Wide-Field Optical Coherence Tomography Imaging Improves Rate of Change Detection in Progressing Glaucomatous Eyes Compared With Standard-Field Imaging.

Invest Ophthalmol Vis Sci

July 2024

Hamilton Glaucoma Center, Shiley Eye Institute, The Viterbi Family Department of Ophthalmology, University of California San Diego, La Jolla, California, United States.

Purpose: To compare rates of retinal nerve fiber layer change over time in healthy, eyes with nonprogressing glaucoma and eyes with progressing glaucoma using single wide-field (SWF) and optic nerve head (ONH) cube scan optical coherence tomography (OCT) images.

Methods: Forty-five eyes of 25 healthy individuals and 263 eyes of 161 glaucoma patients from the Diagnostic Innovations in Glaucoma Study were included. All eyes underwent 24-2 visual field testing and OCT (Spectralis SD-OCT) ONH and macular imaging.

High Myopia Normative Database of Peripapillary Retinal Nerve Fiber Layer Thickness to Detect Myopic Glaucoma in a Chinese Population.

Ophthalmology

December 2023

State Key Laboratory of Ophthalmology, Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangdong Provincial Key Laboratory of Ophthalmology and Visual Science, Guangdong Provincial Clinical Research Center for Ocular Diseases, Guangzhou, China. Electronic address:

Article Synopsis
  • The study aimed to create and validate a specialized database to help differentiate between high myopia (HM) and highly myopic glaucoma (HMG) by measuring the thickness of the peripapillary retinal nerve fiber layer (pRNFL).
  • It involved 1367 participants, analyzing pRNFL thickness using advanced optical coherence tomography (OCT) and included robust quality control measures to ensure reliability in results.
  • The findings showed that the HM-specific normative database could accurately detect HMG, achieving high accuracy and specificity rates, especially when using the fifth percentile as a threshold for pRNFL thickness.

Anti-vascular endothelial growth factor (anti-VEGF) therapies have become the standard of care in the treatment of neovascular age-related macular degeneration (nAMD) and diabetic macular edema (DME), resulting in a remarkable decrease in disease-related vision loss. However, the need for regular injections places a significant burden on patients, caregivers, and the healthcare system and improvements in vision may not be maintained long term. As a result of its drying potency and duration of action, brolucizumab, an intravitreal anti-VEGF therapy approved for the treatment of nAMD and DME, could decrease injection frequency for patients and provide an efficacious treatment; however, balancing its benefits and risks can be challenging.

Ophthalmology faces many challenges in providing effective and meaningful eye care to an ever-increasing group of people. Even health systems that have so far been able to cope with the quantitative patient increase, due to their funding and the availability of highly qualified professionals, and improvements in practice routine efficiency, will be pushed to their limits. Further pressure on care will also be caused by new active substances for the largest group of patients with AMD, the so-called dry form.

Uveal melanoma (UM) is the most common primary intraocular tumor in adults. New diagnostic procedures and basic science discoveries continue to change our patient management paradigms. A recent meeting of the European Vision Institute (EVI) special interest focus group was held on "Outcome Measures of New Technologies in Uveal Melanoma," addressing the latest advances in UM, starting with genetic developments, then moving on to imaging and treatment of the primary tumor, as well as to investigating the most recent developments in treating metastases, and eventually taking care of the patient's well-being.

Progression of Retinopathy Secondary to Maternally Inherited Diabetes and Deafness - Evaluation of Predicting Parameters.

Am J Ophthalmol

May 2020

Moorfields Eye Hospital NHS Foundation Trust, London, United Kingdom; Institute of Ophthalmology, University College London, London, United Kingdom. Electronic address:

Article Synopsis
  • - The study aimed to evaluate how demographic, functional, and imaging factors influence the progression of retinal pigment epithelium (RPE) atrophy in patients with maternally inherited diabetes and deafness (MIDD), and to inform clinical trial designs based on these findings.
  • - Researchers analyzed data from 35 eyes of 20 patients over an average of 4.27 years, discovering that larger baseline lesion sizes correlated with faster progression rates of RPE atrophy, while the foveal area remained mostly preserved.
  • - Results indicated that demographic factors like sex and age, as well as the number of atrophic spots, could help predict future rates of progression, aiding in the optimization of subject selection and reducing sample sizes for future

Novel diagnostic tools to measure retinal function and structure are rapidly being developed and introduced into clinical use. Opportunities exist to use these informative and robust measures as endpoints for clinical trials to determine efficacy and to monitor safety of therapeutic interventions. In order to inform researchers and clinician-scientists about these new diagnostic tools, a workshop was organized by the European Vision Institute.
