Short-Term Supraorbital Nerve Stimulation and Pain Relief for Acute and Subacute Ophthalmic Herpetic Neuralgia: A Randomized Controlled Crossover Trial.

BACKGROUND: Herpes zoster ophthalmicus (HZO) is a kind of refractory disease, and treating it is important for preventing postherpetic neuralgia (PHN). But the evidence surrounding the current treatment options for these conditions is controversial, so exploring reasonable clinical treatment strategies for HZO is necessary. Neuromodulation is an excellent modality for the treatment of various neuropathic pain conditions. This trial was designed to evaluate the effectiveness of short-term supraorbital nerve stimulation (SNS) and the supraorbital nerve block (SNB) for HZO. OBJECTIVES: To determine whether short-term SNS relieves acute and subacute ophthalmic herpetic neuralgia. STUDY DESIGN: This prospective randomized controlled crossover trial compared short-term SNS to SNB. SETTING: The operating room of a pain clinic. METHODS: Patients with acute or subacute ophthalmic herpetic neuralgia were recruited. The patients were randomly assigned to receive either SNS or SNB. The primary outcome being measured was each patient's Visual Analog Scale (VAS) score at 4 weeks. The secondary outcomes under measurement were the proportion of patients who achieved ≥ 50% pain relief, sleep quality, medicine consumption, and adverse events. Crossover after 4 weeks was permitted, and patients were followed up to 12 weeks. RESULTS: Overall, 50 patients were included (n = 25/group). At 4 weeks, the patients who received SNS achieved greater pain relief, as indicated by their significantly different VAS scores from those of the SNB group (mean difference: -1.4 [95% CI, -2.29 to -0.51], P < 0.05). Both groups showed a significant decrease in pain level from the baseline (all P < 0.05). Overall, 72% and 44% of the SNS and SNB patients experienced ≥ 50% pain relief, respectively (OR: 0.31 [95% CI, 0.09 to 0.99], P < 0.05), and 68% and 32% of SNS and SNB patients, respectively, had VAS scores < 3 (OR: 0.22 [95% CI, 0.07 to 0.73], P < 0.05). Compared to the SNB group, the SNS group had better sleep quality, lower ophthalmic neuralgia, a lower proportion of further treatment, and lower analgesic intake. Overall, 18 patients received SNS alone, and 16 patients crossed over from SNB to SNS. The VAS scores, sleep quality, ophthalmic neuralgia, and trend of medicine intake were not significantly different between the groups (all P > 0.05). No serious complications occurred. LIMITATIONS: This study was nonblind. CONCLUSIONS: Short-term SNS is effective for controlling acute or subacute ophthalmic herpetic neuralgia. Combining SNS with SNB yields no additional benefits.

Radiofrequency regulation of the sphenopalatine ganglion in managing herpes zoster ophthalmicus neuralgia: A case series.

INTRODUCTION: Trigeminal herpes zoster, which comprises 10% to 20% of cases of herpes zoster, often leads to severe pain in the ophthalmic branches. Current treatments, including drug therapy and minimally invasive interventions, have limitations; accordingly, there is a need to explore alternative approaches. This study aimed to evaluate the efficacy and safety of computerized tomography (CT)-guided pulsed radiofrequency of the sphenopalatine ganglion in patients with intractable trigeminal herpetic pain. PATIENT CONCERNS: Three patients with intractable trigeminal ophthalmic zoster neuralgia were studied. All patients complained of bursts of headache, which occurred at least 10 times a day, usually in the periorbital and frontal regions. Conventional treatments, including oral medications and radiofrequency therapy targeting the trigeminal-semilunar ganglion and supraorbital nerve, could not sufficiently provide relief. DIAGNOSIS: Two patients were diagnosed with herpes zoster in the ocular branch of the trigeminal nerve with conjunctivitis, while one patient was diagnosed with postherpetic neuralgia in the ocular branch of the trigeminal nerve. INTERVENTIONS: This study employed a novel approach that involved CT-guided radiofrequency regulation of the pterygopalatine fossa sphenopalatine ganglion. OUTCOMES: In all three patients, pain relief was achieved within 1 to 3 days after treatment. During the follow-up, one patient had pain recurrence; however, its severity was ≈ 40% lower than the pretreatment pain severity. The second patient had sustained and effective pain relief. However, the pain of the third patient worsened again after 2 months. The average follow-up duration was 3 months. None of the enrolled patients showed treatment-related adverse reactions or complications. CONCLUSION: Our findings indicated that CT-guided radiofrequency regulation of the pterygopalatine fossa sphenopalatine ganglion was a safe and effective intervention for pain in patients with trigeminal ophthalmic zoster neuralgia, suggesting that it may be a therapeutic option if other treatments fail.

