[A study of motion perception in primary open-angle glaucoma].

OBJECTIVE

To study the characteristics of the motion perception (MP) in primary open-angle glaucoma (POAG).

METHOD: Forty-one patients with POAG (67 eyes) and 56 (112 eyes) normal subjects were examined by the motion perception (MP) software in PC compatible computer.

RESULTS

The total abnormal rate of MP was 89.5% in POAG, and 81.6% in the early stage of POAG. By using the grade correlation analysis, there is positive correlation of the abnormal degree of MP with C/D, ocular tension, and corrected loss variance (CLV) of visualfield, negative correlation of the abnormal degree of MP with visual acuity and visualfield mean sensitivity (MS), and no correlation of the abnormal degree of MP with age and short-term fluctuation (SF) of visualfield in the POAG patients.

CONCLUSION

The examination of MP is a newly reliable and simple test for the diagnosis of the early POAG.
