RESUMO
PURPOSE: To evaluate risk factors for intraocular pressure (IOP) spike after cataract surgery using the IRIS® Registry (Intelligent Research in Sight). DESIGN: Retrospective clinical cohort study. PARTICIPANTS: Adults with IRIS Registry data who underwent stand-alone phacoemulsification from January 1, 2013, through September 30, 2019. METHODS: Intraocular pressure spike was defined as postoperative IOP of > 30 mmHg and > 10 mmHg from the baseline within the first postoperative week. Odds ratios (ORs) for demographic and clinical characteristics were calculated with univariable and multivariable logistic regression analyses. MAIN OUTCOME MEASURES: Incidence and OR of IOP spike. RESULTS: We analyzed data from 1 191 034 eyes (patient mean age, 71.3 years; 61.2% female sex; and 24.8% with glaucoma). An IOP spike occurred in 3.7% of all eyes, 5.2% of eyes with glaucoma, and 3.2% of eyes without glaucoma (P < 0.0001). Multivariable analyses of all eyes indicated a greater risk of IOP spike with higher baseline IOP (OR, 1.57 per 3 mmHg), male sex (OR, 1.79), glaucoma (OR, 1.20), Black race (OR, 1.39 vs. Asian and 1.21 vs. Hispanic), older age (OR, 1.07 per 10 years), and complex surgery coding (OR, 1.22; all P < 0.0001). Diabetes (OR, 0.90) and aphakia after surgery (OR, 0.60) seemed to be protective against IOP spike (both P < 0.0001). Compared with glaucoma suspects, ocular hypertension (OR, 1.55), pigmentary glaucoma (OR, 1.56), and pseudoexfoliative glaucoma (OR, 1.52) showed a greater risk of IOP spike and normal-tension glaucoma (OR, 0.55), suspected primary angle closure (PAC; OR, 0.67), and PAC glaucoma (OR, 0.81) showed less risk (all P < 0.0001). Using more baseline glaucoma medications was associated with IOP spike (OR, 1.18 per medication), whereas topical ß-blocker use (OR, 0.68) was protective (both P < 0.0001). CONCLUSIONS: Higher baseline IOP, male sex, glaucoma, Black race, older age, and complex cataract coding were associated with early postoperative IOP spike, whereas diabetes and postoperative aphakia were protective against a spike after stand-alone phacoemulsification. Glaucomatous eyes demonstrated different risk profiles dependent on glaucoma subtype. The findings may help surgeons to stratify and mitigate the risk of IOP spike after cataract surgery.

PURPOSE: Inferior vena cava (IVC) diameter and variation are commonly measured in the supine position to estimate intravascular volume status of critically ill patients. Many scientific societies describe the measurement of IVC diameter in the supine position. However, critically ill patients are rarely placed supine due to concerns for aspiration risk, worsened respiratory mechanics, increases in intracranial pressure, and the time it takes to change patient position. We assessed the influence of head-of-bed (HOB) elevation on IVC measurements. METHODS: We conducted a prospective observational study of critically ill patients undergoing critical care ultrasound. With HOB at 0°, IVC maximum (IVCmax0°) and minimum (IVCmin0°) diameters were measured. Measurements were then repeated with HOB elevated to 30° and 45°. Collapsibility index (CI), defined as (IVCmax - IVCmin)/IVCmax, was calculated for each HOB elevation. Mean differences were then compared. RESULTS: A convenience sample of 95 patients was studied, of whom 45% were on vasopressors and 44% were spontaneously breathing. The CI did not significantly differ between the three positions. We found a significant difference (P ≤ .0001) between IVCmax at 45° (2.09 cm) and 0° (1.96 cm), IVCmin at 45° (1.75 cm) and 0° (1.59 cm), IVCmax at 45° (2.09 cm) and 30° (1.97 cm), and IVCmin at 45° (1.75 cm) and 30° (1.61 cm). CONCLUSIONS: In a population of critically ill patients undergoing goal-directed ultrasound examinations, elevating HOB to 30° did not significantly alter IVC measurements or CI. At 45°, however, IVCmax and IVCmin diameters increased significantly, albeit with no significant change in CI. Performing ultrasound measurements of the IVC with HOB elevated to 30° is unlikely to produce clinically meaningful changes.

