A Case of Pharmacologic Anisocoria in Systemic Glycopyrrolate Use from Presumed Local Ocular Inoculation.

Anisocoria is a common finding in ophthalmic clinical practice. History taking and examination is critical in appropriately diagnosing and managing anisocoria, as the differential can be extensive ranging from benign to life-threatening entities. This case discusses the presentation of a 22-year-old female with a history of myopia and hyperhidrosis who presented with pharmacologic anisocoria which was presumed to be from inadvertent topical exposure to conventional glycopyrrolate tablets. To our knowledge, pharmacologic mydriasis from exposure to residue from conventional glycopyrrolate tablets has not been reported in the English literature. This case highlights the importance of medication and contact lens handling with anticholinergic agents.

Aseptic Orbital Cellulitis as a Complication of Suprachoroidal Hemorrhage.

Suprachoroidal hemorrhage is a rare and potentially devastating clinical entity seen in individuals on anticoagulation presenting with severe unilateral eye pain, sudden vision loss, and elevated intraocular pressures. Herein, we report the first case of aseptic orbital cellulitis caused by recurrent spontaneous suprachoroidal hemorrhage. This case highlights an example of non-infectious orbital cellulitis arising from choroidal pathology in the setting of uncontrolled intraocular pressures and recurrent intraocular bleeding. Surgical intervention with blood drainage should be considered to prevent complications and preserve the globe.

Ectopic orbital brain tissue: a case report with radiographic and clinical review.

Orbital heterotopic brain tissue is a rare entity with heterogenous clinical features requiring a multi-faceted diagnostic approach. The authors present a case of ectopic orbital brain tissue in an infant with a comprehensive literature review to highlight the radiographic findings of these lesions. Imaging findings are variable but describe well-circumscribed homogenous lesions with variable enhancement, without communication intracranially. The combination of computed tomography and magnetic resonance imaging can identify associated bony abnormalities, lesion-specific features, and effects on surrounding structures, which in combination with the clinical exam can be a valuable diagnostic and surveillance tool. Although ectopic orbital brain tumors are benign with excellent outcomes following complete resection, conservative management with observation and serial imaging may be an alternative method of management in patients with mild, non-vision threatening, non-distorting tumors.

Outcomes of Patients With Thyroid Eye Disease Partially Treated With Teprotumumab.

PURPOSE: In response to the coronavirus (COVID-19) pandemic, teprotumumab production was temporarily halted with resources diverted toward vaccine production. Many patients who initiated treatment with teprotumumab for thyroid eye disease were forced to deviate from the standard protocol. This study investigates the response of teprotumumab when patients receive fewer than the standard 8-dose regimen. METHODS: This observational cross-sectional cohort study included patients from 15 institutions with active or minimal to no clinical activity thyroid eye disease treated with the standard teprotumumab infusion protocol. Patients were included if they had completed at least 1 teprotumumab infusion and had not yet completed all 8 planned infusions. Data were collected before teprotumumab initiation, within 3 weeks of last dose before interruption, and at the visit before teprotumumab reinitiation. The primary outcome measure was reduction in proptosis more than 2 mm. Secondary outcome measures included change in clinical activity score (CAS), extraocular motility restriction, margin reflex distance-1 (MRD1), and reported adverse events. RESULTS: The study included 74 patients. Mean age was 57.8 years, and 77% were female. There were 62 active and 12 minimal to no clinical activity patients. Patients completed an average of 4.2 teprotumumab infusions before interruption. A significant mean reduction in proptosis (-2.9 mm in active and -2.8 mm in minimal to no clinical activity patients, P < 0.01) was noted and maintained during interruption. For active patients, a 3.4-point reduction in CAS ( P < 0.01) and reduction in ocular motility restriction ( P < 0.01) were maintained during interruption. CONCLUSIONS: Patients partially treated with teprotumumab achieve significant reduction in proptosis, CAS, and extraocular muscle restriction and maintain these improvements through the period of interruption.

Sebaceous Carcinoma of the Eyelid: Proposed Nomenclature for Multifocal and Multicentric Disease.

PURPOSE: To review clinical presentations of periocular sebaceous carcinoma (SC) and introduce standardized nomenclature for multicentric and multifocal disease presentation. METHODS: A comprehensive PubMed/Medline search was conducted to identify all articles reporting periocular multicentric or multifocal SC presentations. The authors also highlight an additional case of SC presenting with 2 clinically distinct tumor foci and complete secondary invasion of the lacrimal gland. RESULTS: This review summarizes clinical presentations of periocular SC exhibiting discrete foci of microinvasion reported in the literature. Discrete microinvasion was associated with high rates of misdiagnosis (80%), simultaneous involvement of both upper and lower eyelids (80%), pagetoid spread (80%), multinodular growth (33%), local tumor spread (60%), previous eyelid manipulation (40%), and local recurrence (40%). Eyelid multifocality with clinically discrete nodules (42%) was associated with more advanced disease including orbital extension and regional invasion (80%). CONCLUSIONS: Despite previous reported associations with poorer outcomes, there is no consensus in the definition or nomenclature for discrete microinvasive or clinical disease presentations in periocular SC. The authors recommend defining multicentric disease as discrete foci of microinvasive tumor with basement membrane disruption and multifocal disease as discrete clinically evident nodules involving both the upper and lower eyelids. Differentiating between discrete microinvasive (multicentric) and clinically nodular (multifocal) disease may improve risk stratification to most accurately identify patients who require more aggressive management and surveillance.

