Objective: To explore the multifocal electroretinogram in patients with nonproliferative diabetic retinopathy with clinically-significant macular edema.
Methods: Forty-one eyes with clinically significant macular edema were tested. The latencies and amplitudes of average responses of 5 eccentric rings from 0 to 26 degrees relative to the fixation point were compared with normal values obtained from 13 nondiabetic subjects.
Results: Local electroretinogram responses were significantly delayed and decreased in amplitude in patients with clinically-significant macular edema.
Conclusion: Multifocal electroretinogram can be used to quantify the visual function in clinically significant macular edema.

The aim of this study is to describe genotype and phenotype of patients with bestrophinopathy. The case records were reviewed retrospectively, findings of multimodal imaging such as color fundus photograph, optical coherence tomography (OCT), fundus autofluorescence, electrophysiological, and genetic tests were noted. Twelve eyes of six patients from distinct Indian families with molecular diagnosis were enrolled.

Although hydroxychloroquine (HCQ) is used to treat systemic lupus erythematosus (SLE), it is associated with retinal toxicity. Early diagnosis can prevent the further progression of HCQ-associated retinopathy by discontinuing HCQ treatments. This study aimed to evaluate the early diagnostic parameters in patients with SLE treated with HCQ and identify the best approach using multifocal electroretinography (mfERG) and swept-source optical coherence tomography (SS-OCT) to reflect subclinical retinal toxicity.

Article Synopsis
- A 25-year-old man diagnosed with retinitis pigmentosa (RP) showed distinct posterior segment abnormalities during examination, including bone spicule pigmentation and retinal atrophy.
- Findings from advanced imaging techniques like optical coherence tomography (OCT) revealed unique wavy protrusions on the inner retinal surface, leading to non-cystic petaloid maculopathy and changes in choroidal thickness.
- The patient's condition not only highlighted the retinal involvement linked to a genetic variant but also raised concerns about potential syndromic associations, including a major depressive disorder requiring hospitalization.
Multifocal Electroretinography Changes in Patients with Late-Stage Age-Related Macular Degeneration (AMD) After Smaller-Incision New-Generation Implantable Miniature Telescope (SING IMT): A Case Series.

The smaller-incision new-generation implantable miniature telescope (SING IMT) represents an advancement over the previous model, WA-IMT, serving as a unilateral prosthetic device for patients with late-stage age-related macular degeneration (AMD). This study aims to report changes in multifocal electroretinography (mfERG) 6 months post-SING IMT implantation. In this case series, we prospectively evaluated a cohort of phakic patients with late-stage AMD who underwent SING IMT implantation at the Ophthalmology Unit, University of Bari Aldo Moro, Italy.

Introduction: Annual screening for hydroxychloroquine (HCQ) retinopathy is recommended, and electroretinography (ERG) is considered a gold-standard test, but there are screening shortfalls and standard ERG is burdensome and has limited availability. Newer, portable ERG devices using skin-based electrodes may increase screening capacity but need validation. This study aims to determine initial device accuracies and feasibility of further research.
