| Popis: | Purpose: We report a case of laser-induced retinopathy that posed diagnostic challenges with conventional spectral domain optical coherence tomography (SD-OCT), but was successfully diagnosed using adaptive optics-optical coherence tomography (AO-OCT). Observations: A 27-year-old man with a history of occupational laser device use presented with central scotoma and visual disturbances in the right eye. Conventional SD-OCT only revealed decreased reflectivity in parts of the foveal ellipsoidal zone band. However, other multimodal observations indicated damage to the retinal pigment epithelium (RPE) and choriocapillaris. Additionally, a well-defined circular, dark lesion, approximately 80 μm in diameter, was identified in the outer retina. AO-OCT demonstrated the absence of the RPE and Bruch's membrane, accompanied by the loss of inner and outer segments of cone photoreceptors and dropout of cone cell nuclei, with Müller cells remaining unaffected. Conclusions and Importance: This case of laser-induced retinopathy advances our understanding of the pathophysiological effect of laser exposure on the retina, suggesting a higher incidence of laser-induced retinopathy than previously diagnosed. It also serves as a crucial reminder for laser users to exercise caution and highlights the necessity for ophthalmologists to carefully observe and examine such cases. |
