Purpose:
Clinical investigation of central retinal dysfunction in two cases of solar retinopathy.
Methods:
Two patients were examined for best corrected visual acuity (VA), fundus inspection, visual fields, multifocal electroretinography (mfERG) with a stimulus pattern of 241 hexagons and, at follow-up, also with optical coherence tomography (OCT).
Results:
At the initial examination, mfERG revealed 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 reduced. In Case 2, OCT showed spots of increased reflectivity corresponding to the patient's symptoms.
Conclusion:
Central retinal dysfunction due to solar retinopathy may improve over time. However, structural and functional changes may persist. This report illustrates that mfERG and OCT are useful tools for objective documentation of the pathology in solar retinopathy.
