Abstract
The cornea of 1 eye was opacified in 2 young macaques by multiple stromal injections of a suspension of polystyrene particles (latex). Ultrasound measurements showed that the eye with opaque cornea grew at a faster rat. After 1 yr it was more than 1 mm longer than the normal eye. This difference in axial length was due to elongation of the posterior segment, since lens thickness, depth of anterior chamber and corneal curvature were identical in both eyes. A histological examination revealed no pathological changes in the anterior segment of the latex-injected eye except for a scant vascularization of the corneal opacity. Opacification of the cornea effects axial length similar to, but less than, lid fusion. Myopia caused by lid fusion apparently is triggered by abnormal visual input and involves central visual pathways.
