Long-Term Decrease in Intraocular Pressure in Survivors of Ebola Virus Disease in the Partnership for Research on Vaccines and Infectious Diseases in Liberia (PREVAIL) III Study.

Objective: Survivors of Ebola virus disease (EVD) experience decreased intraocular pressure (IOP) relative to unaffected close contacts during the first year of convalescence. Whether this effect persists over time and its relationship to intraocular pathology are unclear. We sought to determine whether IOP remained lower in survivors of EVD over 4 years of follow-up and to identify associated risk factors. Design: Partnership for Research on Vaccines and Infectious Diseases in Liberia (PREVAIL) III is a 5-year, longitudinal cohort study of survivors of EVD and their close contacts and is a collaboration between the Liberian Ministry of Health and the United States National Institutes of Health. Participants: Participants who enrolled in PREVAIL III at John F. Kennedy Medical Center in Liberia, West Africa from June 2015 to March 2016 who underwent comprehensive ophthalmic evaluation annually for 5 consecutive visits. Methods: Intraocular pressure was measured at each visit by a handheld rebound tonometer using sterile tips. Comparisons are made between antibody-positive survivors and antibody-negative close contacts. Main Outcome Measures: Intraocular pressure, measured in mmHg, at each study visit. Results: Of 565 antibody-positive survivors and 644 antibody-negative close contacts enrolled in the study at baseline, the majority of participants returned annually, with 383 (67.8%) and 407 (63.2%) participants, respectively, presenting for the final study visit at a median of 60 months after symptom onset. A sustained, relative decrease in IOP was observed in survivors relative to close contacts, with mean difference of -0.72 mmHg (95% confidence interval [CI] -1.18 to -0.27) at the final study visit. This difference remained constant throughout the study period (P = 0.4 for interaction over time). Among survivors, physical examination findings of vitreous cell and OCT findings of vitreous opacities both demonstrated a significant association with decreased IOP at baseline (P < 0.05 for both). After adjusting for such factors, the difference throughout the follow-up (-0.93 mmHg, 95% CI, -1.23 to -0.63) remained significant. Conclusions: Survivors of EVD experienced a sustained decrease in IOP relative to close contacts over a 5-year period after EVD. The results highlight the importance of considering long-term sequelae of emerging infectious diseases within a population.

Ocular surface indicators and biomarkers in chronic ocular graft-versus-host disease: a prospective cohort study.

This longitudinal cohort study compared ocular surface indicators in forty allogeneic hematopoietic stem cell transplant (HSCT) subjects with twenty healthy controls at baseline and identified changes in ocular graft-versus-host disease (oGVHD). Outcome measures included: Ocular Surface Disease Index (OSDI), tear osmolarity, Schirmer's test, Oxford corneal staining score, tear break-up time (TBUT), and tear and serum biomarkers (IFN-γ, IL-10, MMP-9, IL-12, IL-13, IL-17α, IL-1ß, IL-2, IL-4, IL-6, IL-8, CXCL10, MCP-1, MIP-1α, RANTES, TNF-α). At baseline the HSCT group had higher median Oxford corneal staining score (1.7 vs. 0.0; P < 0.0001), higher tear TNF-α (20.0 vs. 11.2 pg/mL; P < 0.0001), lower tear RANTES (70.4 vs. 190.2 pg/mL; P < 0.0001), higher serum IL-8 (10.2 vs. 4.5 pg/mL; P = 0.0008), and higher serum TNF-α (8.7 vs. 4.2 pg/mL; P < 0.0001). The incidence of oGVHD was 62% and associated changes included increased Oxford corneal staining score (4.6 vs. 1.8, P = 0.0001), decreased Schirmer's test (3.0 vs. 10.0; P < 0.0001), and decreased TBUT (4.7 vs. 9.0 s; P = 0.0004). Baseline differences in ocular surface indicators suggest a tendency toward ocular dryness in individuals with hematologic disorders preparing for HSCT. Individuals who developed oGVHD showed changes in corneal staining score, Schirmer's test, and TBUT.

Efficacy and Safety Outcomes of Cataract Surgery in Survivors of Ebola Virus Disease: 12-Month Results From the PREVAIL VII Study.