PURPOSE: To compare the presentation and outcomes of patients younger than 50 years versus patients aged 50 years and older with central retinal vein occlusion (CRVO). METHODS: This single-center retrospective study included patients with CRVO presenting between January 2009 and July 2016. Charts were reviewed and data were abstracted. Presenting and final clinical parameters, treatment burden, and predisposing factors for CRVO were compared between the two groups. RESULTS: Thirty-six patients younger than 50 years and 233 patients aged 50 years and older at the time of CRVO onset were included. At presentation, younger patients had better visual acuity than older patients (20/80 vs. 20/224, P = 0.001) and a lower incidence of cystoid macular edema (54 vs. 79%, P = 0.001). Twenty-one of 36 (58%) younger patients had at least one identifiable nontraditional risk factor for CRVO. At final follow-up, younger patients received fewer total intravitreal injections (3.8 ± 5.8 at 34.2 months) compared with older patients (6.5 ± 8.8, at 37.6 months, P = 0.03) and had better final acuity (20/85 vs. 20/289, P = 0.004, respectively). CONCLUSION: Younger patients had better baseline and final acuities, a lower incidence of cystoid macular edema at presentation, and received fewer intravitreal injections than older patients. Workup for etiology of CRVO in younger patients may reveal nontraditional risk factors for CRVO.

PURPOSE: To evaluate the association between cystoid macular edema (CME) observed in very preterm infants and developmental outcomes at 18 to 24 months corrected age. DESIGN: Cohort study. PARTICIPANTS: Infants born at or less than 1500 g or at or less than 30 weeks postmenstrual age who underwent screening for retinopathy of prematurity (ROP) in an intensive care nursery. METHODS: Bedside handheld spectral-domain optical coherence tomography (SD OCT; Envisu, Bioptigen, Inc, Research Triangle Park, NC) imaging was obtained from preterm infants who were being screened for ROP and graded for presence of CME, central foveal thickness (CFT), inner nuclear layer thickness, and foveal-to-parafoveal thickness ratio. At 18 to 24 months corrected age, the children were assessed with the Bayley Scales of Infant and Toddler Development, Third Edition. MAIN OUTCOME MEASURES: Scores on the Bayley cognitive, language, and motor subscales. RESULTS: Among 77 children with SD OCT imaging, 53 were evaluated with the Bayley Scales. Compared with children who did not have CME as infants (n=22), the mean score for children who had CME (n=31) was 7.3 points (95% confidence interval [CI], -15.5 to 0.9; P=0.08) lower on the cognitive subscale, 14.1 points (95% CI, -22.7 to -5.5; P=0.002) lower for the language subscale, and 11.5 points (95% CI, -21.6 to -1.3; P=0.03) lower for the motor subscale. Differences were maintained after adjusting for gestational age and birth weight. Severity of CME, as assessed by foveal-to-parafoveal thickness ratio, within the CME group correlated with poorer cognitive (R2=0.16, P=0.03) and motor (R2=0.15, P=0.03) development. CONCLUSIONS: Cystoid macular edema observed on SD OCT in very preterm infants screened for ROP is associated with poorer language and motor skills at 18 to 24 months corrected age. Evaluation of the retina with SD-OCT may serve as an indicator of neurodevelopmental health for very preterm infants in the intensive care nursery.

PURPOSE: The authors relate posterior segment microanatomy from perinatal spectral domain optical coherence tomography to visual acuity, brain abnormalities, and neurodevelopment. METHODS: Thirteen infants (11 preterm and 2 term birth), imaged in the nursery with portable spectral domain optical coherence tomography, had visual acuity and sensorimotor testing at age 9 months to 15 months (grating acuity) or 4 years to 5 years (optotype), and medical records reviewed for brain magnetic resonance imaging reports and Bayley scales testing at age 18 months to 24 months. RESULTS: Eight children with age-appropriate macular microanatomy without edema on perinatal spectral domain optical coherence tomography had optimal (≥ 20/40) or within normal limits (grating acuity) visual acuity. Five children with perinatal macular edema had suboptimal visual acuity (in 9/10 eyes) and sensorimotor deficits, magnetic resonance imaging abnormalities, or poor neurodevelopment. Macular edema persisted in 1 infant through 9-month corrected age. CONCLUSION: Maturation of the visual system and evolution of retinal anomalies can be monitored with posterior segment spectral domain optical coherence tomography. Retinal microanatomy observed in infancy might relate to subsequent vision and other central nervous system events, but additional studies are needed to determine the range of normal microanatomy in infants and how this relates to vision and neurodevelopment.

