Refractive errors are ocular disorders that occur when the optical power of the eye produces an object image that is not focused on the retina. Although easily correctable in developed countries, the global burden of uncorrected refractive errors is enormous, with an estimated 145 million visually impaired and 8 million blind individuals.
Audrey Abella spoke with Dr Inez Wong, senior consultant ophthalmologist and director of paediatric ophthalmology and strabismus service at the Eagle Eye Centre in Singapore, on how GPs can manage refractive errors in the primary care setting.
Potential toxic optic neuropathy (TON) is common in workers with occupational exposure to unburnt tobacco, shows a recent study from India, which also finds advancing age and longer exposure duration as independent predictors of the condition.
New drug applications approved by US FDA as of 1 - 15 November 2017 which includes New Molecular Entities (NMEs) and new biologics. It does not include Tentative Approvals. Supplemental approvals may have occurred since the original approval date.
The presence of corneal arcus in Indian and Malay men appears to be associated with the risk of incident cardiovascular disease (CVD), independent of serum lipids and traditional CVD risk factors, reports a team of Singapore-based researchers.
The presence of vitreous haze, snow banking, and choroidal involvement is associated with an increased risk of antitubercular treatment failure in patients with tubercular (TB) uveitis, according to research by the COTS-1* Study Group.
Fluocinolone acetonide implant and systemic corticosteroid therapy both improve vision-related quality of life (VRQoL) in patients with noninfectious uveitis, according to a study. However, the implant group shows an immediate improvement as compared to gradual for the systemic group.
In diabetic macular oedema (DME), visual outcomes following intravitreal dexamethasone implant therapy may be predicted by early treatment response, according to a study. Specifically, eyes with optimal early responses demonstrate better outcomes compared with eyes having suboptimal early visual acuity gains.
It appears that allotopic gene therapy at low and medium doses is safe and does not damage the temporal retinal nerve fibre layer in patients with Leber hereditary optic neuropathy (LHON), paving the way for testing of the high dose, according to a new study.
The baseline inferior subfield retinal thickness may predict the frequency of treatment for diabetic macular oedema (DME) during the first year in eyes administered pro re nata (PRN) intravitreal ranibizumab (IVR) injections, a new study shows.
