Ophthalmic evaluations. The light-irradiated eyes did not have corneal edema, corneal vascularization, corneal melanosis, uveitis, or iritis (Figure 1). One animal had conjunctival hyperemia and edema in the light-irradiated eye. No structural damage to the general fundus, including the optic disc and the retinal and choroidal vasculature, was observed after light irradiation.
