Filter by: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.
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.
Purpose: To investigate agreement between 2 swept source OCT biometers, IOL M.aster700 and Anterion, in various ocular biometry and intraocular lens (IOL) calculations of primary angle-closure disease (PACD). Methods: This was a prospective study conducted in a tertiary eye care centre involving biometric measurements obtained with 2 devices in phakic eye with diagnosis of PACD. Mean difference and intraclass correlation coefficient (ICC) with confidence limits were assessed, and calculations of estimated residual refraction of the IOL were analysed using Barrett's formula.
This prospective study included patients with primary angle-closure (PAC or primary angle-closure glaucoma (PACG) and visually significant cataract. Phacoemulsification with multifocal intraocular lens (MIOL) or monofocal IOL (mIOL) (patient preference) was performed. Collected data included best-corrected distant visual acuity (BCVA), intraocular pressure (IOP), anterior chamber depth (ACD), and contrast sensitivity (CS) measured at spatial frequency 1.5, 3.0, 6.0, 12.0, and 18.0 cycles per degree (CPD) preoperatively, and at 2-6 months postoperatively. Preoperative and postoperative parameters were compared to evaluate the effect of MIOL on CS in eyes with PAC or PACG.
This study is a prospective evaluation of the Hydrus Microstent for the treatment of Primary Angle Closure (PAC) and Primary Angle Closure Glaucoma (PACG) with adjunctive cataract. A total of 20 subjects will be successfully treated with one Hydrus device after completion of cataract extraction with phacoemulsification followed by IOL replacement (HMS cohort), and 10 eyes will be treated with phacoemulsification cataract extraction and IOL replacement only (PCS group). Since cataract surgery is standard of care for this condition, eligible fellow eyes from the HMS cohort may be enrolled into the PCS group. To avoid selection bias in this non-randomized study, the first 20 consecutive qualifying subjects will be treated with Hydrus and the next 10 consecutive qualifying eyes will be treated with cataract surgery only.
Assessing the safety and efficacy of a micro-bypass stent in combination with cataract surgery in subjects with primary angle closure. Subjects are randomized into two arms: phacoemulsification cataract surgery alone versus phacoemulsification cataract surgery combined with the micro-bypass stent implantation. Post surgery intraocular eye pressure will be recorded to assess the efficacy of both arms.
