Abstract Details
Purpose:
The aim of this study was to estimate mean values of anterior-chamber angle and corneal pachymetry in patients suspected or diagnosed with glaucoma, as well as to determine correlation between obtained variables
Setting:
Department of Ophthalmology, School of Medicine in Katowice, Medical University of Silesia in Katowice, Poland
Methods:
One thousand two hundred and ninety anterior-segment optical coherence tomography scans (Visante OCT, Carl Zeiss Meditec, Germany) of patients suspected or diagnosed with glaucoma, obtained in one month time, were collected and retrospectively analyzed in the aspect of patient age, gender, anterior-chamber angle and corneal pachymetry values. Statistical analysis of variables was performed with the use of Spearman and U Mann-Whitney tests. Statistical significance was accepted for p<0.05.
Results:
The study group consisted of 645 patients (mean age 55,5 ± 20,9 years, 427 women). Mean corneal pachymetry value was 547,1 ± 61,1µm, while mean anterior-chamber angle value was 26,2 ± 23,7 degrees. Angle closure was detected in 158 scans, with the main cause of angle closure being swelling of the lens. There was a statistically significant correlation between anterior-chamber angle and corneal pachymetry values (r=0,22) as well as anterior-chamber angle and patient age (r=-0,23). A substantial statistical difference between men and women was defined in the terms of anterior-chamber angle values (effect size r=0,86).
Conclusions:
Anterior-segment optical coherence tomography is an efficient imaging tool of angle closure detection. This fast and accurate estimation of anterior-chamber angle and central corneal pachymetry helps ophthalmologist in making important decisions regarding further treatment of the patient
