Pediatric herpes zoster ophthalmicus: a systematic review.

PURPOSE: While typically affecting older adults and immunocompromised individuals, herpes zoster ophthalmicus (HZO) has been reported with varying manifestations and complications in children. In this review, we evaluate reported cases of pediatric HZO in the literature and discuss the epidemiology, risk factors, clinical presentation, treatment and outcomes. METHODS: A literature search on PubMed, Scopus, and Web of Science databases was performed using the terms "pediatric herpes zoster ophthalmicus" and "herpes zoster ophthalmicus children." Publications that were not specific to HZO or pediatric populations were excluded, as were publications that were not available to review or not published in the English language. RESULTS: Fifty-seven reports describing 130 cases of HZO or HZO-related complications were reviewed. Major risk factors for pediatric HZO included intrauterine exposure to varicella or primary varicella infection at a young age; HZO also occurred in patients who had received varicella vaccination. Both healthy and immunocompromised children were affected, with the majority of affected children being immunocompetent. The diagnosis of HZO is primarily clinical. Children appear to have good vision recovery and resolution of symptoms if they are treated promptly and if they adhere to treatment regimens, except for irreversible vision loss related to uncommon complications such as optic neuritis. CONCLUSION: HZO occurs in both healthy and immunocompromised children. Recognizing this treatable condition is essential for reducing ocular and systemic morbidity. Long-term follow-up and assessments of the impact on health in adulthood are lacking. More systematic study is needed to determine the incidence of HZO in children and appropriate diagnostic and treatment protocols for the care of pediatric patients with HZO.

Aseptic meningitis after amenamevir treatment for herpes zoster ophthalmicus with oculomotor nerve palsy in a patient taking immunosuppressant.

A 79-year-old woman presented with vomiting after being prescribed amenamevir by her primary care physician. She had a medical history of rheumatoid arthritis and was administered prednisolone and methotrexate. She was finally diagnosed with herpes zoster ophthalmicus and aseptic meningitis, and intravenous antiviral therapy was initiated. However, the patient developed oculomotor nerve palsy on the 11th day of hospitalization. In this case, there was a time lag between the administration of antiviral drugs and clinical improvement. Our case suggests the necessity of selecting antivirals, especially in high-risk cases of CNS complications, to avoid the low intracerebral transferability of antiviral drugs, including amenamevir.

Herpes Zoster Ophthalmicus With Dacryoadenitis Complicated by Recurrent Orbital Inflammation.

Herpes zoster ophthalmicus represents a zoster infection in the first division of the trigeminal nerve and has potentially serious complications involving the ocular and orbital structures. Herpes zoster ophthalmicus occurs in approximately 10% to 20% of individuals with herpes zoster and can lead to significant morbidity, particularly in patients with multiple comorbidities. The authors present a case of herpes zoster ophthalmicus along with dacryoadenitis in a patient with uncontrolled diabetes and rheumatoid arthritis who was misdiagnosed, had delayed treatment, and experienced recurrence with orbital symptoms during follow up. Prompt recognition, initiation of therapy and careful monitoring and follow up are important for treating herpes zoster ophthalmicus and preventing recurrence and long-term sequelae.

Dermatomal Granulomatous Dermatitis and Vasculitis Following Herpes Zoster Ophthalmicus.

Cutaneous granulomatous dermatoses are uncommon sequelae of herpes zoster (HZ) infection that have been documented in the literature, with granulomatous vasculitis described in rare cases. Here, we report a patient with HZ ophthalmicus who developed edematous plaques with central scarring in a V1 dermatomal distribution with histopathological changes of a granulomatous dermatitis including features of granulomatous vasculitis.

Herpes Zoster Opthalmicus-Related Ophthalmoplegia: Anatomical, Pathogenetic, and Therapeutic Perspectives.

OBJECTIVE: To investigate the anatomical, pathogenetic, and pharmacological characteristics of herpes zoster ophthalmicus (HZO)- related ophthalmoplegia. METHODS: Case report-based systematic review was performed. RESULTS: This study included 96 patients (54 [56.25%] women and 42 [43.75%] men [P = 0.221]). The mean age at presentation was 64.32 ± 17.48 years. All the patients included in the study had HZO- related ophthalmoplegia, with rash presenting as initial symptom in 87 (90.62%) cases, and diplopia in 9 (9.38%) cases. Thirty-seven (38.54%) patients achieved complete recovery, whereas 59 (61.46%) patients had permanent ophthalmoplegia. Females recovered in 26/54 cases and males in 11/42 cases (P = 0.028). Recovery rates after peroral versus intravenous antivirals (15/38 versus 19/46) and > 10 days versus ≤10 days antiviral treatment (22/54 versus 12/30) did not significantly differ ( P = 0.865 and P = 0.947, respectively). immunocompetent patients treated with corticosteroids had significantly better recovery rates compared to immunodeficient counterparts (17/34 [50.00%] and 5/22 [22.73%], respectively [ P = 0.041]). CONCLUSIONS: The outcome of HZO-related ophthalmoplegia is associated with gender, immune status, corticosteroid use, and time of antiviral treatment initiation.

