Photic retinopathy is damage to the eye's retina, particularly the macula, from prolonged exposure to solar radiation or other bright light, e.g., lasers or arc welders.The term includes solar, laser, and welder's retinopathy and is synonymous with retinal phototoxicity. [1]
Long-term systemic Immunosuppressive therapy is the main treatment of cancer-associated retinopathy. [5] It can be treated with a combination of chemotherapy and immunosuppression. [2] Although tumor removal and cancer regression may result in a decrease in circulating autoantibodies, this does not influence CAR progression. [8]
Blue light, a type of high-energy light, is part of the visible light spectrum. High-energy visible light (HEV light) is short-wave light in the violet/blue band from 400 to 450 nm in the visible spectrum, which has a number of purported negative biological effects, namely on circadian rhythm and retinal health (blue-light hazard), which can lead to age-related macular degeneration.
Retinal regeneration in zebrafish is mediated by Muller glia, which dedifferentiate into stem-like cells and proliferate into neural progenitor cells in response to retinal damage. While Muller glia division is responsible for the regeneration of the retina in all cases of retinal damage, the case of photoreceptor loss due to light damage is ...
Studies have been performed on the use of shortwave radiation for cancer therapy and promoting wound healing, with some success. However, at a sufficiently high energy level, shortwave energy can be harmful to human health, potentially causing damage to biological tissues, for example by overheating or inducing electrical currents.
