Herpes Zoster Ophthalmicus Clinical Presentation and Risk Factors for Lesion Recovery

Purpose

Herpes zoster ophthalmicus (HZO) causes trouble in patients' daily life and work. In severe cases, it may even lead to a decrease or loss of vision. To understand the demographic information and ocular symptoms of hospitalized patients with HZO, and to find potential factors related to improvement time of skin rash and duration of ocular symptoms at discharge, we design this study.

Patients and Methods

This is a retrospective study. All patients diagnosed with HZO who were hospitalized in the Department of Dermatology of a hospital in Chongqing, China from January 1, 2015 to December 30, 2021 were included in this study. A total of 189 patients were included in this study. Clinical manifestations of the disease during hospitalization, improvement time of ocular skin lesions, and whether ocular skin lesions disappeared completely at discharge were recorded.

Results

The most common ocular symptom was eyelid swelling (92.6%), followed by eye pain (48.7%). The most common ocular sign was conjunctivitis (78.3%), followed by keratitis (15.9%). There were 149 cases without residual ocular symptoms and 40 cases with residual ocular symptoms. There was no statistically significant difference in demographic characteristics between the two groups (P>0.05). Age ≥70 years (B=0.381, -0.061~0.022, P=0.005), use of glucocorticoids (B=0.260, 0.024~0.496, P=0.031), and use of topical antiviral drugs (B=0.380, 0.054~0.705, P=0.023) were factors affecting the time interval from admission to improvement of skin rash. Tearing (HR, OR=4.827, 1.956~11.909, P<0.001) and blood urea nitrogen (OR=0.787, 0.620-1.000, P=0.050) were factors influencing residual ocular symptoms.

Conclusion

This study could help clinicians gain a deeper understanding of the clinical manifestations and partial influencing factors of HZO patients, which may contribute to future clinical work.

Ocular manifestations of dermatological diseases part I: infectious and inflammatory disorders

Skin and eyes share a common embryological origin from the embryonic surface ectoderm. Ocular manifestations are one of the most important and common associations of dermatological diseases. Currently, there are few comprehensive reviews of the ocular manifestations of dermatological diseases. We have reviewed more than 40 published articles related to the ocular manifestations of the most important dermatological diseases. The search included Pubmed, Google Scholar, and Cochrane databases from 2014 to 2019. This review was divided into three parts including infections, inflammatory, genetics, connective tissue, autoimmune, neoplasms, and drug-related disorders. We excluded metabolic, endocrine, and nutrition-related dermatological diseases. The relationship of ocular manifestations and dermatological diseases is important to recognize for appropriate management since many dermatological diseases can manifest initially with ocular findings. In this part, we summarized the most common and significant ocular findings in infectious and inflammatory dermatological disorders with appropriate referral recommendations to ophthalmology.

[Anterior Uveitis: Clinic, Diagnostic Procedure and Treatment Options]

Anterior uveitis involves inflammation of the iris and/or ciliary body and is the most common intraocular inflammation in ophthalmological practice. It can be attributed to an infectious or immune-mediated genesis or be associated with systemic diseases. Anamnesis and (guiding) findings during the slit lamp examination often already provide important information on pathogenesis and thus on further diagnostic clarification and therapy. This includes the assessment of laterality, acute or chronic course of the disease and morphological criteria (granulomatous/non-granulomatous). The guideline-compliant procedure recommends further diagnosis with targeted laboratory diagnostics and, if necessary, consultative examinations if the disease recurs. This is important in order to pursue a targeted treatment approach and to recognize comorbidities.

Virus-Induced Anterior Uveitis (VIAU) in Immunocompromised Patients

PURPOSE

To describe the clinical characteristics, diagnosis, and treatment of VIAU in immunocompromised patients.

METHODS

A critical review of literature was performed.

RESULTS

Diagnosis and treatment of VIAU in immunocompromised patients may be a challenge due to atypical clinical-courses, severe presentations, and more frequent recurrences. A conclusive diagnosis can be made by aqueous-humour PCR-analysis. Visual prognosis depends on early diagnosis and prompt treatment. Frequent ocular examinations are recommended in HIV patients with CD-4-counts below 100 in order to rule out opportunistic ocular coinfections. It is essential to bear in mind the potential side-effects of therapeutic interventions and consider the possibility of Immune Recovery Uveitis (IRU) in eyes with treated viral retinitis after the initiation of HAART.

CONCLUSIONS

Early diagnosis and treatment of VIAU in immunocompromised patients can be achieved with high suspicion, recognizing clinical features, and obtaining specimens for molecular diagnostic testing in order to avoid usually severe ocular morbidity.