Dual-neuromodulation strategy in pain management of herpes zoster ophthalmicus: retrospective cohort study and literature review.

BACKGROUND: Effective pain control of herpes zoster ophthalmicus (HZO) is not only essential to attenuate the clinical symptoms but to reduce the risk of postherpetic neuralgia development. Recently, neuromodulation therapy has been one promising option for neuropathic pain and increasingly applied in management of zoster-related pain. One key factor of neuromodulation treatment is the therapeutic site for the impaired nerves. In this study we aim to investigate one novel dual-neuromodulation strategy, targeting the level of the peripheral branch and trigeminal ganglion, in the pain management of HZO. METHODS: Dual neuromodulation strategy combining short-term peripheral nerve stimulation (PNS) with pulsed radiofrequency (PRF) of trigeminal ganglion was compared with single PNS treatment for HZO-related pain. Clinical recordings of patients were retrospectively reviewed. The primary outcome was the pain severity, assessed by the visual analogue scale (VAS) before and after neuromodulation therapy. RESULTS: PNS achieved significant relief of pain with or without PRF treatment before discharge, which provided enduring therapeutic effect up to 12-month follow-up. The mean reduction of VAS was 6.7 ± 1.4 in dual modulation therapy (n = 13) at last follow-up and 5.4 ± 1.5 in PNS subgroup (n = 20), respectively. Moreover, dual modulation strategy provided better control of pain compared with PNS therapy alone at each time point. CONCLUSION: It is feasible and effective to combine the PNS and PRF in pain management of HZO. This novel dual modulation strategy of trigeminal pathway may provide additional therapeutic effects of pain symptoms in HZO population.

Dual neuromodulation strategy for pain management of herpes zoster ophthalmicus is proposed, with regard to stimulation site (peripheral and trigeminal ganglion) and apparatus (electrical nerve stimulation and pulsed radiofrequency).Superior clinical outcome was associated with novel neuromodulation therapy with dual therapeutic targets, when compared with peripheral nerve stimulation in treatment of herpes zoster ophthalmicus.We conducted literature review to compare distinct pattern of neuromodulation (peripheral nerve stimulation and radiofrequency) in treatment of trigeminal neuropathic pain caused by herpes zoster.

Comparison of the Efficacy of Short-term Peripheral Nerve Stimulation and Pulsed Radiofrequency for Treating Herpes Zoster Ophthalmicus Neuralgia.

OBJECTIVE: This study aimed to investigate the effect of therapy with peripheral nerve stimulation (PNS) and pulsed radiofrequency (PRF) combined or PNS and PRF separately in patients with herpes zoster ophthalmicus (HZO). MATERIALS AND METHODS: This cohort study included 106 cases of HZO. Three groups were identified according to the type of treatment received: combination therapy (PNS+PRF) (n=38), PRF (n=37), and PNS (n=31). The observations at 0, 1, 2, and 4 weeks; 3 and 6 months; and 1 and 2 years after the operation were analyzed. Observations at each follow-up included baseline characteristics, Numerical Rating Scale (NRS) and the Pittsburgh Sleep Quality Index (PSQI), concomitant pain medication usage, relapse rate, and adverse events. RESULTS: The postoperative NRS of all 3 groups were significantly lower than preoperative scores. The PSQI of the 3 groups was significantly improved postoperatively, and the concomitant pain medication gradually decreased. Regarding long-term efficacy, the pain NRS and PSQI scores of the PNS+PRF and PNS groups were significantly lower than those of the PRF group ( P <0.05), and the relapse rate of the PRF group was higher than that of the PNS+PRF and PNS groups ( P <0.05). No significant difference was observed between the PNS+PRF and the PNS groups. CONCLUSION: Both PNS and PRF treatment of HZO can decrease the pain score, yielding no serious complications. The combination of PNS and PRF or PNS alone resulted in more significant pain relief than treatment with PRF alone. Thus, PNS therapy may be a better treatment option for HZO.

