When one makes up a clinical study, after posing a question to be answered by means of the data obtained by research, one can define the population to be studied. As it is not possible in general to evaluate all the population studied, one can select a sample. Sampling is when the analysis is performed based in a (representative) part of a population. In this stage, it is important to bear in mind that the only form of guarantee the […]

Objetivo: Comparar e registrar as alterações quantitativas e qualitavivas na tomografia de coerência óptica nos pacientes com uso prolongado de cloroquina. Métodos: Avaliaram-se cinco pacientes com diagnóstico de bull’s eye no exame de tomografia de coerência óptica macular com dois modelos de aparelhos: Stratus e Topcon 3D.

Iodotherapy represents the radioactive iodine therapy. The beta radiation emitted by radioactive iodine are particles that will be stored in the thyroid tissue destroying cancer cells that were left after surgery (thyroidectomy). It is important to emphasize a possible deleterious effect of therapy which affects the mucosa of the lacrimal system which results in a process of vascular inflammation and scarring producing disorders hypovascular, hypocellular and hypoxic.