Short-Term Peripheral Nerve Stimulation Relieve Pain for Elder Herpes Zoster Ophthalmicus Patients: A Retrospective Study.

OBJECTIVE: Ophthalmic postherpetic neuralgia (PHN) is the final stage of herpes zoster (HZ) ophthalmicus and a severe refractory neuropathic pain, thus there is no curative treatment that could alleviate pain and reduce the incidence of ophthalmic PHN now. The purpose of this study is to evaluate therapeutic efficacy of short-term peripheral nerve stimulation (PNS) for elder patients with HZ ophthalmicus. MATERIALS AND METHODS: We performed a retrospective study from March 2015 to August 2019 in our pain department. All the HZ ophthalmicus patients underwent supraorbital nerve short-term PNS were included. The patients' data, including numeric rating scale (NRS), 36-Item short form health survey (SF-36), and analgesic consumptions, were retrospectively analyzed. Severe side effects also were recorded. RESULTS: A total of 68 patients were enrolled in this study. The NRS scores were significantly decreased at different time points after short-term PNS compared to baseline (p < 0.001). The SF-36 scores, including general health, social function, emotional role, mental health, bodily pain, physical functioning, physical role, and vitality, were significantly improved at different time points after treatment (p < 0.001). The average dosages of tramadol and pregabalin administered (mg/d) were both significantly reduced compared to baseline (p < 0.001). There was no bleeding, infection, pain increase, and other side effects after treatment. CONCLUSIONS: Short-term PNS is an effective and safe therapeutic alternative for elder patients with HZ ophthalmicus and could reduce the incidence of ophthalmic PHN.

Comparison of visual field defect progression in secondary Glaucoma due to anterior uveitis caused by three types of herpes viruses.

PURPOSE: To clarify the prevalence of secondary glaucoma (SG) and its speed of progression in patients with herpes simplex virus (HSV)-anterior uveitis (AU), varicella zoster virus (VZV)-AU, and cytomegalovirus (CMV)-AU. METHODS: In total, 170 patients with herpetic AU were enrolled in this retrospective observational case series. Patients with visual field (VF) defects and glaucomatous disc abnormalities were diagnosed with SG. Moreover, the speed of SG progression was defined as decreasing mean deviation (MD) values per year. SG prevalence and annual MD-value decrease were compared among the three types of herpetic AU. RESULTS: SG prevalence was 16%, 9%, and 72% in patients with HSV-AU, VZV-AU, and CMV-AU, respectively. Patients with CMV-AU had the highest SG prevalence (odds ratio = 3.15; 95% confidence interval = 1.15-8.65; P < 0.05). Furthermore, the annual MD-value change was significantly higher in SG caused by CMV-AU than in that caused by HSV/VZV-AU (-2.6 ± 2.4 dB/year and -0.45 ± 0.54 dB/year, respectively; P < 0.05). CONCLUSIONS: Our results demonstrated that patients with CMV-AU may have a higher risk and faster speed of progression of SG than patients with HSV/VZV-AU. Therefore, clinicians should monitor glaucoma onset and VF-defect progression in patients with CMV-AU.

Local Administration of Methylcobalamin for Subacute Ophthalmic Herpetic Neuralgia: A Randomized, Phase III Clinical Trial.