Herpes Zoster: A Brief Definitive Review.

ABSTRACT: This brief definitive review of herpes zoster (HZ) will cover the current state of knowledge and questions that remain to be answered regarding HZ in general and HZ ophthalmicus in particular. A question-and-answer format will be used to address various important topics related to this common and serious disease. Questions to be addressed relate to common misconceptions, contagiousness of infection, unknowns regarding pathogenesis, rising incidence, risk factors and complications, relationship with temporal arteritis, vaccination, and current and future antiviral treatment. In addition, the importance of the Zoster Eye Disease Study to determine the efficacy of suppressive valacyclovir treatment in preventing complications of HZ ophthalmicus and the need to support enrollment will be discussed.

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.

Supraorbital Nerve Radiofrequency for Severe Neuralgia Caused by Herpes Zoster Ophthalmicus.

Background: Radiofrequency of the Gasserian ganglion can be used for ophthalmic herpetic neuralgia (OHN), but it is associated with complications. This study aimed to use the supraorbital nerve for computed tomography- (CT-) guided radiofrequency thermocoagulation to treat refractory OHN. Methods: This was a retrospective case series study of patients with simple or combined OHN treated at our hospital between 06/2012 and 06/2018. The numerical rating score (NRS), spontaneous pain, allodynia, gabapentin dosage, paracetamol/oxycodone dosage, patient global impression of change (PGIC) score, Barrow numbness score, postoperative 360-day recurrence rate, and complications were recorded before the operation and at 1, 30, 90, 180, and 360 days after the operation. Results: Compared with baseline, the NRS was decreased, and PGIC was increased at postoperative 1, 30, 90, 180, and 360 days, and the gabapentin and paracetamol oxycodone doses at postoperative 30, 90, 180, and 360 days were decreased (all P < 0.001). Compared with 1 day after the operation, numbness was decreased at 30, 90, 180, and 360 days after the operation (P < 0.001). Compared with baseline, the number of patients with allodynia at each time point after the operation was decreased (P < 0.001), but without a difference for spontaneous pain (P=0.407). No subjects showed drooping eyelid, corneal ulcers, eyeball damage, decreased vision, and other severe complications. Conclusion: CT-guided supraorbital nerve radiofrequency thermocoagulation for the treatment of OHN can effectively relieve pain and reduce the dose of analgesics, without any serious complication. This study suggests that this technique is feasible and applicable to clinical practice.

Queratopatía neurotrófica postherpética: etiopatogenia, clínica y terapias actuales / Post-herpes neurotrophic keratopathy: Aetiopathogenesis, clinical signs and current therapies

La queratopatía neurotrófica (QN) es una enfermedad corneal degenerativa causada por un daño en la inervación del nervio trigémino. Esta situación produce defectos epiteliales, ulceración y, eventualmente, perforación. Tanto la queratitis por herpes simple como por varicela zoster constituyen la principal causa de QN. Además, el pronóstico en este tipo de QN es pobre. Los hallazgos clínicos clásicos en la QN postherpética incluyen la rotura epitelial espontánea, defectos epiteliales ovalados y centrales de bordes suaves, queratolisis con adelgazamiento del estroma, cicatrización y neovascularización. Aunque se han descrito tratamientos médicos y quirúrgicos prometedores, actualmente no hay un tratamiento definitivo para restaurar la sensibilidad de la córnea. Por tanto, la QN sigue siendo un reto terapéutico. En esta revisión resumimos la patogenia, la clínica y el tratamiento actual de la QN postherpética. Se discute el papel del tratamiento antiviral y de las vacunas contra el virus de la varicela-zoster. Se describen nuevas terapias médicas y quirúrgicas, como los agentes regenerativos y la neurotización corneal