Varicella Zoster Aseptic Meningitis Presenting as an Atypical Mucocutaneous Eruption Involving All Three Divisions of the Trigeminal Nerve.

Herpes zoster involving all three divisions of the trigeminal nerve is extremely rare and may pose a diagnostic challenge, especially in young and immunocompetent patients. We present a unique case of herpes zoster involving all three divisions of the trigeminal nerve and illustrate that this uncommon eruption can be a presenting sign of varicella zoster aseptic meningitis. This case emphasizes the importance of fundamental morphology recognition, particularly its ability to aid in clinical diagnosis and its potential to decrease patient morbidity and mortality by expediting the initiation of appropriate treatment.

Utilizing a mobile platform to obtain quantitative measurements of exophthalmos.

PURPOSE: This study introduces a novel exophthalmometry method utilizing a mobile platform to obtain calibrated quantitative measurements of globe position and compares its reliability to Hertel exophthalmometry. METHODS: A prospective, comparative study included 50 patients (99 eyes) for a total of 594 mobile measurements. Healthy individuals from the community in Augusta, Georgia, and individuals from a routine oculoplastics clinic at Mayo Clinic in Rochester, Minnesota, were included to represent variety within the population. The main outcome was the inter-modality correlation and agreement between Hertel and mobile exophthalmometry, and the intra-observer and inter-observer reliability with repeated mobile measurements. RESULTS: There was no significant difference in the measurements obtained by Hertel exophthalmometry and mobile exophthalmometry. There was a strong linear correlation between Hertel and mobile exophthalmometry with a Pearson Correlation Coefficient of 0.910 and 0.888 for the right and left eyes, respectively (p < .001, 2-tailed). Bland-Altman plot analysis showed excellent agreement between the two modalities. The mobile platform demonstrated high intra-observer reliability with a Cronbach's alpha of 0.992 and 0.985 for the right and left eyes. An intraclass correlation coefficient of 0.992 (95% CI: 0.987-0.995) for the right eye and 0.986 (95% CI: 0.978-0.991) for the left eye demonstrated excellent reliability between observers. CONCLUSIONS: Mobile exophthalmometry may be a promising tool for obtaining calibrated quantitative measurements of globe position for situations in which Hertel exophthalmometry is not available. The strong correlation and excellent agreement between Hertel and mobile measurement suggest that mobile exophthalmometry can yield reliable and accurate measurements.

Immunoexpression of 5-methylcytosine (5mc) in Bone Marrow Haematopoietic Cells in Patients with Myelodysplastic Syndromes.

Myelodysplastic syndromes (MDS) are biologically and clinically heterogenous groups of clonal haematopoietic stem cell diseases characterized by ineffective haematopoiesis and peripheral blood cytopenia, with a variable tendency to transform within acute leukaemia (AL). DNA hypermethylation and hypo-methylation are associated with cancer. Thus, the hypermethylation of DNA is essential for the molecular pathophysiology of MDS by inactivating genes involved in cell growth, differentiation and apoptosis. It was documented that the 5-methylcytosine (5mc) immunostaining score of BM haematopoietic mononuclear cells is higher in MDS patients than in a normal control group, and that the prognosis of the disease significantly correlated with global DNA methylation, age and IPSS score. In our study, we analysed the immunocytochemical expression of 5mc in bone marrow (BM) mononuclear cells from 13 MDS patients and a control group consisting of 13 patients with anaemia of chronic disease. The immunopositivity of 5mc BM mononuclear cells was statistically significantly higher in our MDS patients than in patients with anaemia of chronic disease. In most MDS patients (11 out of 13), a higher 5mc immunopositivity of BM mono-nuclear cells (above 10%) was found. Our results are in concordance with data from literature observing that a higher percentage of 5mc immunopositive BM mononuclear cells is documented in MDS patients.

Treatment Refractory Brachioradial Pruritus Treated with Topical Amitriptyline and Ketamine.

Brachioradial pruritus is an uncommon chronic neurocutaneous condition that often presents as extreme itching, burning or tingling on the dorsolateral aspect of the arm. The lack of primary skin lesions in brachioradial pruritus in addition to its poorly established pathophysiology can often lead to both diagnostic and therapeutic challenges for many physicians. Here, we present a case of brachioradial pruritus and the unique combination of topical amitriptyline and ketamine as an effective therapy, including a brief review of the literature on similar such cases.

Adenoid cystic carcinoma of the lacrimal gland metastatic to the kidney: case report and review of the literature.

INTRODUCTION: Adenoid cystic carcinoma (ACC) is a malignant neoplasm that arises within secretory glands. It rarely occurs in the lacrimal gland. Kidney metastases are very rare. CASE PRESENTATION: We report a case of a 76-year-old female patient treated with right radical nephrectomy because of the tumour mass of the right kidney. Well-circumscribed, firm, grey mass was found on the lower pole of the kidney. Histologically, tumour was considered to be ACC. Retrospective history data showed ACC of the lacrimal gland surgically treated 14 years before with metastasis to the lung operated seven years before. Our diagnosis was metastatic ACC to the kidney. CONCLUSION: ACC has a remarkable capacity for recurrence. To our knowledge, in the English-speaking area (PubMed), 10 cases of ACC metastatic to the kidney have been described to date, and this is the second reported case of kidney metastasis from primary lacrimal ACC.
