RESUMO

PURPOSE: To determine factors associated with visual and anatomic outcomes of suprachoroidal hemorrhage (SCH) in studies published between 1990 and 2022. METHODS: Individual participant data (IPD) systematic review. The protocol was prospectively registered on Open Science Framework (https://osf.io/69v3q/). PubMed, EMBASE, Web of Science, and Google Scholar were searched for peer-reviewed studies of SCH with ≥3 patients published between January 1, 1990, and September 1, 2022. The primary outcome was the change in logarithm of the minimum angle of resolution (logMAR) visual acuity (VA) from the time of SCH diagnosis to last follow-up. RESULTS: 413 eyes from 49 studies were included, with mean (SD) age 60.8 (22.4) years and mean (SD) follow-up of 13.8 (12.6) months. Among 145 eyes with at least 6 months of follow-up, the mean (SD) gain in VA was -0.98 (0.89) logMAR. In multivariable regression, treatment with systemic steroids was associated with greater improvement in logMAR VA (adjusted mean (SE) -1.29 (0.09) versus -0.16 (0.30) for no systemic steroids; P < 0.001) and greater odds of achieving anatomic success (adjusted OR 10.59, 95% CI 2.59 to 43.3; P = 0.001). CONCLUSIONS: The use of systemic steroids was associated with better visual and anatomic outcomes for SCH.

RESUMO

TOPIC: To characterize the presentation, management, and outcomes of suprachoroidal hemorrhage (SCH). CLINICAL RELEVANCE: Suprachoroidal hemorrhage is a potentially devastating condition but there is no high-quality evidence for the prognosis or management of SCH. METHODS: We performed a systematic review and meta-analysis of peer-reviewed studies of SCH published in PubMed, EMBASE, Web of Science, or Google Scholar between January 1, 1990, and September 1, 2022. The protocol was prospectively registered on the Open Science Framework (https://osf.io/69v3q/). Random-effects models were used to calculate the pooled estimate and 95% confidence intervals (CIs) for visual acuity (VA) and anatomic outcomes. Univariable and multivariable random-effects meta-regressions were performed to determine factors associated with VA outcomes and anatomic success, defined as the retina attached at the last follow-up. RESULTS: Sixty-eight studies comprising 1246 eyes of 1245 patients were included, with mean (standard deviation [SD]) follow-up of 14.0 (9.4) months. The pooled estimate (95% CI) for mean change in logarithm of the minimum angle of resolution (logMAR) VA from baseline to the last follow-up was -0.98 (-1.22 to -0.74) (I2 = 88.4%), with 72.0% (63.5%-80.5%) (I2 = 74.3%) achieving VA improvement of ≥ 0.3 logMAR (3-line improvement in ETDRS VA), 39.6% (32.5%-46.7%) (I2 = 83.2%) achieving final VA of 1.0 logMAR (Snellen equivalent 20/200) or better, and 75.5% (68.4%-82.7%) (I2 = 74.7%) achieving anatomic success. Studies with predominantly nonspontaneous SCH and greater percent of eyes receiving systemic steroids were associated with greater improvement in logMAR VA, a greater proportion of eyes with VA improvement ≥ 0.3 logMAR, and greater proportion of eyes achieving anatomic success (all P < 0.05 univariable meta-regression). Studies with greater percent of eyes treated surgically were associated with greater proportion of eyes with VA improvement of ≥ 0.3 logMAR in (P < 0.05, univariable and multivariable analysis). The mean (SD) quality score across studies was 13.9 (2.3) out of 24, and outcomes were of very low certainty of evidence. CONCLUSION: Although limited by heterogeneous observational studies, published reports of SCH indicate that most eyes with SCH experience some degree of VA improvement and anatomic success. However, final VA outcomes remain poor, with most cases resulting in severe visual impairment or blindness.