PURPOSE: To study vascular features detected with spectral domain optical coherence tomography (SD-OCT) in subjects undergoing retinopathy of prematurity (ROP) screening. DESIGN: Cross-sectional study. PARTICIPANTS AND CONTROLS: Fifty-seven premature neonates, 10 with plus disease in at least 1 eye and 47 without plus disease. METHODS: Bedside noncontact SD-OCT imaging was performed after obtaining parental consent on 97 consecutive infants between January 2009 and September 2012. Fifty-seven subjects (31-49 weeks' post-menstrual age) who had an SD-OCT scan in at least 1 eye showing the edge of the optic nerve and at least 1 major retinal vascular arcade were included. One eye per subject was randomly selected for analysis. Two masked graders evaluated scans for (1) retinal vessel elevation, (2) scalloped retinal layers, (3) hyporeflective vessels, and (4) retinal spaces. To coalesce the weight of these features, a Vascular Abnormality Score by OCT (VASO) was created. For quantitative assessment of vessel elevation, retinal surface maps were created. MAIN OUTCOME MEASURES: Prevalence of SD-OCT vascular abnormalities, the VASO, intergrader agreement, and presence of elevation on surface maps. RESULTS: From among 67 SD-OCT characteristics that were recorded, the most common characteristics found were vessel elevation (44%), hyporeflective vessels (40%), scalloped layers (22%), and retinal spaces (11%). Features significantly associated with plus disease were vessel elevation (P = 0.01), hyporeflective vessels (P = 0.04), and scalloped retinal layers (P = 0.006). Intragrader agreement was between 74% and 90% for all features. The VASO was significantly higher in subjects with plus disease (P = 0.0013). On 3-dimensional SD-OCT volumes, eyes with plus disease had greater retinal surface elevation that more often matched en face retinal vascular patterns. CONCLUSIONS: We present a novel 3-dimensional analysis of vascular and perivascular abnormalities identified in SD-OCT images of eyes with ROP. The SD-OCT characteristics that are more common in eyes with plus disease provide the first in vivo demonstration of the effects of vascular dilation and tortuosity on perivascular tissue. The VASO and surface maps also delineate the severity of vascular pathology in plus disease. Further studies evaluating these findings in eyes with pre-plus versus normal posterior pole vessels may determine the usefulness of SD-OCT in the early detection of vascular abnormalities in ROP.

PURPOSE: To evaluate effects of prematurity on early optic nerve (ON) development and the usefulness of ON parameters as indicators of central nervous system (CNS) development and pathology. DESIGN: Prospective, cross-sectional, longitudinal study. PARTICIPANTS: Forty-four preterm infants undergoing retinopathy of prematurity (ROP) screening and 52 term infants. METHODS: We analyzed ON from portable handheld spectral-domain optical coherence tomography (SD-OCT) images (Bioptigen, Inc, Research Triangle Park, NC) of 44 preterm and 52 term infants. The highest-quality ON scan from either eye was selected for quantitative analysis. Longitudinal analysis was performed at 31-36 weeks and 37-42 weeks postmenstrual age (PMA). Preterm ON parameters also were assessed for correlation with indicators of cognitive, language, and motor development and CNS pathology. MAIN OUTCOME MEASURES: Vertical cup diameter (vCD), vertical disc diameter (vDD), vertical cup-to-disc ratio (vCDR), cup depth, and indicators of neurocognitive development and CNS pathology. RESULTS: At 37-42 weeks PMA, preterm infants had larger vCD and vCDR than term infants (908 vs. 700 µm [P<0.001] and 0.68 vs. 0.53 µm [P<0.001], respectively), whereas cup depth and vDD were not significantly different. Longitudinal changes (n = 26 preterm eyes; mean interval, 4.7 weeks) in vDD and in vCDR were an increase of 74 µm (P = 0.008) and decrease of 0.05 (P = 0.015), respectively. In preterm infants (n = 44), periventricular leukomalacia was associated with larger vCD (1084 vs. 828 µm; P = 0.005) and vCDR (0.85 vs. 0.63; P<0.001), posthemorrhagic hydrocephalus was associated with shallower cup (331 vs. 456 µm; P = 0.030), and clinical magnetic resonance imaging was associated with larger vCDR (0.73 vs. 0.64; P = 0.023). In 23 preterm infants with Bayley Scales of Infant Development scores, larger vCDR was associated with lower cognitive scores (P = 0.049). CONCLUSIONS: This is the first analysis of ON parameters in premature infants using SD-OCT. It demonstrated that by age of term birth, vCD and vCDR are larger in preterm infants who were screened for ROP than in term infants. In this prospective pilot study, ON parameters in these preterm infants associate weakly with CNS pathology and future cognitive development. Future prospective studies with larger numbers are necessary before further conclusions can be made.

