Visual Outcomes and Risk of Endophthalmitis in Open Globe Injuries without Intraocular Foreign Bodies with Delayed Repair.

OBJECTIVE: To assess and compare the rate of endophthalmitis and visual outcomes in cases of OGI's without intraocular foreign bodies repaired within and greater than 24 hours from the time of injury. DESIGN: A retrospective review of 2,002 cases of OGI's presenting to a single institution. SUBJECTS, PARTICIPANTS, AND/OR CONTROLS: Patients with OGI's were admitted and managed according to a standardized protocol. METHODS, INTERVENTION, OR TESTING: The impact of timing of repair was assessed between those undergoing OGI repair within (i) 24 hours, (ii) 25-36 hours, and (iii) greater than 36 hours from the time of injury. MAIN OUTCOME AND MEASURE: Rates of endophthalmitis and postoperative visual acuity of logMAR 1.3, logMAR 1.0, and logMAR 0.3 at 180 days and 1 year following open globe repair. RESULTS: 1,382 patients with OGI's were included, of which 75% were male with an average age of 41 years. Maximal zone of injury was zone 1 for 468 patients, zone 2 for 529 patients and zone 3 for 508 patients. 84% of all OGI's underwent repair within 24 hours from the time of injury, 9% from 25-36 hours, and 7% greater than 36 hours. Average preoperative visual acuity was hand motion. Risk factors associated with repair performed greater than 36 hours from the time of injury included female sex (p=0.042). Endophthalmitis was associated with time to repair greater than 36 hours (p=0.049) but not with 25-36 hours or zone of injury (p=0.111). Time to repair had no significant impact on visual acuity outcomes. CONCLUSIONS: Although repair of OGI's within 24 hours is the current standard of care, this study found no statistically significant difference in rates of endophthalmitis or visual outcomes in eyes undergoing repair within 24 hours of injury compared to repair extending to 25 to 36 hours . Endophthalmitis rates did increase after 36 hours. We recommend urgent repair of open globe injuries, but in certain circumstances, it may be reasonable to delay repair beyond 24 hours to optimize operating conditions.

Iris freckle: a distinct entity.

PURPOSE: To report distinctive clinical and imaging features of iris freckles to differentiate them from iris nevi. DESIGN: Retrospective observational study. SUBJECTS: 53 patients (277 freckles) with incidental iris freckles and 102 patients (104 nevi) with iris nevi that are either clinically stable or pathologically confirmed. METHODS: Patient data were collected from the Department of Ophthalmic Oncology, Cleveland Clinic, Cole Eye Institute database (2012-2023). Lesion characteristics were recorded from slit-lamp examination descriptions and review of colour photographs. Ancillary imaging features observed using anterior segment optical coherence tomography (AS-OCT) and ultrasound biomicroscopy (UBM) were assessed in patients (where available). MAIN OUTCOME MEASURES: Comparison of clinical and imaging features of iris freckles and iris nevi. RESULTS: A total of 277 iris freckles and 104 iris nevi were analysed. Iris freckles were more frequently bilateral (17%; nevi 0%) and multiple (69%; nevi 2%) and located centrally (89%; nevi 17%) compared with iris nevi (p<0.001). The median freckle largest basal diameter and thickness were 0.8 mm (nevi; 2.1 mm, p<0.001) and 0.04 mm (nevi 1.0 mm, p<0.001), respectively. All iris freckles had irregular margins without any secondary effects compared with iris nevi. Iris freckles appeared flat without effacement of iris folds compared with iris nevi on AS-OCT (p<0.001). Iris freckles were not detectable by UBM. Heat map revealed that freckles demonstrated several features with uniform or near uniform values, whereas nevi demonstrated more variability in values across features. CONCLUSIONS: Iris freckles exhibit specific clinical and imaging features reflective of their characteristic histological composition that support their classification as a distinct entity within the spectrum of iris pigmented lesions.

Choroidal Nevi in Children: Size, Growth, and Topographic Distribution.

