Corneal alkali wound healing in the monkey.
Healing of a corneal alkali wound was followed in the monkey eye (Macaca fascicularis) for 4 months. A corneal alkali wound was inflicted in one eye in each of 30 monkeys under general anesthesia. A round filter paper, 5.5 mm in diameter, soaked in 1 N NaOH was put centrally on the cornea for 60 seconds. The alkali wounded all layers in the cornea underlying the filter paper, including the endothelium. Epithelial and endothelial healing was assessed morphometrically from photographs and micrographs, respectively. Stromal healing was documented using quantitative microradiography. During the observation period the wounds regained complete transparency. The epithelium showed few complications after primary healing during the first three days. The stroma regained normal thickness and dry mass content within one week. The endothelium resurfaced within one week and then remained intact. The role of the endothelial healing behaviour for the wound healing process is emphasized.