PURPOSE: To compare the macular morphology of pediatric versus adult eyes with epiretinal membrane (ERM) using spectral domain optical coherence tomography and identify characteristics associated with postoperative visual acuity. METHODS: This retrospective study analyzed spectral domain optical coherence tomography from pediatric subjects and a randomly selected cohort of adult subjects with ERM. Morphologic retinal and ERM features were graded by two masked spectral domain optical coherence tomography readers and compared with a postoperative change in visual acuity. RESULTS: Pediatric ERMs (age, 0.3-16.5 years) were more confluently attached to the retina than adult ERMs (age, 40-88 years; P = 0.009) and had less fibrillary appearance of the inner retina when separation was present (P = 0.044). Pediatric ERMs were associated with more vessel dragging (P = 0.019) and less external limiting membrane (P = 0.001) and inner segment band visibility (P = 0.010), with a trend toward foveal sparing by ERM (P = 0.051) and "taco" retinal folds (P = 0.052) compared with adult eyes. Visual acuity improvement was associated with intact (P = 0.048) and smooth (P = 0.055, trend) inner segment band in children and with smooth inner segment band (P = 0.083, trend) and visible external limiting membrane (P = 0.098, trend) in adults. CONCLUSION: We identified morphologic differences between pediatric and adult ERM on spectral domain optical coherence tomography. Similar to adults, photoreceptor integrity with pediatric ERM seems to predict better visual acuity changes after surgical ERM removal.

PURPOSE: To assess the cost-utility of prophylactic laser peripheral iridotomy (LPI) for primary angle closure (PAC) suspects (PACS). DESIGN: Economic evaluation. METHODS: Our Markov model randomized PACS eyes to LPI or observation for 40 one-year cycles (100,000 iterations per strategy). Each cycle, an eye remained in its current health state, advanced linearly through PAC, mild, moderate, severe, and end-stage PAC glaucoma (PACG), or died. Transition rates were derived from the literature including the Zhongshan Angle Closure Prevention (ZAP) trial and the Singapore Asymptomatic Narrow Angles Laser Iridotomy Study (ANA-LIS). Eyes with acute-angle closure advanced to either PAC or directly to various PACG severities. A tracker monitored accumulated perimetric decibel reduction to progress PACG through increasing severities, with an annual probability of either stable or severity-dependent perimetry loss. We set a willingness to pay of an incremental cost-effectiveness ratio (ICER) <$50,000/quality-adjusted life-years. RESULTS: At age 50 years, LPI was cost-saving using ZAP data and cost-effective using ANA-LIS data. The ZAP iterations became cost-effective from the societal perspective when the model started at age 55 years and third-party perspective at age 70 years. LPI was no longer cost-effective from the societal perspective using ANA-LIS data at age 80 years or from the societal perspective using ZAP data or third-party perspective with ANA-LIS data at age 85. Probabilistic sensitivity analyses favored LPI until starting age 85. CONCLUSIONS: Prophylactic LPI for PACS is cost-effective across a spectrum of ages and should be considered from a public health perspective.

