BACKGROUND The Impact of Cataracts on Mobility project has previously demonstrated that older drivers with cataract have an elevated risk of motor vehicle collision. OBJECTIVE To examine what types of visual impairment serve as a basis of the increased crash risk of older drivers with cataract. METHODS AND DESIGN A cross-sectional analysis was performed on 274 older drivers with cataract an...

Purpose To report a case of bilateral iridoschisis with cataracts and corneal decompensation in a patient who underwent cataract extraction and superficial iridectomy followed by Descemet membrane endothelial keratoplasty (DMEK). Observations A 58-year-old man with previously diagnosed iridoschisis, cataracts, and diabetes mellitus experienced progressive vision loss bilaterally due to cornea...

This paper proposes and evaluates an algorithm to automatically detect the cataracts from color images in adult human subjects. Currently, methods available for cataract detection are based on the use of either fundus camera or Digital Single-Lens Reflex (DSLR) camera; both are very expensive. The main motive behind this work is to develop an inexpensive, robust and convenient algorithm which i...

PURPOSE To investigate influences of 3% diquafosol sodium ophthalmic solution (DQS) on ocular surface after cataract surgery and effects on postoperative dry eye. DESIGN This study had two consecutive prospective study phases. The former was an observational study from before cataract surgery to 4 weeks after surgery and the latter was a randomized open-label study from 4 to 8 weeks after sur...

It is hardly debatable that poverty and poor health, however one measures either of these broad concepts, often exist together. Blindness, the most important manifestation of poor eye health, is no exception. World Health Organization estimates show higher rates of visual impairment in poorer countries, with few exceptions [1], and a recent large population-based survey in Pakistan found an ass...

We report on a series of 6 patients who experienced yellow vision after uncomplicated cataract surgery in their second eye. In the first eye, an aspheric blue-light filtering intraocular lens (IOL) was implanted, followed by the implantation of a 1-Piece aspheric IOL in the second eye. The time between the surgeries ranged from 12 months to 3 years. The patients experienced noticeable differenc...

Mechi zone is located in the eastern region of Nepal and has a population of 1.2 million. According to the Nepal Blindness Survey in 1981 the prevalence of blindness in this zone was 0.64%. The most important cause of blindness in Nepal was cataract, accounting for two thirds of NepalÕs blindness. The people of the eastern region of Nepal had to go either to the neighbouring zone or across the ...

PURPOSE Cataract is considered the main preventable cause of blindness and visual impairment mainly in poor countries. This study was done to evaluate if cataract is still an important cause of blindness in Central-West region of State of São Paulo, Brazil. METHODS A cross-sectional study was conducted with a systematically randomized sample of households in five cities located in Central-Wes...

Here we present the cases of three female children, of whom two were aged 6 years and one was aged 11 years. Two of the three children had bilateral uveitis and suspected cataract and Vogt-Koyanagi-Harada (VKH) disease. The third one had uveitis and suspected cataract in one eye and sympathetic ophthalmia (SO), and had undergone penetrating keratoplasty in the fellow eye following a trauma. Aft...