OBJECTIVES: The ophthalmic branch of the trigeminal nerve is one of the most frequently involved sites of postherpetic neuralgia. A single-center randomized controlled study was conducted to evaluate the efficacy of local methylcobalamin injection for subacute ophthalmic herpetic neuralgia (SOHN). METHODS: One hundred and five patients with a pain score of 4 or greater were randomized to receive a combination of methylcobalamin and lidocaine via local injection (LM group, n = 35), intramuscular methylcobalamin and local lidocaine injection (IM group, n = 35), and oral methylcobalamin tablet and lidocaine local injection (OM group, n = 35) for 4 weeks. Multilevel mixed modeling was employed to examine treatment responses. RESULTS: Pain scores were reduced in all groups, but this reduction was significantly greater in the LM group (6.7 at baseline vs. 2.8 at endpoint) when compared with systemic administration (IM group 6.8 vs. 4.9, OM group 6.7 vs. 5.1). Clinically relevant reduction of pain (>30%) was seen in 91% of patients in the LM group, a significantly greater proportion than in the systemic groups (66% IM group, 57% OM group). Analgesic use reduced significantly in the LM group (94% at baseline vs. 6% at endpoint) but not in systemic groups (IM group 97% vs. 86%, OM group 94% vs. 80%). Health-related quality of life was higher in the LM group than in the systemic groups. In mixed modelling, increased age was associated with a lower response to methylcobalamin. CONCLUSIONS: This study indicates that local injection of methylcobalamin produces significant pain relief from SOHN and is superior to systemic administration.

[Acute retinal necrosis caused by varicella zoster virus]. / Ostryi nekroz setchatki, vyzvannyi virusom opoyasyvayushchego gerpesa.

Incidence of Herpes Zoster is relatively high. Herpes zoster ophthalmicus is one of the most common forms of the disease. Necrotising herpetic retinopathies (including acute retinal necrosis) are rare and usually these complications are presented in literature as individual cases. However, necrotising herpetic retinopathy can lead to complete loss of visual. The article reviews modern data on causation, diagnosis and treatment of acute retinal necrosis analyzing 40 open access articles from EBSCO published in 2011-2019, and describes the modern views on the prevalence and most important clinical features of herpetic acute retinal necrosis. Some contradictory opinions have been revealed concerning the diagnostic criteria and surgical treatment of acute retinal necrosis.

Clinical features of anterior uveitis caused by three different herpes viruses.

PURPOSE: To compare the clinical findings in patients with anterior uveitis (AU) caused by herpes simplex virus (HSV), varicella zoster virus (VZV), and cytomegalovirus (CMV). METHODS: We retrospectively analyzed the clinical profiles of HSV-AU (14 patients), VZV sine herpete (ZSH-AU: 21 patients), and CMV-AU (17 patients) diagnosed by the detection of corresponding viral DNA in aqueous humor samples by polymerase chain reaction. Further, five patients with Posner-Schlossman (P-S) syndrome were selected as controls for CMV-AU. RESULTS: Patients with CMV-AU were predominately male or older in age, and all cases were unilateral except for three patients with CMV-AU. Mutton-fat keratic precipitates (KPs) were found mostly in patients with HSV-AU and ZSH-AU. Severities of AU and viral load were the highest in ZSH-AU, followed by HSV-AU and CMV-AU. Iris atrophy was observed in HSV-AU (50%) and ZSH-AU (76%), with typical morphology of round type and sector type, respectively. In patients with CMV-AU, a ring-shaped KP was found in 53% patients, 76% of whom showed a decreased number of corneal endothelial cells. CMV was not detected in the aqueous humor of patients with typical P-S syndrome. CONCLUSION: Clinical findings of HSV-AU and VZV-AU were similar; however, more inflammatory findings were observed in VZV-AU. Iris atrophy morphologically differed in HSV-AU and VZV-AU. Inflammatory findings in CMV-AU were mild, and clinical features of iritis differed from those of the two former groups. A difference in the etiology between CMV-AU and P-S syndrome was observed.

Herpes Zoster: Epidemiological Links With Stroke and Myocardial Infarction.

Routine data from electronic health records (EHRs) provide insights into links between herpes zoster (HZ) and cardiovascular complications such as stroke or myocardial infarction (MI) in different populations worldwide. Evidence from large EHR studies using both self-controlled case series and traditional cohort designs suggests that there is a transient increase in the risk of stroke after HZ, which gradually resolves over 6-12 months. In these studies, herpes zoster ophthalmicus was associated with a higher risk of stroke than HZ at other sites. A larger effect size was seen in people aged under 40 years. Existing studies also suggest that HZ may have a triggering effect on MI, although fewer studies examined this outcome. Further evidence is needed on the effectiveness and cost-effectiveness of vaccine and antiviral drugs to reduce cardiovascular complications after HZ from studies that are designed to minimize selection biases and confounding by indication.

Isolated optic neuritis with a concurrent abnormal trigeminal nucleus on imaging: case report of a rare complication of herpes zoster ophthalmicus.