PURPOSE: To explore size, growth, and topographic distribution of choroidal nevi in children to gain insights into choroidal nevogenesis. DESIGN: Retrospective consecutive case series using pediatric clinic - and population-study data, comparing to adult data. METHODS: Clinical data from Cole Eye Institute (CEI) database (December 2005-January 2023) was derived from a retrospective consecutive case series of 20 children (< 20 years) with choroidal nevi. For population data, 48 children from previously reported pooled data of the participants of the Sydney Pediatric Eye Disease Study, Sydney Myopia Study, Sydney Childhood Eye Study, and Sydney Adolescent Vascular and Eye Disease Study were included. Fundus photographs were reviewed and the locations of 18 choroidal nevi seen at CEI with widefield imaging were mapped on a radial scatter plot. For comparison, 100 consecutive adults with choroidal nevi were identified from CEI database. Main outcomes were size, growth, and topographic distribution of choroidal nevi. RESULTS: The median largest basal diameter was 1.6 mm (range 0.4-4.2) in children. Most choroidal nevi (75%) remained stable, and 16% demonstrated growth at follow-up. The mean growth rate was calculated as 0.12 mm/year (range 0.10-0.15). Malignant transformation was not noted during childhood. All secondary changes (drusen, orange pigment, and subretinal fluid) associated with choroidal nevi in children were less common than those in adults (p < .05). Choroidal nevi in children were located significantly more posterior than in adults. The median distance to fovea was 2.1 mm (range 0.5-8.5) in children and 5.1 mm (range 0.4-16) in adults (p < .0001). CONCLUSIONS: The onset and growth of choroidal nevi in children suggest active choroidal nevogenesis in childhood. A posterior topographic distribution may support the developmental framework for migration and maturation of choroidal melanoblasts.

En Face Depth Resolved OCTA Monitoring of Macular Outer Retinal Deposits in a Case of Multifocal Choroiditis Mimicking Syphilitic Uveitis.

PURPOSE: Multifocal choroiditis (MFC) is a rare inflammatory condition characterized by retinal and choroidal lesions that may present similarly to ocular pathology of various etiologies. Here we present a case of MFC mimicking syphilitic uveitis with unique en face optical coherence tomography angiography (OCTA) imaging characteristics. METHODS: Case report. RESULTS: A 61-year-old woman presented with blurry vision, floaters and multiple whitish subretinal deposits on en face swept-source OCTA in the left eye. Fluorescent treponemal antibody test absorption was positive which led to the initial diagnosis of syphilitic uveitis and subsequent treatment with intravenous penicillin. During follow-up, OCTA of the left eye revealed the development of new choroidal neovascular membrane and new punched-out lesions in the posterior pole. The patient was eventually diagnosed with MFC and treated with aflibercept injections. CONCLUSIONS: Immune-mediated uveitis can simulate infectious and neoplastic uveitis. En face OCTA is unique imaging modality that allowed for the complete characterization and monitoring of the sub-macular deposits. This expands the clinical spectrum of multifocal choroiditis.

Peripheral Hemorrhagic Chorioretinopathy: Differentiating Features from Choroidal Melanoma.

Introduction: Peripheral exudative hemorrhagic chorioretinopathy (PEHCR) is one of the leading mimickers of choroidal melanoma because of overlapping features with choroidal melanoma that make the distinction between these two entities difficult. Methods: To identify nonoverlapping diagnostic features between PEHCR and choroidal melanoma, a retrospective study of 80 patients (80 eyes); 40 patients (40 eyes) with PEHCR; and 40 patients (40 eyes) with choroidal melanoma was conducted. Ophthalmoscopic and imaging features of PEHCR and choroidal melanoma were compared. Sensitivity and specificity for identifying PEHCR and choroidal melanoma were calculated. Youden's J statistic was assessed for each diagnostic feature. Results: The most frequent clinical features of PEHCR were presence of druse (100%), hemorrhagic PED (93%), dome-shaped mass (B-scan) (90%), and subretinal/intraretinal hemorrhage (78%). Statistical analysis confirmed high sensitivity of hemorrhagic PED (0.93; 95% CI 0.80-0.98) and high specificity of clot retraction cleft, presence of lipid exudation, and bilaterality (1.00; 95% CI 0.91-1.00) as diagnostic features of PEHCR. Statistical analysis revealed presence of subretinal fluid 0.80 (95% CI 0.54-0.91) was most sensitive and presence of orange pigment, mushroom shape on B-scan, ciliary body extension, and choroidal excavation were most specific (1.00; 95% CI 0.91-1.00) for choroidal melanoma. Nonoverlapping diagnostic features of PEHCR were hemorrhagic PED, clot retraction cleft, presence of lipid exudation, and bilaterality. All PEHCR patients (100%) had at least one of these nonoverlapping diagnostic features. Nonoverlapping diagnostic features of choroidal melanoma were the presence of orange pigment, choroidal excavation, mushroom-shaped mass, and ciliary body extension (the latter 3 detected on B-scan). Youden's J statistic was highest for hemorrhagic PED and lowest for dome-shape appearance on B-scan (0.075). Conclusion: PEHCR and choroidal melanoma can be differentiated by identifying diagnostic features that are exclusive to each entity. The presence of hemorrhagic PED strongly supports a diagnosis of PEHCR. B-scan ultrasonography is required to detect a mushroom-shaped mass, choroidal excavation, or ciliary body extension to exclude underlying choroidal melanoma.