INTRODUCTION: Malignant pleural effusion is a common finding in patients with advanced cancer and is a frequent cause of dyspnea. Current guidelines indicate thoracentesis for symptomatic patients, while indwelling pleural catheters (IPC) are recommended for patients who develop pleural fluid re-accumulation. IPC maintenance, however, requires a significant level of financial and social support. This study aims to analyze potential influencing factors that may play a role in the decision for placing IPCs in patients with recurrent malignant pleural effusions. METHODS: This study retrospectively collected baseline sociodemographic and laboratory data in patients who underwent thoracentesis for malignant pleural effusion from August 2016 to October 2021, and selected patients who presented with re-accumulation of pleural fluid within 30 days or had a pulmonary physician's note documenting that IPC is a potential management option. Of these selected patients (IPC candidates), we stratified patients who underwent IPC placement and those who did not, and performed statistical analysis between these 2 groups. RESULTS: One hundred seventy-six patients who underwent thoracentesis were regarded as IPC candidates. Almost all baseline sociodemographic characteristics, including ethnicity ( P =0.637), sex ( P =0.655), and marital status ( P =0.773) were similar between the 2 groups, but significantly higher ECOG scores ( P =0.049) were noted in the IPC group. No statistically significant differences were noted in age, body mass index, platelet, PTT, international normalized ratio, creatinine, white blood cell, red blood cells, fluid protein, or fluid lactate dehydrogenase. Fluid albumin ( P =0.057) and serum neutrophil:lymphocyte ratio ( P =0.003) were significantly higher in patients without IPC placement. CONCLUSION: This study did not recognize any baseline sociodemographic factors that may contribute to the decision to place IPCs.

This retrospective cohort study describes the real-world incidence and maintenance of clinically meaningful intraocular pressure (IOP) reduction ("response") following stand-alone phacoemulsification for 667,987 eyes with suspected or confirmed glaucoma in the IRIS Registry (Intelligent Research in Sight) from 1/1/2013-9/30/2019. Intraocular pressure responders had ≥ 20% IOP reduction in daily mean IOP from baseline on two consecutive postoperative visits. We declared failure if a responder no longer maintained ≥ 20% IOP reduction. The estimated IOP responder rate was 41.3% by Kaplan-Meier analysis. Multivariate analysis demonstrated relationships between IOP response and baseline IOP (hazard ratio (HR) (95% confidence interval)) 1.48 (1.48-1.49), per 3 mmHg, P < 0.0001), age (HR 1.14 (1.13-1.14), per 10 years, P < 0.0001), male sex (HR 1.13 (1.12-1.15), P < 0.0001), prostaglandin analogue (HR 0.88 (0.87-0.90), P < 0.0001), and Rho-kinase inhibitor use (HR 1.50 (1.32-1.70), P = 0.01). Fifty percent of IOP responders failed at a median time of 14.3 months. Multivariate analysis demonstrated relationships between failure and baseline IOP (HR 0.75 (0.75-0.76), per 3 mmHg, P < 0.0001), nitric oxide donating prostaglandin (HR 1.78 (1.46-2.18), P < 0.0001) and Rho-kinase inhibitor use (HR 1.73 (1.43-2.09), P < 0.0001). Clinicians may counsel glaucoma patients with risk factors on whether to anticipate an IOP response and its expected duration after stand-alone phacoemulsification.

