The multifocal electroretinogram in central serous chorioretinopathy.
OBJECTIVE
To compare multifocal electroretinograms (ERGs) in control subjects and patients with central serous chorioretinopathy (CSC).


METHODS
Eighteen eyes of control subjects and 15 eyes affected by CSC were tested with a VERIS Sciences 4.0 system. The average response densities and latencies of six annular retinal regions in control subjects were compared with those with CSC.


RESULTS
The N1, P1 average response densities of the first and second annuli were decreased and the N1, P1 latencies of first to third rings were delayed in CSC.


CONCLUSIONS
The multifocal ERG can be used to evaluate retinal dysfunction in CSC.
