 608 inpatient admissions (of whom 556 886 were male patients [59.3%]; overall mean [SD] age, 49.4 [25.2] years) in the United States because of eye trauma diagnoses, with 778 967 of these (82.9%) as a secondary diagnosis. The incidence of primary eye trauma decreased from 3.9 to 3.0 per 100 000 population (difference, 0.9 [95% CI, 0.2-1.6] per 100 000 population; P = .001). The incidence of eye trauma as a secondary admitting diagnosis increased from 14.5 to 19.0 per 100 000 population (difference, 4.5 [95% CI, 1.9-7.2] per 100 000 population; P = .004). This was largely attributed to an increasing number of falls in individuals older than 65 years. The most frequent diagnosis was orbital fracture (64 149 [39.9%]) for primary trauma and contusion of eye and adnexa (19 301 [37.8%]) for secondary trauma. Primary trauma was more common in children (adjusted odds ratio [aOR], 2.21 [95% CI, 2.09-2.32]) and adolescents (aOR, 1.25 [95% CI, 1.19-1.32]) than adults (reference), African American individuals (aOR, 1.89 [95% CI, 1.81-1.97]) and Hispanic individuals (aOR, 1.52 [95% CI, 1.45-1.59]) than white individuals, and uninsured patients (aOR, 1.14 [95% CI, 1.07-1.22]) and those receiving Medicaid (aOR, 1.12 [95% CI, 1.05-1.19]) than Medicare beneficiaries. Patients with a primary diagnosis were more likely to have a stay of less than 3 days (patients with a primary diagnosis: 101 796 [63.4%]; secondary diagnosis: 274 538 [35.2%]), more likely to have costs in the lowest quartile (patients with a primary diagnosis: 51 212 [31.9%]; secondary diagnosis: 166 260 [21.3%]), and less likely to die (patients with a primary diagnosis: 526 [0.3%]; secondary diagnosis: 20 929 [2.7%]). Conclusions and Relevance These findings suggest that the increasing number of falls in individuals older than 65 years and the high risk of primary eye trauma in populations such as children and adolescents warrant the development and implementation of effective preventive strategies. Many of these patients are seen in ophthalmology practices where proactive risk assessment and counseling can play a critical role.

Abstract
PURPOSE To determine the trends and disparities in inpatient costs for eye trauma in the United States from 2001 through 2014. DESIGN Retrospective population-based cross-sectional study. METHODS National Inpatient Sample, a representative sample of U.S. hospital discharges, was used to determine costs of eye trauma hospitalizations. Linear regression was used to estimate changes in mean inflation-adjusted cost per admission. Multivariable logistic regression was used to evaluate factors associated with a cost in the highest quartile (>$13 000) including age, sex, race, income quartile, primary payer, hospital location, size, and type. The model was adjusted for year of admission, length of stay, type of trauma, comorbidities, and the type and number of procedures performed. RESULTS The inpatient costs for eye trauma from 2001 through 2014 totaled $1.72 billion. The mean cost (95% confidence interval [CI]) per stay remained relatively constant: $12 000 ($11 000-13 000) in 2001 to $11 000 ($10 000-12 000) in 2014 (P = .643). A cost in the highest quartile was more likely in African Americans compared to whites (adjusted odds ratio, 1.3; 95% CI, 1.2-1.5), patients in the highest income quartile compared to those in the lowest (1.3; 1.2-1.5), uninsured patients compared to publicly insured patients (1.2; 1.1-1.4), teaching hospitals compared to non-teaching ones (1.5; 1.2-1.8), and the West compared to the South (2.4; 2.0-2.8). CONCLUSIONS Inpatient costs of eye trauma have remained steady and can be potentially reduced by addressing associated disparities. Further research including outpatient costs and eye trauma in vulnerable populations will be key to optimizing care and advancing healthcare equity.