PRCIS: About one-fourth of survey respondents from an ASCRS database initiate treatment for primary open angle glaucoma (POAG) with laser trabeculoplasty. Factors impacting physicians' choice of laser versus topical treatment for POAG were explored. PURPOSE: To characterize primary treatment preferences (topical medication versus laser trabeculoplasty or intracameral sustained release implants) in primary open angle glaucoma (POAG) patients and determine factors related to primary intervention selection. METHODS: A 33-question survey was distributed to an American Society of Cataract and Refractive Surgery database on treatment choices made by ophthalmologists for POAG. Data collected included country of practice, years of practice, completion of glaucoma fellowship training, type of practice, and preference for the first line of treatment for POAG. Multiple logit regression was used to compare the effect of covariates on physicians' choice of either topical medication or laser trabeculoplasty for POAG. RESULTS: A total of 252 of 19,246 (1.3%) surveys were returned. Almost three-quarters of respondents used topical medication as the first line of treatment for POAG (73.6%), whereas 26.4% preferred to start with laser treatment. Significant variables associated with the selection of laser (vs. drops) are practicing in the United States (odds ratio [OR] 2.85; 95% CI, 1.33-6.10), the more recent completion of ophthalmology residency (OR 1.95; 95% CI, 1.00-3.77), the greater volume of minimally invasive glaucoma surgeries (MIGS) (OR 1.68; 95% CI, 1.18-2.40), and a glaucoma patient base greater than 25% (OR 2.21; 95% CI, 1.09-4.48). CONCLUSIONS: For the first-line treatment of POAG, laser trabeculoplasty is more likely to be preferred, over topical drops, by U.S. physicians who are relatively new in practice, who have a larger glaucoma patient base, and who perform more MIGS.

PURPOSE: To compare glaucoma tube outcomes of wet age-related macular degeneration (AMD) eyes receiving anti-VEGF injections versus dry AMD eyes and no anti-VEGF. DESIGN: Retrospective clinical cohort study. PARTICIPANTS: Patients with wet AMD and a history of anti-VEGF within a year prior or after stand-alone glaucoma tube surgery and eyes with dry AMD and no history of anti-VEGF with at least 6 months of follow-up. Eyes with neovascular glaucoma or anti-VEGF for reason other than wet AMD were excluded. METHODS: A Kaplan-Meier analysis compared survival for wet versus dry AMD eyes. Failure was defined as intraocular pressure (IOP) > 21 mmHg or < 20% IOP reduction from baseline or IOP ≤ 5 mmHg for 2 consecutive postoperative visits starting at month 3, additional glaucoma surgery, or no light perception. Complete success was defined as no failure or medications at final follow-up. Hypertensive phase was defined for valved tubes as IOP > 21 mmHg within 3 months of surgery after a reduction to < 22 mmHg during the first postoperative week. Intraocular pressure, percent reduction in IOP, number of glaucoma medications, and early (< 1 year) and late (> 1 year) complications were compared through 5 years. MAIN OUTCOME MEASURES: Survival analysis, IOP, number of medications. RESULTS: Baseline IOP, number of medications, or tube type were not significantly different between wet (n = 24) and dry AMD eyes (n = 54). No wet AMD eyes failed versus 10 (18%) dry AMD eyes (P = 0.03). Five-year survival was estimated as 100% for wet AMD and 72% for dry AMD (P = 0.04). Wet AMD eyes had lower IOP (10.6 vs. 12.7 mmHg, P = 0.05), greater IOP reduction (60% vs. 49%, P = 0.04), fewer medications (1.2 vs. 2.1, P = 0.02), and more complete success (50% vs. 15%, P = 0.001) at final follow-up (32 vs. 36 months, P = 0.42). Fewer wet than dry AMD eyes experienced hypertensive phase (0/10 [0%] vs. 4/10 [40%], P = 0.04). There were no significant differences in early or late complications. CONCLUSIONS: Exposure to anti-VEGF may influence postoperative wound healing and capsule formation which may improve glaucoma tube surgical outcomes. Prospective data is needed to consider perioperative administration of anti-VEGF for glaucoma tube surgery.