Neurotrophic keratopathy (NK) is a degenerative corneal disease caused by damage of trigeminal innervation. This leads to epithelial defects, ulceration and, eventually, perforation. Both herpes simplex and varicella zoster keratitis are reported to be the main causes of NK. Furthermore, prognosis in this type of NK is poor. Classic clinical findings in post-herpes NK are spontaneous epithelial breakdown, round and central epithelial defects with smooth edges, stromal melting and thinning, scarring, and neovascularisation. Although several medical and surgical treatments have been reported, no therapies are currently available to definitely restore corneal sensitivity. Therefore, NK remains a challenging disease to treat. In this review a summary is presented of the pathogenesis, manifestations, and current management of post-herpes NK. The role of antiviral treatment and varicella-zoster vaccination is also discussed. A description is also presented on both medical and surgical novel therapies, such as regenerative drugs and corneal neurotization

Diagnosis and Treatment of Acute Retinal Necrosis: A Report by the American Academy of Ophthalmology.

PURPOSE: To evaluate the available evidence in peer-reviewed publications about the diagnosis and treatment of acute retinal necrosis (ARN). METHODS: Literature searches of the PubMed and Cochrane Library databases were last conducted on July 27, 2016. The searches identified 216 unique citations, and 49 articles of possible clinical relevance were reviewed in full text. Of these 49 articles, 27 were deemed sufficiently relevant or of interest, and they were rated according to strength of evidence. An additional 6 articles were identified from the reference lists of these articles and included. All 33 studies were retrospective. RESULTS: Polymerase chain reaction (PCR) testing of aqueous or vitreous humor was positive for herpes simplex virus (HSV) or varicella zoster virus (VZV) in 79% to 100% of cases of suspected ARN. Aqueous and vitreous specimens are both sensitive and specific. There is level II and III evidence supporting the use of intravenous and oral antiviral therapy for the treatment of ARN. Data suggest that equivalent plasma drug levels of acyclovir can be achieved after administration of oral valacyclovir or intravenous acyclovir. There is level II and III evidence suggesting that the combination of intravitreal foscarnet and systemic antiviral therapy may have greater therapeutic efficacy than systemic therapy alone. The effectiveness of prophylactic laser or early pars plana vitrectomy (PPV) in preventing retinal detachment (RD) remains unclear. CONCLUSIONS: Polymerase chain reaction testing of ocular fluid is useful in supporting a clinical diagnosis of ARN, but treatment should not be delayed while awaiting PCR results. Initial oral or intravenous antiviral therapy is effective in treating ARN. The adjunctive use of intravitreal foscarnet may be more effective than systemic therapy alone. The role of prophylactic laser retinopexy or early PPV is unknown at this time.

[Clinical presentations of Herpes Zoster Ophthalmicus (diagnosis and therapy)]. / Klinicheskie proyavleniya Herpes Zoster Ophthalmicus (diagnostika i terapiya).

Approximately a quarter of the world's population at some point in life is at risk of developing shingles (Herpes Zoster). In 10-20% of cases the first branch of the trigeminal nerve gets involved (Herpes Zoster Ophthalmicus, HZO). Ophthalmic complications of HZO are able to cause a significant reduction in visual function. AIM: To study and summarize clinical features of HZO (including the rate of complications and their nature) and to determine the relationship between clinical and laboratory data from these patients. MATERIAL AND METHODS: The study included 133 patients with ophthalmic and neurological complications of HZO (group 1 (n=28) - retrospective analysis of outpatient records for the period 1995-2005; group 2 (n=95) - a prospective study for the period 2005-2015), who received a course of conservative treatment in either the Botkin City Hospital, branch № 1, or in the ophthalmic department of the Moscow herpes centre (Gerpeticheskiy Tsentr Ltd.). Laboratory tests were performed only in patients from group 2 and included: examination of biological fluids for six types of herpes viruses by polymerase chain reaction, examination of tears and urine for DNA of Chlamydia, Mycoplasma, and Ureaplasma, and serological blood testing for markers of herpes virus infection. Patients from group 1 were prescribed topical antiviral, antibacterial, and anti-inflammatory therapy, in rare cases - acyclovir per os. In group 2, the treatment included systemic antiviral medications and immune correction therapy. Anti-inflammatory therapy consisted of local and systemic non-steroidal agents (NSAIDs). RESULTS: The most common ophthalmic complications of HZO in both groups were stromal keratitis and keratoiridocyclitis, neurological - III and VI cranial nerves palsies. The duration of the disease in the first group ranged from 2 months to 3 years; in the second group, patients were divided into two subgroups: subgroup A with the disease duration of no more than one month (n=81) and subgroup B with the disease duration from 1.5 to 9 months (n=14). Varicella-zoster virus (VZV) DNA was present in tears and/or other biological fluids of patients from group 2 in more than 70% of cases (n=67). Particularly, in 27.4% of cases the virus was isolated in two fluids and in 7.4% of cases - in three fluids. The duration of virus production in tears and other biological fluids (saliva, blood, and urine) ranged from 10 days to 4 months. CONCLUSION: Topical non-steroidal anti-inflammatory drugs and systemic etiological treatment in case of intraocular inflammation in HZO patients may reduce the risk of severe consequences of VZV reactivation and help avoid recurrences later in life.