BACKGROUND: Herpes zoster ophthalmicus (HZO) is an inflammation related to reactivation of the latent varicella zoster virus (VZV), involving the ophthalmic branch of the trigeminal nerve. Optic neuritis (ON), a rare ocular complication following HZO, has been reported in 1.9% of HZO-affected eyes. Most previous cases occurred simultaneously with other ocular complications, especially orbital apex syndrome. Moreover, detailed magnetic resonance imaging (MRI) with diffusion weighted imaging of the optic nerve and trigeminal nucleus in HZO-related ON has been rarely reported. We report a case of postherpetic isolated ON with a concurrent abnormal trigeminal nucleus on imaging. CASE PRESENTATION: A healthy 58-year-old female presented with sudden painful visual loss in her right eye for 2 days. Four weeks before the presentation, her right eye was diagnosed with HZO, and she received intravenous acyclovir for 10 days. Ophthalmic examination revealed a visual acuity of light perception and 20/20 in the right and left eyes, respectively. A relative afferent pupillary defect was present in the right eye. Neurological examination was significant for hypoesthesia in the area of the HZO. A clinical diagnosis of HZO-related right retrobulbar ON was made, and other causes of atypical ON were excluded. MRI showed enhancement and restricted diffusion of the right-sided optic nerve with linear hyperintense T2 of the right-sided spinal trigeminal nucleus and tract (STNT) along the brainstem. She received 14 days of intravenous acyclovir and 5 days of methylprednisolone. Both were switched to an oral route for 2 months. After the completion of treatment, the visual acuity was counting fingers and 20/20 in the right eye and left eye, respectively. Stable brainstem STNT abnormalities and resolution of ON were found radiologically. CONCLUSIONS: Isolated ON is a rare ocular complication following HZO. An abnormal high signal of STNT on a T2 weighted image may be present, which may be a clue for VZV-associated complications, such as HZO-related ON, especially in cases lacking an obvious history of HZO or other concomitant ocular complications. Prompt treatment with both acyclovir and corticosteroids should be started. Restricted diffusion of the optic nerve may be a predictor for poor visual recovery.

Management of chronic complications associated with herpes zoster ophthalmicus.

PURPOSE OF REVIEW: Herpes zoster ophthalmicus (HZO) has the potential to cause significant visual morbidity and functional disability in patients with recalcitrant disease, keratitis, and postherpetic neuralgia. This article will review the current methods of prevention and treatment of anterior segment-related chronic complications of HZO. RECENT FINDINGS: HZO-related anterior segment ocular complications can range to include conjunctivitis, keratitis, and uveitis that can all be difficult to manage. Furthermore, many clinicians differ in their approach to disease management given the relative lack of large randomized controlled trials to guide therapy. The goal in managing complications of HZO is to reduce visual morbidity and to improve analgesia, and here, we present current recommendations for the management of anterior segment complications of HZO. SUMMARY: Recent advances in vaccine technology and the initiation of the Zoster Eye Disease Study improve the possibility of reducing the burden of disease while also further standardizing management of HZO.

Herpes Zoster Ophthalmicus With Orbital Findings Preceding Skin Rash.

The authors describe 2 patients who presented with orbital findings and later developed vesicular lesions that were positive for varicella zoster virus and consistent with Herpes Zoster ophthalmicus. One case is the first to involve dacryoadenitis and orbital myositis preceding disseminated Herpes Zoster. In the other case, a patient developed zoster orbital syndrome leading to elevated intraocular pressure, loss of vision, and afferent pupillary defect. Canthotomy and cantholysis were required to restore vision. In both cases, the orbital syndrome developed prior to the vesicular rash. These cases highlight the need to consider Herpes Zoster ophthalmicus in patients with orbital syndrome not responding to conventional treatment.

Varicella zoster virus reactivation antedating ipsilateral brainstem stroke.