RESUMO

PURPOSE: To describe in detail the structural and functional phenotypes of a patient with cone-rod dystrophy associated with a full deletion of the NPHP1 gene. METHODS: A 30-year-old man with a history of end-stage renal disease presented with progressive vision loss in early adulthood prompting evaluation for retinal disease. Ophthalmic evaluation was performed including visual fields, electroretinography, spectral domain optical coherence tomography and short-wavelength and near-infrared fundus autofluorescence imaging. RESULTS: The visual acuity was 20/60 in each eye. Fundus examination revealed a subtle bull's-eye maculopathy confirmed with fundus autofluorescence. Spectral domain optical coherence tomography demonstrated perifoveal loss of the outer retinal layers with structural preservation further peripherally. Static perimetry confirmed the loss of cone greater than rod sensitivities in a manner that colocalized to structural findings. Electroretinography revealed decreased cone- and rod-mediated responses. Genetic testing confirmed a homozygous whole-gene deletion of the NPHP1 gene. CONCLUSION: NPHP1 -associated retinal degeneration may present as a cone-rod dystrophy in addition to the previously reported rod-predominant phenotypes and can notably be associated with systemic abnormalities, including renal disease. Our work further expands on the growing literature describing the retinal disease associated with systemic ciliopathies.

RESUMO

BACKGROUND: Chronic inflammatory demyelinating polyneuropathy (CIDP) is an acquired, immune-mediated, and clinically heterogeneous demyelinating disease affecting the nerve roots and peripheral nerves. We report a series of 4 patients who presented with early and progressive vision loss in the context of new-onset CIDP: 3 due to papilledema and 1 due to optic neuropathy without papilledema. METHODS: This was a retrospective case series of 4 patients with vision loss as a presenting feature of CIDP evaluated at the Hospital of the University of Pennsylvania from January 2016 to August 2021. Demographic, clinical, diagnostic, and treatment data were collected via retrospective medical record review. RESULTS: Case 1 was a 51-year-old man with 2 months of progressive bilateral papilledema associated with reduced visual acuity (count fingers at 1 foot in each eye) and severely constricted visual fields. Case 2 was a 36-year-old man with 4 months of worsening headaches, reduced visual acuity (count fingers at 1 foot in each eye), severely constricted visual fields, and papilledema. Case 3 was a 39-year-old man with papilledema causing progressive vision loss (20/80 in both eyes), headaches, and relapsing limb sensorimotor deficits. Case 4 was a 19-year-old man with 3 months of progressive bilateral visual decline (20/400 in the right eye, 20/600 in the left eye), central scotoma, and optic disc pallor consistent with optic neuropathy without papilledema. All 4 patients met clinical and electrodiagnostic criteria of CIDP. Cases 3 and 4 each tested positive for serum neurofascin-155 IgG4 antibodies. All patients were managed with immunomodulatory therapy. Cases 1 and 2 also each required surgical intervention with bilateral optic nerve sheath fenestration and cerebrospinal fluid (CSF) shunting procedures. CONCLUSION: Vision loss from optic neuropathy with or without papilledema has rarely been reported in CIDP, and typically has been described in the context of longstanding disease. Our cases highlight how CIDP can present with early vision loss that may be profound and challenging to manage if diagnosis is delayed. CIDP should be considered in any patient with new progressive vision loss when associated with peripheral sensorimotor symptoms and elevated CSF protein. The small subgroup of CIDP patients with neurofascin-155 antibodies may be at particular risk of optic nerve involvement.

