NCT ID: NCT06445634 Recruiting - Clinical trials for Glaucoma, Angle-Closure

Outcome of GATT Combined With Goniosynechiolysis in Glaucoma Patients With Secondary Synechial Angle Closure.

Start date: April 1, 2024
Phase: N/A
Study type: Interventional

To evaluate the intraocular pressure reduction effect of combined gonioscopy-assisted transluminal trabeculotomy (GATT) with goniosynechialysis in eyes with secondary synechial angle closure glaucoma.

NCT ID: NCT06333470 Not yet recruiting - Clinical trials for Primary Angle-Closure Glaucoma

Liwan Eye Study: the Fourth Follow-up

Start date: March 30, 2024
Phase:
Study type: Observational

Primary angle-closure glaucoma (PACG) is one of the major causes of blindness affecting more than 20 million patients worldwide. The goals of this observational cohort study are to investigate the 20-year incidence of PACG in Chinese population aged 50 years and to develop prediction models for the long-term risk of progression from primary angle-closure suspect (PACS) to PACG.

NCT ID: NCT06252246 Completed - Clinical trials for Primary Angle Closure Glaucoma

The Effect of Phacoemulsification on Intraocular Pressure in Primary Angle Closure Glaucoma (PACG) Patients At Phanat Nikhom Hospital, Chonburi Province

Start date: October 1, 2017
Phase:
Study type: Observational

BACKGROUND: Primary angle closure glaucoma (PACG) is one of a leading cause of blindness worldwide including Thailand. This problem impact to the overall health of people and health care system. Treatment guidelines of each stage is differenced. Therefore, factors that affect to treatment should be explored to plan for taking care patients in the future. OBJECTIVES: The study aimed to examine the effects of cataract surgery by phaco- emulsification on intraocular pressure and to determine the factors associated with intraocular pressure among primary angle closure glaucoma patients.

NCT ID: NCT06184620 Completed - Clinical trials for Primary Angle Closure Glaucoma

Correlation Between Angle Closure Glaucoma Data and Lens Zonule Status

Start date: December 1, 2020
Phase:
Study type: Observational

The goal of this observational study is to discuss the correlation between primary angle-closure glaucoma and the state of the suspended ligament of the lens and the pathogenesis of PACG by measuring the biological data of primary angle-closure glaucoma and observing its anatomical changes.

NCT ID: NCT06143943 Completed - Clinical trials for Glaucoma, Angle-Closure

Anterior Segment Anatomic Parameters for Risk Profiling of Primary Angle-closure Glaucoma

Start date: November 22, 2022
Phase:
Study type: Observational

The goal of this observational study is to examine the anterior segment anatomical parameters associated with the scleral spur and cornea for risk profiling of primary angle-closure glaucoma (PACG). The main question it aims to answer is: • Are there new anatomical parameters of the anterior segment of the eye that can be used early for risk profiling for PACG? Researchers will compare PACG and narrow angle groups to see if there are some anatomical parameters that can distinguish the two.

NCT ID: NCT06120621 Completed - Clinical trials for Narrow-Angle Glaucoma

Combined VCST With Phacoemulsification Versus Phacoemulsification in Primary Angle Closure Glaucoma

Start date: January 1, 2023
Phase: N/A
Study type: Interventional

As ab externo metal probe trabeculotomy cannot achieve 360-degree circumferential angle surgery, prolene suture can be used to achieve this without the need for an illuminated microcatheter. In order to combine the advantages of the use of viscoelastic and those of circumferential trabeculotomy, this technique (Visco-Circumferential-Suture- Trabeculotomy "VCST") was previously used successfully in PCG. (7) In the current study , the authors hypothesize that combination of VCST with phacoemulsification in primary angle closure glaucoma patients may have an added affect to phacoemulsification alone in cases with more extent of angle damage and that the injection of a viscoelastic into both ends of the unroofed SC before its cannulation by a polypropylene suture and subsequent circumferential trabeculotomy may facilitate circumferential cannulation of SC and hence the trabeculotomy and increase the success of the technique

NCT ID: NCT06000176 Completed - Clinical trials for Glaucoma,Primary Open-Angle ,Primary Angle Closure

Comparison of Optical Coherence Tomography Angiography Microvascular Changes in Primary Open Angle and Primary Angle Closure Glaucoma

Start date: April 5, 2022
Phase:
Study type: Observational

This work aims to study the peripapillary and macular microvascular changes in primary open angle and primary angle closure glaucoma using Optical Coherence Tomography Angiography (OCTA).
