Cataract is the presence of opacity in the crystalline lens of the eye. It causes painless, progressive blurring of vision.
It is the leading cause of blindness worldwide and the most prevalent ocular disease.
The initiating events that lead to loss of transparency of both the cortical and nuclear lens tissue is the oxidation of the membrane lipids, structural or enzymatic proteins or DNA by peroxidases or free radicals induced by UV light.
Children with uveitis commonly develop cataract, and the development of the eye disease is strongly associated with the extent of inflammation recurrences and ocular complications, according to a cohort study.
Paediatric patients with uveitis commonly develop cataract, and the risk of cataract development increases with the extent of inflammation recurrences and ocular complications, according to a cohort study.
More than two-thirds of adults with visually significant cataract are unaware of their condition, and half of those undiagnosed have bilateral visual impairment, results from the Singapore population-based SEED* study show.
The use of intraoperative wavefront aberrometry (IWA) in calculating intraocular lens (IOL) power during routine cataract surgery is not reliable due to its high rate of measurement failures and the large variations of the readings, a study has shown.
A new population-based study has reported that at least 66 percent of Singaporean adults have undiagnosed visually significant cataracts, and that a further half of this experience considerably reduced qualities of life as a result of bilateral visual impairment.
Based on the existing literature, there may be an association between the use of glucocorticoids and the subsequent development of cataract, a meta-analysis reports. However, because there isn’t enough evidence and adequate studies, this risk cannot be accurately determined for those with rheumatoid arthritis.
Persistent foetal vasculature (PFV) and its variants appear to be the most common ocular manifestation of unilateral congenital cataract in infants, but the prevalence of the significant cataract-related systemic disease is rather low, according to 5-year data from the Infant Aphakia Treatment Study (IATS).
On 8 August, the first town hall held by the Ministry of Health (MOH) with members of the pharmacy profession took place in Putrajaya. Over 500 pharmacists from across the country and from different areas of practice—community and hospital, public and private, academy and industry—converged to fill the auditorium for the chance to engage in direct dialogue with MOH.
Early administration of recombinant human B-type natriuretic peptide (rhBNP) can lower the incidence of reperfusion injury for patients with ST-elevation myocardial infarction (STEMI) who are receiving percutaneous coronary intervention (PCI) treatment, according to a China study.
Intraoperative methylprednisolone does not appear to significantly prevent the incidence of death, cardiac arrest and other injuries in neonates undergoing cardiac surgery with cardiopulmonary bypass, according to a recent study.