RESUMO

Purpose: Ocular adverse events have been reported in association with dupilumab, a monoclonal antibody to treat allergic diseases including atopic dermatitis (AD). We describe clinical findings and treatment of dupilumab-related ocular complications. Patients and Methods: Retrospective study of 19 dupilumab-treated AD patients seen for a new ocular complaint. Primary outcomes were specific ocular exam findings (conjunctival injection, corneal fluorescein staining, blepharitis, meibomian gland dysfunction (MGD)), treatments, and follow-up. Results: Nineteen dupilumab-treated AD patients were included. Median age was 47 years (range 18-73). Over half were women (11/19) and majority were Caucasian (13/19). Symptom onset occurred at a mean of 99 days (range 23-520 days) from first dupilumab dose. The most common symptoms were redness (63%), tearing (47%), and pruritus (37%). Most common ocular findings were conjunctival injection (75%) and corneal staining (60%). Blepharitis was seen in about a third (30%), and 25% had MGD. Initially, 10% were observed without treatment, while 15% were treated with artificial tears alone. Other treatments included antihistamine drops (20%) and steroid drops alone (15%). In 40% of patients, a combination of steroids and various other topical eye drops were prescribed. Eighty-four percent (16/19) of patients were seen for follow-up. Steroid drops were required at follow-up in 3 out of 4 patients initially treated with antihistamines alone and in two-thirds of patients initially treated with artificial tears only. Mean follow-up period was 88 days (range 5-369). Dupilumab was discontinued in 31.5% (6/19) of patients; of those who discontinued, 3 restarted it later. Conclusion: Conjunctival injection was the most frequent dupilumab-related ocular symptom and most common exam finding followed by corneal staining. Most patients initially treated with antihistamine drops or artificial tears alone subsequently required steroid drops to control symptoms. Some patients who discontinued dupilumab restarted the medication after achieving adequate control of ocular symptoms.

RESUMO

PURPOSE: To determine frequency of hypercoagulability testing and hypercoagulable states in patients with central retinal vein occlusion (CRVO) younger than 50 years. DESIGN: Retrospective cohort study. PARTICIPANTS: Deidentified patients younger than 50 years with newly diagnosed CRVO from a national insurance claims database. METHODS: The de-identified Clinformatics Data Mart Database (Optum) containing medical claims from a commercial and Medicare Advantage insurance database was used. All outpatient medical claims (office visits, associated diagnoses, and laboratory testing) and demographic data for each beneficiary during their enrollment were accessible. MAIN OUTCOME MEASURES: Prevalence of (1) laboratory hypercoagulable workup within 90 days of CRVO diagnosis, (2) new diagnosis of a hypercoagulable state within 1 year of CRVO diagnosis, and (3) diagnosis of hypertension, diabetes mellitus (DM), and hyperlipidemia. RESULTS: One thousand one hundred eighty-one patients met inclusion criteria. Six hundred seventy-one patients (56.8%) were men, 450 patients (38.1%) had undergone hypercoagulable testing within 90 days, and 136 patients (11.5%) were diagnosed with a hypercoagulable state within 1 year after CRVO diagnosis. This proportion was similar between those patients with DM, hypertension, or hyperlipidemia (10.5% [65/620]) and those without (12.7% [71/561]; P = 0.28). Of the 136 patients diagnosed with a hypercoagulability state, 68.4% (93/136) had undergone testing within 90 days of CRVO diagnosis and 31.6% (43/136) did not. Of those who had not undergone hypercoagulability testing, 5.9% (43/731) were diagnosed with a hypercoagulable state within 1 year compared with 20.7% (93/450) in those who were tested (P < 0.001). CONCLUSIONS: The prevalence of a hypercoagulable state within 1 year of CRVO diagnosis in patients younger than 50 years was 11.5%, and the prevalence was similar between patients with atherosclerotic risk factors and those without. Rate of testing was only 38.1%. Future research should examine the usefulness of uniform hypercoagulable testing in young CRVO patients.

RESUMO

We report the case of a 14-year-old boy with history of microangiopathic hemolytic crises secondary to atypical hemolytic uremic syndrome presenting with new-onset decreased vision, flashes, and floaters in his left eye. The patient had a history of chronic retinal detachment in the right eye and retinal neovascularization in the left eye treated with panretinal photocoagulation at age 5. He was now found to have a new combined tractional-rhegmatogenous retinal detachment in the left eye. Despite surgical reattachment of the retina, he had progressive retinal and optic nerve ischemia, with resultant left eye visual acuity of light perception. To our knowledge, this is the first reported case of proliferative retinopathy and tractional and rhegmatogenous retinal detachments in a pediatric patient with atypical hemolytic uremic syndrome.