PURPOSE: To describe real-world intraocular pressure (IOP) changes following stand-alone cataract surgery by comparing postoperative IOP to phakic fellow eyes. DESIGN: Retrospective clinical cohort study. METHODS: A total of 1,334,868 patients (336,060 with glaucoma and 998,808 without glaucoma) in the IRIS® Registry (Intelligent Research in Sight) underwent stand-alone phacoemulsification from 1 January 2013 to 30 September 2019 with a fellow eye that had subsequent cataract surgery. Postoperative daily mean IOP was compared between surgical and control eyes from postoperative day 1 to 90. A generalized linear model determined when the postoperative daily mean IOP stabilized to calculate a final mean IOP, which was then compared to baseline IOP. RESULTS: Postoperative daily mean IOP was initially greater for surgical than for control eyes because of an early postoperative IOP spike. By postoperative day 13, postoperative daily mean IOP was significantly lower for surgical than for control eyes every day through postoperative day 90 (P < .001). There was a mean (SD) decrease from baseline to final mean IOP of 1.55 (3.52) mm Hg or 7.79% for all surgical eyes, 1.91 (3.93) mm Hg or 8.89% for surgical eyes with glaucoma, and 1.37 (3.28) mm Hg or 7.24% for surgical eyes without glaucoma, respectively. There was a statistically significant decrease from baseline to the final mean IOP for all surgical eyes, surgical eyes without glaucoma, and all categories of pre-glaucoma and glaucoma (P < .0001 for all, excluding uveitic glaucoma [P = .0016]). CONCLUSIONS: Eyes both with and without glaucoma that underwent stand-alone phacoemulsification had a significant decrease in IOP through the 90-day postoperative period compared to baseline and phakic fellow eyes.

BACKGROUND: Computed tomography (CT)-guided transthoracic needle biopsy is an important diagnostic tool for pulmonary nodules, offering a less invasive alternative to surgical procedures. This study aims to better risk stratify patients undergoing this procedure by analyzing the pulmonary function testing (PFT), imaging characteristics, and patient demographics most associated with complications. PATIENTS AND METHODS: This retrospective study involved 254 patients undergoing transthoracic needle biopsies at 3 hospitals between October 2016 and December 2019. Demographic data, extent of emphysema, and target lesion characteristics were recorded. Complications were defined as minor (small pneumothorax, mild hemoptysis, or pulmonary hemorrhage) and major (pneumothorax requiring chest tube, hemothorax, rapid atrial fibrillation, or postprocedure hypotension or hypoxia). RESULTS: There were 50 minor (20%) and 18 major complications (7%). As seen with prior studies, older age, increased distance to pleura, and smaller nodule size correlated with an increased risk of complications. Uniquely to our study, emphysema severity, seen on CT (P=0.008) and with decreased forced expiratory volume/forced vital capacity ratio, conferred an increased risk (62.94 vs. 68.74, P=0.05) of complications. Decreased Hounsfield unit of surrounding lung (a surrogate measure of emphysema) and decreased diffusion capacity (11.81 vs. 14.93, P=0.05) were associated with increased risk of major complications. Interestingly, body mass index and comorbidities had no correlation with complications. CONCLUSION: In addition to previous well-described characteristics, we described physiological data (abnormal PFTs), imaging findings, and nodule location as risk factors of procedural complications. Obtaining preprocedural PFT, in addition to reviewing CT imaging and demographic data, may aid clinicians in better risk stratifying patients undergoing transthoracic needle biopsies.