Uveal Melanoma in BAP1 Tumor Predisposition Syndrome: Estimation of Risk.

PURPOSE: To estimate point prevalence of uveal melanoma in the patients with germline BAP1 pathogenic variant. DESIGN: Cohort study with risk assessment using Bayesian analysis. METHODS: The point prevalence estimate was obtained by Bayes's rule of reverse conditional probabilities. The probability of uveal melanoma given that BAP1 mutation exists was derived from the prevalence of uveal melanoma, prevalence of germline BAP1 pathogenic variants, and the probability of germline BAP1 pathogenic variant given that uveal melanoma is present. Confidence intervals (CIs) for each variable were calculated as the mean of Bernoulli random variables and for the risk estimate, by the delta method. The age at diagnosis and the gender of the uveal melanoma patients with BAP1 germline pathogenic variants obtained from previous publications or from authors' unpublished cohort was compared with those in the Surveillance, Epidemiology, and End Results (SEER) database. RESULTS: The point prevalence of uveal melanoma in patients with the germline BAP1 pathogenic variants in the US population was estimated to be 2.8% (95% CI, 0.88%-4.81%). In the SEER database, the median age at diagnosis of uveal melanomas was 63 (range 3-99 years) with a male-to-female ratio of 1.01:1. In comparison, uveal melanoma cases with BAP1 germline pathogenic variants from the US population (n = 27) had a median age at diagnosis of 50.5 years (range 16-71). CONCLUSIONS: Quantification of the risk of developing uveal melanoma can enhance counseling regarding surveillance in patients with germline BAP1 pathogenic variant.

An Online Application for Retinoblastoma Surveillance.

BACKGROUND: Retinoblastoma (RB) is a potentially heritable childhood cancer that is vision- and life-threatening. Assessing the risk of inheriting RB is important for structuring ophthalmic and genetic screening of family members. PURPOSE: To create a free online application that integrates phenotypic, genetic, and familial relationships with clinical best practice surveillance guidelines for families with RB. METHODS: The risk of germline RB1 gene mutation was assessed for first- and second-degree relatives of a proband under variable clinical scenarios, integrating age, phenotype, relationship data, and genotype (germline RB1 mutation status: detected, undetected, not tested). Based on the assessed risk of a germline RB1 mutation, recommendations regarding further genetic testing as well as ophthalmic surveillance were derived from consensus guidelines. RESULTS: The recommendations depend on the RB1 germline mutation status (detected, undetected, not tested), which were further subcategorized by the results of tumor phenotype, relationship to proband, age of the relative, and family structure. The online application is available at https://nakul-singh.shinyapps.io/RB_Screening_rec/. CONCLUSIONS: The assessed risk of germline RB1 mutation determines ophthalmic surveillance recommendations. The tool may have most value in regions where access to specialized care is limited.

Fine-needle aspiration biopsy for suspected uveal metastases.