RESUMO

PURPOSE: To perform a comprehensive analysis of characteristics of ophthalmology trials registered in ClinicalTrials.gov. DESIGN: Cross-sectional study. METHODS: All 4,203 ophthalmologic clinical trials registered on ClinicalTrials.gov between October 1, 2007, and April 30, 2018, were identified by using medical subject headings (MeSH). Disease condition terms were verified by manual review. Trial characteristics were assessed through frequency calculations. Hazard ratios and 95% confidence intervals were determined for characteristics associated with early discontinuation. RESULTS: The majority of trials were multiarmed (73.6%), single-site (69.4%), randomized (64.8%), and had <100 enrollees (66.3%). A total of 33% used a data-monitoring committee (DMC), and 50.6% incorporated blinding. Other groups (51.6%) were funded by industry, whereas 2.6% were funded by the US National Institutes of Health (NIH). NIH trials were significantly more likely to address oncologic (NIH = 15.5%, Other = 3%, Industry = 1.5%; P < 0.001) or pediatric disease (NIH = 20.9%, Other = 5.9%, Industry = 1.4%; P < 0.001). Industry-sponsored trials (69.6% of phase 3 trials) were significantly more likely to be randomized (Industry = 68.7%, NIH = 58.9%, Other = 60.8%; P < 0.001) and blinded (Industry = 57.2%, NIH = 42.7%, Other = 43.5%; P < 0.001). A total of 359 trials (8.5%) were discontinued early, and 530 trials (12.6%) had unknown status. Trials were less likely to be discontinued if funded by sources other than industry (hazard ratio [HR], 0.72; 95% confidence interval [CI], 0.55-0.95; P = 0.021) and/or had a DMC (HR, 0.71; 95% CI, 0.55-0.92; P = 0.010). CONCLUSIONS: Ophthalmology trials in the past decade reveal heterogeneity across study funding sources. NIH trials were more likely to support historically underfunded subspecialties, whereas Industry trials were more likely to face early discontinuation. These trends emphasize the importance of carefully monitored and methodologically sound trials with deliberate funding allocation.

RESUMO

PURPOSE: To compare the rates of infectious endophthalmitis following intravitreal injection of ranibizumab using prefilled syringes vs conventional preparation. DESIGN: Multicenter retrospective cohort study. METHODS: All eyes receiving intravitreal injection of 0.5 mg ranibizumab for retinal vascular diseases at 10 retina practices across the United States (2016 to 2017) and Japan (2009 to 2017) were included. The total numbers of eyes and injections were determined from billing codes. Endophthalmitis cases were determined from billing records and evaluated with chart review. Primary outcome was the rate of postinjection acute endophthalmitis. Secondary outcomes were visual acuity and microbial spectrum. RESULTS: A total of 243 754 intravitreal 0.5 mg ranibizumab injections (165 347 conventional and 78 407 prefilled) were administered to 43 132 unique patients during the study period. In the conventional ranibizumab group, a total of 43 cases of suspected endophthalmitis occurred (0.026%; 1 in 3845 injections) and 22 cases of culture-positive endophthalmitis occurred (0.013%; 1 in 7516 injections). In the prefilled ranibizumab group, 12 cases of suspected endophthalmitis occurred (0.015%; 1 in 6534 injections) and 2 cases of culture-positive endophthalmitis occurred (0.0026%; 1 in 39 204 injections). Prefilled syringes were associated with a trend toward decreased risk of suspected endophthalmitis (odds ratio 0.59; 95% confidence interval 0.31-1.12; P = .10) and a statistically significant decreased risk of culture-positive endophthalmitis (odds ratio 0.19; 95% confidence interval 0.045-0.82; P = .025). Average logMAR vision loss at final follow-up was significantly worse for eyes that developed endophthalmitis from the conventional ranibizumab preparation compared to the prefilled syringe group (4.45 lines lost from baseline acuity vs 0.38 lines lost; P = .0062). Oral-associated flora was found in 27.3% (6/22) of conventional ranibizumab culture-positive endophthalmitis cases (3 cases of Streptococcus viridans, 3 cases of Enterococcus faecalis) compared to 0 cases in the prefilled ranibizumab group. CONCLUSION: In a large, multicenter, retrospective study the use of prefilled syringes during intravitreal injection of ranibizumab was associated with a reduced rate of culture-positive endophthalmitis, including from oral flora, as well as with improved visual acuity outcomes.

