Eligibility
Inclusion criteria
Inclusion criteria: Patient aged > 40 years fulfilling the criteria of PACS or PAC: primary angle closure suspect (PACS): characterized by narrow angles by gonioscopy (at least 180°of trabecular meshwork is invisible), but without IOP elevation, glaucomatous damage of the optic nerve, or visual field changes. Primary angle closure (PAC): having the same previous criteria but with elevated IOP and/or peripheral anterior synechia.
Exclusion criteria
Exclusion criteria: 1) Patients with history of previous ocular or refractive surgery, ocular injury, or laser procedure. 2) Patients with concurrent ocular pathology as cataract, diabetic retinopathy, dense corneal opacity, other posterior segment pathology or secondary glaucoma. 3) Patients with chronic angle closure with history of recurrent attacks of acute angle closure with extensive PAS that necessitates surgical intervention. 4) Patients with severe systemic disease and unable to tolerate LPI treatment such as tremors, heart and liver diseases. 5) Patients unable to cooperate for the examination, or unsuitable for gonioscopy like severe uveitis.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Measure and compare changes in the anterior chamber parameters in patients with primary angle closure suspect and primary angle closure before and after laser peripheral iridotomy using gonioscopic examination, AS-OCT, and corneal tomography. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1- Correlate between the anterior chamber parameters measured by AS-OCT, corneal tomography and gonioscopy. 2- Report changes in intraocular pressure one month and 3 months after LPI in patients with PACS and PAC. 3- Report any complications related to the intervention. | — |