Purpose: This study investigated the effect of interview format changes (in-person to virtual, one-to-one to multiple-to-one) necessitated by the COVID-19 travel restrictions on preliminary fellowship candidate ranking variabilities. Design: Cross-sectional observational study. Method: In 2018 and 2019, the glaucoma fellowship interviews were conducted in-person in a one-to-one format, whereas in 2020, interviews were virtual and in a multiple (interviewers)-to-one (candidate) format. We compared ranking ranges of interviewers within the same virtual room (WSR) and not within the same virtual room (NWSR) to assess the effect of WSR versus NWSR on ranking variabilities. We also compared ranking categories ("accept," "alternate," and "pass") agreements between 2018, 2019, and 2020 to assess the effect of virtual versus in-person interviews on ranking variabilities. Results: NWSR and WSR mean rankings differed by 1.33 (95% confidence interval difference 0.61 to 2.04, p = 0.0003), with WSR interviewers having less variability than NWSR pairs. The variability between 2018/2019 (in-person interviews) and 2020 (virtual interviews) showed no differences between in-person and virtual interviews (weighted Kappa statistic 0.086 for 2018, 0.158 for 2019, and 0.101 for 2020; p < 0.05 for all years). The overall least attractive candidate has the lowest variability; the most attractive candidate has the second lowest variability. Conclusion: Grouping interviewers WSR during the interview decreased ranking variabilities compared to NWSR, while a change from in-person to virtual interview format did not increase the ranking variabilities. This suggests that the decreased nonverbal interactions in virtual interviews do not decrease interviewers' perceptions as applied to preliminary rankings.
RESUMO
PRCIS: Glaucoma cascade screening in first-degree relatives (FDRs) of young Haitian glaucoma patients had high yield for diagnosing manifest and suspected glaucoma in 30.8% of those screened despite modest participation. PURPOSE: To evaluate the outcomes of glaucoma cascade screening in FDRs (parents, siblings, and offspring) of Haitian juvenile open-angle glaucoma (JOAG) patients. PATIENTS AND METHODS: Consecutive index patients (Haitians with JOAG) were identified, and the number/type of FDRs residing in South Florida were recorded. These FDRs were invited for free glaucoma screening, which included a comprehensive ophthalmic exam, gonioscopy, automated visual field testing and optical coherence tomographic analysis of the retinal nerve fiber layers. FDR characteristics and clinical findings from screening are reported. RESULTS: A total of 77 FDRs were invited, 26 (33.8%) agreed to undergo screening (18 females, 9 males), which revealed 2 (7.7%) with manifest glaucoma (mean age 77.5 y; one of whom was previously unaware of his glaucoma diagnosis), 6 (23.1%) with suspected glaucoma (mean age 29.8±18.3 y), and 18 (69.2%) without manifest or suspected glaucoma (mean age 37.2±21.8 y). Siblings of index patients were least likely to participate in cascade glaucoma screening when compared with index patients' parents or offspring. FDR eyes with manifest glaucoma had significantly worse best-corrected visual acuities, higher intraocular pressures, thinner central corneal thicknesses, and thinner circumferential papillary retinal nerve fiber layer thicknesses than those without glaucoma. CONCLUSION: Glaucoma cascade screening of Haitian JOAG patients' FDRs revealed that 30.8% had suspected or manifest glaucoma. Future efforts centered on provider-initiated recruitment and improving public glaucoma awareness and education may increase screening participation.

Photoexcited radical reactions are critical to processes in both nature and materials, and yet they can be challenging for electronic structure methods due to the presence of strong electron correlation. Reduced-density-matrix (RDM) methods, based on solving the anti-Hermitian contracted Schrödinger equation (ACSE) for the two-electron RDM (2-RDM), are examined for studying the strongly correlated mechanisms of these reactions with application to the electrocyclic interconversion of allyl and cyclopropyl radicals. We combine recent extensions of the ACSE to excited states [G. Gidofalvi and D. A. Mazziotti, Phys. Rev. A 80, 022507 (2009)] and arbitrary spin states [A. E. Rothman, J. J. Foley IV, and D. A. Mazziotti, Phys. Rev. A 80, 052508 (2009)]. The ACSE predicts that the ground-state ring closure of the allyl radical has a high 52.5 kcal/mol activation energy that is consistent with experimental data, while the closure of an excited allyl radical can occur by disrotatory and conrotatory pathways whose transition states are essentially barrierless. Comparisons are made with multireference second- and third-order perturbation theories and multireference configuration interaction. While predicted energy differences do not vary greatly between methods, the ACSE appears to improve these differences when they involve a strongly and a weakly correlated radical by capturing a greater share of single-reference correlation that increases the stability of the weakly correlated radicals. For example, the ACSE predicts a -39.6 kcal/mol conversion of the excited allyl radical to the ground-state cyclopropyl radical in comparison to the -32.6 to -37.3 kcal/mol conversions predicted by multireference methods. In addition, the ACSE reduces the computational scaling with the number of strongly correlated orbitals from exponential (traditional multireference methods) to quadratic. Computed ground- and excited-state 2-RDMs are nearly N-representable.
RESUMO
Pediatric patients who undergo intraocular surgery are at risk for many of the same perioperative complications as adults. The same methodical approach to assessing perioperative shallowing of the anterior chamber that presents in the adult population should be followed for children. We present a rare case of intraoperative ciliary block in a 3-year-old boy undergoing a second glaucoma drainage device implantation that was successfully treated with pars plana vitrectomy and hyaloid-zonulo-iridectomy.
