Purpose. To investigate the functional characteristics of the detached retina on a serous retinal detachment (SRD) in eyes with central serous chorioretinopathy (CSC) with spared visual acuity. Methods. Multifocal electroretinograms (mfERGs) were recorded with a long recording time of 14 minutes, 34 seconds, to obtain accurate measurement of the second-order kernel (K2.1), an index of functional adaptability of the retina, from seven eyes with CSC (visual acuity, >1.0). The first-order kernel (K1) and the K2.1, elicited by stimulating the area of the SRD, were compared with those from the corresponding areas in eyes of 15 age-matched volunteers (controls) and in 6 eyes of patients with diabetic retinopathy (DR) that have been reported to have a K2.1 attenuation. Results. K2.1 was essentially flat in the SRD eye. The K2.1 amplitude and log-scaled amplitude ratio of K2.1 to K1 (K2.1/ K1) were severely reduced (to <95% confidence interval [CI] of control levels) in all eyes. The value of K2.1/K1 of the SRD was less than that in any of the control and DR eyes. K1 was moderately reduced but was not smaller than the 95% CI of control eyes. The mfERGs from the area without the SRD and those from the fellow eyes did not differ significantly from those in control eyes. Conclusions. A possible cause of the flat K2.1 observed on the SRD is the separation of the sensory retina. A substantial disparity between the recovery of cones and rods could contribute to the loss of retinal adaptability, resulting in the flat K2.1 as well as the unique visual impairments in CSC eyes.
