Abstract Objective: To explore the influence of relaxation of zonule in the pathogenesis of primary angle closure glaucoma. Methods: Seventeen subjects with primary acute angle-closure glaucoma (24 eyes), five subjects with primary chronic angle-closure glaucoma (10 eyes) and six subjects with angle-closure suspect (12 eyes) were enrolled in this study. The changes of anterior chamber depth (△ACD), lens thickness (△LT), lens position (△LP), trabecular-ciliary process angle (△TCPA) after myotic and mydriatict were measured by Lenstar and ultrasound biomicroscopy. The △LP and △TCPA could reflex the relaxation of zonule. Results: The differences of △ACD, △LT, △LP between the three groups were not significant (P>0.05). The differences of △ACD, △LT, △LP between the fellow eye and the acute eye in acute angle-closure glaucoma were not significant (P>0.05). The △TCPA of primary acute angle-closure glaucoma were larger than that of another two groups (P<0.001). But the differences of △TCPA between primary chronic angle-closure glaucoma and angle-closure suspect were not significant (P>0.05). The △TCPA of the acute eye in 6 o’clock was smaller than that of the fellow eye in acute angle-closure glaucoma (P=0.044). Conclusion: The weaken zonule maybe exist in primary acute angle-closure glaucoma in a certain extent.

Key words： glaucoma, angle-closure lens, crystalline zonule
