Purpose: To evaluate the superficial vascular density of the optic nerve head in different stages of pseudoexfoliation disease using optical coherence tomography angiography (OCTA).

Methods: In this cross-sectional study, 57 normal eyes, 41 eyes with pseudoexfoliation syndrome (PXS), 82 eyes with pseudoexfoliation glaucoma (PXG) and 27 non-glaucomatous fellow eyes of PXG (NL-PXG) that had OCTA were included. Circumpapillary RNFL (cpRNFL) thickness and circumpapillary capillary density (cpCD) were compared among the groups after adjusting for confounders using linear-mixed model.

Background: To evaluate changes in circumpapillary vessel density (cpVD) and retinal nerve fibre layer (cpRNFL) thickness after a successfully treated episode of acute primary angle closure (APAC) and to identify factors associated with glaucoma progression in these eyes.

Methods: Twenty-six patients successfully treated for a unilateral episode of APAC were included in this prospective study. Optical coherence tomography (OCT) cpRNFL thickness and OCT angiography (OCTA) cpVD were compared between 2 and 8 months after treatment.

Purpose: To evaluate the changes in circumpapillary vessel density (cpVD) and retinal nerve fiber layer (RNFL) thickness after an acute primary angle closure (APAC) episode.

Methods: Twenty-eight patients (28 pair of eyes) with unilateral APAC and 39 normal subjects (64 eyes) were included in this prospective, observational study. cpVD as measured by optical coherence tomography angiography and RNFL thickness as measured by spectral-domain optical coherence tomography were compared at 6 weeks after an APAC episode between affected, unaffected, and normal eyes.

Purpose: To compare outcomes of phacoemulsification combined with viscocanalostomy, endocyclophotocoagulation (ECP), or ab interno trabulectomy for intraocular pressure (IOP) control and safety in eyes with open-angle glaucoma and visually significant cataract.

Setting: Farabi Eye Hospital, Tehran, Iran.

Design: Retrospective case series.

Article Synopsis
  • Exfoliation syndrome (XFS) is a significant risk factor for secondary glaucoma, contributing to blindness globally, with known genetic variants in LOXL1 and CACNA1A linked to the condition.
  • Researchers conducted a study analyzing samples from multiple countries, discovering a rare protective allele at LOXL1 and refining its association, which had been previously inconsistent across different populations.
  • A genome-wide association study identified seven significant genetic loci related to XFS, providing new insights into its biological mechanisms and emphasizing the role of rare LOXL1 variants in the disease's development.

Purpose: To evaluate different mechanisms of primary angle closure (PAC) and to quantify anterior chamber (AC) parameters in different subtypes of angle closure disease using anterior segment optical coherence tomography (AS-OCT).

Methods: In this prospective study, 115 eyes of 115 patients with angle closure disease were included and categorized into three groups: 1) fellow eyes of acute angle closure (AAC; 40 eyes); 2) primary angle closure glaucoma (PACG; 39 eyes); and 3) primary angle closure suspect (PACS; 36 eyes). Complete ophthalmic examination including gonioscopy, A-scan biometry, and AS-OCT were performed.

Aim: To assess lens thickness measurements with anterior segment-optical coherence tomography (AS-OCT) in comparison with A-scan ultrasonography (A-scan US).

Methods: There were 218 adult subjects (218 eyes) aged 59.2±9.

Purpose: To compare the effect of phacoemulsification (Phaco) versus combined phacoemulsification and viscogonioplasty (Phaco-VGP) on long-term intraocular pressure (IOP) in primary angle-closure glaucoma (PACG).

Methods: In this prospective randomized clinical trial, 92 eyes of 82 patients with PACG and coexisting cataract were randomized to undergo Phaco alone (46 eyes) or Phaco-VGP (45 eyes) and completed the trial. Anterior segment optical coherence tomography was performed preoperatively and at 1 year after surgery.
