Article Synopsis
  • Primary angle closure glaucoma (PACG) is a significant cause of vision loss in Asia, and current screening methods are complicated and require expert skills.
  • This study aims to create an AI algorithm that predicts anterior chamber depth (ACD) from smartphone photos taken with a portable slit-lamp microscope, making it a faster screening option for PACG.
  • The developed model shows high accuracy in predicting ACD and effectively estimating the risk of angle closure, laying the foundation for future advancements in PACG screening methods.

Background: The aim of this study, which included a baseline cross-sectional study and a 3-year follow-up prospective study, was to investigate the association between glaucomatous visual field damage and driving cessation in subjects with primary open-angle glaucoma (POAG).

Methods: A total of 211 POAG subjects divided into 3 groups according to POAG severity (mild, moderate, or severe) in the better eye were enrolled along with 148 control subjects; subjects were asked about changes in their driving status. In the 3-year follow-up study, 185 of the POAG subjects and 80 of the controls annually reported their driving status.

Background: To investigate the relationship between clinical risk factors, including visual field (VF) defects and visual acuity, and a fear of falling, among patients with primary open-angle glaucoma (POAG).

Methods: All participants answered the following question at a baseline ophthalmic examination: Are you afraid of falling? The same question was then answered every 12 months for 3 years. A binocular integrated visual field was calculated by merging a patient's monocular Humphrey field analyzer VFs, using the 'best sensitivity' method.

Purpose: We predict the likelihood of a future motor vehicle collision (MVC) from visual function data, attitudes to driving, and past MVC history using the penalized support vector machine (pSVM) in subjects with primary open-angle glaucoma (POAG).

Methods: Patients with POAG were screened prospectively for eligibility and 185 were analyzed in this study. Self-reported MVCs of all participants were recorded for 3 years from the baseline using a survey questionnaire every 12 months.

Purpose: To identify the incidence rate of motor vehicle collisions (MVCs) in patients with no ocular pathology other than primary open-angle glaucoma (POAG) and determine the putative risk factors for MVCs in this group of patients.

Methods: We designed a prospective cohort study across three centers utilizing a consecutive sampling method to identify all patients with POAG between the ages of 40 and 80 years old. Patients with glaucoma were consecutively screened for eligibility.

Purpose: We evaluated the association between functional visual acuity (FVA) and visual fields in glaucoma patients.

Patients And Methods: Forty-seven patients with glaucoma were enrolled (28 men, 19 women; mean age: 65.2±7.

The aim of the present study was to evaluate sleep and mood disorders and related ocular parameters in glaucoma patients. We focused on visual fields and the retinal nerve fibre layer, because decreased circadian photoreception by damaged intrinsically photosensitive retinal ganglion cells is suspected in glaucoma. A cross-sectional study was performed on 140 subjects: 69 with glaucoma and 71 normal controls.

Purpose: To confirm that subjects with primary open-angle glaucoma (POAG) who avoid driving in high-risk situations are less likely to be involved in motor vehicle collisions (MVCs) than those who do not.

Methods: This study evaluated 252 consecutive Japanese aged between 40 and 85 years with POAG. All participants were requested to answer a questionnaire on their driving habits, including self-restriction in driving at night, in rain, in fog, on freeways, and lane changing, and history of MVCs.

Purpose: To design a mathematical model that can predict the relationship between the ganglion cell complex (GCC) thickness and visual field sensitivity (VFS) in glaucoma patients.

Design: Retrospective cross-sectional case series.

Method: Within 3 months from VFS measurements by the Humphrey field analyzer 10-2 program, 83 eyes underwent macular GCC thickness measurements by spectral-domain optical coherence tomography (SD-OCT).

Purpose: To determine if glaucomatous visual field defect severity is associated with fear of falling.

Methods: This is a cross-sectional study. A total of 387 consecutive subjects with POAG were enrolled in this study along with 293-ocular disease-free control subjects, who were screened at the same institutions.

Aim: To evaluate the association between the magnitude of relative afferent pupillary defect (RAPD) and the laterality of visual fields in glaucoma patients using pupillography.

Methods: Evaluations were made with an RAPDx (Konan Medical USA, Irvine, California, USA), which is designed to analyse pupil responses to multiple colour stimuli (white, red, green, blue, and yellow) at multiple controlled stimulus intensities. Humphrey automated perimetry (SITA standard 30-2) was performed to determine mean deviations (MDs), which were used to evaluate associations between MD differences (better eye MD-worse eye MD) and RAPDx amplitude and latency measurements in pupil response to multiple colour stimuli.

Purpose: To investigate the long-term effects of postoperative flat anterior chamber (FAC) development on outcomes following trabeculectomy with mitomycin C.

Methods: This was a retrospective cohort study. Data on 383 consecutive patients (383 eyes) who underwent trabeculectomy at our institution between 1999 and 2009 were followed up.

Purpose: To investigate the incidence, risk factors, time course and prognosis of ocular surface complications after trabeculectomy.

Procedures: This is a retrospective, case-control study. Data on 399 consecutive patients who underwent trabeculectomy between 1999 and 2009 were evaluated.

Purpose: To investigate the incidence of intraocular pressure (IOP) elevation after Descemet's stripping endothelial keratoplasty (DSEK) and associated clinical findings.

Methods: Forty-eight eyes of 46 patients who underwent DSEK were studied in this single-center retrospective study. IOP elevation was defined as the presence of an increase in IOP above 21 mmHg lasting at least two months, the need to introduce topical/oral antiglaucoma medications for at least two months, and the need for surgical therapy for uncontrolled IOP.

Purpose: Falls are among the most serious public health concerns for the elderly. Information conveyed via the visual sense is relevant to postural balance and movement, and proper visual function is essential to avoid falls. Here we investigated the prevalence of injurious falls among patients with primary open-angle glaucoma (POAG) who were more than 45 years old, compared with comparably aged healthy subjects.

Purpose: To investigate the influence of deficiency in superoxide dismutase (SOD) 1, a major antioxidative enzyme, on retinal ganglion cells (RGCs).

Methods: In the SOD1 total knockout (SOD1-deficient) mice, the level of superoxide anion was measured using dihydroethidium. The number of RGCs was counted in both the retinal sections and the flat-mount retinas after retrograde labeling.
