Introduction: The aim of this study was to evaluate the progression of atrophy as determined by spectral-domain optical coherence tomography (SD-OCT) in patients with molecularly confirmed ABCA4-associated Stargardt disease type 1 (STGD1) over a 24-month period in a multicenter prospective cohort study.

Methods: SD-OCT images from 428 eyes of 236 patients were analyzed. Change of mean thickness (MT) and intact area were estimated after semiautomated segmentation for the following individual layers in the central subfield (CS), inner ring (IR), and outer ring (OR) of the ETDRS grid: retinal pigment epithelium (RPE), outer segments (OSs), inner segments (IS), outer nuclear layer (ONL) inner retina (IR), and total retina.

Electronic address:

Article Synopsis
  • The study examines the characteristics of patients with inherited retinal diseases caused by RDH5 and RLBP1 gene variants, aiming to establish genotype-phenotype correlations.
  • A total of 27 patients were analyzed, with results indicating significant macular atrophy (MA) in about 80% of cases, and a notable difference in macular volume loss between the two genotypes.
  • Findings suggest that RDH5-related conditions lead to progressive MA and night blindness, while certain RLBP1 variants may result in milder symptoms, which could inform treatment approaches and patient prognoses.

Radiation retinopathy (RR) is a major side effect of ocular tumor treatment by plaque brachytherapy or proton beam therapy. RR manifests as delayed and progressive microvasculopathy, ischemia and macular edema, ultimately leading to vision loss, neovascular glaucoma, and, in extreme cases, secondary enucleation. Intravitreal anti-VEGF agents, steroids and laser photocoagulation have limited effects on RR.

Article Synopsis
  • P-glycoprotein (P-gp) is a crucial transporter that controls the entry of drugs and other substances into the brain by limiting their passage across the blood-brain barrier (BBB).
  • This protein can be influenced by drug interactions, aging, and neurodegenerative diseases, making its study particularly important for older adults.
  • Recent advancements in neuroimaging techniques are enhancing our ability to study P-gp activity in real-time, providing new insights into its role in health and disease.

Article Synopsis
  • The study aimed to examine how blood pressure (BP) changes throughout the day and night in patients with non-arteritic anterior ischemic optic neuropathy (NAION).
  • 65 patients with acute NAION underwent 24-hour ambulatory blood pressure monitoring (ABPM), using different definitions for nighttime periods to classify their BP patterns.
  • Results showed a high prevalence of extreme dippers (23%) during the strictest nighttime definition, and many patients (39%) without known hypertension were found to have elevated BP, indicating that ABPM is important for assessing BP in NAION patients.

Coding and non-coding variants in the ciliopathy gene cause early-onset non-syndromic retinal degeneration.

Res Sq

February 2024

Ocular Genomics Institute, Massachusetts Eye and Ear Infirmary, Department of Ophthalmology, Harvard Medical School, Boston, MA, USA.

Inherited retinal degenerations are blinding genetic disorders characterized by high genetic and phenotypic heterogeneity. The implementation of next-generation sequencing in routine diagnostics, together with advanced clinical phenotyping including multimodal retinal imaging, have contributed to the increase of reports describing novel genotype-phenotype associations and phenotypic expansions. In this study, we describe sixteen families with early-onset non-syndromic retinal degenerations in which affected probands carried rare bi-allelic variants in , a ciliary gene previously associated with syndromic recessive Jeune syndrome.

Objectives: To evaluate the validity and reliability of the new Fast Assessment of the Ocular Surface Trouble (FAST®) questionnaire for identifying glaucoma or ocular hypertension (OHT) patients at risk of ocular surface disease (OSD).

Methods: A multicenter, international, cross-sectional, epidemiological survey evaluated the most accurate interview items and ocular signs on the initial 14-item version of FAST® to develop a shorter version for routine, quick clinical use. Rasch analysis and least absolute shrinkage and selection operator (LASSO) method was used to reduce the number of items on the questionnaire.

Article Synopsis
  • The study focuses on inherited retinal degenerations (IRDs) that can lead to blindness, particularly investigating genetic variations in a North African cohort, which has been less studied compared to European and Asian populations.
  • Researchers used advanced sequencing techniques and expression analyses on various cell types to identify a new gene defect in the UBAP1L gene in four cases of autosomal recessive IRD from Tunisia.
  • Findings suggest that these biallelic UBAP1L variants play a significant role in IRDs, indicating a potential genetic prevalence in the North African population.

Age-related macular degeneration (AMD) is invariably associated with the chronic accumulation of activated mononuclear phagocytes in the subretinal space. The mononuclear phagocytes are composed of microglial cells but also of monocyte-derived cells, which promote photoreceptor degeneration and choroidal neovascularization. Infiltrating blood monocytes can originate directly from bone marrow, but also from a splenic reservoir, where bone marrow monocytes develop into angiotensin II receptor (ATR1) splenic monocytes.

Corneal neuroepithelial compartmentalized microfluidic chip model for evaluation of toxicity-induced dry eye.

Part of the lacrimal functional unit, the cornea protects the ocular surface from numerous environmental aggressions and xenobiotics. Toxicological evaluation of compounds remains a challenge due to complex interactions between corneal nerve endings and epithelial cells. To this day, models do not integrate the physiological specificity of corneal nerve endings and are insufficient for the detection of low toxic effects essential to anticipate Toxicity-Induced Dry Eye (TIDE).

Glaucoma is a chronic optic neuropathy characterized by progressive sclero-laminar remodeling. The main factor at the origin of these deformations is the intraocular pressure (IOP), the effect of which varies according to the biomechanical properties of the individual lamina cribrosa (LC). In this environment, the LC represents a malleable zone of weakness within a rigid corneoscleral shell.

A new method for in vivo assessment of corneal transparency using spectral-domain OCT.

PLoS One

November 2023

Laboratory for Optics and Biosciences (LOB)- École Polytechnique, CNRS, INSERM, IPP, Palaiseau, France.

Corneal transparency is essential to provide a clear view into and out of the eye, yet clinical means to assess such transparency are extremely limited and usually involve a subjective grading of visible opacities by means of slit-lamp biomicroscopy. Here, we describe an automated algorithm allowing extraction of quantitative corneal transparency parameters with standard clinical spectral-domain optical coherence tomography (SD-OCT). Our algorithm employs a novel pre-processing procedure to standardize SD-OCT image analysis and to numerically correct common instrumental artifacts before extracting mean intensity stromal-depth (z) profiles over a 6-mm-wide corneal area.

Background: Peripheral ulcerative keratitis (PUK) is a group of inflammatory corneal ulcers with stromal thinning and peripheral localization. Amniotic membranes (AM) are used for their anti-inflammatory and healing properties. A freeze-drying process now allows maintaining the AM viable for a long time at room temperature without altering its physical, biological, and morphologic characteristics.