Abstract
PURPOSE To evaluate long-term visual and anatomic outcomes in patients with retinal vein occlusion (RVO) treated with anti-vascular endothelial growth factor (VEGF) agents. DESIGN Prospective, interventional case series. PARTICIPANTS Patients with central RVO (CRVO) or branch RVO (BRVO). METHODS Number of anti-VEGF injections and improvement from baseline best-corrected visual acuity (BCVA) and central subfield thickness (CST) were prospectively recorded in 40 eyes of 39 CRVO patients and 50 eyes of 47 BRVO patients. RESULTS Mean follow-up was 58 months for BRVO and 78 months for CRVO. Within 6 months of last follow-up, 58% of BRVO patients and 75% of CRVO patients required anti-VEGF injections to control edema. Analysis of the course of each patient over time showed that for BRVO patients, BCVA letter score increased by a mean of 24, from baseline of 52 (20/100) to peak of 76 (20/32), and subsequently decreased by 13, to 63 (20/50), at final visit; and for CRVO patients, BCVA letter score increased by a mean of 26, from baseline of 48 (20/100) to peak of 74 (20/32), and subsequently decreased by 18, to 56 (20/80), at last follow-up. Loss from peak BCVA occurred primarily owing to persistent/recurrent edema and related foveal damage. CONCLUSIONS Patients with RVO showed large improvements in BCVA after initiation of anti-VEGF injections, but in many patients some visual gains were lost over time owing to bouts of recurrent edema. Sustained suppression of VEGF may help to provide optimal outcomes in RVO and reduce treatment burden.

Abstract
Introduction Multiple myeloma (MM) is a common hematologic malignancy with variable degrees of immunodeficiency. Disease- and treatment-related compromise of the immune system predisposes patients to infections, which are a major cause of morbidity and mortality. Objective We aimed to establish the incidence and main characteristics of infections in MM patients treated at our center over a 10-year period. Method and results Of the 412 patients retrospectively analyzed, 154 (37.4%) were documented to have at least one episode of infection and were included in this study. A total of 244 infectious episodes were documented. The most common site of infection was the lung, followed by the genitourinary system. The most common infections were bacterial, followed by viral. Escherichia coli were the most common organism. In 160 (65.5%) episodes, the organism was not isolated. Thalidomide with dexamethasone was the most common treatment regimen, followed by melphalan with dexamethasone. Infection was the main cause of death in 26 (6.3%) out of all 412 patients. Conclusion Infections are a notable cause of morbidity and mortality in the clinical course of MM patients. By considering patient and disease characteristics, a risk-adapted selection of the MM treatment should be employed, with special attention toward patient age and disease-associated organ dysfunction. Patient education, access to healthcare and physician vigilance are also essential. Vaccination and antimicrobial prophylaxis may be considered prior to or during therapy.

Abstract
AIM To develop a simple and easily applicable classification of disease severity in retinitis pigmentosa (RP). METHODS This is a retrospective cross-sectional study. Visual acuity (VA), visual field width (VF) and ellipsoid zone width (EZ) were obtained from medical records of patients with RP. A scoring criterion was developed wherein each variable was assigned a score from 0 to 5 depending on its distribution. The cumulative score (from 0 to 15) was used to classify disease severity from grade 0 to 5. The scores were correlated with each other and the final grade. The grades were then correlated with age and disease duration. RESULTS The median age (range) of patients (n=93) was 55 (12-87) years, 51% were female, 70% had been diagnosed within 10 years, and 50% had autosomal recessive disease. Most eyes (n=181) at least had a VA of 20/40 (67%), a VF of 20° (75%) and an EZ of 5° (76%). All scores were correlated with each other (r=0.509-0.613; p<0.001 for all) and with the final grade (r=0.790-0.869; p<0.001 for all). Except for grade 0 (5%), all grades were evenly distributed: 21% for grade 1, 23% for grade 2, 22% for grade 3, 17% for grade 4 and 12% for grade 5. Grades were correlated with both age (r=0.252; p<0.001) and disease duration (r=0.383; p<0.001). CONCLUSIONS We present a simple, objective and easy to use disease severity classification for RP which can be used to categorise and compare patients.