Herpes zoster ophthalmicus and varicella zoster virus vasculopathy.

Herpes zoster (HZ) corresponds to the reactivation of varicella zoster virus (VZV). Among adults, the ophthalmic division of the trigeminal nerve is one of the most common sites of involvement. Vasculopathy caused by HZ is associated with significant morbidity and mortality, affecting structures such as the brain, which can lead to stroke. In this review, we analyzed the epidemiological and clinical aspects of the vascular involvement of VZV, focusing on the peculiarities of its association with ocular HZ. A review of the available literature indicated that ocular involvement of HZ was a risk factor for vasculopathy after adjusting for age, sex, body mass index, smoking, indicators of metabolic syndrome, and vascular and heart diseases. Considering the severity of this complication, vascular disease mediated by VZV requires early diagnosis and aggressive treatment. Finally, the anti-HZ vaccine has been recommended as a prophylactic measure in the elderly, but it should be used with caution in immunocompromised individuals.

ABSTRACT Herpes zoster (HZ) corresponds to the reactivation of varicella zoster virus (VZV). Among adults, the ophthalmic division of the trigeminal nerve is one of the most common sites of involvement. Vasculopathy caused by HZ is associated with significant morbidity and mortality, affecting structures such as the brain, which can lead to stroke. In this review, we analyzed the epidemiological and clinical aspects of the vascular involvement of VZV, focusing on the peculiarities of its association with ocular HZ. A review of the available literature indicated that ocular involvement of HZ was a risk factor for vasculopathy after adjusting for age, sex, body mass index, smoking, indicators of metabolic syndrome, and vascular and heart diseases. Considering the severity of this complication, vascular disease mediated by VZV requires early diagnosis and aggressive treatment. Finally, the anti-HZ vaccine has been recommended as a prophylactic measure in the elderly, but it should be used with caution in immunocompromised individuals.

RESUMO Herpes zoster (HZ) corresponde à reativação do vírus varicela zoster (VVZ) e, entre os adultos, o envolvimento da divisão oftálmica do nervo trigêmeo é um dos locais mais comuns A vasculopatia associada ao HZ é uma complicação dotada de grande morbimortalidade e afeta diferentes estruturas, favorecendo, inclusive o acidente vascular cerebral. Nesta revisão analisamos aspectos epidemiológicos e clínicos da vasculopatia mediada pelo VZV, bem como as peculiaridades relacionadas com o HZ ocular. De acordo com dados disponíveis na literatura, o acometimento ocular pelo HZ mostrou ser um fator de risco para vasculopatia após se ajustar para idade, sexo, índice de massa corporal, tabagismo, indicadores da síndrome metabólica, doença vascular e cardiopatias. Em face da gravidade dessa complicação, a doença vascular mediada pelo VZV requer diagnóstico precoce e tratamento agressivo. A vacina anti-HZ tem sido recomendada profilaticamente em idosos, mas deve ser usada com cautela em indivíduos imunocomprometidos.

