Fungal corneal ulcers related to agriculture has been reported throughout the world, especially in tropical areas. Most of them were sporadic and had histories of ocular trauma or use of topical corticosteroids and topical antibiotics. Five onion harvesters had fungal corneal ulcers during the same harvest period in Southern Taiwan. The authors think that this is the first report of a group occ...

The advances in digital imaging and the improvement in interventional tools and devices like catheters and stents have expanded the use of interventional procedures. During the period 1998-2008, the total number of interventional procedures increased by 78% [1]. Interventional radiology [IR] and cardiology [IC] procedures deliver high radiation doses both to patients and medical personnel, whic...

  Background : Farmers and welders who work in open spaces and are exposed to direct sunlight are often exposed to sunlight radiation o n the neck and head . Thus, they may be afflicted with various types of skin cancer . The aim of the present study was to investigate the amount of UV exposure in welders working in Shahrud City , Iran .   Materials and Method s : This cross-sectio...

Farmers are at risk for work-related eye injuries, some of which can be very serious. This study describes the farm activities that were related to eye injury in a group of 36 Iowa farmers in the Agricultural Health Study who sustained 40 farmwork-related eye injuries requiring medical advice or treatment. Farm activities of grinding or cutting metal accounted for 11 (27.5%) of the eye injuries...

The dietary carotenoids provide photoprotection to photosynthetic organisms, the eye and the skin. The protection mechanisms involve both quenching of singlet oxygen and of damaging free radicals. The mechanisms for singlet oxygen quenching and protection against free radicals are quite different - indeed, under some conditions, quenching of free radicals can lead to a switch from a beneficial ...

The International Commission on Radiological Protection (ICRP) statement on tissue reactions, issued by the Commission in April 2011, reviewed epidemiological evidence and suggested that there are some tissue reactions where threshold doses are or may be lower than those previously considered. For the lens of the eye, the threshold is now considered to be 0.5 Gy. The absorbed dose threshold for...

PURPOSE To examine the expression of the major isoforms of cyclic guanosine monophosphate (cGMP)-dependent protein kinase (cGK) in mouse eye. METHODS Immunohistochemical localization of cGMP in mouse eye cryosections was performed using an anti-cGMP antibody, followed by visualization with indirect fluorescence microscopy. The presence of types Ialpha, Ibeta, and II cGK mRNAs in mouse eye ext...

PURPOSE To evaluate the role of the pineal gland in development of the chick eye in normal and constant light (CL) conditions. METHODS Chicks (Gallus gallus) were raised in either a 12-hour light-dark cycle (12L/12D) or in CL, with or without opaque, removable hoods that covered the top of the head for 12 hours each day. An additional group was raised with opaque eye occluders over the right ...

Sports have become increasingly popular and account for numerous eye injuries each year. The sports that most commonly cause eye injuries, in order of decreasing frequency, are basketball, water sports, baseball, and racquet sports. Sports are classified as low risk, high risk, and very high risk. Sports-related eye injuries are blunt, penetrating, and radiation injuries. The use of eye protect...

PURPOSE The Ocular Protection Index (OPI) 2.0 System was developed to evaluate ocular surface protection under a natural blink pattern and normal visual conditions. The OPI 2.0 System implements fully automated software algorithms which provide a real-time measurement of corneal exposure (breakup area) for each interblink interval during a 1-minute video. Utilizing this method, the mean breakup...