Abstract
PURPOSE To evaluate artifacts in optical coherence tomography angiography (OCT-A) images of multiple sclerosis (MS) patients and healthy controls. MATERIALS AND METHODS This was a prospective cross-sectional study conducted at the Department of Neurology and the Wilmer Eye Institute at Johns Hopkins Hospital. Subjects included patients with an established diagnosis of MS and healthy volunteers. OCT-A was performed using Spectralis® OCT-A prototype, OCT2 (Heidelberg, Germany). The type and frequency of artifacts, the clinical factors associated with them, and their impact on vessel density measurements were assessed. RESULTS Overall, 385 images from 102 participants were analyzed. The majority of images (97.1%) had some degree of artifact. The most frequent was motion artifact (96.3%), followed by blinking (51.9%), and loss of focus (25.1%). MS patients were more likely to have any artifact vs. controls (OR [95% CI], 3.83 [1.12-12.92]), and were more likely to have motion artifacts with longer disease duration (OR [95% CI], 1.11 [1.03-1.20]) or history of optic neuritis (OR [95% CI], 4.24 [1.19-15.16]). The relative area occupied by the artifact was found to underestimate vessel density measurements in both MS patients and controls. CONCLUSIONS Artifacts are common with OCT-A imaging using this particular Spectralis® OCT-A prototype and can impact quantitative vascular density metrics. Future studies should review images for artifacts before drawing definitive conclusions.

Abstract
PURPOSE To determine the national estimates, demographics, and costs of inpatient eye care in the United States (US). DESIGN Retrospective cross-sectional study. METHODS National Inpatient Sample (NIS), a representative sample of all US community hospitals, was used to analyze inpatient admissions with a primary ophthalmic diagnosis from 2001 to 2014. National estimates of the most prevalent diagnoses were determined, and descriptive statistics were calculated for demographics and costs. RESULTS From 2001 to 2014, there were an estimated 671 324 inpatient admissions (male patients, 51.6%; mean [standard deviation] age, 44.5 [27.3] years) in the US owing to an ophthalmic disorder-an annual rate of 16 per 100 000 population. The Mid-Atlantic region had the highest rate. Most admissions were owing to nontraumatic disorders (75.3%), classified as emergencies (41.8%), and covered by public insurance (48.9%). The median length of stay was 2 days and mortality was 0.2%. The total inflation-adjusted cost over the 14-year period was $5.9 billion. The most prevalent diagnosis was orbital cellulitis (14.5%), followed by orbital floor fracture (9.6%) and eyelid abscess (6.0%). Most diagnoses were infectious (28.0%) and the majority were attributed to external disease (24.3%). A total of 31.1% of all patients had an ophthalmic procedure, pars plana vitrectomy (4.8%) being the most common one. CONCLUSION There were around 48 000 ophthalmic inpatient admissions in the US costing $421 million every year. Orbital pathology, namely infection and trauma, was the leading cause of admissions. Implementing interventions to decrease the incidence of these conditions may significantly reduce the burden of inpatient ophthalmic care.

Abstract
PURPOSE To evaluate yearly progression of retinitis pigmentosa (RP) using microperimetry (MP) performed on Nidek MP1 (NAVIS Software v1.7; Nidek Technologies, Padova, Italy). DESIGN Retrospective longitudinal study. PARTICIPANTS RP patients with consecutive MP tests (using the same test settings). METHODS Data were collected as part of the Photoreceptor Cell Death in Retinitis Pigmentosa Retrospective (PREP-1) study. Visual acuity, fixation stability, mean sensitivity, and regional sensitivity were assessed at baseline and at yearly follow-up appointments. Regional sensitivity was calculated based on 2 methods. Method 1 involved topographical division into central macula (CM) and paracentral macula (PM). Method 2 involved functional division into the edge of scotoma (ES) and the seeing retina (SR). Linear mixed-effects models were used to assess the annual rate of change for each parameter, adjusted for disease duration. MAIN OUTCOME MEASURES Annual rate of change of visual acuity, fixation stability, and retinal sensitivities (mean sensitivity and regional sensitivities using methods 1 and 2). RESULTS In total, 75 eyes of 39 patients (median age, 56 y; males, 57%) with a follow-up period ranging from 1 to 4 years were reviewed. Visual acuity at baseline was positively correlated with all retinal sensitivity parameters, most strongly with CM sensitivity (r = 0.545, P < 0.001). There was no change in visual acuity (P = 0.075) or fixation stability (P = 0.371) per year. All retinal sensitivity parameters had a significant decline per year (P < 0.001), with a decline of 0.4 decibel (dB) for mean sensitivity, 0.6 dB for CM, 0.3 dB for PM, 1.3 dB for ES, and 1.1 dB for SR. Method 2 identified the greatest number of cases, with a significant decline in regional sensitivity. CONCLUSION MP can detect significant changes in regional sensitivity over a 1-year period in patients with RP, even as visual acuity and fixation remain stable. An individualized approach to analyzing retinal sensitivity derived from MP may offer a useful outcome measure for future clinical trials.