Corneal Reinnervation and Sensation Recovery in Patients With Herpes Zoster Ophthalmicus: An In Vivo and Ex Vivo Study of Corneal Nerves.

PURPOSE: To study corneal reinnervation and sensation recovery in Herpes zoster ophthalmicus (HZO). METHODS: Two patients with HZO were studied over time with serial corneal esthesiometry and laser in vivo confocal microscopy (IVCM). A Boston keratoprosthesis type 1 was implanted, and the explanted corneal tissues were examined by immunofluorescence histochemistry for ßIII-tubulin to stain for corneal nerves. RESULTS: The initial central corneal IVCM performed in each patient showed a complete lack of the subbasal nerve plexus, which was in accordance with severe loss of sensation (0 of 6 cm) measured by esthesiometry. When IVCM was repeated 2 years later before undergoing surgery, case 1 showed a persistent lack of central subbasal nerves and sensation (0 of 6). In contrast, case 2 showed regeneration of the central subbasal nerves (4786 µm/mm) with partial recovery of corneal sensation (2.5 of 6 cm). Immunostaining of the explanted corneal button in case 1 showed no corneal nerves, whereas case 2 showed central and peripheral corneal nerves. Eight months after surgery, IVCM was again repeated in the donor tissue around the Boston keratoprosthesis in both patients to study innervation of the corneal transplant. Case 1 showed no nerves, whereas case 2 showed new nerves growing from the periphery into the corneal graft. CONCLUSIONS: We demonstrate that regaining corneal innervation and corneal function are possible in patients with HZO as shown by corneal sensation, IVCM, and ex vivo immunostaining, indicating zoster neural damage is not always permanent and it may recover over an extended period of time.

Acute retinal necrosis--a case report.

Acute retinal necrosis (ARN) is a rare but very severe form of retinitis. In contrast to progressive outer retinal necrosis acute retinal necrosis typically affects immunocompetent individuals. Herpes Simplex and Varicella-zoster viruses play the main role in the development of the disease. We report a case study of a healthy, young male who presented to the ophthalmologist with unilateral visual acuity decrease and eye irritation. The acute retinal necrosis was diagnosed and a therapy was started including both systemic and local anti-viral agents, as well as an oral anticoagulant. Additional systemic steroid therapy was introduced a week later. The regression of retinal inflammatory changes and the improvement of visual acuity were observed. The polymerase chain reaction assay for the presence of viral DNA in serum was negative. The IgM antibody assay for potential causal pathogens was negative, but the level of Varicella-zoster virus IgG antibodies was markedly elevated. During the follow-up, the patient developed retinal detachment and pars plana vitrectomy with silicone oil endotamponade was performed. Although the surgery resulted in the successful retinal reattachment, the final visual acuity remained decreased. Six months after the surgery, the eye was free of the intraocular inflammation and the visual acuity slightly improved.

[Activity and cost related to hospital management of herpes zoster in France: focus on ophthalmic herpes zoster]. / Activité hospitalière et coûts liés à la prise en charge du zona en France : focus sur le zona ophtalmique.

OBJECTIVES: Herpes zoster secondary to reactivation and replication of the varicella zoster virus (VZV) caused a painful disease which impact the quality of life. Among the complications, herpes zoster ophtalmicus was responsible to post-herpetic neuralgia and lesions of the ocular globus. The aim of this study is to evaluated the burden and cost of herpes zoster in secondary care in France with focus on herpes zoster ophtalmicus (HZO). METHODS: This retrospective analysis was performed using data extracted from the French medical information system during the year 2012. The diagnosis are coded using the international classification of diseases as primary, related or significant associated diagnosis. RESULTS: During the year 2012, 2,509 patients 50 years old and more were admitted secondary to HZ. Among them, 495 were admitted with an HZO (19.7%). The mean age of patients hospitalized were 77 years. The average cost per stay varied between 3,370 euros and 9,191 euros respectively for zoster without complications and for encephalitis. The overall total hospitalization due to HZ and its complications was around 10.2 million euros in France in 2012, 18% of these costs were attributable to hospitalizations for HZO. CONCLUSION: This study evaluated the cost of hospitalization due to zoster for the French health insurance. This total costs were probably underestimate because the non-exhaustiveness of CIM coding. This study shows the burden of zoster and his cost particularly heavy when ophtalmicus or neurological complications were associated to HZ.

