NCT04495491 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 200

Last updated 2020-07-31

No results posted yet for this study

Summary

This study will compare the angle parameters of patients with PACS before and after LPI. The investigators will analyze the results of patients with different angle closure mechanisms before and after LPI, and participants hope to find the structural parameters for predicting the effect of LPI.

Conditions

Interventions

OTHER

pupillary block group

According to the configurations of angle closure, the pupillary block group is defined as the iris bombe.

OTHER

plateau iris group

According to the configurations of angle closure, the plateau iris group is defined as the thickness of the peripheral iris.

OTHER

mixing mechanism group

According to the configurations of angle closure, the mixing mechanism group is defined as the iris bombe plus thickening of the peripheral iris.
