Abstract Strontium 90 (Sr-90) has been commonly used in the radiation treatment of pterygia eye. A radioactive plaque is placed an applicator onto surface eyeball for a specific length time to achieve desired dose. Dose usually calculated using source activity and decay, as well distance from it However, this assumes flat eye surface. This investigation 3D printing produce anthropomorphic phant...

CASE REPORT A 59 year-old male with choroidal melanoma in the left eye who underwent plaque brachytherapy (iodine 125). One week after surgery, massive exudation with retinal detachment and lipid exudation was observed. Evolution was assessed with funduscopy and ultrasound every month. Nine months after surgery transpupillary thermotherapy (TTT) was performed over the fluid-free irradiated resi...

A case of senile scleral plaques is reported in which expulsion of a calcified plaque anterior to the insertion of the medial horizontal rectus muscle gave rise to senile scleromalacia. Histopathological examination revealed a second calcified plaque at the site of the contralateral senile scleral plaque in this eye. This case indicates that senile scleromalacia is a scleral disease sui generis...

PURPOSE To recalculate the radiation doses delivered to structures of interest within the eye, i.e., the lens, tumor apex, 5-mm point, optic disk, and macula for patients treated with eye plaque radiotherapy on the Collaborative Ocular Melanoma Study (COMS) Medium Tumor Trial, using updated dosimetric data. METHODS AND MATERIALS Using the Plaque Simulator planning system, doses were recalcula...

OBJECTIVE To evaluate the use of 3-dimensional (3D) ultrasonography for the localization of episcleral eye plaques during the treatment of choroidal melanomas. METHODS A series of 13 patients with choroidal melanoma were treated with radioactive palladium 103 seeds affixed into gold eye plaques. During surgery, 3D ultrasonography was performed with a commercially available system to evaluate ...

Vernal Shield ulcer is a rare sight threatening corneal manifestation of vernal keratoconjunctivitis. This study is designed to report management of a refractory shield ulcer that did not respond to variety of medications but healed in 1 week after surgical debridement of ulcer base. A 12-year old Omani boy with H/O vernal conjunctivitis since 5 years on ketotifen eye drops presented with a shi...

寺 田喜久雄,西 村 かず よ,木 羽敏泰:金 沢大学理学部化学教室,金 沢市丸 の内1-1〒920 A simple and effective method for determining 106Ru in sea water is presented. After the sea water is heated with oxidants (potassium peroxodisulfate and potassium periodate) in potassium hy droxide solution, ruthenium tetraoxide is extracted into carbon tetrachloride from the aqueous solution adjusted to pH 4-6, and then back-extracted with a ...

E. lye movements may be divided grossly into "tonic" and "phasic" movements. Are both of these principal types produced by the same motor nerves and muscle fibers, or are separate systems present that are functionally suited to each of the types of movements? Morphological and physiological studies demonstrate that at least two and possibly three neuromuscular systems are present in eye muscles...
