Purpose: To compare anterior segment parameters in angle?closure glaucoma (ACG), primary open angle glaucoma (POAG), and normal subjects (N) using a Schiempflug camera.
Methods: Central corneal thickness (CCT), lens thickness (LT), axial length (AL), anterior chamber angle (ACA), anterior chamber depth (ACD), and anterior chamber volume (ACV) were measured in ACG (93 eyes of 92 patients), POAG (90 eyes of 87 patients), and normal (91 eyes of 88 subjects) with Pentacamⓡ and A?scan. All of the results and measurements were then compared.
Results: Compared to normal and POAG patients, ACG patients presented with significantly different measurements of CCT, LT, AL, and ACA, ACD, and ACV (p<0.05). Further, correlations were high between three measurements (ACA, ACD, ACV) in ACG, and the best correlations were found in acute angle?closure glaucoma (P<0.05).
Conclusions: By using a Schiempflug camera it was possible to assess the correlation between anterior segment parameters (ACA, ACD, ACV) in glaucoma patients. The best correlations were found in acute angle?closure glaucoma, and thus anterior segment parameters can offer reciprocally complementary information.
