Background Herpes zoster ophthalmicus (HZO) accounts for 10–20% of all patients with herpes zoster.
Objectives This study aimed to evaluate demographic features, clinical presentations, and outcomes of HZO patients.
Patients and methods In a prospective cross-sectional clinical study, it included 64 patients with clinically evident HZO. All patients underwent a detailed medical history and complete dermatological and ophthalmological examinations.
Results This study included 64 patients with HZO; 41 (64.1%) were females and 23 (35.9%) were males. Of female patients with HZO, 30 (73.2%) were married, 20 (48.7%) were urban, 35 (85.4%) were housewives, 17 (41.4%) had medium socioeconomic levels, 41 (100%) were nonsmokers, 13 (31.70%) had diabetes mellitus, six (14.63%) had hypertension, 30 (73.2%) had eruption on the left side, 11 (26.8%) had conjunctivitis and lid edema, 13 (31.7%) had postherpetic neuralgia, 29 (70.7%) had posttreatment scars, and six (14.6%) had a reduced visual outcome. Of male patients with HZO, 20 (87%) were married, 12 (52.2%) were suburban, seven (30.4%) were worker, 14 (60.9%) had low socioeconomic levels, 15 (65.2%) were smokers, eight (34.8%) had diabetes mellitus, one (4.3%) had hypertension, 18 (78.3%) had eruption on the left side, nine (39.16%) had conjunctivitis and lid edema, seven (30.4%) had postherpetic neuralgia, 10 (43.5%) had post-HZO cutaneous scarring, and four (17.4%) had a reduced visual outcome.
Limitations The sample size of this study was small.
Conclusion This study concluded that HZO is a common and potentially ruinous disease that may show a significant ophthalmic morbidity if not adequately diagnosed and treated.

| Introduction|| |
Herpes zoster (HZ) is a reactivation of the varicella zoster virus (VZV), most commonly presented in the elderly and immunosuppressed patients, with incidence estimates ranging from 1.25 to 5.25 per 1000 person-years .
Herpes zoster ophthalmicus (HZO) was defined as VZV infection within the ophthalmic division of the fifth cranial nerve. HZO accounts for 10–20% of all patients with HZ .
HZO occurs when reactivation of the latent virus in the trigeminal ganglia involves the ophthalmic division of the nerve. The virus has gangrenous effects on the eye and surrounding structures by secondary perineural and intraneural inflammation of sensory nerves .
Age and race appear to be essential demographic features in determining the risk of HZO . The incidence and prevalence of HZO appeared to be increasing due to reasons cited include an older population with inherent immune senescence, immunosuppression by pharmacotherapy, immunocompromising diseases such as AIDS, and universal varicella vaccination in the young leading to fewer exposures within the community to maintain cell-mediated immunity .
The prodromal phase of HZO includes fatigue, malaise, and low-grade fever that lasts up to 1 week before the rash over the forehead appears . About 60% of patients have several degrees of dermatomal pain in the distribution of the ophthalmic nerve . Subsequently, erythematous macules appear along the involved dermatome then rapidly progressing over several days to papules and vesicles containing clear serous fluid and later pustules. These lesions rupture and typically crust over, requiring several weeks to heal .
Although no vesicular eruption was present at initial neuro-ophthalmic consultation many features suggested HZO: (a) dermatome of fifth cranial nerve distribution of pain; (b) partial pain relief with palpation; (c) lack of other symptoms to suggest giant cell arteritis; and (d) normal acute phase reactant levels .
HZO can be classified into HZO with or HZO without eye affection . In the era of preantiviral treatment, ∼50% of patients with HZO developed ocular involvement .
The most common ophthalmic manifestations in HZO patients are keratitis, uveitis, and conjunctivitis. Other manifestations include episcleritis and scleritis, acute retinal necrosis, cranial nerve involvement, and/or meningoencephalitis .
Long-term structural complications including glaucoma, cataract, corneal scarring, and postherpetic neuralgia (PHN) can have devastating outcomes on visual function and/or quality of life of the patients .
Antiviral drugs such as acyclovir, valacyclovir, and famciclovir remain the mainstay of therapy and are the most effective lines of treatment in preventing ocular affections when start within 72 h after the onset of the skin rash .
