ABSTRACT
Objective To compare the difference of early optic nerve damage and visual field defect between primary open angle glaucoma(POAG)and primary angle-closure glaucoma(PACG).Design Prospective case series.Participants 30 eyes of 23 patients with early POAG and 30 eyes of 22 patients with early PACG were recruited.Methods Routine ophthalmologic exams,visual field (Humphrey Field Analysis 24-2),scanning laser polarimetry GDx ECC(Full Exam)were performed.Different types of RNFLD and GDx ECC parameters were compared between the two groups through X square-test and independent samples t-test,respectively.Both the intra-group globe visual indices and retinal sensitivity loss of each illumination target were compared with independent samples t-test. Main Outcome Measure GDx ECC parameters,types of RNFLD,visual indices and retinal sensitivity loss of each illumination target. Results Significant differences in all GDx ECC parameters of the two groups were found except Superior Average and Symmetry.In GDx ECC reports,diffuse RNFLD in POAG and PACG were 40% and 10%,respectively(P<0.05),while localized RNFLD were 53% and 63%,respectively.The differences of PSD and CPSD between groups were significant.More localized retinal sensitivity loss in the superiotemporal visual field in PACG were found.Conclusion The diffuse RNFL damage of early POAG is more than that of PACG. Differences between POAG and PACG in retinal sensitivity loss of the superiotemporal visual field are found,which are consistent with the RNFL damages.The pattern of RNFL damage and the visual field defects are different both functionally and structurally,which may give insight into the different etiologies of POAG and PACG.
