background: increased oxygen free radical and reduced glutathione level in the eye lens are important risk factor for cataract formation. the antioxidative property and increasing cellular and extra cellular glutathione level have been reported by several herbal medicines including silymarin.  objective: in present interventional study silybum marianum l. seed extract (silymarin) was tested aga...

BACKGROUND Elective cataract surgery is the most commonly performed surgical procedure in developed countries. However, it is unclear whether cataract surgery on the second eye provides enough incremental benefit to be considered cost-effective. This study conducted a cost-effectiveness analysis of second-eye cataract surgery in the U.K. DESIGN A cost-effectiveness analysis. METHODS A decis...

purpose : a review of posterior capsule opacification (pco) after cataract surgery and some affecting factors methods : a cross-sectional study was designed to study cataract patients who underwent cataract surgery between 2003 and 2006 in farabi eye hospital, tehran, iran. random sampling was done. those with a history of uveitis, intraocular surgery, and eye trauma were excluded from the stud...

The aim of this study was to report a new cause of cataract, namely snake bite induced cataract in a dog. A 3-year-old male mongrel dog was referred to our clinic for the assessment of cataract in both eyes. The dog was bitten by a snake nearly 4 months ago. A 40 dioptre acrylic lens with 13 mm haptics was implanted into the lens capsule. In the left eye, posterior synechia was detected in the ...

A technique to improve an eye cataract early detection and quantitative evaluation of maturity using ultrasound was investigated. A broadband coherent signal, backscattered from an eye lens tissue, was digitized, recorded and processed. A new parameter – lens quality was proposed for the human eye cataract quantitative evaluation. Lens quality reflects two phenomena of ultrasound interaction wi...

introduction: the decline of visual function with increasing age is a significant concern in elderly. despite previous work on prevalence of specific ophthalmic pathologies, there has not been enough valid data about overall eye disorders in tehran yet, and it is poorly defined and not underpinned by strong evidence. the purpose of this study was to investigate the common eye disorders in the e...