RESUMO

PURPOSE OF REVIEW: To review how the media frames obesity and the effect it has upon on public perceptions. RECENT FINDINGS: The scientific and public health understanding of obesity increasingly points away from individual behaviors and toward medical and community factors, but diffusion of this knowledge is slow. Growing awareness of the importance of body positivity is driving attention to the harms of weight bias and fat shaming. Health science reporting related to obesity, nutrition, and physical activity tends to perpetuate myths and misunderstandings. Moving forward, greater attention to accurate messages about obesity and evidence-based interventions will be essential for progress to reduce suffering and the impact on public health from this chronic disease.

RESUMO

Familial exudative vitreoretinopathy (FEVR) is a heritable vitreoretinopathy characterized by anomalous retinal vascular development. The principal feature of the disease is an avascular peripheral retina. This in turn can cause further pathological changes including neovascularization, exudation, hemorrhage, and retinal detachment. The biological basis of the disease is thought to be from defects in the Wnt signaling pathway. Many gene mutations have been implicated, and these can be inherited in an autosomal dominant (most common), autosomal recessive, and X-linked recessive fashion. Examination with wide-field fluorescein angiography is essential and can identify the disease in its earlier stages, enabling timely treatment, in addition to helping identify asymptomatic family members. The current treatment paradigm involves laser photocoagulation of the avascular peripheral retina for neovascular sequelae and vitreoretinal surgery for progressive retinal detachment. Further studies are underway to better characterize this complex vitreoretinopathy.

RESUMO

PURPOSE: To present 2 patients in whom orbital radiation preceded the development of periorbital extranodal marginal zone lymphoma by more than a decade and to investigate the likelihood of this representing irradiation-induced malignancy. METHODS: Retrospective chart review and histopathologic study with immunohistochemistry of 2 cases. RESULTS: The first patient was a 58-year-old woman who developed an orbital mass within the vicinity of the lateral rectus muscle 17 years after external beam proton radiation therapy for an inferotemporal choroidal melanoma. The second patient was a 32-year-old woman who developed a mass in the right lacrimal gland 12 years after external beam photon radiation therapy for chronic inflammatory dacryoadenitis. Histopathologic and immunohistochemical studies confirmed orbital extranodal marginal zone lymphoma in both cases. Retrospective review of older histopathologic slides from the second patient revealed underlying immunoglobulin G4-related disease. DISCUSSION: The unusual sequence of events in these 2 cases raises the question of whether orbital radiation may in rare instances promote the development of orbital extranodal marginal zone lymphoma. The literature pertaining to irradiation-induced secondary malignancy in the orbit is reviewed. CONCLUSIONS: Clinicians should consider the possibility of a secondary malignancy when evaluating a patient with an orbital mass and a history of prior local radiation exposure.

