PURPOSE
This study aims to report correlations between thyroid-stimulating immunoglobulin(TSI) and both clinical and radiological parameters in recent-onset symptomatic thyroid eye disease(TED) patients.
METHODS
A prospective cohort study of TED patients managed at the Chinese University of Hong Kong from January 2014 to May 2022. Serum TSI levels were determined with the functional assay. Outcomes included the clinical activity score(CAS), marginal reflex distance1(MRD1), extraocular muscle motility restriction(EOMy), exophthalmos, and diplopia. The radiological assessment included cross-sectional areas and signal of extraocular muscles on STIR-sequence MRI.
RESULTS
A total of 255(197female) treatment-naïve patients, with an average onset age of 50±14 years, were included. Elevated pre-treatment TSI level was observed in 223(88%) patients. There was a weak positive correlation between TSI and CAS(r=0.28, P=0.000031), MRD1(r=0.17, P=0.0080), and the size of the levator palpebrae superioris/superior rectus complex(r=0.25, P=0.018). No significant correlation existed between TSI and STIR signals. The AUC and optimal cut-off value for clinical active TED were 0.67(95% confidence interval:0.60-0.75) and 284%(Specificity:50%, sensitivity:85%). 64 patients received intravenous methylprednisolone (IVMP) during the study interval, and they had a higher baseline TSI level than those who did not have IVMP(P=0.000044). Serial post-IVMP TSI among the 62 patients showed a significant reduction compared to the baseline level(P<0.001). Both the baseline and post-IVMP TSI levels, and percentages of TSI changes were comparable between patients who responded and non-responded to the first course of IVMP.
CONCLUSION
TSI can be a serum biomarker for the diagnosis, prognosis, and treatment response of TED. Further validation should be further warranted.

Cavernous sinus dural arteriovenous fistula can cause cerebral edema and hemorrhage due to cortical venous reflux and congestion. Understanding complex venous reflux and drainage routes is crucial for treatment planning. Here, we present a case of a cavernous sinus dural arteriovenous fistula with cortical venous reflux via two separate terminations of the telencephalic veins caused by an aplastic basal vein of Rosenthal. The patient presented with diplopia and eye redness and was diagnosed with a Cognard type IIa + b cavernous sinus dural arteriovenous fistula. The shunt was supplied by the dural branches of the internal and external carotid arteries. Multiple shunt points involving the intercavernous sinus and the medial aspect of the left cavernous sinus were identified, with drainage into the supraorbital and intracranial veins, including two separate terminations of the telencephalic veins, one leading to the laterocavernous sinus via the superficial middle cerebral vein and the other to the cavernous sinus via the uncal vein, resulting in basal ganglia venous congestion in the absence of the basal vein of Rosenthal. During transvenous embolization, the intracranial veins, cavernous sinus, and intercavernous sinus were obliterated using a double-catheter technique with a combination of coils and liquid embolics. Telencephalic venous variations can lead to cavernous sinus drainage into the basal ganglia and orbitofrontal brain. This unique drainage pattern underscores the importance of recognizing anatomical variations when managing cavernous sinus dural arteriovenous fistula.

INTRODUCTION
Diffuse large B-cell lymphoma (DLBCL) is a prevalent subtype of non-Hodgkin lymphoma (NHL) affecting predominantly elderly individuals.
CASE DESCRIPTION
A 68-year-old man with a history of hypertension, hyperlipidaemia and a small pituitary gland tumour presented with sudden-onset binocular diplopia and right-eye blurry vision. A magnetic resonance imaging (MRI) of the brain revealed enhancing soft tissue in the right superolateral orbit inseparable from the lacrimal gland, extending medially to the right superior rectus muscle and soft tissue. Further scanning showed widespread metastasis to the bilateral retroperitoneal lymph nodes, adrenal gland, spine and lymph nodes in the neck. A biopsy of the lacrimal gland confirmed DLBCL.
CONCLUSION
Primary lacrimal gland DLBCL is a rare and delayed diagnosis that often stems from the resemblance of its clinical manifestations to more benign conditions such as dacryocystitis, dacryostenosis or mucocele. Timely recognition and accurate diagnosis are essential for initiating appropriate treatment and improving patient outcomes.
LEARNING POINTS
Lacrimal sac lymphomas represent diagnostic challenges due to their rarity, non-specific symptoms and frequent misdiagnoses as benign pathologies, hence it is crucial to include this in the differential diagnosis.Timely recognition and accurate diagnosis are important in improving outcomes for lacrimal sac lymphomas.