Purpose: In survivors of Ebola virus disease (EVD), intraocular viral persistence raises questions about the timing and safety of cataract surgery. To the best of our knowledge, this is the first controlled study evaluating Ebola virus persistence and cataract surgery safety and outcomes in EVD survivors. Methods: Seropositive EVD survivors and seronegative controls with vision worse than 20/40 from cataract and without active intraocular inflammation were enrolled. Aqueous humor from survivors was tested with reverse transcription-polymerase chain reaction for Ebola viral RNA. Participants underwent manual small-incision cataract surgery and 1 year of follow-up examinations. Results: Twenty-two eyes of 22 survivors and 12 eyes of eight controls underwent cataract surgery. All of the aqueous samples tested negative for Ebola viral RNA. Median visual acuity improved from 20/200 at baseline to 20/25 at 1 year in survivors and from count fingers to 20/50 in controls (overall, P < 0.001; between groups, P = 0.07). After a 1-month course of topical corticosteroids, 55% of survivors and 67% of controls demonstrated at least 1+ anterior chamber cell. Twelve months after surgery, optical coherence tomography revealed a median increase in macular central subfield thickness of 42 µm compared with baseline (overall, P = 0.029; between groups, P = 0.995). Conclusions: EVD survivors and controls demonstrated significant visual improvement from cataract surgery. The persistence of intraocular inflammation highlights the importance of follow-up. The absence of detectable intraocular Ebola viral RNA provides guidance regarding the safety of eye surgery in Ebola survivors. Translational Relevance: These findings demonstrate the safety and efficacy of cataract surgery in Ebola survivors and will inform ocular surgery guidelines in this population.

Characterization of Ebola Virus-Associated Eye Disease.

Importance: Survivors of Ebola virus disease (EVD) may experience ocular sequelae. Comparison with antibody-negative individuals from the local population is required to characterize the disease. Objective: To assess features of ophthalmic disease specific to EVD. Design, Setting, and Participants: This baseline cross-sectional analysis of survivors of EVD and their close contacts was conducted within PREVAIL III, a 5-year, longitudinal cohort study. Participants who enrolled at John F. Kennedy Medical Center in Liberia, West Africa from June 2015 to March 2016 were included in this analysis. Close contacts were defined as household members or sex partners of survivors of EVD. Data were analyzed from July 2016 to July 2020. Exposures: All participants, both survivors and close contacts, underwent testing of IgG antibody levels against Ebola virus surface glycoprotein. Main Outcomes and Measures: Ocular symptoms, anterior and posterior ophthalmologic examination findings, and optical coherence tomography images were compared between antibody-positive survivors and antibody-negative close contacts. Results: A total of 564 antibody-positive survivors (320 [56.7%] female; mean [SD] age, 30.3 [14.0] years) and 635 antibody-negative close contacts (347 [54.6%] female; mean [SD] age, 25.8 [15.5] years) were enrolled in this study. Survivors were more likely to demonstrate color vision deficit (28.9% vs 19.0%, odds ratio [OR], 1.6; 95% CI, 1.2-2.1) and lower intraocular pressure (12.4 vs 13.5 mm Hg; mean difference, -1.2 mm Hg; 95% CI, -1.6 to -0.8 mm Hg) compared with close contacts. Dilated fundus examination revealed a higher percentage of vitreous cells (7.8% vs 0.5%; OR, 16.6; 95% CI, 5.0-55.2) and macular scars (4.6% vs 1.6%; OR, 2.8; 95% CI, 1.4-5.5) in survivors than in close contacts. Uveitis was present in 26.4% of survivors and 12.1% of close contacts (OR, 2.4; 95% CI, 1.8-3.2). Among all participants with uveitis, survivors were more likely than close contacts to have intermediate uveitis (34.2% vs 6.5% of all cases; OR, 7.8; 95% CI, 3.1-19.7) and had thicker mean central subfield thickness on optical coherence tomography (222 vs 212 µm; mean difference, 14.4 µm; 95% CI, 1.9-26.9 µm). Conclusions and Relevance: In this cross-sectional study, survivors of EVD had a distinct spectrum of ocular and neuro-ophthalmologic findings compared with close contacts that potentially require medical and surgical treatment.