Abstract
OBJECTIVE To gauge the general population's knowledge and attitude towards a possible public health insurance scheme. METHODS This descriptive, cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, from April to May 2015, and comprised permanent residents of the city. Convenience sampling was used. Data was collected via questionnaires. SPSS 22 was used for data analysis. RESULTS There were 340 participants in the study with an overall mean age of 32.9±12.4 years. Besides, 159(46.8%) participants were aware of the concept of medical insurance while the correct definition was identified by 160(50.5%) respondents. Overall, 256(75.3%) participants were willing to join a theoretical public health insurance scheme. Of all the respondents, 107(31.5%) had faced a catastrophic event in the past and consequently were more willing to join. Of those unsure or not willing to join, 33(37.9%) respondents identified lack of trust in government programmes as the main reason for their choice. CONCLUSIONS A large majority of adults had a favourable attitude towards the implementation of a possible public health insurance scheme.

Abstract
AIM To discuss an unusual and rare complication of perforated caecal volvulus (CV) following open anterior resection. METHODS A retrospective review of the case notes of a patient. RESULTS CV is a well known but rare cause of bowel obstruction. Chronic constipation, distal colonic obstruction and post-operative ileus are potentially aggravating factors for the development of CV in anatomically susceptible patients. The anatomical susceptibility for CV was noticed during the first operation but prophylactic caecopexy was not performed due to lack of evidence in the literature. This patient developed CV after anterior resection and subsequently underwent a second laparotmy for right hemicolectomy. CONCLUSION CV is a known but rare case of postoperative bowel obstruction. The role of prophylactic caecopexy could be discussed in order to avoid the development of postoperative CV in anatomically susceptible patients.

Abstract
OBJECTIVE The objective of this study was to evaluate the effectiveness of the internet as a source of information for colorectal cancer (CRC). METHOD Six of the most common search engines (Yahoo, Google, MSN search, Alta Vista, Excite and Lycos) were used for the search of the generic term 'CRC'. First 300 links were analysed and classified by information type, provider, readership and commercial orientation. RESULTS The average time delay was 1.70 s before matches were located. A total of 3.2827 million matches on CRC were found using the six search engines ranging from 700 (Excite) to 1 417 000 (Lycos) websites. Approximately 50% of the links were based on information from textbooks or governmental websites. Commercial companies giving information about private hospitals and products provided over 50% of the websites on CRC. The distribution of target readers was uneven, although a majority of websites were delivering CRC information to public and patients. Readability of information was difficult to comprehend by the public. CONCLUSION The internet is becoming an essential tool for disseminating information about CRC to consumers. Half of the links on CRC are commercially oriented, containing information on goods or private health services. Less than 1% information is being provided by professional societies. To provide relevant CRC information, key consensus criteria for evaluating healthcare-related websites have to be established. There is an urgent need for CRC information on the internet to be regulated through the establishment of government-funded organizations (e.g. NHS) or professional societies (e.g. ACPGBI).

Abstract
Abnormal lipid metabolism is a main cause of dyslipidemia, which is a major risk factor for coronary heart disease and obesity and is even linked to diabetic-dyslipidemic complications. Fifteen days of high-fat feeding in Charles Foster rats resulted in a significant increase in baseline serum lipid levels accompanied by pronounced dyslipidemia. Treatment with fish liver preparations (FLPs) from sea bass and the standard drug gemfibrozil produced a lowering of serum lipids and glucose levels, along with a fall in very-low-density and low-density lipoprotein and an increase in high-density lipoprotein levels. Simultaneously, reactivation of plasma postheparin lipolytic activity (PHLA) and lecithin:cholesterol acyltransferase (LCAT) activity was also observed. A positive correlation was observed between low-density lipoprotein activity and fecal bile acid excretion, which was enhanced on treatment with FLPs and gemfibrozil, indicating the catabolic process for normal lipids and cholesterol homeostasis. These data suggest that FLPs and gemfibrozil not only lower lipid intolerance but also reduce diabetic-dyslipidemic complications by activating peroxisome proliferator-activated receptors (PPAR).

