Photobiomodulation protects photoreceptor ultrastructure in methanol-intoxicated rats. Electron micrographs of the rod inner segment region in representative untreated control (A), LED control (B), methanol-intoxicated (C), and LED-treated, methanol-intoxicated (D) rats. The arrows indicate abnormal mitochondrial morphology in photoreceptor inner segments. Photoreceptor mitochondria from LED control or LED-treated, methanol-intoxicated rats exhibited normal morphology with well-defined cristae. (Magnifications: ×5,000.)
