Optical Coherence Tomography Quantitative Analysis of Changes in Anterior Chamber After Laser Peripheral Lridotomy

NCT02279472•Second Xiangya Hospital of Central South University

View on ClinicalTrials.gov

Summary

The purpose of this study is to analysis changes in anterior segment morphology after laser peripheral lrldotomy measured by optical coherence tomography, and to evaluate treatment effectiveness

Detailed Description

In the study ,primary angle closure(PAC) and primary angle closure glaucoma (PACG) will be recruited. Anterior segment optical coherence tomography images captured before and after laser peripheral iridotomy will be analysed to provide objective and reproducible quantification of anterior segment biometric parameters.The outcomes can provide useful information for clinical strategies in the treatment and management of pathology related to angle closure.