OBJECTIVE: One indication of fine-needle aspiration biopsy (FNAB) is the diagnostic confirmatory of a clinical suspicion of uveal metastasis. We analyzed our experience in this clinical setting to assess the effectiveness of FNAB technique. DESIGN: Retrospective study. PARTICIPANTS: 28 patients (28 eyes) underwent FNAB biopsy. METHODS: Aspirates were performed using 25-gauge needle and were classified into the following categories: positive, atypical, negative, or nondiagnostic. The electronic medical records provided all clinical data. Subsequent clinical course was considered as the diagnostic standard. RESULTS: Subsequent clinical course was metastatic tumour in 19 cases (68%) and nonmetastatic tumour in other 9 cases, considered as the diagnostic standard. Cytological interpretations for metastases were positive in 19 cases (68%), atypical in 2 cases (7%), negative in 4 cases (14%), and nondiagnostic in 3 cases (11%). The metastasis-positive cases included 9 adenocarcinoma, 3 uveal lymphoma, 3 small cell carcinomas, 3 non-small cell carcinomas, and 1 metastatic paraganglioma. Both of the atypical cases were suggestive for non-Hodgkin lymphoma. The 4 negative cases for metastases included 2 true negative cases, and 2 false negative aspirates that subsequently proved to be metastatic adenocarcinoma. The 3 nondiagnostic cases included 1 schwannoma, 1 low-grade uveal non-Hodgkin lymphoma, and 1 metastatic adenocarcinoma. The overall sensitivity for FNAB was 87.5%, with a specificity of 100%. CONCLUSIONS: FNAB of suspected uveal metastases is a reliable diagnostic technique.

Diagnostic A-Scan of Choroidal Melanoma: Automated Quantification of Parameters.

AIM: To develop an automated algorithm to quantify ultrasonographic A-scan parameters of choroidal melanoma. METHODS: The study included 100 consecutive patients with a clinical diagnosis of choroidal melanoma. Ultrasonographic A-scans (8 MHz, 1,550 m/s, tissue sensitivity = 67 dB) were performed by standard techniques. We created and then utilized a MATLAB® script to generate four quantifiable A-scan parameters: (1) tumor height (mm), (2) the number of internal reflectivity peaks (numerical value), (3) median internal reflectivity (%), and (4) angle κ (°). RESULTS: There were small (≤2.5 mm, n = 32), medium (2.6-10.0 mm, n = 53), and large (> 10.0 mm, n = 14) tumors. The mean number of internal reflectivity peaks counted between the two tumor boundary spikes (surface and base) was 10.0 (σ = 8.7, range 1-37). The median value of the internal reflectivity peaks for all cases varied from 19.8 to 99.5 (mean = 68.3, σ = 20.5). A statistically significant correlation was observed between the tumor height categories and each of the three A-scan parameters: the number of internal reflectivity peaks (ρ = 0.90, p < 0.01), median internal reflectivity (ρ = -0.63, p < 0.01), and a positive angle κ (ρ = -0.32, p = 0.03). CONCLUSIONS: An automated algorithm can provide quantifiable A-scan parameters for choroidal melanoma.

Diagnostic A-Scan of Choroidal Tumors: Comparison of Quantified Parameters.

AIM: To compare quantified ultrasonographic A-scan parameters of common choroidal tumors. METHODS: Consecutive patients with a clinical diagnosis of choroidal melanoma (n = 100), choroidal nevus (n = 30), choroidal metastasis (n = 10), and circumscribed choroidal hemangioma (n = 10) were included in this study. Ultrasonographic A-scans (8 MHz, 1,550 m/s, tissue sensitivity = 67 dB) were performed by standard techniques. Using a custom made MATLAB® script, four quantifiable A-scan parameters: tumor height (mm), number of internal reflectivity peaks (numerical value), median internal reflectivity (%), and angle κ (°) were obtained for all (n = 150) tumors. RESULTS: The mean number of internal reflectivity peaks for choroidal nevus, choroidal metastasis, and circumscribed choroidal hemangioma was 3.1, 5.1, and 4.0, respectively. The median internal reflectivity for choroidal melanoma varied from 21.5 to 99.5% (mean = 76.4%). The median internal reflectivity was ≥65% in all choroidal nevus (100%), choroidal metastasis (100%), and circumscribed choroidal hemangioma (100%), and majority of the choroidal melanoma (78%). CONCLUSIONS: The quantified A-scan patterns of common choroidal tumors were significantly influenced by the tumor height. Other than median internal reflectivity of < 65%, which seems to distinguish choroidal melanoma from other tumors (choroidal nevus, choroidal metastasis, and circumscribed choroidal hemangioma), there were no specific diagnostic patterns.

Variability of Bad Prognosis in Uveal Melanoma.