Corneal thinning and cornea guttata in patients with mutations in TGFB2.

OBJECTIVE: Human genome-wide association studies and animal models suggest a role for TGFB2 in contributing to the corneal thickness phenotype. No specific mutations, however, have been reported in this gene that affect corneal thickness. We sought to determine if haploinsufficiency of TGFB2 in humans associated with Loeys-Dietz syndrome type 4 is associated with corneal thinning. DESIGN: Observational cohort study of families with Loeys-Dietz syndrome type 4, caused specifically by TGFB2 mutations, in a tertiary care setting. PARTICIPANTS: Three probands with pathogenic mutations in TGFB2 and family members underwent comprehensive ophthalmic examination. METHODS: Clinical assessment included Scheimpflug imaging, specular microscopy, and slit-lamp biomicroscopy. We measured visual acuity, axial length, refractive error, and central corneal thickness. RESULTS: Clinical evaluation of 2 probands identified corneal thinning and cornea guttata, despite a young age and distinct mutations in TGFB2 (c.905G>A, p.Arg302His; c.988C>A, p.Arg330Ser). In the third family, corneal thinning co-segregated with a TGFB2 mutation (c.1103G>A, p.Gly368Glu), although without apparent guttae. CONCLUSIONS: In this series, participants with TGFB2 mutations associated with Loeys-Dietz syndrome type 4 demonstrated decreased corneal thickness, and in 2 cases with splice site mutations, also demonstrated cornea guttata. The data demonstrate the importance of considering distinct phenotype-genotype correlations within this condition.

A Longitudinal Study of Ebola Sequelae in Liberia.

BACKGROUND: Multiple health problems have been reported in survivors of Ebola virus disease (EVD). Attribution of these problems to the disease without a control group for analysis is difficult. METHODS: We enrolled a cohort of EVD survivors and their close contacts and prospectively collected data on symptoms, physical examination findings, and laboratory results. A subset of participants underwent ophthalmologic examinations. Persistence of Ebola virus (EBOV) RNA in semen samples from survivors was determined. RESULTS: A total of 966 EBOV antibody-positive survivors and 2350 antibody-negative close contacts (controls) were enrolled, and 90% of these participants were followed for 12 months. At enrollment (median time to baseline visit, 358 days after symptom onset), six symptoms were reported significantly more often among survivors than among controls: urinary frequency (14.7% vs. 3.4%), headache (47.6% vs. 35.6%), fatigue (18.4% vs. 6.3%), muscle pain (23.1% vs. 10.1%), memory loss (29.2% vs. 4.8%), and joint pain (47.5% vs. 17.5%). On examination, more survivors than controls had abnormal abdominal, chest, neurologic, and musculoskeletal findings and uveitis. Other than uveitis (prevalence at enrollment, 26.4% vs. 12.1%; at year 1, 33.3% vs. 15.4%), the prevalence of these conditions declined during follow-up in both groups. The incidence of most symptoms, neurologic findings, and uveitis was greater among survivors than among controls. EBOV RNA was detected in semen samples from 30% of the survivors tested, with a maximum time from illness to detection of 40 months. CONCLUSIONS: A relatively high burden of symptoms was seen in all participants, but certain symptoms and examination findings were more common among survivors. With the exception of uveitis, these conditions declined in prevalence during follow-up in both groups. Viral RNA in semen persisted for a maximum of 40 months.

Ocular Inflammatory Disorders in Autoimmune Lymphoproliferative Syndrome (ALPS).

PURPOSE: To describe inflammatory ocular findings in patients with autoimmune lymphoproliferative syndrome (ALPS). METHODS: A retrospective review of medical records for ALPS patients seen at the National Eye Institute between 2003 and 2013. RESULTS: A total of 29 ALPS patients previously referred for ocular or visual symptoms or with a history of prolonged corticosteroid use, were identified. Mean age was 20 years (range: 4-66 years). The majority were male (n = 21, 72.4%) and Caucasian (n = 24, 82.8%). Ten (34.5%) had abnormal ocular findings, the most common of which was an ocular inflammatory disorder (n = 4, 13.8%). Uveitis was seen in two patients with ALPS-FAS and one with ALPS-U, all of whom required long-term systemic immunosuppression. One patient with ALPS-FAS had a history of optic neuritis. CONCLUSIONS: ALPS can have intraocular inflammatory manifestations that require routine follow-up to ensure appropriate and timely treatment of intraocular disease. Long-term immunosuppression may be needed for patients with ALPS-associated uveitis.