This study aimed to evaluate demographic features, clinical presentations, and outcomes of HZO patients.
| Patients and methods|| |
This study was a prospective cross-sectional clinical design. It included 64 patients with clinically evident HZO who attended to Clinics of Dermatology, Venereology and Andrology, Faculty of Medicine, Sohag University, Egypt or refereed from Clinics of Ophthalmology, Faculty of Medicine, Sohag University, Egypt. This study has been conducted between January 2017 and October 2018. This study was approved by Research and Ethical committee at Faculty of Medicine, Sohag University. Informed consents were obtained from all patients after detailed clarification for the nature of the study.
The diagnosis of HZO was based on an established clinical diagnosis and confirmed in all patients by two dermatologists. According to Oxman et al.  and Gauthier et al.  who defined PHN as pain that persists for at least 3 months after the onset of HZ rash.
Every patient underwent a full evaluation by dermatologist and ophthalmologist to verify the diagnosis of HZO and to detect ocular manifestations.
All patients underwent a detailed medical history included; age, sex, education, occupation, marital status, residence, social class, special habits, past history of chicken pox, past history of HZ, history of receiving immunosuppressive drugs, history of medical illness, and history of psychological stress before eruption.
All patients underwent full clinical assessment of HZO disease included; site of the disease, pain, rash (onset, course, and duration of the disease), eye affections, visual outcomes after treatment, PHN, and posttreatment scar.
All patients received systemic antiviral drugs (for 7–10 days), NSAIDs and topical drugs for the cutaneous and eye lesions.
Statistical analysis has been performed using the IBM Statistical Package for Social Sciences, version 20.0 (SPSS Inc., Chicago, Illinois, USA). Quantitative data was presented as the mean±SD, and qualitative data was presented as frequency and percentages. Student’s t test was used for comparison between quantitative data of the study groups. P value less than 0.05 was considered statistically significant.

| Discussion|| |
To the best of our knowledge, this was the first study aimed to evaluate the demographic features, clinical presentations, and outcomes of HZO patients who attended Outpatient Clinics of the Dermatology, Venereology, and Andrology Department, Faculty of Medicine, Sohag University, Egypt.
Of 64 patients with HZO, 41 (64.1%) were females and 23 (35.9%) were males. This finding concurs with Tran et al.  who reported that distribution of HZO according to sex was ∼59.9% female and 40.1% male. Generally, females are exposed to more stressful conditions than males (menstruation, pregnancy, and lactation) that are the triggers for reactivation of latent VZV and also females are good observers to abnormal sensation they feel or abnormal rash.
In the current study, the mean age of male patients was 52.56±12.44 while the mean age of female patients with HZO was 53.14±14.24. Ghaznawi et al.  reported that HZO was more frequent in individuals between the ages of 60–69 years while Miserocchi et al.  found that HZO was more frequent in patients between the ages of 50–59 years.
In this study, HZO was more common among married male patients (87%) and married female patients (73.2%). Marriage is always associated with many social and economic troubles which expose the partners to more stressful conditions that impair the immunological status of the patients.
In the current study, 69.6% of male patients and 63.4% of female patients with HZO were educated. This study reported that detection of HZO associated with increase the level of education reflects that education may associated with more awareness of the disease that leading to a higher level of early seeking medical advice.
This study reported that HZO was a common in housewife females 85.4% which may be explained by that housewives are more liable to psychological problems and depression than working females whom are economically independent from their husbands. Depression may be influencing HZ risk through the mechanism of decreasing the cell-mediated immunity; depression was found to be associated with decline in VZV-specific cell-mediated immunity as measured by the VZV responder cell frequency .
In our study, 60.8% of male patients with HZO had nonofficial jobs (drivers, farmers, and workers). Exposure to environmental factors such as pollution, chemicals, sun, and stress (because they had not fixed salary) may explain higher incidence of HZO among these patients than others. The most common risk factors that can result in inadequate immune response to VZV reactivation at any age, including mental health, stress, comorbid infections (e.g. cytomegalovirus infection) and chemotherapy, and disease-related immunosuppression (e.g. HIV-AIDS) .
In the current study, 78% of female patients and 87% of male patients with HZO were from rural and suburban areas. Nowadays, the level of education and awareness increased in these areas in our community so they seek medical advice early.
This study found that 82.6% of male patients and 78% of female patients with HZO were of low and middle socioeconomic class; these both classes in our community suffer from many economic and social problems making them more liable for diseases than others.
