Purpose Of Review: The aim of this article is to review the controversial findings for NovaVision's vision restoration therapy.
Recent Findings: It has been claimed that NovaVision's computerized therapy results in expansion of the visual field in optic nerve and occipital lesions, but the outcome has been challenged on the grounds of unsatisfactory perimetric control of central fixation and disputed mechanisms.
Summary: In clinical practice NovaVision's therapy should not currently gain acceptance in view of unacceptable perimetric standards and equivocal results. Possible effects on a relative scotoma at the edge of a lesion have not been adequately explored. In the interim, research should also be focused on compensatory eye movement strategies.

ENHANCED RESTORATION OF VISUAL CODE AFTER TARGETING ON BIPOLAR CELLS COMPARED TO RETINAL GANGLION CELLS WITH OPTOGENETIC THERAPY.

Optogenetic therapy is a promising vision restoration method where light sensitive opsins are introduced to the surviving inner retina following photoreceptor degeneration. The cell type targeted for opsin expression will likely influence the quality of restored vision. However, a like-for-like pre-clinical comparison of visual responses evoked following equivalent opsin expression in the two major targets, ON bipolar (ON BCs) or retinal ganglion cells (RGCs), is absent.

We have previously shown that the transplantation of stem cell-derived retinal organoid (RO) sheets into animal models of end-stage retinal degeneration can lead to host-graft synaptic connectivity and restoration of vision, which was further improved using genome-edited Islet1 ROs (gROs) with a reduced number of ON-bipolar cells. However, the details of visual function restoration using this regenerative therapeutic approach have not yet been characterized. Here, we evaluated the electrophysiological properties of end-stage rd1 retinas after transplantation (TP-rd1) and compared them with those of wild-type (WT) retinas using multi-electrode arrays.

Camera traps are widely used in wildlife research and monitoring, so it is imperative to understand their strengths, limitations, and potential for increasing impact. We investigated a decade of use of wildlife cameras (2012-2022) with a case study on Australian terrestrial vertebrates using a multifaceted approach. We (i) synthesised information from a literature review; (ii) conducted an online questionnaire of 132 professionals; (iii) hosted an in-person workshop of 28 leading experts representing academia, non-governmental organisations (NGOs), and government; and (iv) mapped camera trap usage based on all sources.

Background: To investigate the impact of central corneal astigmatism on postoperative visual outcomes in patients with trifocal intraocular lens (IOL) implantation.
Methods: This retrospective study included 278 eyes of 278 patients who underwent uneventful cataract surgery with implantation of the trifocal IOL (AT LISA tri 839MP). Patients were divided into two groups according to the total corneal refractive power (TCRP) in 3 mm zone centered on the corneal apex: low astigmatism group, TCRP ≤ 0.
Diabetes Endothelial Keratoplasty Study: Methods and Impact on the Use of Corneas From Donors With Diabetes for Descemet Membrane Endothelial Keratoplasty.

Department of Ophthalmology and Visual Sciences, Case Western Reserve University School of Medicine, University Hospitals Eye Institute, Cleveland, OH.
Purpose: Describe aims, methods, characteristics of donors, donor corneas and recipients, and potential impact of the Diabetes Endothelial Keratoplasty Study (DEKS).
Methods: The DEKS is a randomized, clinical trial to assess graft success and endothelial cell density (ECD) 1 year after Descemet membrane endothelial keratoplasty (DMEK) using corneas from donors with versus without diabetes in a 1:2 minimization assignment. Diabetes severity in the donor is assessed by medical history, postmortem HbA1c, and donor skin advanced glycation end-products and oxidation markers.
