[Multifocal electroretinogram for assessing sun damage following the solar eclipse of 11 August 1999].

Following the eclipse of 11 August 1999, the ophthalmological clinic of Strasbourg cared for 4 patients who suffered from sun damage. The multifocal electroretinogram (ERG) carried out on our first patient enabled us to not only confirm the existence of a residual maculopathy as shown by the static visual field, but also, and above all to quantify the foveolar deficit. Moreover, with the other 3 patients, the multifocal ERG enabled us to detect a foveolar deficit completely overlooked by the other usual tests. In light of our clinical study, we can assert that the multifocal ERG has yet to be equaled by any other test for analysis of macular function.