Redefined clinical features and diagnostic criteria in autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy.

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare primary immunodeficiency disorder typically caused by homozygous AIRE mutations. It classically presents with chronic mucocutaneous candidiasis and autoimmunity that primarily targets endocrine tissues; hypoparathyroidism and adrenal insufficiency are most common. Developing any two of these classic triad manifestations establishes the diagnosis. Although widely recognized in Europe, where nonendocrine autoimmune manifestations are uncommon, APECED is less defined in patients from the Western Hemisphere. We enrolled 35 consecutive American APECED patients (33 from the US) in a prospective observational natural history study and systematically examined their genetic, clinical, autoantibody, and immunological characteristics. Most patients were compound heterozygous; the most common AIRE mutation was c.967_979del13. All but one patient had anti-IFN-ω autoantibodies, including 4 of 5 patients without biallelic AIRE mutations. Urticarial eruption, hepatitis, gastritis, intestinal dysfunction, pneumonitis, and Sjögren's-like syndrome, uncommon entities in European APECED cohorts, affected 40%-80% of American cases. Development of a classic diagnostic dyad was delayed at mean 7.38 years. Eighty percent of patients developed a median of 3 non-triad manifestations before a diagnostic dyad. Only 20% of patients had their first two manifestations among the classic triad. Urticarial eruption, intestinal dysfunction, and enamel hypoplasia were prominent among early manifestations. Patients exhibited expanded peripheral CD4+ T cells and CD21loCD38lo B lymphocytes. In summary, American APECED patients develop a diverse syndrome, with dramatic enrichment in organ-specific nonendocrine manifestations starting early in life, compared with European patients. Incorporation of these new manifestations into American diagnostic criteria would accelerate diagnosis by approximately 4 years and potentially prevent life-threatening endocrine complications.

Predictive models for ocular chronic graft-versus-host disease diagnosis and disease activity in transplant clinical practice.

Ocular chronic graft-versus-host disease is one of the most bothersome common complications following allogeneic hematopoietic stem cell transplantation. The National Institutes of Health Chronic Graft-versus-Host Disease Consensus Project provided expert recommendations for diagnosis and organ severity scoring. However, ocular chronic graft-versus-host disease can be diagnosed only after examination by an ophthalmologist. There are no currently accepted definitions of ocular chronic graft-versus-host disease activity. The goal of this study was to identify predictive models of diagnosis and activity for use in clinical transplant practice. A total of 210 patients with moderate or severe chronic graft-versus-host disease were enrolled in a prospective, cross-sectional, observational study (clinicaltrials.gov identifier: 00092235). Experienced ophthalmologists determined presence of ocular chronic graft-versus-host disease, diagnosis and activity. Measures gathered by the transplant clinician included Schirmer's tear test and National Institutes of Health 0-3 Eye Score. Patient-reported outcome measures were the ocular subscale of the Lee Chronic Graft-versus-Host Disease Symptom Scale and Chief Eye Symptom Intensity Score. Altogether, 157 (75%) patients were diagnosed with ocular chronic graft-versus-host disease; 133 of 157 patients (85%) had active disease. In a multivariable model, the National Institutes of Health Eye Score (P<0.0001) and Schirmer's tear test (P<0.0001) were independent predictors of ocular chronic graft-versus-host disease (sensitivity 93.0%, specificity 92.2%). The Lee ocular subscale was the strongest predictor of active ocular chronic graft-versus-host disease (P<0.0001) (sensitivity 68.5%, specificity 82.6%). Ophthalmology specialist measures that were most strongly predictive of diagnosis in a multivariate model were Oxford grand total staining (P<0.0001) and meibomian score (P=0.027). These results support the use of selected transplant clinician- and patient-reported outcome measures for ocular chronic graft-versus-host disease screening when providing care to allogeneic hematopoietic stem cell transplantation survivors with moderate to severe chronic graft-versus-host disease. Prospective studies are needed to determine if the Lee ocular subscale demonstrates adequate responsiveness as a disease activity outcome measure.

