Direct observation and measurement of circumlental space and its relation to anterior chamber angle characteristics in iridotomized phakic eyes with primary angle closure disease.

Primary angle closure disease (PACD) is a major cause of blindness worldwide. It has a high prevalence in East Asia, especially in China, which leads to a higher incidence of blindness than open-angle glaucoma. The aim of this study was to directly observe the circumlental space (CLS) in laser peripheral iridotomized eyes with PACD and to determine whether this structure plays a role in the pathogenesis of PACD.

Comparison of astigmatism correction and visual outcomes in mix-and-match implantations of trifocal intraocular lenses with femtosecond laser-assisted arcuate keratotomy and contralateral bifocal Toric intraocular lenses.

Introduction: Astigmatism reduces the postoperative visual performance after non-toric intraocular lenses (IOLs) implantation, and limits the use of refractive IOLs in cataract surgery. The purpose of this study was to compare the efficacy in astigmatism correction and the postoperative visual outcomes between the implantation of a trifocal IOL with femtosecond laser-assisted arcuate keratotomy (FSAK) in one eye and a bifocal toric IOL (TIOL) in the other, in patients with cataract and moderate astigmatism.

Methods: This prospective observational paired-eye study enrolled patients with cataract and corneal astigmatism (CA) between 0.

Unilateral pigmented paravenous retinochoroidal atrophy with acute angle-closure glaucoma: a case report.

Background: Pigmented paravenous retinochoroidal atrophy (PPRCA) is an uncommon fundus disease characterized by perivenous aggregations of pigment clumps and retinochoroidal atrophy distributed along the retinal veins. We report a Chinese female case of unilateral PPRCA with acute angle-closure glaucoma (AACG).

Case Presentation: A 50-year-old Chinese female presented with vision loss and elevated intraocular pressure (IOP) in the right eye and then underwent trabeculectomy.

Novel Discoveries of the Relationship Between the Vitreous Zonule and the Anterior Segment Characteristics in Eyes With Primary Angle-Closure Disease.

Purpose: To investigate the presence of the vitreous zonule (VZ) in different subtypes of primary angle-closure disease (PACD) and to explore the relationship between VZ and anterior chamber angle characteristics.

Methods: Patients with clinical diagnoses of acute primary angle-closure (PAC)/PAC glaucoma (APAC[G]) or chronic PAC/PAC glaucoma (CPAC[G]) and healthy subjects were enrolled. A total of 300 eyes of 180 subjects were included.
