Análisis de la relación entre espesor corneal y cámara anterior mediante la Pentacam HR, en pacientes atendidos en la Clínica de Optometría de la Universidad Santo Tomás

Abstract

At present there are numerous teams that allow to determine the values of thickness, corneal curvature, amplitude, depth and volume of the anterior chamber such as the Pentacam HR; which is a team capable of creating a panoramic image in real time of the previous segment and a topographic-refractive study, yielding true and reliable results due to its high repeatability and reproducibility in the measurements (1-10).

The objective of this study was to analyze the relationship between corneal thickness with the anterior chamber using the Pentacam HR, in patients treated at the optometry clinic of the Santo Tomás University from February 2009 to December 2018. The study used was observational, descriptive, transversal court, where 604 examinations thrown by the Pentacam were taken from the years previously mentioned without any intervention to the patient and with the informed consent of the institution. The following parameters were analyzed: age, angle, depth, anterior chamber volume, corneal thickness and topographic shapes. The information was then tabulated and analyzed by means of statistical analysis.

The results were: a median age of 31 years, in the volume of 164 mm3, for the angle, depth and thickness was 556 µm. Age and corneal thickness in both women with a total population of 317 and men of 287, it was determined that the older the lower thickness.

This study allowed us to conclude that there is an inversely proportional relationship between age and corneal thickness, for the relationship between angle-volume and angle-depth, statistically significant data presented in both female and male groups was evidenced.

In the group of men, a greater relationship was demonstrated in terms of thickness-depth as well as thickness-angle than, as found in women, taking into account that the total sample is smaller in the male sex.

With respect to topographic forms, the highest prevalence was in women, being the regular form with 56.04% and the lowest frequency was the irregular topographic form with 51.24% in men.
