Purpose: To assess retinal function in the posterior pole of eyes with central serous chorioretinopathy with multifocal electroretinogram. Methods: Multifocal electroretinograms (mfERG) were recorded in 24 patients (19 males and 5 females) diagnosed as central serous chorioretinopathy (CSC) with fluorescein angiogram (FAG) and 24 normal control subjects. The central 30 degrees of ocular fundus was stimulated by an array of 103 hexagonal elements for four minutes. The waveforms of the first and second order kernel responses in the affected and fellow eyes were compared with normal controls. The mfERG responses of five concentric rings radiating from the foveal center were averaged. Results: FAG showed central macular detachments in the affected eyes of all patients, while the fellow eyes were normal. Amplitudes of both affected and fellow eyes were significantly decreased in the entire test field of retina compared with normal controls (p<0.05), while latencies increased (p<0.05). The responses of central concentric rings were more affected than peripheral concentric rings. Conclusions: Not only the affected eyes but fellow eyes of the patients with CSC had abnormal responses in the first and second kernel. These results suggest that fellow eyes possibly had underlying pathologic conditions in the retina. mfERG may be useful in evaluating the retinal function of fellow eyes with CSC patients.
