20.2 Retinal Light Toxicity (Photochemical) Introduction: Accidental light-induced injuries to the retina from a photochemical mechanism can occur from prolonged exposure to the sun, from a welding arc, and from intra-operative microscope illumination. Clinical Features: Retinal phototoxicity from the sun or a welding arc appears as small, round, well-circumscribed, yellow acquired vitelliform-like lesions in the fovea (Fig. 20.2.1). Microscope phototoxicity appears as a more broad area that is fairly well-circumscribed either in the inferior or superior macula (dependent on tilt of microscope).
