Neuromyelitis Optica Spectrum Disorder With Unilateral Retrobulbar Neuritis: A Case Report.
Cureus
December 2024
Neurology and Neuroscience, Medical University of Varna, Varna, BGR.
Neuromyelitis optica spectrum disorder (NMOSD) includes conditions with autoimmune genesis, which are manifested by attacks of optic neuritis (ON) and transverse myelitis (TM), and also express aquaporin 4 (NMO-IgG) or myelin oligo-endocytic glycoprotein (MOGAb) antibodies. In rare cases, the disease may also have a clinical presentation with only TM, without ON or with ON, without TM. These conditions are also included in the spectrum.

Acta Neurochir (Wien)
January 2025
Department of Neurosurgery, University Medicine Greifswald, Greifswald, Germany.
Purpose: Currently available grading and classification systems for hemifacial spasm either rely on subjective assessments or are excessively intricate. Here, we make use of facial recognition and facial tracking technologies towards accurately grouping patients according to severity and characteristics of the spasms.
Methods: A retrospective review of our prospectively maintained preoperative videos database for hemifacial spasm was done.
Removal of Subretinal Gas After Pneumatic Retinopexy Under Air Using External Manipulation.
Retin Cases Brief Rep
January 2025
The Retina Service of Wills Eye Hospital, Wills Eye Physicians-Mid Atlantic Retina, Thomas Jefferson University, Philadelphia, PA.
Purpose: To illustrate a technique for the removal of subretinal gas via pars plana vitrectomy (PPV) with air-fluid exchange and simultaneous manipulation with scleral depression.
Methods: PPV to remove subretinal gas causing persistent macula-off retinal detachment was performed in one eye, and the results were evaluated in this case report. Ports were carefully placed to avoid puncturing the retina, which was significantly displaced anteriorly past the ora serrata due to the buoyancy of the subretinal gas with the patient in a supine position.
Ciliary muscle traction during accommodation is able to induce optic nerve head deformation.
Eye (Lond)
January 2025
Key Laboratory for Biomechanics and Mechanobiology of Ministry of Education, Beijing Advanced Innovation Center for Biomedical Engineering, Beihang University, Beijing, China.
Objectives: To use finite element (FE) modeling and in vivo optical coherence tomography (OCT) imaging to explore the effect of ciliary muscle traction on optic nerve head (ONH) deformation during accommodation.
Methods: We developed a FE model to mimic the ciliary muscle traction during accommodation, and varied the stiffness of the sclera, choroid, Bruch's membrane (BM), prelaminar neural tissue and lamina cribrosa (LC) to assess their effects on accommodation-induced ONH strains. To validate the FE model, OCT images of the right eyes' ONHs from 20 subjects (25 ± 1.
Integrated course on ocular anatomy for ophthalmology clerkship.
BMC Med Educ
January 2025
State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-Sen University; Guangdong Provincial Key Laboratory of Ophthalmology and Visual Science, Guangzhou, China.
Background: Obtaining a full understanding of the anatomical structure of the eyeball and the contents within the eye plays a crucial role in learning eye diseases. However, it can be challenging for beginners to quickly learn, memorize, and apply this anatomical knowledge. To improve the teaching of ocular anatomy and help students overcome learning difficulties in ophthalmology clerkship, Zhongshan Ophthalmic Center developed an integrated ocular anatomy course comprising three main components: 'online preview,' 'lecture,' and 'wetlab dissection'.