RESUMO

As a leading cause of morbidity and mortality in the United States and worldwide, obesity is a disease that is frequently encountered in clinical practice today and requires a range of medical interventions. While obesity affects both men and women across all ages, multiple issues are particularly germane to women's health, particularly as obesity is more prevalent among women than men in the United States and obesity among women of reproductive health relates to the growing issue of childhood obesity. Discussed herein are the epidemiology and pathophysiology of obesity along with the impact of perinatal obesity on fetal programming. Guidance on screening and management of obesity through lifestyle intervention, pharmacologic therapy, and bariatric surgery, as well as avoidance of weight-promoting medications wherever possible, is elaborated. Particular attention is paid to the contribution of these modalities to weight loss as well as their impact on obesity-related comorbidities that affect a woman's overall health, such as type 2 diabetes and hypertension, and her reproductive and gynecologic health. With modest weight loss, women with obesity can achieve notable improvements in chronic medical conditions, fertility, pregnancy outcomes, and symptoms of pelvic floor disorders. Moreover, as children born to women after bariatric surgery-induced weight loss show improved metabolic outcomes, this demonstrates a role for maternal weight loss in reducing risk of development of metabolic disturbances in children. In light of the immense cost burden and mortality from obesity, it is important to emphasize the role of lifestyle intervention, pharmacologic management, and bariatric surgery for weight loss in clinical practice to mitigate the impact of obesity on women's health.

RESUMO

BACKGROUND: Autism is a neurodevelopmental disorder characterized by impairments in social interaction, verbal communication and repetitive behaviors. To date the etiology of this disorder is poorly understood. Studies suggest that astrocytes play critical roles in neural plasticity by detecting neuronal activity and modulating neuronal networks. Recently, a number of studies suggested that an abnormal function of glia/astrocytes may be involved in the development of autism. However, there is yet no direct evidence showing how astrocytes develop in the brain of autistic individuals. METHODS: Study subjects include brain tissue from autistic subjects, BTBR T + tfJ (BTBR) and Neuroligin (NL)-3 knock-down mice. Western blot analysis, Immunohistochemistry and confocal microscopy studies have be used to examine the density and morphology of astrocytes, as well as Wnt and ß-catenin protein expression. RESULTS: In this study, we demonstrate that the astrocytes in autisitcsubjects exhibit significantly reduced branching processes, total branching length and cell body sizes. We also detected an astrocytosis in the frontal cortex of autistic subjects. In addition, we found that the astrocytes in the brain of an NL3 knockdown mouse exhibited similar alterations to what we found in the autistic brain. Furthermore, we detected that both Wnt and ß-catenin proteins are decreased in the frontal cortex of autistic subjects. Wnt/ß-catenin pathway has been suggested to be involved in the regulation of astrocyte development. CONCLUSIONS: Our findings imply that defects in astrocytes could impair neuronal plasticity and partially contribute to the development of autistic-like behaviors in both humans and mice. The alteration of Wnt/ß-catenin pathway in the brain of autistic subjects may contribute to the changes of astrocytes.

RESUMO

Autism is a neurodevelopmental disorder characterized by problems in communication, social skills, and repetitive behavior. Recent studies suggest that apoptotic and inflammatory mechanisms may contribute to the pathogenesis of this disorder. Nuclear factor-κB (NF-κB) is an important gene transcriptional factor involved in the mediation of inflammation and apoptosis. This study examined the activities of the NF-κB signaling pathway in the brain of autistic subjects and their age-matched controls. The NF-κB activation is also determined in the brain of BTBR mice, which is a promising animal model for study of pathogenic mechanisms responsible for autism. Our results showed that the level of IKKα kinase, which phosphorylates the inhibitory subunit IκBα, is significantly increased in the cerebellum of autistic subjects. However, the expression and phosphorylation of IκBα are not altered. In addition, our results demonstrated that the expression of NF-κB (p65), and the phosphorylation/activation of NF-κB (p65) at Ser536 are not significantly changed in the cerebellum and cortex of both autistic subjects and BTBR mice. Our findings suggest that the NF-κB signaling pathway is not disregulated in the brain of autistic subjects and thus may not be significantly involved in the processes of abnormal inflammatory responses suggested in autistic brain.