Late reactivation of herpes zoster keratitis results in band keratopathy.

PURPOSE: To report an unusual case of a late-stage reactivation of immune stromal keratitis associated with herpes zoster ophthalmicus (HZO), occurring without any apparent predisposing factors, more than 4 years after an acute zoster dermatomal rash. Significant corneal hypoesthesia and a central band keratopathy developed within 6 months of the late-stage reactivation. The clinical case management, issues associated with management, and management options are discussed, including the use of standardized, regulatory approved, antibacterial medical honey. CASE REPORT: An 83-year-old woman presented for routine review with a reactivation of right anterior stromal keratitis and mild anterior uveitis, occurring more than 4 years after an acute HZO dermatomal rash and an associated initial episode of anterior stromal keratitis. Corneal sensation became markedly impaired, and over the subsequent 6 months, a right central band keratopathy developed despite oral antiviral and topical steroid therapy. Visual acuity with pinhole was reduced to 20/100 in the affected eye and moderate irritation and epiphora were experienced. The patient declined the surgical intervention options of chelation, lamellar keratectomy, and phototherapeutic keratectomy to treat the band keratopathy. Longer-term management has involved preservative-free artificial tears, eyelid hygiene, standardized antibacterial medical honey, topical nonpreserved steroid, and UV-protective wraparound sunglasses. The clinical condition has improved over 14 months with this ocular surface management regimen, and visual acuity of 20/30 is currently achieved in a comfortable eye. CONCLUSIONS: The chronic and recurrent nature of HZO can be associated with significant corneal morbidity, even many years after the initial zoster episode. Long-term review and management of patients with a history of herpes zoster stromal keratitis are indicated following the initial corneal involvement. Standardized antibacterial medical honey can be considered in the management of the chronic ocular surface disease associated with HZO and warrants further evaluation in clinical trials.

Clinical features of ocular herpetic infection in an italian referral center.

PURPOSE: The aim of this study was to describe clinical manifestations of herpetic ocular infection caused by herpes simplex virus (HSV), varicella zoster virus (VZV), and cytomegalovirus (CMV) in a referral center in Northern Italy. METHODS: This retrospective study included 241 patients with herpetic ocular infection referred to the tertiary-care Ocular Immunology and Uveitis Service, at the San Raffaele Scientific Institute in Milan, from January 2006 to August 2013. The main clinical parameters evaluated were etiology, clinical features, ocular complications, and recurrences of the infection. RESULTS: Two hundred forty-one patients (144 female and 97 male) were followed for a mean time of 24.9 ± 18.2 months (range, 12-72). One hundred eighty-nine (78.4%) patients had HSV, 45 (18.7%) had VZV, and 7 (2.9%) had CMV infection. In the HSV and VZV groups, the most frequent manifestation was keratitis (41.3% and 31.1%, respectively), followed by anterior uveitis (33.3% and 28.9%, respectively). The most common CMV presentation was retinitis (71.4%). The main complications observed were glaucoma (38.1% in HSV group, 40% in the VZV group, and 28.6% in the CMV group) and cataract (27.5% in HSV group, 26.7% in VZV group, and 28.6% in CMV group), whereas retinal detachment frequently occurred in patients with retinitis (50%, 42.9%, and 40% among HSV, VZV, and CMV patients, respectively). Recurrences were observed in 65.1%, 51.1%, and 28.6% of patients with HSV, VZV, and CMV, respectively. CONCLUSIONS: Manifestations of herpetic ocular disease in our patients are comparable with other published series. However, the rate of ocular complications and recurrences during follow-up were higher compared with other series.

Assessment and management of patients with acute red eye.

This article provides an overview of the role of the nurse in the assessment and management of five ocular conditions that give rise to an acute red eye in older people. The conditions discussed are acute closed angle glaucoma, acute iritis, acute conjunctivitis, herpes zoster ophthalmicus and bacterial corneal ulcer.