TOPIC: Survival of patients with uveal melanoma classified to have a bad prognosis. CLINICAL RELEVANCE: To explore reasons for reported variability in survival of patients with uveal melanoma classified to have a bad prognosis. METHODS: We searched PUBMED, MEDLINE, and EMBASE for studies reporting survival data for uveal melanoma undergoing prognostic testing with chromosome 3 status by fluorescence in situ hybridization (FISH), comparative genomic hybridization (CGH), microsatellite analysis (MSA), multiplex ligation-dependent probe amplification (MLPA), single nucleotide polymorphism (SNP), gene expression profiling (GEP) class, and exon sequencing. Only studies reporting 1-year, 3-year, or 5-year survival were included in the study. RESULTS: The initial search resulted in 49 studies. Only 12 studies met inclusion criteria. Three studies reported survival data for FISH, 1 study reported survival data for CGH, 1 study reported survival data for MSA, 3 studies reported survival data for MLPA, 3 studies reported survival data for SNP, 3 studies reported survival data for GEP, and 2 studies reported survival data for a combination of tests. No studies reported survival data for exon sequencing. Six studies reported percent free of metastatic death, 2 studies reported metastasis-free survival (MFS), 2 studies reported overall survival (OS), and 2 studies reported probability of metastasis. Metastasis-free survival (5 years) for monosomy 3 by FISH was 40% to 60%, by MLPA was 30% to 40%, by SNP was 72%, and for GEP class 2 was not reported. Overall survival (5 years) for monosomy 3 and disomy 8 tumors by MLPA and GEP class 2 were not comparable (81% and 55%, respectively). CONCLUSIONS: Variability exists in reported survival for uveal melanoma with a bad prognosis. Several factors, including composition of study population (tumor size, exclusion of iris melanoma, duration of median follow-up), method of obtaining tumor sample, type of prognostic test, and use of variable outcome measures, can explain some of the observed differences in survival. Variations in determining the cause of death (metastatic or nonmetastatic) may be the major reason for the observed differences. Standardization of study methods and outcome measures will allow comparison of survival data derived from different prognostic tests.

Extranodal Marginal Zone Lymphoma of Ocular Adnexa: Outcomes following Radiation Therapy.

AIM: The aim of this study was to report outcomes following radiation therapy in patients with biopsy-proven extranodal marginal zone lymphoma of the ocular adnexa and uvea. METHODS: Records from a single institution were retrospectively reviewed from January 1997 to December 2015. The mean follow-up duration was 38 months (range 0-194). Radiation therapy was administered to 77 eyes (60 patients); 57 of the 77 eyes (74%) were treated with radiation only (range 20-36 Gy, median 15 fractions). Radiation cataract, radiation retinopathy, and optic neuropathy assessments were performed on all eyes treated with radiation. RESULTS: 100% of the 47 patients treated with radiation therapy only had local control with an average dose of 26.5 Gy (median 25.2 [range 20-36] Gy; 150-200 cGy per fraction). Four patients lost 2 lines or more of vision after radiation. The most common complication of radiation therapy was cataract formation/progression in 19 eyes (25%). Radiation retinopathy was observed only in 1 patient (1%). CONCLUSION: Our results confirm that radiation therapy (median 25 Gy) for extranodal marginal zone lymphoma of the ocular adnexa is associated with high local control and low risk of visually significant complications.

Iodine-125 Brachytherapy for Uveal Melanoma: A Systematic Review of Radiation Dose.

AIM: To investigate whether lower radiation doses may yield similar outcome measures to those from the COMS trial. METHODS: A literature review of English language articles was performed using the PubMed database of the U.S. National Library of Medicine and the Cochrane Central Register of Controlled Trials using the following keywords: uveal melanoma, choroidal melanoma, primary uveal malignant melanoma, iodine-125 brachytherapy, local recurrence, local treatment failure, and local tumor control. The relationships between study local recurrence rate and median dosage were tested by linear regression, with each study weighted by the number of patients included. RESULTS: Fifteen retrospective and prospective studies were selected for systematic review (2,662 patients). Ranges of reported mean or median radiation dose to tumor apex were 62.5-104.0 Gy. Local recurrence rates ranged from 0 to 24%. A 1.0-Gy increase in the average study dose was associated with a 0.14% decrease in local recurrence rate, which was not statistically significant (p value 0.336). CONCLUSION: The gold standard empirically derived 85.0-Gy radiation dose for the treatment of uveal melanoma could be tested in a randomized study.

Uveal Melanoma Regression after Brachytherapy: Relationship with Chromosome 3 Monosomy Status.

