Abstract
Purpose: :
To investigate the correlation between different parameters of anterior chamber measurements using Pentacam® in Acute angle closure glaucoma(AACG) and Primary open angle glaucoma (POAG)
Methods: :
The central corneal thickness(CCT) and axial length(AL), anterior chamber depth(ACD), anterior chamber angle(ACA), anterior chamber volume(ACV) of acute angle closure glaucoma group (69 eyes of 67 patients), primary open angle glaucoma group (68 eyes of 63 patients), normal group (87 eyes of 79 volunteers) were measured and compared.
Results: :
In AACG, mean CCT, AL, ACA, ACD, ACV was 571.42±43.3µm, 22.37±1.48mm, 24.71±9.37°, 1.97±1.69mm, 93.4±46.84mm3 and in POAG was 546.37±37.5µm, 23.31±1.12mm, 35.47±11.41°, 2.87±0.82mm, 168.3±43.1mm3 , in normal group was 566.76±45.1µm, 23.37±1.89mm, 37.46±6.48°, 2.94±0.38mm, 171.9±40.31mm3 . the AL, ACA, ACD, ACV for AACG group was significantly smaller than for the other groups(p<0.05), and the CCT was significantly increased. Excellent correlation (R=0.841) was found between ACD and ACV in AACG group.
Conclusions: :
Using the Pentacam®, it was possible to examine different parameters of the anterior chamber within as short period and with good reliability. The evaluation of the ACD can help classify the potential risk for angle closure glaucoma.
