[Wound healing in the feline retina following mechanical trauma (author's transl)].

The healing of superficial retinal scratches inflicted with a Sato knife was followed from days 1 to 135 in 20 domestic cats. Breakdown of retinal tissue continued for 18 weeks. Glial proliferation was extremely sparse and never observed before day 6. Microvilli and cell processes, derived mainly from Müller cells, were also seen in the wound. Regeneration of the internal limiting membrane was never observed. The choroid, pigment epithelium, retinal blood vessels, and vitreous played no part in the healing process.
