Objective: Oncocytomas of the lacrimal gland are rare tumors. We report the eighth case in the literature.
Design: Interventional case report and literature review.
Intervention: Complete ophthalmologic and systemic examination followed by excisional biopsy and histopathologic examination.
Results: A 40-year-old Hispanic woman was evaluated for a right-sided upper eyelid edema and pain on ocular motility. A month earlier an outside ophthalmologist had performed a conjunctival biopsy that disclosed chronic inflammation. Computed tomography and magnetic resonance imaging of brain and orbit demonstrated a right intraorbital extraconal soft tissue density mass that involved the lacrimal gland, upper eyelid and encroached both the superior oblique and superior rectus muscles. Histopathology showed a benign oncocytoma that replaced most of the lacrimal gland.
Conclusion: Although rare, oncocytomas should be included in the differential diagnosis of any lacrimal gland tumors.

Department of Anatomy Faculty of Medicine, Istanbul Medipol University, Istanbul, Türkiye.
Purpose: Given the potential role of nasolacrimal duct (NLD) morphometry in the aetiology of primary acquired obstructions, it is imperative that clinicians have access to detailed anatomical information. The aim of this study was to determine normative data on nasolacrimal duct morphometry in the Turkish population sample and to provide guidelines for clinicians.
Methods: The study included retrospectively computed tomography images of a healthy Turkish population sample of 151 individuals, 79 of whom were female and 72 of whom were male.

Purpose: Congenital epiphora can be related to anomalies of the nasolacrimal duct. This study aimed to assess the distal end of the nasolacrimal duct and the outcomes of endoscopic treatment in children older than 12 months with congenital epiphora.
Methods: This retrospective analysis describes the clinical characteristics, management, and outcomes of symptomatic congenital lacrimal obstruction in 32 lacrimal systems of 23 children.

Department of Ultrasonography, The Second Affiliated Hospital of Chongqing Medical University, Chongqing, China.
Purpose: This study evaluates the effectiveness of lacrimal gland ultrasonography (LGUS) and shear wave elastography (SWE) in distinguishing primary Sjögren's syndrome (PSS) patients from healthy controls and examines their role in assessing disease activity and prognosis.
Methods: A total of 35 PSS patients and 23 age- and gender-matched healthy controls were included. LGUS was used to grade lacrimal gland structure, while SWE assessed gland elasticity.

The human lacrimal gland (LG), located above the outer orbital region within the frontal bone socket, is essential in maintaining eye surface health and lubrication. It is firmly anchored to the orbital periosteum by the connective tissue, and it is vital for protecting and lubricating the eye by secreting lacrimal fluid. Disruption in the production, composition, or secretion of lacrimal fluid can lead to dry eye syndrome, a condition characterized by ocular discomfort and potential eye surface damage.

Pain management requires the identification of certain indicators to recognize pain. Various tools have been suggested to achieve an objective evaluation, including infrared thermography (IRT). The objective of this study was to assess the facial thermal nociceptive response produced by the use of cannabidiol (CBD) alone and in combination with meloxicam in female dogs undergoing elective ovariohysterectomy anesthetized with isoflurane.
