Background: Oxidative stress is a condition where the balance between production and elimination of reactive oxygen species (ROS) disturbed. ROS can cause damage to various biomolecules, including DNA. DNA impair function survival cells, may contribute development cataracts. Several experimental studies have shown that oxidative involved in cataract formation by inducing lens cells.. are create...

PURPOSE Changes in lens may reflect the status of systemic health of human beings but the supporting evidences are not well summarized yet. We aimed to determine the relationship of age-related cataract, cataract surgery and long-term mortality by pooling the results of published population-based studies. METHODS We searched PubMed and Embase from their inception till March, 2014 for populati...

Age-related cataracts are one of the most prevalent causes visual impairment around world. Understanding mechanisms cataract development and progression is essential to enable early clinical diagnosis treatment preserve acuity. Reductive chemicals potential medicines effective on treatment. In this work, we investigated cataract-induced oxidative damage in crystalline lens a kind reductant, ?-l...

PURPOSE To investigate the ocular features of children with congenital cataract in a tertiary referral eye center in East China. METHODS We retrospectively reviewed the clinical data of congenital cataract children who underwent cataract surgery between April 2009 and April 2014 at the Eye and ENT Hospital of Fudan University and identified factors associated with the axial length (AXL) and c...

BACKGROUND The purpose of this study was to evaluate the effects of cataracts on the flicker electroretinograms (ERGs) recorded with the RETeval™ system under mydriatic-free conditions. METHODS This was a retrospective study of 82 eyes of 60 patients with cataracts and 52 eyes of 38 patients who were pseudophakic. Flicker ERGs were recorded with the RETeval™ system (LKC Technologies, Gaithers...

cataract is clouding of the eye lens that reduces the amount of incoming light and results in deteriorating vision. blindness is thought to reach 75 million by 2020. of these, unoperated cataract may be expected to account for at least 35 million. thus, the burden of cataract is increasing remorselessly. embelica officinalis is reported to have a very good antioxidant property and thus we hypot...