itor Title: Varicella zoster virus reactivation antedating ipsilateral brainstem stroke Authors: Giuliana Galassi1, Maurilio Genovese2, Marisa Meacci3, Marcella Malagoli2 Affiliations: 1Department of Biomedical, Metabolic, Neural Sciences, University Hospital of Modena, Italy, 2Neuroradiology Service, University Hospital of Modena, Italy, 3Department of Laboratory Medicine and Patholgy, Microbiology and Virology Unit, University Hospital of Modena, Italy Corresponding Author: Giuliana Galassi, MD, Department of Biomedical, Metabolic, Neural Sciences, University Hospital of Modena, Via P. Giardini 1455, Modena, Italy, Tel: 39-3497325802, Email: giulianagalassi46@gmail.com Abstract: Varicella zoster virus (VZV) infection and reactivation are associated with a number of neurologic conditions. Unifocal large vessel infarcts may follow zoster in the trigeminal or cervical distribution as a result of transaxonal transport of virus from trigeminal or cervical afferent fibers that innervate vessels. Ophthalmic zoster (HZO) might cause ophthalmoplegic syndromes, with secondary optic neuritis. Mechanisms include local orbital muscle inflammation and, viral spread from the ophthalmic branch of the fifth nerve with associated vasculopathy. A 72-year-old man developed a vesicular rash in the territory of C5-T5-6. Within four weeks, the patient developed headache, dysphagia, left facial and extremity ataxic weakness. Magnetic resonance imaging (MRI) revealed a right pontine infarction. A 66-year-old woman presented with right-sided painfull HZO. One week later she developed complete external ophthalmoplegia and blurred vision. MRI showed ill-defined signal alteration in the retrobulbar tissue. Three weeks later, the patient was admitted because of dysarthria, deviated tongue, left-sided limb weakness, and tactile hypoesthesia. Spinal fluid contained 23 lymphocytes/mm3 and increased protein. The serum contained antibodies to VZV IgG and IgM in both cases. The patients received intravenously acyclovir with improvement. This report confirms unusual occurrence of ipsilateral brainstem stroke after VZV reactivation in immunocompetent subjects.

Herpes zoster keratitis development after acute retinal necrosis.

PURPOSE: To report a case of herpes zoster keratitis in a patient undergoing treatment for herpetic acute retinal necrosis. METHODS: Case report. RESULTS: A 71 year old male presented with acute retinal necrosis of the left eye due to herpes zoster and was treated with intravitreal foscarnet and oral valcyclovir. He developed a retinal detachment and underwent surgical repair. After four weeks, he developed an ipsilateral herpetic zoster keratitis demonstrated by Rose-Bengal staining that was responsive to topical ganciclovir gel. CONCLUSIONS: This case report describes the unusual development of herpes zoster keratitis after the development of unilateral acute retinal necrosis (ARN) in a patient on antiviral treatment.

Genetic analysis of varicella-zoster virus in the aqueous humor in uveitis with severe hyphema.

BACKGROUND: Genetic variations have been identified in the genome of varicella-zoster virus (VZV) strains using vesicle fluid, varicella scabs and throat swab samples. We report a rare case of VZV-associated uveitis with severe hyphema, which was immediately diagnosed by polymerase chain reaction (PCR) using the aqueous humor, in which we were able to analyze the VZV genotype for the first time. CASE PRESENTATION: A 16-year-old Japanese boy was referred to our hospital with a 20-day history of unilateral anterior uveitis and 11-day history of hyphema. At presentation, details of the iris, the iridocorneal angle, and the fundus were not visible due to the severe hyphema. Serum anti-VZV IgG and anti-VZV IgM were elevated, and 1.61 × 109 copies/mL of VZV-DNA were detected by real-time PCR using the aqueous humor. As there were no eruptions on his face or body, we diagnosed zoster sine herpete and started intravenous administration of prednisolone and acyclovir. The hyphema completely disappeared 2 weeks after presentation, while sectorial iris atrophy and mild periphlebitis of the fundus became gradually apparent. Anterior inflammation and periphlebitis gradually improved and VZV-DNA in the aqueous humor was reduced to 1.02 × 106 copies/mL at 4 weeks after presentation. Examination by slit lamp microscope revealed no inflammation after 5 months, and VZV-DNA could no longer be detected in the aqueous humor. Serum anti-VZV IgG and anti-VZV IgM also showed a gradual decrease along with improvement in ocular inflammation. The genetic analysis of multiple open reading frames and the R5 variable repeat region in the VZV genes, using DNA extracted from the aqueous humor at presentation, showed that the isolate was a wild-type clade 2 VZV strain (prevalent in Japan and surrounding countries) with R5A allele and one SNP unique to clade 1 (both are major types in Europe and North America). CONCLUSIONS: VZV-associated uveitis may develop hyphema that obscures ocular inflammation, thus PCR analysis using the aqueous humor is the key investigation necessary for the diagnosis. The measurement of VZV-DNA copies by real-time PCR would be useful for evaluation of therapeutic effects. We could amplify and analyze VZV genotype using the aqueous humor including a very large number of VZV-DNA copies (1.61 × 109 copies/mL).
