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
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.
95 studies on the registry are indexed under Glaucoma, Angle-Closure; 17 are open to participants now.
This study's planned enrollment of 40 is below the median of 57 across 59 interventional studies indexed under Glaucoma, Angle-Closure.

Exclusion Criteria:
Laser peripheral iridotomy (LPI) is widely regarded as the first-line intervention for either acute or chronic types of angle-closure glaucoma in early stage ,which relieves pupil block and thus flattening the iris contour and widening the drainage angle,performd by Nd.YAG LASER
Procedure: Laserex Tango Nd:YAG, Ellex-SuperQ Medical, Australia
All the patients will be achieved with pilocarpine 1% for pupil constriction, laser peripheral iridotomy(LPI) is performed using the ophthalmic neodymium: yttrium aluminium garnet laser (Laserex Tango Nd:YAG, Ellex-SuperQ Medical, Australia) and an VOLK iridotomy contact lens. After LPI, patients will be given topical prednisolone acetate 0.1% for 7 days.
Changes in anterior chamber after LPI at 1 month
Time frame: 1month
