Thyroid eye disease (TED) characterizes by inflammation and remodeling of orbital tissues. Although the majority of pediatric TED is mild, some children present progressive and severe disease. The approach to severe disease in this group of patients, especially when noncortico-responsive, is challenging. The purpose of this work was to describe the effective use of tocilizumab as second-line therapy in steroid-resistant pediatric TED. A 13-year-old female with a history of Graves' disease presented with right eye proptosis for at least 8 months associated with mild pain on eye movements and ocular surface complaints. The ophthalmologic evaluation revealed Hertel exophthalmometry readings of 22 mm on the right eye (OD) and 19 mm on the left (OS). The remaining ophthalmic examination was unremarkable. Intravenous methylprednisolone pulses of 500 mg were initiated without any improvement after 4 treatments. Following multidisciplinary team discussion, therapy was switched to monthly tocilizumab injections at 4 mg/kg. Significant reduction of proptosis and resolution of pain and ocular surface complaints were noted immediately after the treatment switch. Exophthalmometry readings after the end of treatment that included 4 tocilizumab injections were 20 mm on OD and 19 mm on OS. No side effects were reported during the entire follow-up. Six months after treatment cessation, the patient remains stable, without any signs of orbitopathy relapse and no ophthalmologic complaints. This is the second case report showing the effectiveness of tocilizumab in pediatric TED and the first one showing its efficacy when steroids fail. Our results support the potential safety and efficacy of this immunosuppressor in children with TED. [ABSTRACT FROM AUTHOR]

We aim to report a case of a middle-aged woman with bilateral idiopathic elevated episcleral venous pressure (IEEVP) and its difficulties in the diagnostic approach. Particularly in this case, the atypical feature of ocular hypertension without glaucomatous optic nerve damage may be misleading. We present a 66-year-old woman with longstanding bilateral "red eyes." Clinical findings included bilateral episcleral vessel engorgement and tortuosity and raised intraocular pressure with open iridocorneal angles. Despite ocular hypertension, glaucomatous neuropathy was absent and confirmed by normal structural (optical coherence tomography) and functional (standard automated perimetry) tests. The systemic workup was unremarkable. Magnetic resonance angiography showed bilateral dilated superior ophthalmic veins. Cerebral digital subtraction angiography was requested, and no carotid-cavernous fistula (or other significant vascular findings) was identified. The diagnosis of IEEVP was assumed. In conclusion, our case highlights the systematic investigation necessary in cases of bilateral episcleral vessel engorgement and tortuosity and the possible differential diagnosis to be considered to rule out life-threatening causes of elevated episcleral venous pressure. It is important for clinicians to be aware of IEEVP even in patients with atypical features that despite significative ocular hypertension had no glaucomatous damage. [ABSTRACT FROM AUTHOR]

Introduction: Mucopolysaccharidosis type VI (MPS VI) is a rare inherited metabolic disorder, primarily attributed to the deficiency of the enzyme N-acetylgalactosamine-4-sulfatase, responsible for the degradation of dermatan sulfate and chondroitin-4-sulfate. Therefore, there is a widespread accumulation of partially degraded glycosaminoglycans. Corneal opacification is the hallmark ocular feature in the MPS. Retinal and scleral involvement in this MPS is extremely rare. The purpose of this work was to describe novel fundoscopic alterations present in patients with MPS VI. Case Presentation: This is a case series involving three non-related patients referred to our department from the Unit of Inherited Metabolic Diseases. Multimodal imaging was performed in every patient. Fundus photography and enhanced depth imaging optical coherence tomography (EDI-OCT) were performed. Multiple areas of yellow/orange patches were observed on fundus photography, corresponding to areas in which deposits of intermediate reflectivity in the EDI-OCT could be seen at the scleral level with associated choroidal thinning. This finding suggested the presence of scleral deposits of glycosaminoglycans. Conclusion: To our knowledge, this is the first case series in the literature encompassing patients with MPS VI with suspected deposits of glycosaminoglycans in the sclera. The better control of the systemic comorbidities, the increase in life expectancy, and the timely management of corneal disease have allowed the identification of new, late-onset ocular manifestations in MPS patients. In addition, new imaging techniques have introduced the possibility of better characterizing and understanding these manifestations. [ABSTRACT FROM AUTHOR]