Molecular identification of bacterial DNA in the chorioretinal scars of chronic granulomatous disease.

PURPOSE: Chronic granulomatous disease (CGD) is an inherited disorder characterized by defects in phagocyte-derived nicotinamide adenine dinucleotide phosphate oxidase. It is typically diagnosed in childhood and leads to severe, recurrent bacterial or fungal infections. Chorioretinal lesions are the most common ocular manifestation. We sought to determine whether there are infectious agents in CGD-associated chorioretinopathy. METHODS: Medical records and ocular histopathology from CGD cases from January 1983 to January 2012 at the National Institutes of Health were retrospectively reviewed. Chorioretinal cells from normal and lesional tissues of the same eye were microdissected. Primers for Staphylococcus epidermidis, Staphylococcus aureus, Pseudomonas aeruginosa, Burkholderia sp., and a panbacterial 16S ribosomal DNA were used for polymerase chain reaction. RESULTS: Seventeen CGD patients had ocular tissues (16 autopsied cases and 1 chorioretinal biopsy) examined. Of these 17, 8 demonstrated CGD-associated chorioretinal lesions in at least one eye on histopathology. Of these 8, 7 showed amplification of 16S ribosomal DNA within the lesion; of these 7, two also amplified S. epidermidis and one P. aeruginosa. One had no bacterial DNA amplified. Importantly, no microbial DNA was amplified from the normal, non-lesional ocular tissues of these 8 cases. Furthermore, only 1 of the 9 eyes without chorioretinopathy had amplified Burkholderia DNA, that patient had a history of Burkholderia infection. CONCLUSIONS: We detected bacterial DNA in 7 of 8 (88%) cases with CGD-associated chorioretinopathy and only in 1 normal ocular tissue of 17 CGD cases. Bacterial infection may play a role in the pathogenesis of CGD-associated chorioretinal lesions.

Ocular manifestations of xeroderma pigmentosum: long-term follow-up highlights the role of DNA repair in protection from sun damage.

OBJECTIVE: Xeroderma pigmentosum (XP) is a rare autosomal recessive disease caused by mutations in DNA repair genes. Clinical manifestations of XP include mild to extreme sensitivity to ultraviolet radiation resulting in inflammation and neoplasia in sun-exposed areas of the skin, mucous membranes, and ocular surfaces. This report describes the ocular manifestations of XP in patients systematically evaluated in the Clinical Center at the National Institutes of Health. DESIGN: Retrospective observational case series. PARTICIPANTS: Eighty-seven participants, aged 1.3 to 63.4 years, referred to the National Eye Institute (NEI) for examination from 1964 to 2011. Eighty-three patients had XP, 3 patients had XP/Cockayne syndrome complex, and 1 patient had XP/trichothiodystrophy complex. METHODS: Complete age- and developmental stage-appropriate ophthalmic examination. MAIN OUTCOME MEASURES: Visual acuity; eyelid, ocular surface, and lens pathology; tear film and tear production measures; and cytologic analysis of conjunctival surface swabs. RESULTS: Of the 87 patients, 91% had at least 1 ocular abnormality. The most common abnormalities were conjunctivitis (51%), corneal neovascularization (44%), dry eye (38%), corneal scarring (26%), ectropion (25%), blepharitis (23%), conjunctival melanosis (20%), and cataracts (14%). Thirteen percent of patients had some degree of visual axis impingement, and 5% of patients had no light perception in 1 or both eyes. Ocular surface cancer or a history of ocular surface cancer was present in 10% of patients. Patients with an acute sunburning skin phenotype were less likely to develop conjunctival melanosis and ectropion but more likely to develop neoplastic ocular surface lesions than nonburning patients. Some patients also showed signs of limbal stem cell deficiency. CONCLUSIONS: Our longitudinal study reports the ocular status of the largest group of patients with XP systematically examined at 1 facility over an extended period of time. Structural eyelid abnormalities, neoplasms of the ocular surface and eyelids, tear film and tear production abnormalities, ocular surface disease and inflammation, and corneal abnormalities were present in this population. Burning and nonburning patients with XP exhibit different rates of important ophthalmologic findings, including neoplasia. In addition, ophthalmic characteristics can help refine diagnoses in the case of XP complex phenotypes. DNA repair plays a major role in protection of the eye from sunlight-induced damage.

