Diabetic ophthalmoplegia

We report a case of isolated left abducens nerve palsy accompanying a right thalamic infarct. The patient, a 43-year-old Malay male with newly diagnosed hypertension, diabetes mellitus, and dyslipidemia, initially reported binocular diplopia on left lateral gaze persisting for five weeks. Subsequently, he experienced acute left-sided body weakness and slurred speech for over one day. Clinical examination revealed restricted left eye lateral gaze (-3) with no relative afferent pupillary defect...

When pituitary metastasis (PM) invades the pituitary gland, it leads to impaired endocrine function and compression and infiltration of surrounding tissues, causing a series of clinical alterations. We presented seven patients with PM evaluated at neuro-ophthalmologic clinic and reviewed neuro-ophthalmological findings of 44 cases with PM in the English literature from 1979 to December 2022. The mean age at diagnosis was 58.1 years, and 45.1% were male. The mean latency period from primary cancer to the diagnosis of PM was 57...

Mucormycosis is a progressive and life-threatening disease that has been increasingly reported in patients infected by coronavirus diseases 2019 (COVID-19). We describe a case of rhino-orbital mucormycosis with central nervous system involvement resulting in bilateral blindness and intracranial extension in a patient with uncontrolled diabetes mellitus (DM) and mild COVID-19 infection. A 35-year-old obese male, recently diagnosed with DM, presented to the emergency department suffering from dizziness, headache, speech difficulty, and facial weakness...

PURPOSE: Ophthalmic manifestations of varying severity are often associated with systemic autoimmune conditions. Superior orbital fissure syndrome (SOFS) is a rare cranial neuropathy affecting nerves passing through the superior orbital fissure that causes a distinctive pattern of extraocular and pupillary findings. We report the coexistence of SOFS, relapsing polychondritis (RP) and Sjögren's syndrome (SS) in a 52-year-old female who presented with a past medical history of hypothyroidism, Raynaud's syndrome, and intermittent dry mouth and a 1-week history of worsening chemosis, proptosis, diplopia, and painful ophthalmoplegia...

This is the case of a 51-year-old woman with chronic progressive external ophthalmoplegia (CPEO) alongside some comorbidities in a low-resource setting. This report seeks to sensitise clinicians about this rare condition in order to increase their index of suspicion and avoid misdiagnosis.

A 41-year-old male with recently diagnosed diabetes mellitus type 2 presented with drooping of the left eyelid with double vision and was found to have an adduction deficit in the left eye and nystagmus in the abducting right eye during conjugated gaze: a left-sided internuclear ophthalmoplegia (INO). A medial longitudinal fasciculus (MLF) lesion was excluded exhaustively with brain imaging. The possibility of a pseudo-INO was considered. The autoantibody profile demonstrated positivity to acetylcholine receptor (AChR) antibody...

Introduction Mucormycosis (black fungus) is a rare opportunistic fungal infection commonly affecting immunocompromised individuals. There has been a surge in the number of these cases during the second wave of the coronavirus disease 2019 (COVID-19) in India. Mucormycosis has been reported to occur within a week or a few weeks post-recovery from COVID-19. The most common clinical manifestation of mucormycosis is rhino-orbital-cerebral mucormycosis (ROCM). At our tertiary care center, we initiated a prospective study to identify risk factors, study ocular manifestations, and explore medical and surgical management of orbital mucormycosis patients in the post-COVID-19 era...

PURPOSE: The aim was to evaluate patient profiles of rhino-orbital-cerebral mucormycosis (ROCM) cases with central retinal artery occlusion (CRAO) postcoronavirus disease 2019. DESIGN: A nonrandomized retrospective case-control study. METHODS: The ROCM cases presenting with CRAO were compared with a control ROCM group without CRAO at a tertiary care center. Demography, systemic status, clinical features, histopathology, imaging, and blood profile were assessed for any specific risk factors...

Rhino orbital Mucormycosis caused by filamentous fungus of mucoraceae family was considered a rare disease affecting immunocompromised and diabetics with ketoacidosis until the recent COVID 19 pandemic. We are presenting a series of six cases of Rhino orbital cerebral Mucormycosis with central retinal artery occlusion. All six cases had common history of COVID 19 infection in recent past with sinusitis, proptosis and total ophthalmoplegia with central retinal artery occlusion on presentation. MR imaging showed invasive pan sinusitis with orbital and cerebral involvement...

OBJECTIVE: To evaluate the extent of signal abnormality in impaired ocular motor nerves using high signal and spatial resolution MRI sequences and to discuss the involvement of inflammatory or microvascular impairment in patients with diabetic ophthalmoplegia. METHODS: We conducted a retrospective study of 10 patients referred for acute ocular motor nerve palsy in the context of diabetes mellitus from September 15th, 2021 to April 24th, 2022. 3T MRI evaluation included diffusion, 3D TOF, FLAIR, coronal STIR and post-injection 3D T1 SPACE DANTE sequences...

