Purpose: To introduce a novel method to quantitively analyse in three dimensions traction forces in a vast area of the ocular posterior pole.
Methods: Retrospective analysis of 14 eyes who underwent peeling surgery for idiopathic, symptomatic and progressive epiretinal membrane. The technique measures the shift in position of vascular crossings after surgery from a fixed point, which is the retinal pigmented epithelium.
Purpose: The purpose of this study was to investigate the efficacy and safety of surgically induced macular detachment (MD) for the treatment of refractory full-thickness macular hole (FTMH).
Materials And Methods: Clinical data were age, gender, lens status, and best corrected visual acuity (BCVA). Preoperative tomographic parameters were: FTMH morphology (intraretinal cyst and elevated or flat edges) and FTMH diameter.
The radioiodine administration is a standard therapeutic approach to both benign thyroid diseases, such as hyperthyroidism, and carcinomas. The high administered (131)I activities are of radiation protection concern, due to relevant patient residual contamination. The aim of this work was to develop a new procedure based on external radiometric surveys and on a mathematical model in order to estimate the (131)I activity in patients undergoing hyperthyroidism radioiodine therapy.

Presentation Of Case: Below, we report two cases of small intestine metastatic melanoma with very different clinical presentation.
Discussion: Still now, primary versus metastatic origin is often unclear.
Objective: To compare the performances of four 64-slice CT devices, as regards radiation dose and image quality.
Methods: Effective dose was measured with thermoluminescent dosimeters in an Alderson Rando phantom (Alderson Research Laboratories, New York, NY). Quantitative image quality was evaluated in a Catphan 600 phantom (The Phantom Laboratory, New York, NY) using 3 parameters (modulation transfer function, contrast-to-noise ratio, and figure of merit).