The current study reported that 65.2% of male patients with HZO were current smokers. Tobacco is considered the most commonly used addictive substance in Egypt. Smoking has deleterious effects on both systemic and local immunity, which may lead to reactivation of latent virus. Smoking may particularly synergize with aging to increase the prevalence of HZO. Cigarettes, chemicals, and pesticides have been associated with increase the risk of HZ .
In the current study, 85.4% of female patients and 87% of male patients with HZO had no previous history of chicken pox. It may be related to the nonspecific symptoms and signs of chicken pox in most of the patients, so may pass unnoticed by parents beside that the disease is self-limited and most of these patients may consult general practitioners not dermatologists. de Melker et al.  found in a nonvaccinated population such as the Netherlands, the risk of acquiring a primary VZV infection is over 97% and most people contract varicella before the age of 5. Varicella infection is necessary for HZ .
In this study, none of the patients had history of previous attack of HZ which was similar to Marin et al.  who detected the personal history of previous HZ attack as a risk factor for current HZ was usually ignored, and recurrence of HZ was considered uncommon.
This study showed that 48.79% of female patients and 39.2% of male patients with HZO had history of medical systemic diseases (diabetes mellitus, hypertension, and renal transplantation). Opstelten et al.  showed that the main factors affecting epidemiology of HZO were epidemiology of associated systemic diseases, use of immunosuppressant drugs, and implementation of both the varicella and zoster vaccines.
In this study, only one female patient with HZO had history of receiving immunosuppressive drugs after renal transplantation (high doses of corticosteroid and azathioprine). Edell and Cohen  found immunosuppression and the immunosenescence of aging have been associated with an increased risk of developing HZ.
This study found that 53.7% of female patients and 47.8% of male patients with HZO had history of psychological stress before eruption. Lasserre et al.  detected that less consistency can be found regarding stress as a risk factor for HZ but Marin et al.  found that stress in the 3 months before HZ was considered a risk factor, but there was no evidence of a dose response.
This study found that HZO had acute onset and progressive course in all patients. The mean duration of HZO in male patients (5.56±1.23) was longer than in female patients (4.38±0.57).
In this study, the most common site of HZO was the left side in 73.2% of female patients and 78.3% of male patients.
This study reported that periorbital vesicular rash was presented in all patients which was inconsistent with Borkar et al.  who reported that dermatitis was the most common manifestation overall of HZO and more than 60% of the patients presented with dermatitis without any other manifestations.
All the patients had history of pain at time of presentation. Harding et al.  found that pain is common at presentation, occurring in 82.1% of patients and of those who were pain free at presentation 60% subsequently developed pain.
In current study, 29.2% of female patients and 43.5% of male patients with HZO developed ocular manifestations (conjunctivitis, keratitis, lid edema, and optic neuritis). Liesegang  reported 50–72% of patients with HZO had ocular involvement. Keratitis and conjunctivitis had been reported as common manifestations of HZO .
In this study, visual outcome after treatment was normal in 85.4% of female patients and 82.6% of male patients with HZO. Harding et al.  found that in the preantiviral era, 50% of patients with HZO developed ocular involvement. With antiviral therapy, lower frequencies of eye involvement had been reported, ranging from 2 to 29% . If patients are not treated promptly and aggressively, HZO with intraocular involvement may lead to significant visual impairment.
In this study, 31.7% of female patients and 30.4% of male patients with HZO developed PHN. PHN is the most common chronic complication of HZ infection and is seen in 9–45% of the patients . But, other studies reported that the rate of developing PHN ranged between 5.4 and 19.5% after all patients of HZ and ophthalmic location has been shown to be a risk factor for developing PHN ,, which may explain the slightly higher proportion of PHN found in this study. Also, this study found that the main risk factors of PHN are advanced age, the severity of acute zoster pain and ocular involvement.
In this study, post-HZO cutaneous scarring was presented in 70.7% of female patients and 43.5% of male patients. The incidence of scar increased in dark skin complexion, advanced age, immunosuppression, and severe extensive HZO eruption. El Hayderi et al.  reported HZ was associated with cutaneous scarring in 9.7% of all cases and was common in females 56.3% than males 43.7%.
The present study has several limitations. The sample size was small because this study has been performed on outpatients in the dermatology clinics. In addition, multicenter studies are required to give more factually results of the demographic features, clinical presentations, possible risk factors, and outcomes of HZO patients.
This study concluded that HZO is a common and potentially ruinous disease that may show a significant ophthalmic morbidity if not adequately diagnosed and treated.