BACKGROUND
Oculomotor nerve palsy is often associated with diabetes mellitus or caused by compression by a cerebral aneurysm. Here, we report a rare case of oculomotor nerve palsy caused by compression by the posterior cerebral artery (PCA).
CASE DESCRIPTION
A 66-year-old woman suddenly developed diplopia and right blepharoptosis. Her symptoms suggested incomplete right oculomotor nerve palsy. Magnetic resonance imaging showed that a sharp curve in the right PCA had compressed the right oculomotor nerve. Microvascular decompression surgery was performed. Intraoperative findings showed that the P2 portion of the PCA had caused an indentation in the oculomotor nerve in the prepontine cistern. The transposition of the PCA with a prosthesis released the pressure. After the operation, her right blepharoptosis gradually improved. She had fully recovered by 48 days after the operation.
CONCLUSION
Neurovascular compression (NVC) is recognized as the cause of hemifacial spasms, trigeminal neuralgia, and glossopharyngeal neuralgia. This case report demonstrated that NVC can also cause oculomotor nerve palsy. A high index of clinical suspicion can detect vascular compression of the oculomotor nerve. Prompt diagnosis and appropriate surgical management can achieve clinical improvement.

BACKGROUND
The radiographic presentation of the primary intraosseous cavernous hemangiomas (PICHs) is nonspecific. We report a case of clival PICH mimicking a chordoma with a literature review.
CASE DESCRIPTION
A 57-year-old woman presented with diplopia that started a few days before the presentation. She had transient diplopia at the right lateral gaze and upper gaze with normal eye movement. The symptoms disappeared spontaneously 1 week later. She had no other complaints or neurological deficits. Computed tomography revealed an intraosseous mass lesion and bone erosion of the middle and lower clivus, extending laterally to the right occipital condyle. Magnetic resonance imaging (MRI) showed hyperintense and hypointense components on T2- and T1-weighted images, respectively. The lesion was larger than on MRI performed 10 years earlier. Chordoma or chondroma was considered a possible preoperative diagnosis. An endoscopic transsphenoidal approach removed the tumor. In the operating view, the lesion appeared as "moth-eaten" bony interstices filled with vascular soft tissue. Histologically, an intraosseous cavernous hemangioma was diagnosed.
CONCLUSION
Diagnosis before surgery is difficult without characteristic radiographic findings. When making a differential diagnosis of malignant skull lesions, PICH should be considered.

BACKGROUND
Botulism has not been previously reported in the Kingdom of Saudi Arabia. This rare and sometimes fatal foodborne illness is caused by neurotoxins and primarily results from consuming home-canned fruits, vegetables, dairy, and seafood products & it can lead to paralysis.
OBJECTIVE
The purpose of this study was to evaluate the clinical features of patients who developed botulism in Riyadh in 2024 after consuming mayonnaise from a well-known local chain of restaurants in Riyadh, Saudi Arabia.
METHODS
We conducted a retrospective analysis of medical records and interviewed patients or their attendants for all hospitalized cases of foodborne botulism at Riyadh First Health Cluster. For each patient, a standard case report form was completed, containing information on demographics, clinical aspects, botulinum test results, and type of exposure. Descriptive statistics were applied to assess the data. During the outbreak, nineteen patients with foodborne diseases were admitted to Riyadh First Health Cluster Hospitals. Following thorough physical examinations, botulism was suspected in each case.
RESULTS
Eight of the 19 suspected foodborne illness patients fully satisfied the botulism case definition requirements set forth by the Saudi Arabian Public Health Authority (Weqaya). Among these eight patients, 2 (25%) were male and 6 (75%) were female, with a mean age of 23.25 ± 9.29 years (range: 12-38 years). The incubation period for our patients was 36.25 ± 26.26 h. Notable symptoms included dysphagia in all eight patients (100%), dysarthria, generalized weakness, nausea and vomiting in seven patients (88%), diplopia in four patients (50%), and stomach discomfort in three patients (38%). Of the eight cases, six required intubation, one mimicked brain death, and two were stable. The presence of Clostridium botulinum spores as the cause of the outbreak was confirmed by detecting botulinum spores in contaminated food.
CONCLUSION
Diplopia and dysarthria were the most common early sign of botulism. Early manifestations may include respiratory symptoms without any musculoskeletal symptoms. or nausea, vomiting and disorientation.

Tuberculosis is a worldwide health concern with a wide range of clinical manifestations. Rarely, it can involve the central nervous system in the form of tuberculomas. Although cranial nerve palsies or localized neurological signs are the most frequent presentations of tuberculoma, isolated sixth nerve palsy is unusual and rare. We report the case of a 17-year-old female who presented with isolated sixth nerve palsy, an unusual early manifestation of intracranial tuberculoma. We established the diagnosis through clinical, radiological, and laboratory evaluations and successfully managed the patient with antitubercular therapy. This case highlights the importance of considering tuberculoma as a differential diagnosis in cases of isolated cranial nerve palsies, especially in regions with a high prevalence of tuberculosis.