Rifabutin-associated hypopyon uveitis and retinal vasculitis with a history of acute myeloid leukemia.

PURPOSE: This study reports a case of bilateral rifabutin-associated uveitis in a child with a history of acute myeloid leukemia. METHODS: We utilized a clinical case description and brief discussion. RESULTS: A 17-year-old girl presented with acute bilateral anterior uveitis, a hypopyon in the left eye, and moderate bilateral vitritis. She had a history of acute myeloid leukemia status post-allogeneic hematopoietic stem cell transplant 5 years earlier. She was receiving rifabutin for a biopsy-proven Mycobacterium avium complex pulmonary infection. Work up for infectious and neoplastic etiologies was negative. The uveitis initially responded to topical corticosteroids, but recurred when the drops were tapered. Fluorescein angiography demonstrated diffuse vasculitis of small retinal vessels and cystoid macular edema. After rifabutin was discontinued, the uveitis and vasculitis slowly resolved. CONCLUSION: Fluorescein angiography demonstrated widespread retinal vasculitis which is a rare manifestation of rifabutin-associated uveitis.

Posterior segment ophthalmic complications of aplastic anemia.

Three patients with aplastic anemia were evaluated by the ophthalmology service within 2 months of the aplastic anemia diagnosis for bilateral visual loss. The mean age of diagnosis of aplastic anemia was 14.3 years (range: 5 to 19 years) and the mean follow-up was 25 months (range: 15 to 44 months). All 6 eyes demonstrated choroidal ischemia and vitreous hemorrhage. Pars plana vitrectomy was performed in four eyes of two patients for non-clearing vitreous hemorrhage; one patient was observed. Successful anatomic outcomes were achieved in 3 of 4 eyes that underwent vitrectomy. Initial visual acuity ranged from 20/80 to bare light perception and final visual acuity ranged from 20/20 to no light perception. All patients received immunosuppressive therapy including cyclosporine and anti-thymocyte globulin, and two underwent hematopoietic stem cell transplantation. All patients received perioperative platelet and blood transfusions. Pars plana vitrectomy resulted in functional and anatomic success in the majority of eyes in this series. Coordination of medical and surgical care with the hematology service is advisable to stabilize hematologic parameters prior to undertaking a vitreoretinal procedure.

Salivary gland involvement in chronic graft-versus-host disease: prevalence, clinical significance, and recommendations for evaluation.

Although xerostomia is a commonly reported complaint in patients with chronic graft-versus-host disease (cGVHD), criteria for evaluating the prevalence and characteristics of salivary gland involvement have not been well defined in this patient population. Previous studies also have made no distinction between salivary and mucosal oral cGVHD. We systematically evaluated signs and symptoms of sicca in a large cohort of patients with cGVHD (n = 101) using instruments widely used to study Sjogren's syndrome. Xerostomia was reported in 60 (77%) patients reporting ocular and 52 (67%) patients reporting oral complaints [corrected]. The salivary flow rate was < or =0.2 mL/min in 27%, and < or =0.1 mL/min in 16%. Histopathological changes, consisting of mononuclear infiltration and/or fibrosis/atrophy, were present in all patients with salivary dysfunction. Importantly, there was no correlation of salivary and oral mucosal involvement in cGVHD. Patients with cGVHD-associated salivary gland involvement had diminished oral cavity-specific quality of life and lower body mass index. Salivary gland involvement is a common and clinically distinct manifestation of cGVHD. Formal evaluation of salivary function using standardized criteria is needed, and this could be incorporated as an outcome measure in clinical trials of cGVHD.