Abstract
All meconium aspiration syndrome cases admitted in the two neonatal units were compared to evaluate the antenatal and natal events including resuscitative measures and outcome of neonates and to confirm the beneficial effects of immediate combined obstetric and paediatric intervention on morbidity and mortality. Neonates managed in nursery at Mayo Hospital (Group 1, n = 44) were delivered at other hospitals and birth centres, underwent resuscitation by obstetricians and/or anaesthetists and then referred. Neonates admitted in the neonatal unit of Lady Willingdon Hospital (Group 2, n = 48) were inborn and resuscitated by paediatric residents. Both groups were comparable for weight, sex, booked status, maturity, history of prolonged labour, fetal distress and Apgar score at 5 minutes. Significant differences were proportion of C-section (62% in Gp 2 v 34% in Gp1), laryngoscopy and tracheal intubation (100% in Gp 2 v 9% in Gp1), time of arrival in the nursery (mean 0.14 hr in Gp 2 v 3.91 hr in Gp 1), persistent cyanosis (43% in Gp 2 v 68% in Gp1), earlier start of feeding (mean 2.4 days in Gp 2 v 3.2 days in group 1) and shorter stay in hospital (2.87 days in Gp 2 v 5 days in Gp 1). 27% cases died in group 2 compared to 47% in group 1 (pvalue = 0.04). Combined immediate obstetric intervention (C-section) and paediatric intervention (laryngoscopy, tracheal intubation, suction, immediate transfer to nursery) led to reduced severity of meconium aspiration syndrome and lower mortality.

Abstract
A case of autoimmune oophoritis is reported. A 41-year-old woman had a total abdominal hysterectomy and bilateral salpingo-oophorectomy for menorrhagia, polymenorrhoea and cystic ovaries. The diagnosis of autoimmune oophoritis was not suspected clinically, and was an unexpected histological finding in the ovaries. The gross and histological appearances of this rare condition are described, and the lymphoid infiltrate characterised by immunocytochemistry. Recognition of this condition by pathologists is important, as there is an associated risk of developing other autoimmune disease, even some years later, necessitating close patient follow-up. In this case serum auto-antibodies to adrenal cortex were detected, indicating a subsequent risk of Addison's disease.

Abstract
The purpose of this study was to identify the influence of hypotension as a result of epidural anesthesia and of its treatment with either ephedrine or methoxamine on uteroplacental and umbilical flow velocity ratios and fetal acid-base status. Fifty healthy women with an uncomplicated full-term pregnancy were studied during elective cesarean section under epidural anesthesia. A method of continuously recording flow velocity waveforms was used that allowed the identification of simultaneous values of maternal and fetal Doppler indices related to events during the induction of anesthesia. In 15 patients in whom arterial blood pressure did not decrease, the uteroplacental pulsatility index (UtPI) did not change, but the umbilical pulsatility index (UmPI) decreased from a mean (95% confidence interval) of 0.98 (0.88-1.09) to 0.91 (0.82-0.99) (P less than 0.05). In 32 patients who experienced hypotension of at least 15%, the UtPI increased from 0.82 (0.76-0.89) to 1.04 (0.92-1.17) (P less than 0.01). Treatment with ephedrine had no influence on either the UtPI or UmPI, but treatment with methoxamine resulted in brief increases in the UtPI of 0.47 (0.24-0.69) during the first 5 min after its administration; the increases were brief and resolved within 2 min. The choice of vasopressor drug had no influence on the UtPI recorded just before surgery commenced (final UtPI), but those patients who experienced hypotension had significantly larger final UtPIs (1.02 (0.91-1.10)) than those who never became hypotensive (0.86 (0.72-0.99)), and this was associated with significantly increased placental hydrogen ion gradients. The choice of vasopressor drug appears to be of minor importance compared with the avoidance of hypotension.
