This study presents a high spatial resolution dosimetry system for quality assurance of I-125 eye plaques. The system is based on a silicon pixelated detector and is capable of deriving 3D dose distributions. A simple design was implemented, incorporating a movable eye plaque in a small water phantom above the silicon Medipix2 detector. It is designed for obtaining 2D dose distributions at different depths in water, for subsequent 3D dose mapping. The effect of backscattering in a medium placed behind the Medipix2 to simulate surrounding tissue has been studied in terms of dose distribution. Additionally, two modes of acquisition, event …

Eye drops are very commonly prescribed bur their potential for systemic absorption and serious toxicity may be forgotten. This paper examines patterns of prescription of eye drops in Scotland by general practitioners. A review of the serious systemic features and toxicity and their management, of commonly used eye drops is undertaken. Practical recommendations for the monitoring of such effects in clinical practice are made.
