Abstract

The eye is an easily accessible, highly compartmentalised and immune-privileged organ that offers unique advantages as a gene therapy target. Significant advancements have been made in understanding the genetic pathogenesis of ocular diseases, and gene replacement and gene silencing have been implicated as potentially efficacious therapies. Recent improvements have been made in the safety and specificity of vector-based ocular gene transfer methods. Proof-of-concept for vector-based gene therapies has also been established in several experimental models of human ocular diseases. After nearly two decades of ocular gene therapy research, preliminary successes are now being reported in phase 1 clinical trials for the treatment of Leber congenital amaurosis. This review describes current developments and future prospects for ocular gene therapy. Novel methods are being developed to enhance the performance and regulation of recombinant adeno-associated virus- and lentivirus-mediated ocular gene transfer. Gene therapy prospects have advanced for a variety of retinal disorders, including retinitis pigmentosa, retinoschisis, Stargardt disease and age-related macular degeneration. Advances have also been made using experimental models for non-retinal diseases, such as uveitis and glaucoma. These methodological advancements are critical for the implementation of additional gene-based therapies for human ocular diseases in the near future.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • AAVs generate relatively mild innate and adaptive immune responses, which allow for stable long-term transgene expression.

    “Unlike adenoviruses, AAVs generate relatively mild innate and adaptive immune responses, which allow for stable long-term transgene expression.”

    From Ocular Gene Therapy: A Literature Review with Special Focus on Immune and Inflammatory Responses (2022) · cites this paper as [15]

    The Ocular Gene Transfer Methods section says AAV vectors typically elicit minimal immune responses and allow stable, long-term transgene expression, while adenoviral vectors elicit robust immune responses that limit expression. It does not distinguish AAV’s innate from adaptive immune responses, so that specificity is not established by our copy. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • The small size, accessibility, confined structure, and immune-privileged status of the eye make it an ideal target for gene therapy.

    “The small size, accessibility, confined structure, and immune-privileged status of the eye [74, 75], make it an ideal target for gene therapy”

    From The economic impact of retinal diseases for which gene therapy is emerging: a systematic literature review (2025) · cites this paper as [74]

    The Abstract (page unavailable) describes the eye as accessible, compartmentalised and immune-privileged, and says these features offer advantages for gene therapy. It does not identify the eye’s small size as one of those advantages. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Longer-acting treatments such as gene therapy are sought to address the absences and inadequacies of currently available treatments in retinal diseases.

    “To address these absences and inadequacies of currently available treatments in retinal diseases, longer-acting treatments such as gene therapy, are sought [74].”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
