[Adenoma of the pigmented epithelium of the iris with endothelialization and descemetization in the horse].

The authors describe peculiar tumors with brown-white piebald anterior surface, which had grown bilaterally from the corpora nigra (C.N.) of an adult horse and occluded the pupils.

[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.

[Findings on retinal surface by scanning electron microscopy. III. Epivascular glial clusters (author's transl)].

The findings by scanning and transmission electron microscopy of multiple glial excrescences from the retina into the cortical vitreous body are described. These formations are located in lines above superficial retinal vessels. The findings are compared with those from light microscopy of similar formations.

[Findings on retinal surface by scanning electron microscopy. II. Vitreous detachment (author's transl)].

The authors describe their findings by scanning electron microscopy of the surface of the retina following secondary and primary senile posterior vitreous detachment. These findings are correlated with those of transmission electron microscopy. Extended nets formed by vitreous fibrils can be found on the retinal surface.
