Techniques for subretinal injections in animals

Veterinary Ophthalmology, Volume 28, Issue 2, Page 506-518, March 2025.
Abstract Subretinal injections are not commonly performed during clinical treatment of animals but are frequently used in laboratory animal models to assess therapeutic efficacy and safety of gene and cell therapy products. Veterinary ophthalmologists are often employed to perform the injections in the laboratory animal setting, due to knowledge of ...

Scleral surgery for the treatment of presbyopia: where are we today?

Eye and Vision, 2018
Presbyopia corrections traditionally have been approached with attempts to exchange power, either at the cornea or the lens planes, inducing multifocality, or altering asphericity to impact the optical system. Treatments that affect the visual axis, such

Reconstruction of deep and perforating corneal defects in dogs—A review (Part II/III): Biomaterials and keratoprosthesis

Veterinary Ophthalmology, Volume 28, Issue 2, Page 532-542, March 2025.
Abstract The surgical reconstruction of severe corneal ulcers is a common and crucial component of the clinical practice of veterinary ophthalmology. Numerous surgical techniques are used in dogs for corneal reconstruction, and these techniques may be categorized by the material used to repair the corneal lesion.
