Purpose: This study aimed to describe the ophthalmological features of Alström syndrome, a rare syndromic ciliopathy, and to delineate the genotype-associated disease spectrum.

Methods: Eight Taiwanese patients were recruited for this study. Pathogenic variants were identified using next-generation sequencing, and medical records were reviewed for systemic involvement.

Purpose: To investigate the risk factors for visual outcomes and recurrence of macular edema (ME) in branch retinal vein occlusion (BRVO) after intravitreal injection (IVI) of anti-vascular endothelial growth factor (anti-VEGF) agents.

Methods: Thirty eyes of 30 patients with recent-onset, treatment naive BRVO with ME receiving IVI aflibercept and ranibizumab in a tertiary care hospital were enrolled retrospectively. Treatment response was classified into "responsive group" and "recurrent/refractory group" by absence or presence of ME after consecutive monthly IVI anti-VEGF therapy.

As an alternative to assessments performed by human experts, artificial intelligence (AI) is currently being used for screening fundus images and monitoring diabetic retinopathy (DR). Although AI models can provide quasi-clinician diagnoses, they rarely offer new insights to assist clinicians in predicting disease prognosis and treatment response. Using longitudinal retinal imaging data, we developed and validated a predictive model for DR progression: AI-driven Diabetic Retinopathy Progression Prediction Algorithm (ADRPPA).

Background: To identify genotypes associated with neovascular age-related macular degeneration (nAMD) and investigate the associations between genotype variations and anti-vascular endothelial growth factor (VEGF) treatment response.

Methods: This observational, retrospective, case series study enrolled patients diagnosed with nAMD who received anti-VEGF treatment in National Taiwan University Hospital with at least one-year follow-up between 2012 and 2020. A genome-wide association study (GWAS) was conducted on enrolled patients and controls.

The diagnosis of inherited retinal degeneration (IRD) is challenging owing to its phenotypic and genotypic complexity. Clinical information is important before a genetic diagnosis is made. Metabolomics studies the entire picture of bioproducts, which are determined using genetic codes and biological reactions.

Article Synopsis
  • The Asia-Pacific region, housing about 60% of the world's population, lacks extensive knowledge about hereditary eye diseases, necessitating a regional collaboration to enhance precision medicine for affected patients.
  • The Asia-Pacific Inherited Eye Disease (APIED) network, consisting of 55 members from 35 centers across 12 countries, aims to address these gaps in understanding inherited retinal diseases (IRDs) by bringing together experts in the field.
  • The network's goals include improving genetic diagnosis of IRDs, standardizing phenotyping practices, and creating high-quality patient registries to support care and research in both regional and international contexts.*

Introduction: To evaluate the real-world efficacy of aflibercept using the treat-and-extend (TnE) regimen in treating neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV), and to analyze biomarkers using optical coherence tomography (OCT) to predict treatment outcomes.

Methods: Patients diagnosed with nAMD or PCV who received an intravitreal injection of aflibercept following the TnE regimen for ≥ 2 years were retrospectively reviewed. Data on best-corrected visual acuity (BCVA), number of injections, treatment interval, and OCT biomarkers, including central macular thickness, presence of subretinal fluid (SRF), and serous pigmented epithelial detachment, were collected at baseline and at 3, 6, 12, 18, and 24 months after the first injection.

A 48-year-old woman presented with persistent clouding vision in her lower field in the right eye for 5 months. A small retinal hemorrhage was initially reported. Her visual acuity was 20/30 in the right eye and 20/20 in the left, with normal color vision and pupil response.

Electroretinography (ERG) is an important and well-established examination for retinal and visual pathway diseases. This study reviewed the medical records of patients who received full-field ERG (ffERG) at a single medical center between 2012 and 2019, which was an 8-year experience in the clinical contribution of ERG. Based on the indication for scheduling ffERG and the final diagnosis, patients could be classified into six groups: 'retinal dystrophies', 'other retinal or macular diseases', 'optic neuropathies', 'visual complaints', 'systemic diseases', and 'others'.

Purpose: To investigate the presence and clinical relevance of hyperreflective foci (HRFs) in retinitis pigmentosa.

Methods: Seventy seven retinitis pigmentosa cases were retrospectively reviewed. The 10-mm wide cross-line macular scans in optical coherence tomography were acquired.

This study highlights the clinical features and treatment response of polypoidal choroidal vasculopathy (PCV) among three different branching vascular network (BVN) morphologies in optical coherence tomography angiography (OCTA), and further correlates the BVN features with those under fluorescent angiography (FA) and indocyanine green angiography (ICGA). In total, we reviewed 70 eyes with PCV followed up for > 12 months. OCTA, ICGA and FA images were obtained at baseline and post-treatments.

Leber's congenital amaurosis (LCA), one of the most severe inherited retinal dystrophies, is typically associated with extremely early onset of visual loss, nystagmus, and amaurotic pupils, and is responsible for 20% of childhood blindness. With advances in molecular diagnostic technology, the knowledge about the genetic background of LCA has expanded widely, while disease-causing variants have been identified in 38 genes. Different pathogenetic mechanisms have been found among these varieties of genetic mutations, all of which result in the dysfunction or absence of their encoded proteins participating in the visual cycle.

This retrospective study evaluated the association of hyperreflective foci (HRF) with treatment response in diabetic macular oedema (DME) after anti-vascular endothelial growth factor (VEGF) therapy. The medical records, including of ophthalmologic examinations and optical coherence tomography (OCT) images, of 106 patients with DME treated with either intravitreal ranibizumab or aflibercept were reviewed. The correlations between best-corrected visual acuity (BCVA) changes and HRF along with other OCT biomarkers were analysed.

Purpose: To investigate the characteristics of recurrent retinal detachment (RD) after diabetic vitrectomy (DV).

Methods: Consecutive cases underwent vitrectomy for recurrent RD after DV was collected and separated into the following four groups for analysis: rhegmatogenous RD (RRD), pure tractional RD (Proliferative Subgroup 1), combined RD with proliferative tissue within the equator (Proliferative Subgroup 2), and combined RD with both posterior and peripheral proliferations (Proliferative Subgroup 3).

Results: Of the 41 cases enrolled, retinal reattachment was achieved in 73.

This study analyze the morphological characteristics of branching vascular networks (BVN) in polypoidal choroidal vasculopathy (PCV) using optical coherence tomography angiography (OCTA), and correlate imaging characteristics with clinical presentations. We presented a retrospective observational case series for fifty cases of PCV confirmed by indocyanine green angiography. Macular OCTA were done by the AngioVue.

Purpose: To investigate the clinical manifestations and surgical results after vitrectomy for proliferative diabetic retinopathy (PDR) in young patients.

Methods: Clinical features of patients between 18 to 40 years old who received vitrectomy for PDR between January 2009 and January 2015 were retrospectively reviewed. Those older than 40 years who received vitrectomy for PDR during the same period were retrospectively enrolled and compared as the control group.
