Abstract
BACKGROUND
Light-induced retinal damage is a serious vision-threatening disease, resulting from unsuitable laser irradiation, high-power light and sustaining light exposure. Therefore, effectively evaluate the morphological and functional of retinal damage is urgently needed. Now, we mainly reported three patients suffered from typical light irradiations.
CASE SUMMARY
Patient 1 suffered from old laser pointer irradiation and followed with amblyopia treatment. Patient 2 suffered from acute high-energy light irradiation. Patient 3 suffered from sustaining optical fiber irradiation. Detailed morphological and functional examinations of the retina revealed that the lesions of the three patients had many similar characteristics, such as macular morphological changes, patent pattern visual monitoring amplitude or peak time abnormalities, multi-fucus electroretinograms macular central amplitude density decreased.
CONCLUSION
In conclusion, light-induced retinopathy has many common features, which can help clinical medical staff to diagnose retinal photodamage diseases.
Core Tip: In this case report, we reported three typical cases of retinal damage caused by light-related irradiations. Through the summary of their common characteristics, we can deepen the understanding of retinal diseases caused by light irradiation, and provide theoretical basis for the prevention, clinical diagnosis and treatment of such diseases.
