Purpose: The region of growth (ROG) of geographic atrophy (GA) throughout the macular area has an impact on visual outcomes. Here, we developed multiple deep learning models to predict the 1-year ROG of GA lesions using fundus autofluorescence (FAF) images.

Design: In this retrospective analysis, 3 types of models were developed using FAF images collected 6 months after baseline to predict the GA lesion area (segmented lesion mask) at 1.

Modern mediation analysis techniques supplement the primary intention-to-treat analysis with the aim to shed light onto the treatment mechanism. We investigate to what extent the anatomic marker vitreomacular adhesion resolution (VMAR) mediates vision benefits, comparing ocriplasmin vs. a sham regimen.

Article Synopsis
  • The study focuses on evaluating the morphological changes in neovascular age-related macular degeneration (nAMD) during anti-angiogenic therapy and how these changes relate to visual acuity and the risk of developing macular atrophy (MA).
  • It utilized data from the HARBOR trial, analyzing SD-OCT scans from 1097 nAMD eyes to assess the impact of different treatment regimens and MNV subtypes on various retinal fluid volumes.
  • The findings indicate that higher initial volumes of intraretinal cystoid fluid and pigment epithelial detachment increase the likelihood of developing MA, while residual fluid volumes are linked to poorer visual outcomes over 24 months.

Purpose: To assess the associations between visual acuity (VA) and retinal thickness in age-related macular degeneration (AMD) eyes treated with anti-vascular endothelial growth factor (VEGF) therapy.

Methods: Sixty-eight patients with neovascular AMD (68 eyes) undergoing anti-VEGF therapy with two years of follow-up imaging data after the initiation of treatment were retrospectively included. Linear and nonlinear regression analyses with curve fitting estimation were performed to explore the relationship between visual acuity and OCT-based parameters at the 3-month and 24-month follow-up visits.

March 2023

Department of Ophthalmology, David Geffen School of Medicine at UCLA, UCLA Stein Eye Institute, Los Angeles, CA, USA.

Low-tension glaucoma can sometimes be difficult to diagnose, particularly if patients do not have a classic presentation. This case series shows the value of Humphrey visual field (HVF) 10-2 tests to identify deficits in central vision. Case 1 describes a female in her mid-60s who presented complaining of a "blind spot" in her right eye.

Vitelliform maculopathy: Diverse etiologies originating from one common pathway.

Surv Ophthalmol

May 2023

Retinal Disorders and Ophthalmic Genetics Division, Stein Eye Institute, University of California Los Angeles, Los Angeles, CA, USA; Greater Los Angeles Veterans Affairs Healthcare Center, Los Angeles, CA, USA. Electronic address:

Vitelliform lesions (VLs) are associated with a wide array of macular disorders but are the result of one common pathway: retinal pigment epithelium (RPE) impairment and phagocytic dysfunction. VLs are defined by the accumulation of yellowish subretinal material. In the era of multimodal advanced retinal imaging, VLs can be further characterized by subretinal hyperreflectivity with optical coherence tomography and hyperautofluorescence with fundus autofluorescence.

The Henle fiber layer (HFL) is comprised of bundles of unmyelinated photoreceptor axons intermingled with outer Müller cell processes. The photoreceptor axons extend from the cell bodies located in the outer nuclear layer and radially project toward the outer plexiform layer, the inner third of which includes the synaptic junctional complexes and the outer two-thirds of which includes the HFL. The oblique path of the HFL provides unique structural and reflectance properties and this radial anatomy is highlighted in many macular disorders including those with macular star exudation and HFL hemorrhage.

Neovascular age-related macular degeneration (nAMD) is a common world-wide cause of visual loss. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents are an effective means to treat nAMD and reduce its impact on vision compared to either sham treatment or photodynamic therapy. Currently, the approved anti-VEGF drugs include ranibizumab, aflibercept and brolucizumab.
