INFLUENCE OF VISUAL FIELD TESTING ON INTRAOCULAR PRESSURE IN PATIENTS WITH GLAUCOMA SUSPECTS ATTENDING TERTIARY CARE CENTER IN KATHMANDU

Abstract

Background: The evaluation of glaucoma includes measurement of the intraocular pressure and Visual field. Both procedures frequently take place on the same appointment. A rise in intraocular pressure brought on by either internal or external sources could change the recommended course of treatment. The management of patients, therefore, benefits from understanding intraocular pressure changes and their implications. The goal of this study was to determine how visual field testing affected intraocular pressure in glaucoma suspects and glaucoma patients.

Methods: The study’s cross-sectional design was carried out from October 15, 2020, to September 15, 2021, in a tertiary eye care facility. Intraocular pressure was measured before and after the visual field test. Data entry, as well as data analysis, was done on IBM SPSS 20. For comparisons of the intraocular pressure, the Wilcoxon signed-ranks test was used. A P ≤0.05 was considered statistically significant.

Results: The Analysis of the data set showed no statistical significance difference between the intraocular pressures obtained before and after the test in each of the eyes and regarding the test duration

Conclusions: Short-duration visual field testing did not significantly influence intraocular pressure, according to the study. This finding suggests that when clinically evaluating both the glaucoma patients and suspects, the visual field test may be done concurrently with the intraocular pressure measurement.
