摘　　要：Purpose: Clinical investigation of central retinal dysfunction in two cases of solar retinopathy. Methods: Two patients were examined for best corrected visua l acuity (VA), fundus inspection, visual fields, multifocal electroretinography (mfERG) with a stimulus pattern of 241 hexagons and, at follow-up, also with op tical coherence tomography (OCT). Results: At the initial examination, mfERG rev ealed central retinal dysfunction, which had improved by the time of follow-up. In Case 1, a foveal oedema regressed over time, although VA remained slightly r educed. In Case 2, OCT showed spots of increased reflectivity corresponding to t he patient’s symptoms. Conclusion: Central retinal dysfunction due to solar ret inopathy may improve over time. However, structural and functional changes may p ersist. This report illustrates that mfERG and OCT are useful tools for objectiv e documentation of the pathology in solar retinopathy.Purpose: Clinical investigation of central retinal dysfunction in two cases of solar retinopathy.
