Background And Objective: Liver health has been reported to be associated with retinal pathology in various ways. These include deposition of retino-toxins, neovascular drive, and disruption of the blood-retina barrier. Extrahepatic synthesis of implicated molecules and hemodynamic changes in liver dysfunction are also considered.

Background: Automated identification of spectral domain optical coherence tomography (SD-OCT) features can improve retina clinic workflow efficiency as they are able to detect pathologic findings. The purpose of this study was to test a deep learning (DL)-based algorithm for the identification of Idiopathic Full Thickness Macular Hole (IFTMH) features and stages of severity in SD-OCT B-scans.

Methods: In this cross-sectional study, subjects solely diagnosed with either IFTMH or Posterior Vitreous Detachment (PVD) were identified excluding secondary causes of macular holes, any concurrent maculopathies, or incomplete records.

Background And Objective: Macular thickness fluctuations (MTF) over time may be more predictive of visual outcomes than absolute macular thickness in patients with diabetic macular edema (DME) treated with anti-vascular endothelial growth factor (anti-VEGF). It is unclear whether this association exists in DME patients treated with intravitreal steroids or whether steroids confer reduced MTF versus anti-VEGF treatments.

Patients And Methods: MTF was compared before and after initiation of steroids in DME patients treated with intravitreal steroids.

Objective: This study investigates the association between preoperative intraretinal fluid (IRF) area and preoperative and postoperative best-corrected visual acuity (BCVA) in surgically repaired idiopathic macular holes (MH). This study further evaluates other prognostic indices related to MH repair that may assist clinicians' understanding of MH operative management.

Design: Retrospective cohort study conducted at a single institution.

Background And Objectives: To pool available data on the change in best-corrected visual acuity (BCVA), central retinal thickness (CRT), and number of injections as reported by treat and extend (T&E) and pro re nata (PRN) regimens for retinal vein occlusion (RVO).

Materials And Methods: After PubMed was queried, separate random effect models were fitted to the data extracted and the Wald test was used to compare the estimates of the two independent meta-analyses.

Results: Fourteen T&E and 29 PRN studies were included in two independent meta-analyses.

Article Synopsis
  • The study aimed to evaluate the COVID-19 positivity rates during presurgical screenings for ophthalmic patients and analyze surgical outcomes, along with the overall costs involved.
  • Out of 3,585 patients screened, only 13 asymptomatic cases (0.36%) tested positive, and 10 of these were newly identified infections, leading to a few surgery delays averaging 17 days.
  • The total cost of screening was approximately $800,000, suggesting the need for more focused future studies on targeted presurgical testing rather than blanket testing.

Background: Intravitreal injections of anti-vascular endothelial growth factor (anti-VEGF) are first-line therapy for macular oedema in retinal vein occlusion (RVO). Appropriate management for RVO with good visual acuity at diagnosis has not been evaluated. The purpose of this study is to analyse the visual and anatomic outcomes from anti-VEGF treatment among RVO patients with good vision at baseline.

Objective: Having a better understanding of how long diabetic macular edema (DME) takes to resolve in patients with diabetic retinopathy (DR) after treatment with ranibizumab, and the factors affecting this outcome, would be of benefit to physicians and patients alike. The objective of this analysis was to evaluate the time to first DME resolution and the impact of baseline DR severity on this outcome in patients treated with ranibizumab in phase III clinical trials.

Design: Meta-analysis of data from the phase III trials, RIDE (NCT00473382) and RISE (NCT00473330), and DR Clinical Research Network protocols I (NCT00444600), S (NCT01489189), and T (NCT01627249).

Objective: To examine the time to onset of disease in the fellow eye of patients with unilateral DMO in routine clinical practice and to identify risk factors for development of bilateral DMO.

Design: Retrospective cohort study.

Participants: One hundred forty treatment-naive patients 18 years or older with unilateral DMO presenting to Cole Eye Institute between January 2012 and July 2021.

Purpose: Oxidative stress-induced mitochondrial dysfunction is implicated in the pathogenesis of age-related macular degeneration (AMD). Oxidized mitochondrial flavoprotein fluorescence (FPF) may serve as a quantifiable biomarker of oxidative stress, reported as either mean score for the entire image (intensity) or variability (heterogeneity). This study examines FPF intensity and heterogeneity across a large patient cohort of various Beckman stages of AMD.

Background And Objective: To characterize treatment patterns for retinal vein occlusion (RVO)-related macular edema (ME) in routine clinical practice and its impact on long-term best-corrected visual acuity (BCVA) and central subfield thickness (CST).

Patients And Methods: Retrospective study of 365 eyes with branch RVO (BRVO) or central/hemi-RVO (CRVO/HRVO)-related ME between 2003 and 2020. Regression analysis identified factors associated with maintenance injection interval (MII).

Article Synopsis
  • - The study aimed to determine the average time patients with panretinal photocoagulation (PDR) take to develop vision-threatening retinopathy (VTR) complications after treatment, alongside identifying significant risk factors.
  • - Records from 220 patients who underwent complete PRP were reviewed, revealing that the average duration from PRP to VTR was about 1.25 years, with specific risk factors like age, Black race, and diabetic foot disease (DFD) significantly impacting this timeline.
  • - The findings suggest that DFD and Black race are important indicators for predicting the onset of VTR within 4 years post-PRP treatment, helping healthcare providers make better decisions in clinical practice.

Purpose: The purpose was to establish the position of the fovea centralis to the optic nerve via en-face, near-infrared spectral domain optical coherence tomography (NIR-OCT) in healthy patients. This may shed light on physiological variability and be used for studying subtle cases of foveal ectopia in macular pathology and after retinal detachment.

Methods: SD-OCT data of 890 healthy eyes were retrospectively analyzed.