OBJECTIVE: To analyze the dynamics of symptoms in patients with COVID-19 associated sino-orbital mucormycosis. MATERIAL AND METHODS: We describe a series of 13 patients with COVID-19 associated sino-orbital mucormycosis aged 43 to 80 years diagnosed from August to October 2021. All of the patients had a severe disease and required noninvasive ventilation or intubation and administration of dexamethasone. 12 out of 13 patients (92.3%) suffered from diabetes mellitus...

Various complications of pituitary neuroendocrine tumors (PitNET) are reported, and an intratumor hemorrhage or infarct underlying pituitary apoplexy (PA) represents an uncommon, yet potentially life-threatening, feature, and thus early recognition and prompt intervention are important. Our purpose is to overview PA from clinical presentation to management and outcome. This is a narrative review of the English-language, PubMed-based original articles from 2012 to 2022 concerning PA, with the exception of pregnancy- and COVID-19-associated PA, and non-spontaneous PA (prior specific therapy for PitNET)...

The coronavirus disease 2019 (COVID-19) pandemic has led to the widespread use of steroids as a life-saving measure. In patients with preexisting diabetes, the therapeutic use of steroids coupled with poorly controlled sugar has led to a surge of mucormycosis. We report a rare case of orbital apex syndrome secondary to mucormycosis post-COVID-19. A 43-year-old female with poorly controlled diabetes mellitus presented with right eye complete ptosis one week post-recovery from COVID-19 infection. During COVID-19 hospitalization, she received a course of dexamethasone...

Large single mitochondrial DNA (mtDNA) deletion syndrome is a rare inborn error of metabolism with variable heteroplasmy levels and clinical phenotype among affected individuals. Chronic progressive external ophthalmoplegia (CPEO) is the most common phenotype in adults with this form of mitochondrial disease [J Intern Med. 2020;287(6):592-608 and Biomed Rep. 2016;4(3):259-62]. The common CPEO clinical manifestations are ptosis and ophthalmoplegia. More variable phenotypic manifestations of CPEO (CPEO plus) include involvement of the peripheral nervous system and myopathy...

PURPOSE: To determine the clinical presentation and risk factors associated with rhino orbital mucormycosis. INTRODUCTION: Mucormycosis is a rapidly progressive fungal infection caused by filamentous fungi in the Mucoraceae family. In large numbers, they release spores into the air, and humans get exposed through inhalation. The spores inoculate in the paranasal sinuses and nasopharynx and subsequently spread to the orbit and intracranial cavity. The present COVID-19 pandemic has witnessed a resurgence of rhino-orbital mucormycosis cases, mainly seen in patients with immunocompromised status...

PURPOSE: The aim was to evaluate patient profiles of rhino-orbital-cerebral mucormycosis (ROCM) cases with central retinal artery occlusion (CRAO) postcoronavirus disease 2019. DESIGN: A nonrandomized retrospective case-control study. METHODS: The ROCM cases presenting with CRAO were compared with a control ROCM group without CRAO at a tertiary care center. Demography, systemic status, clinical features, histopathology, imaging, and blood profile were assessed for any specific risk factors...

OBJECTIVES: An increased incidence of acute invasive fungal sinusitis associated with the recent COVID-19 pandemic has been observed, which is considered a public health concern. This study aims to detect the incidence, risk factors, causative agents, clinical presentations, outcomes, and susceptibility rate of various antifungals. METHODS: In this cross-sectional cohort study, a total of 30 patients showing acute invasive fungal rhinosinusitis following a COVID-19 infection were investigated...

Subperiosteal orbital hemorrhage usually occurs in the setting of facial or orbital trauma. Non-traumatic subperiosteal orbital hemorrhage (NTSOH) has rarely been reported in literature. The proposed mechanism of NTSOH is the transmission of sudden increase in cranial venous pressure to the orbital veins, which are valveless. We present a case of a 37 year old right-handed woman with a past medical history significant for type 1 diabetes, end-stage renal disease, peripheral artery disease and hypertension who developed NTSOH following an elective revision of a clotted right upper extremity arteriovenous fistula...

PURPOSE: Increased incidence of acute invasive fungal rhinosinusitis (AIFR) in the setting of COVID-19 is undeniable. This can be attributed to its effect on innate immunity and extensive use of corticosteroids. The goal of our study was to assess the orbital complications of AIFR and its management in the COVID-19 convalescent patients. METHODS: Our longitudinal prospective study included 45 patients with orbital complications of AIFR in recently recovered COVID-19 patients...

Mucormycosis is a serious, rapidly progressing, life-threatening, and sight threatening fungal infection frequently seen in diabetics and immunocompromised patients. We report a rare occurrence of rhino-orbital mucormycosis presenting as unilateral central retinal vein occlusion (CRVO) and no other ocular signs of infection in a 65-year-old diabetic male. The definitive diagnosis was made by nasal biopsy which confirmed broad branching aseptate fungal hyphae. The patient was treated with amphotericin B for mucormycosis and intravitreal anti-vascular growth factor (anti-VEGF) drug for macular edema...
