Purpose: To evaluate and correlate the peaks and the fluctuation of intraocular pressure seen in the association of the ambulatory intraocular pressure curve with the water-drinking test versus the peaks and the fluctuation seen in the daily intraocular pressure curve.
Methods: The sample was as follows: 77 eyes belonging to 77 patients who were divided into three groups composed of 31 eyes belonging to 31 patients with primary open-angle glaucoma, 26 eyes belonging to 26 patients with normal tension glaucoma and 20 normal eyes belonging to 20 individuals.
Results: A significant correlation could be observed between the pressure peaks collected from the daily intraocular pressure curve and the pressure peaks seen in the ambulatory intraocular pressure curve, on the water-drinking test, as well as in the association of the ambulatory intraocular pressure curve with the water-drinking test.
Purpose: Since one of the most implicated factors in corneal endothelial cell loss after phacoemulsification is the ultrasound time, and that the "quick chop" technique utilizes less ultrasound time, the objective of this study was to compare and analyze the reduction of the central corneal endothelial cell density between the patients submitted to the "divide and conquer" and "quick chop" techniques.
Methods: Fifty-six patients with grade 3 senile cataract were prospectively selected and submitted to endocapsular phacoemulsification by the "divide and conquer" (28 patients, group 1) and "quick chop" (28 patients, group 2) techniques. The non-contact corneal central specular microscopy performed pre- and postoperatively at one month, 3 months and 6 months, and the ultrasound time used for each surgery, were verified.
