A 12-year-old castrated male cocker spaniel dog was presented with a 4-week history of left episcleral injection and pawing at the face. Clinical examination findings included left internal and external ophthalmoplegia, left dorsal strabismus, pain opening the mouth, and intermittent amaurosis. Imaging studies revealed a left orbital apex mass with adjacent sphenoid bone lysis and extension into the cranial cavity. A left exenteration was performed and histopathology confirmed an orbital soft tissue sarcoma. Key clinical message: This report describes an orbital tumor causing orbital apex syndrome. This condition should be differentiated from cavernous sinus syndrome as the latter does not course with optic neuropathy.

Objective: This systematic review aims to consolidate and analyze the existing evidence on Tolosa-Hunt syndrome (THS) in the pediatric population, focusing on clinical features, diagnostic challenges, treatment outcomes, and prognosis.
Background: Tolosa-Hunt syndrome is a rare headache disorder caused by idiopathic inflammation of the cavernous sinus, orbital apex, or orbit, resulting in neuro-ophthalmological manifestations. It is uniquely characterized by cranial nerve palsies and often responds well to steroids.

The authors present a case of an orbital apex venous malformation that presented with an intermittent oculomotor nerve palsy over a 15-year period. Radiologically, the lesion presented as a well-circumscribed orbital mass with T2 hyperintensity and enhancement that could only be demonstrated on 2-hour delayed phase imaging. The venous malformation was initially steroid-responsive but eventually became refractory to medical treatment alone.

Background: Transnasal endoscopic decompression of the optic nerve is increasingly gaining acceptance among ear, nose, and throat (ENT) surgeons, however neither strict indications for the procedure nor the precise extent of effective decompression have been firmly established to date. This study aimed to determine the distance between endoscopically visible, anatomical structures within the sphenoid sinus and the posterior (i.e.

This study aimed to examine the clinical features and assess the surgical outcomes of traumatic optic neuropathy in pediatric patients. A retrospective analysis was conducted on the clinical data of 15 cases (17 eyes) of traumatic optic neuropathy in pediatric patients aged 1 to 6 years between January 2015 and July 2024. Two of them presented with binocular trauma, resulting in a total of 17 affected eyes.

Background/objective: Orbital diseases often require precise measurements of eyeball volume, optic nerve sheath diameter (ONSD), and apex-to-eyeball distance (AED) for accurate diagnosis and treatment planning. This study aims to automate and optimize these measurements using advanced deep learning segmentation techniques on orbital Computed Tomography (CT) scans.
Methods: Orbital CT datasets from individuals of various age groups and genders were used, with annotated masks for the eyeball and optic nerve.
