Achados campimetricos em pacientes com adenoma hipofisário atendidos no CEMEC no período de março de 2018 a dezembro de 2019

Abstract

Introduction: Adenomas are benign tumors that have their origin in glandular tissue, and are able to develop in breast tissue, in the glands of the colon, and in pituitary tissue. The presence of adenomas implies hyper or hyposecretion of hormones related to the affected tissue. The research focuses on the visual changes that pituitary adenomas cause in patients. Objective: To analyze the campimetric findings by Humphrey and Pclab methods in patients with pituitary adenoma who had visual impairment due to pituitary mass effect on the optic chiasm. Methods: The medical records of 14 patients were analyzed, counting nineteen eyes, to characterize and quantify the patient´s campimetry according to the methods used. Total deviation (MD) and Pattern Standard Deviation (PSD) results were compared in the nasal and temporal hemifields. The results found in each hemifield were compared by Bioestat version 5.3 application. Results: The epidemiological profile of the analyzed patients demonstrated no prevalence of gender, and a mean age of approximately 38 years. In the Humphrey group 10 eyes were evaluated, with mean MD and PSD values of -13.388±7.9294 and 10.637±6.0229, of which only the PSD values revealed a statistically significant value. Regarding the 9 eyes analyzed by the Pclab method, we obtained a MD and PSD value of -2.5422±1.1554 and 3.8555±1.4918, of which only the PSD showed statistically significant results. Conclusion: Finally, when the Humphrey campimeter was used, a prevalence of temporal hemianopsia by the gray scale graph was shown, which was not evidenced in the patients who underwent the exam by the Pclab methodology, showing a predominance of temporal field loss. The PSD was more useful in clearly showing the loss of temporal visual field fibers. Thus, the current study has shown that the simple analysis of the grayscale graph fails to identify discrete chiasmatic defects in a considerable number of patients. In view of this, comparison of the mean deviations calculated for the hemicamples appear to be useful criteria for identifying such defects.
