ABSTRACT

INTRODUCTION: Virological diagnosis of anterior ocular herpetic disease (AOHD) is essential for the management of these often-chronic pathologies that may require long-term therapy. PCR has become the gold standard, but the type of sampling (tears, corneal scraping, aqueous tap) has not been standardized. In this study, we studied the technique of tear sampling for the diagnosis of AOHD. MATERIALS AND METHOD: We retrospectively analyzed the medical files of patients with a positive tear sample (Schirmer strip) for herpes simplex 1 virus (HSV-1) in the Department of Ophthalmology of Paris-Saclay Bicêtre Hospital between January 2018 and December 2020. We studied the clinical and virological characteristics (viral loads) of these cases of proven AOHD. RESULTS: Thirty-six samples (33 patients) were included: 12 epithelial keratitis, 9 stromal HSK with ulceration, 5 uveitis, 4 stromal HSK without ulceration, 3 blepharitis, 1 endothelial HSK, 1 neurotrophic keratitis, and 1 conjunctivitis. The mean viral load was 3.9×105 copies/mL. Viral load was higher in cases of corneal ulceration (5.2×105±9.4×105 versus 1.2×102±1.7×102 copies/mL, P<1×10-4). There was no significant difference between primary episodes and relapses. CONCLUSION: Tear sampling using Schirmer strips is a simple, non-invasive method that can be useful for the virological diagnosis of various clinical forms of AOHD.

ABSTRACT

PURPOSE: To assess the severity of dry eye disease in patients with blepharospasm (BEB) before (control) and after injection of botulinum neurotoxin A (BoNT/A). DESIGN: Cross-sectional study. METHODS: Patients with clinically diagnosed BEB and no known history of dry eye syndrome prior to the onset of the disease, before (controls) or after injection with one of the three available types of BoNT/A: onabotulinumtoxinA (Botox®; Allergan, Irvine, CA, USA), abobotulinumtoxinA (Dysport®; Beaufour Ipsen Pharma SAS, Paris, France) or incobotulinumtoxinA (Xeomin®; Merz Pharma GmbH, Frankfurt, Germany) every 3 months. Tear osmolarity and Schirmer's I-test were measured at the first visit for non-treated BEB patients as controls and 3 months after BoNT/A injection. RESULTS: The study consisted of 101 BEB patients (86 females, 15 males) with a mean age of 67 years (range 30-86 years). Seventeen patients were untreated, 26 treated with onabotulinumtoxinA, 23 treated with abobotulinumtoxinA and 35 treated with incobotulinumtoxinA. Post-injection mean tear osmolarity was not significantly higher among patients treated with onabotulinumtoxinA, abobotulinumtoxinA, or incobotulinumtoxinA (P=0.65, P=0.92, and P=0.15, respectively), compared to controls, remaining less than 308 mosm/mL. Mean Schirmer's I-test results remained under 5mm and did not vary between the four groups. CONCLUSIONS: The results clearly demonstrate that reduced tear secretion appears to be present in BEB patients even prior to treatment. This decreased lacrimal secretion was not correlated with hyperosmolarity. Clinicians should proactively treat dry eye syndrome in conjunction with management of the blepharospasm.

ABSTRACT

INTRODUCTION: Hemifacial spasm (HFS) is an involuntary contracture of the facial muscles innervated by the ipsilateral facial nerve. We studied the etiology of these HFS. MATERIALS AND METHODS: This retrospective study included 233 patients with HFS who came to the ophthalmologist for quarterly botulinum neurotoxin A injection. Of these, we analyzed the 198 patients for whom MRI scans were performed. We recorded patient clinical data and clarified the etiology of their HFS. RESULTS: The 198 patients (62.6% women) had a mean age of 55.7±14years. An etiology was found in 52.5% of cases. In 34.5% of HFS, MRI revealed vascular compression where the facial nerve emerged from the brainstem. We specify the arteries involved. Brain tumors accounted for 1.5% of cases. MRI was normal in 64.5% of cases. In these secondary cases of HFS, we found 8.5% peripheral facial palsy, 4% post-traumatic HFS and 4% secondary to an eye injury. Stress was found in 17% of patients. DISCUSSION AND CONCLUSION: This study illustrates the need for MRI with attention to the posterior fossa in the work-up of HFS in order to identify primary HFS associated with vascular compression of the facial nerve and to rule out a rare but serious posterior fossa tumor. The treatment of HFS is based on quarterly injections of botulinum neurotoxin/A (NTBo/A), the three brands of which have market approval. The injection pattern and frequency is customized according to the results. In cases of insufficient response to injections of NTBo/A, neurosurgical microvascular decompression may be considered for cases of primary HFS.

ABSTRACT

PURPOSE: The goal of this study is to determine a link between benign essential blepharospasm and Sjogren's syndrome by analyzing the presence of extractable nuclear antigens in this population. METHODS: Seventy-two patients with benign essential blepharospasm (BEB) were included in this study. We eliminated patients with hemifacial spasm or blepharospasm secondary to corneal pathology. We collected the values of the Schirmer I test and the results of the anti-SSA and anti-SSB antibodies. RESULTS: Our study included 72 patients (144 eyes) whose 62 women (86.1%). Mean age was 74.3 years±10.73. Average Schirmer I test was 3.14mm±4.00mm. Five women (8% of this female population) had positive anti-SSA and SSB antibodies. Their mean age was 65.66 years±13.24 whereas the negative antibody patients had an average age of 75.42±9.27. There was no significant difference between their Schimer I test and the Schirmer I of negative antibody population. CONCLUSION: This study illustrates the possible association between the presence of Sjögren's syndrome and the occurrence of a BEB justifying the search for anti-SSA and anti SSB in blepharospasm patients.

ABSTRACT

PURPOSE: To study whether there is an association between benign essential blepharospasm and Sjögren's syndrome by analyzing the presence of antibodies to extractable nuclear antigens in this population. METHODS: Seventy-two patients with benign essential blepharospasm (BEB) were included in this study. We excluded patients with hemifacial spasm or blepharospasm secondary to known corneal pathology. We recorded results of Schirmer I testing as well as levels of anti-SSA/Ro and anti-SSB/La antibodies. RESULTS: Our study included 72 patients (144 eyes), of which 62 (86.1%) were women. The mean age was 74.3±10.73 years. The mean Schirmer I test result was 3.14±4.00mm. Five women (8% of this female population) were found to have positive anti-SSA/Ro and anti-SSB/La antibodies. Their mean age was 65.66±13.24 years, while the mean age of the antibody-negative patients was 75.42±9.27 years. There was no statistically significant difference between the Schirmer I tests of the antibody positive and negative patients. CONCLUSION: This study demonstrates a possible association between Sjögren's syndrome and benign essential blepharospasm, justifying anti-SSA/Ro and anti-SSB/La testing in these patients.