AIM: The objective was to evaluate the relationship between the regression rate of ciliary body melanoma and choroidal melanoma after brachytherapy and chromosome 3 monosomy status. METHODS: We conducted a prospective and consecutive case series of patients who underwent biopsy and brachytherapy for ciliary/choroidal melanoma. Tumor biopsy performed at the time of radiation plaque placement was analyzed with fluorescence in situ hybridization to determine the percentage of tumor cells with chromosome 3 monosomy. The regression rate was calculated as the percent change in tumor height at months 3, 6, and 12. The relationship between regression rate and tumor location, initial tumor height, and chromosome 3 monosomy (percentage) was assessed by univariate linear regression (R version 3.1.0). RESULTS: Of the 75 patients included in the study, 8 had ciliary body melanoma, and 67 were choroidal melanomas. The mean tumor height at the time of diagnosis was 5.2 mm (range: 1.90-13.00). The percentage composition of chromosome 3 monosomy ranged from 0-20% (n = 35) to 81-100% (n = 40). The regression of tumor height at months 3, 6, and 12 did not statistically correlate with tumor location (ciliary or choroidal), initial tumor height, or chromosome 3 monosomy (percentage). CONCLUSION: The regression rate of choroidal melanoma following brachytherapy did not correlate with chromosome 3 monosomy status.

Maintaining Interrater Agreement of Core Assessment Instruments in a Multisite Randomized Controlled Clinical Trial: The Randomized Evaluation of Sedation Titration for Respiratory Failure (RESTORE) Trial.

BACKGROUND: RESTORE (Randomized Evaluation of Sedation Titration for Respiratory Failure) was a cluster randomized clinical trial evaluating a sedation strategy in children 2 weeks to <18 years of age with acute respiratory failure supported on mechanical ventilation. A total of 31 U.S. pediatric intensive care units (PICUs) participated in the trial. Staff nurse rater agreement on measures used to assess a critical component of treatment fidelity was essential throughout the 4-year data collection period. OBJECTIVE: The purpose of the study is to describe the method of establishing and maintaining interrater agreement (IRA) of two core clinical assessment instruments over the course of the clinical trial. METHODS: IRA cycles were carried out at all control and intervention sites and included a minimum of five measurements of the State Behavioral Scale (SBS) and Withdrawal Assessment Tool-Version 1 (WAT-1). Glasgow Coma Scale scores were also obtained. PICUs demonstrating <80% agreement repeated their IRA cycle. Fleiss's kappa coefficient was used to assess IRA. RESULTS: Repeated IRA cycles were required for 8% of 226 SBS cycles and 2% of 222 WAT-1 cycles. Fleiss's kappa coefficients from more than 1,350 paired assessments were .86 for SBS and .92 for WAT-1, demonstrating strong agreement and similar to .91 for the Glasgow Coma Scale. There was no difference in Fleiss's kappa for any of the instruments based on unit size or timing of assessment (earlier or later in the study). For SBS scores, Fleiss's kappa was significantly different in larger and smaller PICUs (.82 vs. .92, p = .003); however, Fleiss's kappa for both groups indicated excellent agreement. CONCLUSION: Monitoring measurement reliability is an essential step in ensuring treatment fidelity and, thus, the validity of study results. Standardization on the use of these core assessment instruments among participating sites was achieved and maintained throughout the trial.

Impact of Infant-Polysomnography Studies on Discharge Management and Outcomes: A 5 Year Experience from a Tertiary Care Unit.

OBJECTIVE: To evaluate the impact of infant-polysomnography studies performed in the NICU on management and outcomes. STUDY DESIGN: Retrospective study to collect demographics and data on infant-polysomnography studies between Jan 2010 to Dec 2014. RESULTS: 110 premature neonates had polysomnography study performed at 36.9 ± 2.5 weeks post menstrual age. Almost all the studies were read as abnormal and 95% of the studied infants were discharged home on a cardiorespiratory monitor. 20% of the subjects had apnea >20 s, 18% had apnea of 15-20 s and 50% of infants had apnea of 10-15 s. 24.5% infants were discharged home on caffeine, 28% on metoclopramide and 24% on antacids. There were 11 readmissions for apparent life threatening events with no until 6 month-corrected age. There was no association between polysomnography results and readmission. There was a decline in polysomnography studies performed each year. CONCLUSION: Cardiorespiratory monitoring, medications and polysomnography studies do not predict outcomes.