INTRODUCTION
Acute acquired concomitant esotropia (AACE) is an uncommon type of strabismus that occurs due to interruption of fusion. Limited data are available on AACE from Asian countries especially from the Southeast Asian region. We aim to describe the clinical profile and surgical outcomes of AACE patients treated in a tertiary hospital in Malaysia.
MATERIALS AND METHODS
We conducted a retrospective study of 20 patients aged 3-26 years who were diagnosed with AACE and attended Hospital Universiti Sains Malaysia, Kelantan, Malaysia, between January 2020 and June 2022 with follow-up periods a minimum of 12 months. Demographic data, clinical features, neuroimaging, surgical intervention, and final ocular alignment outcomes were recorded.
RESULTS
The mean age of onset was 9.7±6.6 years. There were equal numbers of males and females in this study. Hypermetropia (45%) was the leading refractive error. Angle of deviation of 50 PD and more was documented in 50% of the patients at distance, and 70% of the patients at near fixation. Fifty per cent had an absence of stereoacuity at presentation. Neuroimaging was performed on 13 patients (65%), and two patients had intracranial pathology. All patients underwent bilateral medial rectus recession during primary surgery. Eighteen patients (90%) experienced excessive near work-related activities for >4 hours per day, and 19 patients (95%) achieved good ocular alignment, restoration of stereoacuity and resolved diplopia after the surgical intervention.
CONCLUSION
The mean age of onset was 9.7±6.6 years. Almost half of our patients had uncorrected hypermetropia. Furthermore, 90% of patients had excessive near-work activities, and 95% achieved good post-surgery alignment.

BACKGROUND
A carotid-cavernous sinus fistula (CCF) is an abnormal communication between the internal carotid artery and/or the external carotid artery and the cavernous sinus. There is a paucity of information on the ophthalmic outcomes of endovascular treatment for CCF in the Philippines.
OBJECTIVES
This study aimed to describe the clinical experience of CCF in our institution in order to further our understanding of the disease. This study described the demographic profile, risk factors, and clinical features of patients with CCF, and compared the data of patients according to the type of CCF. The study discussed the changes in clinical features over time in CCF patients who chose not to undergo endovascular treatment. The study also discussed the clinical outcomes of CCF patients who underwent endovascular treatment and compared the clinical outcomes to CCF patients who did not undergo endovascular treatment.
METHODS
A retrospective cohort study design was performed using a medical record review of patients clinically diagnosed with CCF from January 2011 to June 2019.
RESULTS
One hundred twenty medical records of patients diagnosed with CCF were included. Based on angiographic findings, patients were grouped according to type of CCF, with 86 patients in Group 1 or Direct CCF, 23 patients in Group 2 or Indirect CCF, and 11 patients in Group 3 or Mixed type of CCF. The patients were also grouped according to treatment, with 109 patients in Group A, or patients who did not undergo endovascular treatment, and 11 patients in Group B, or patients who underwent endovascular treatment. There was a male predominance in CCF, most occurring in the age range of 26 to 35 years. Risk factors for CCF were trauma and hypertension. Clinical features included the presence of blurring of vision, proptosis, corkscrewing of conjunctival vessels, extraocular movement limitation, diplopia, audible bruit, elevated intraocular pressure, and pulsation. Findings on Computed Tomography scan included dilated superior ophthalmic vein, proptosis, and enlarged extraocular muscles. Direct CCF (Group 1) occurred mostly in males, with mean age of 39.1 years, and with trauma as the major risk factor. Indirect CCF (Group 2) occurred mostly in females, with mean age of 52.1 years, and with hypertension as the major risk factor. Regardless of the type of CCF, patients who did not undergo endovascular treatment can exhibit spontaneous improvement or worsening of clinical features. Patients who underwent endovascular treatment generally had favorable clinical outcomes, manifesting as either improvement or no worsening of features. There were minimal ophthalmic complications associated with treatment.
CONCLUSION
Endovascular treatment is safe and effective in the improvement of visual acuity, corkscrewing of conjunctival vessels, amount of proptosis, extraocular movement limitation, diplopia, and presence of audible bruit.

Orbital walls are one of the most common sites of midface fractures and account for ~40% of traumatic injuries in this region. These fractures are often associated with changes in the anatomy of the orbital cavity and frequently affect the orbital inferior wall, infraorbital groove and canal, and medial orbital wall, which leads to changes in its pattern and volume as well. Generally, the forces required for brake superior and lateral walls are greater than those required for thin medial and inferior walls. Disruption of any of these structures leads to the expansion of orbital volume that brings to the appearance of enophthalmos, diplopia, and impaired ocular mobility. The gold standard in the treatment of orbital wall fractures is surgical reconstruction, that includes fracture site exposure, freeing tissue prolapsed into the fracture site, and re-approximating the orbital wall support, usually with an orbital implant. It usually could be achieved by the usage of such as transconjunctival, subciliary, and coronal approaches and implementation of graft and reconstructive materials, including bones, cartilage, titanium, and resorbable mesh. Today, the gold standard in orbital floor reconstruction is the application of titanium mesh orbital plates. However, their implementation could be associated with a number of postoperative complications, such as mispositioning and orbital adherence syndrome. Orbital adherence syndrome is a poorly described and understood phenomenon and appears to occur after the use of large-pored titanium mesh for orbital reconstruction. It usually appears as limited eye movement that appears 1 to 2 weeks after reconstructive procedure. Prevention is possible through careful patient selection and the placement of a smooth interface medium in the initial surgery. The aim of the current study is to present the outcomes of orbital reconstruction done by both orbital mesh and customized smooth-surfaced titanium orbital implants.
