    Although cataract is very common and its detection seems apparently easy especially in the mature cataract, its quantitative description to determine the critical value of diagnosis is too difficult. Non-invasive evaluation of the mechanical properties of eye is hampered by the absence of in-vivo methods for direct assessment of the axial length of eye, lens and cornea. In the present study...

The pathogenesis of cataract has been found to be influenced by a number of factors including oxidative stress. Catalase, glutathione peroxidase (GPX), and superoxide dismutase (SOD) are some of the antioxidant enzymes that protect the body from oxidative damage. The present study investigates the activities of erythrocyte catalase, GPX, and SOD with respect to senile cataract (non-diabetic cat...

A population-based survey of blindness was conducted in Vanuatu. Data were gathered on a sample of 3520 of the approximately 150,000 inhabitants of Vanuatu aged at least 6 years, in order to estimate the prevalence and causes of blindness among the whole population. An overall prevalence of blindness of 4.0 per 1000 was found, 85% of which was due to cataract, an avoidable cause of this disabil...

Ocular trauma is an important cause of unilateral visual impairment worldwide. According to Nepal blindness survey (Brillinat et al, 1985), it accounted for 2.4% of blindness, and in another community based study (Upadhyay M et al, 2001), the prevalence of ocular trauma was observed to be 0.7%. The Bhaktapur Eye Study confirms that “corneal trauma leading to ulceration” is the second most commo...

Introduction: Cataract is an opacified lens and senile cataract is a common disorder. It is desirable to reduce intraocular pressure (IOP) in order to minimize intra and post operative difficulties and complications. Many researches have studied the effects of muscle relaxants on IOP. Comparison effect of atracurium and pancuronium on IOP has been evaluated in one study with a small sample size...

Echium amoenum is an Iranian indigenous medicinal plant. In this research the effect of hydroalchoholic extract of this plant on sodium-selenite induced cataract formation was evaluated. Fifty five white rat pups were selected and divided into six groups. In first group (control 1) no elements injected. Second group (control 2) was received normal saline on 11-18 postpartum. Hydroalchoholic ext...
