Nationwide usage of ethambutol and incidence and screening practices of optic neuropathy

open access: yesFrontiers in Pharmacology
IntroductionEthambutol, a key anti-tuberculosis medication, is associated with optic neuropathy, which can lead to significant vision impairment. This population-based cohort study investigated the nationwide usage of ethambutol and the incidence and ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

OPA1 mutations induce mitochondrial DNA instability and optic atrophy 'plus' phenotypes [PDF]

open access: yesBrain, 2008
Mutations in OPA1, a dynamin-related GTPase involved in mitochondrial fusion, cristae organization and control of apoptosis, have been linked to non-syndromic optic neuropathy transmitted as an autosomal-dominant trait (DOA). We here report on eight patients from six independent families showing that mutations in the OPA1 gene can also be responsible ...

The contribution of brain reorganisation to recovery in patients with optic neuritis [PDF]

open access: yes, 2010
In this thesis, the mechanisms of damage and repair in clinically isolated optic neuritis (ON) were investigated in vivo, by combining magnetic resonance imaging (MRI), electrophysiology and optical coherence tomography (OCT).

Genetic testing confirmed osteopetrosis with initial presentation of nystagmus

open access: yesTaiwan Journal of Ophthalmology, 2023
Osteopetrosis (OS) is a rare heritable disorder characterized by osteoclast dysfunction and increased bone density on radiography. Optic nerve osseous compression is the most frequent ocular complication of OS, with nystagmus, strabismus, ptosis ...
