Therapeutic Antithrombotic Agent Use and Bleeding Risk in Retrobulbar Anesthesia for Outpatient Ophthalmic Surgery.
Cureus
December 2024
Ophthalmology, Hartford Hospital, Hartford, USA.
Background and objective Retrobulbar block is commonly used for providing effective anesthesia and akinesia for ophthalmic surgery. It can, however, lead to sight-threatening retrobulbar hemorrhage in very rare cases. The aim of this study was to evaluate retrobulbar block quality, to determine the prevalence of retrobulbar hemorrhage associated with these blocks, and to assess whether the use of antithrombotic agents in patients undergoing retrobulbar block for ophthalmic surgery was associated with retrobulbar hemorrhage.

Mucormycosis is an aggressive, lethal fungal infection affecting the nasal and paranasal territory in immunocompromised patients. Orbital involvement is not uncommon and may require orbital exenteration. The management of orbital involvement in invasive fungal sinusitis is challenging, ranging from conservative retrobulbar amphotericin B injection in the early stages to orbital exenteration in late stages.

Herpes zoster Ophthalmicus (HZO) affecting the ophthalmic division (V1) of the trigeminal nerve. HZO may cause extraocular muscle palsies, with the third nerve being the most commonly affected and the fourth nerve the least. The combined involvement of the optic nerve and isolated paralysis of the eye muscle is very rare, with only limited case reports documenting this complication of ocular herpes zoster.

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.

Department of Internal Medicine, Ochiai Hospital, Maniwa, JPN.
Infective endocarditis is a life-threatening disease and the early diagnosis is crucial for a better outcome. We report an old adult who developed infective endocarditis in association with new-onset maxillary sinusitis as well as proptosis, which was caused by an orbital mass lesion in the background of pre-existing orbital vascular malformation. A 74-year-old woman was found incidentally to have right orbital vascular (venous) malformation by head magnetic resonance imaging when she was hospitalized for left dorsal pontine infarction.
